# Version 7.33 (2002-11-18)

The 7.33 release is the third, and hopefully final, beta in the series leading up to 8.0. This version contains a fix to the filename permissions logic.

The following SourceForge bug numbers were open at the time of this release: 405342, 407342, 414947, 414985, 446344, 458261, 458775, 458780, 459647, 465936, 484752, 484753, 487953, 493348, 505429, 510808, 526099, 526491, 530011, 535366, 535752, 535836, 538033, 539239, 546823, 554076, 558151, 558435, 563287, 569573, 570772, 573744, 578838, 578865, 584990, 592160, 592837, 592841, 592925, 592930, 595760, 596009, 598014, 600288, 601255, 601336, 601694, 602995, 603934, 605830, 607425, 607850, 610356, 610478, 610727, 611694, 611701, 611727, 611898, 612801, 614298, 615165, 616970, 616976, 617077, 617523, 621243, 621246, 623122, 623292, 623989, 624515, 625085, 626059, 626295, 626358, 626419, 2002-1, 626464, 627545, 628110, 629335, 631974, 633299, 634036, 634080, 634358, 634514, 636210, 637424, 637954, 638850, 640159.

## Procedures

    Fixes problems:
    	- The '-r' option works differently between Info-Zip ans Winzip
    "wzzip" Removal of this option allows wzzip to be used as well.
    (winint.mak [1.17]: 2002/11/04 22:54:47 ray)

    Post-release cleanup for 7.32: increment version number to 7.33.
    (version.mak [1.56]: 2002/11/05 08:31:56 raph)

    Add a revision 'id' line to the drawafm script. (toolbin/drawafm.ps [1.2]:
    2002/11/05 16:59:55 giles)

    Add a simple script for comparing font metric files. Currently it's only
    useful for sorting the font info and character metric data.
    (toolbin/afmutil.py [1.1]: 2002/11/07 14:10:13 giles)

    Skip blank lines in parsing afm files. (toolbin/afmutil.py [1.2]: 2002/11/14
    17:01:38 giles)

    First commit of 7.33 beta release: update dates and version numbers, edits
    to News.htm. (version.mak [1.57]: 2002/11/18 21:41:51 raph)

## Utilities

    Fixes problems:
    	- Fix (FAPI) : Improving terminology in header comment to
    lib/xlatmap . (lib/xlatmap [1.7]: 2002/11/02 18:03:06 igor)
    	- remove the unused SYSTIME_H from the mac headers. Prefer "time_.h"
    to <sys/time.h>. Although the Metroworks Standard Library doesn't have
    a sys/time.h, keep the definition of HAVE_SYS_TIME_H for now to avoid a
    multiple definition problem with struct timeval. (gp_mac.c [1.10]:
    2002/11/14 16:55:21 giles)
    	- correct an unitialized variable in the mac stream process.
    (gp_macio.c [1.9]: 2002/11/14 17:12:53 giles)
    	- Replace the previous gp_file_name_is_absolute with
    gp_patshtring_not_bare which generally has the same sense, but is more
    consistently implemented on platforms and indicates whether or not a
    pathstring can be prefixed by a directory and the path_separator string.
    Also, fix check_file_permissions to handle the 'bare' pathstring case when
    the current directory is one of the permitted paths. Fixes SourceForge bug
    #637751. (gp_iwatc.c [1.11], gp_macio.c [1.10], gp_mswin.c [1.14],
    gp_ntfs.c [1.11], gp_os2.c [1.16], gp_vms.c [1.14]: 2002/11/17 22:50:32 ray)

## Drivers

    Fixes problems:
    	- Make gdev_t4693d_map_color_rgb a functinal routine. Previously it
    returned a constant maximum color value. This would cause problems with
    overprint and anti-aliasing. (gdev4693.c [1.8]: 2002/11/13 19:34:56 dan)
    	- Update the encode/decode color procedures when the device is
    openned. This is required since the device can modify its model settings
    inside the open procedure. (gdevstc.c [1.8]: 2002/11/13 19:39:12 dan)
    	- Converted from old map_rgb and map_cmyk to new encode_color
    routines. (gdevbit.c [1.6]: 2002/11/13 20:24:12 dan)
    	- Define a decode_color proc for the cmyk devices.
    (gdevcdj.c [1.13]: 2002/11/13 23:33:05 dan)
    	- Convert old map_color_rgb routines to decode_color routines for
    the stcolor device. Change required due to device API change.
    (gdevstc.c [1.9]: 2002/11/14 20:48:47 dan)

    Correct some display device map_color_rgb functions, needed for
    anti-aliasing. (gdevdsp.c [1.13]: 2002/11/13 07:05:43 ghostgum)

    Recorrect display device 4-bit native mode after a correction was reversed
    by DeviceN. (gdevdsp.c [1.14]: 2002/11/13 07:24:03 ghostgum)

    Remove duplicate call to GlobalLock in Windows printer device.
    (gdevwpr2.c [1.14]: 2002/11/16 22:16:49 ghostgum)

## PDF writer

    Fixes problems:
    	- Fix (pdfwrite) : Implement a special check for CMaps which appear
    to be identity, and replace them with a standard CMap name. Source Forge bug
    "[ 615994 ] CMAP is corrupted". (gdevpdtc.c [1.11]: 2002/11/02 19:16:44
    igor)
    	- Fix (pdfwrite) : Removing gx_device_pdf_s::random_offset because
    it is not longer in use. (gdevpdfx.h [1.55], gdevpdtb.c [1.10]: 2002/11/17
    22:18:15 igor)
    	- Fix (pdfwrite) : Removing gx_device_pdf_s::random_offset because
    it is not longer in use. (gdevpdf.c [1.56]: 2002/11/17 22:27:53 igor)
    	- Fix (pdfwrite) : Improving the condition about skipping paths
    outside the clipping path. SourceForge bug "[ 628542 ] (pdfwrite) wrong
    gs5.98-dragon.pdf". (gdevpdfd.c [1.21]: 2002/11/18 02:53:44 igor)
    	- Fix (pdfwrite) : (1) FontMatrix.ty was ignored while computing
    glyph positions. (2) Working around AR4,5 bug which ignores FontMatrix.ty .
    SourceForge bug "[ 629961 ] (PDF interpeter) 'Ghost' text appears again".
    (gdevpdtb.c [1.11], gdevpdtt.c [1.23]: 2002/11/18 03:05:22 igor)
    	- Fix (pdfwrite) : Skipping text outside clip path. SourceForge bug
    "[ 608520 ] PDFWrite failed for PS File". (gdevpdfd.c [1.22],
    gdevpdte.c [1.20]: 2002/11/18 14:29:54 igor)

## PDF Interpreter

    Fixes problems:
    	- Fix for #609488 Problems in DeviceN test file. This resolves
    problems that can occur if the transfer function are dependent upon the
    halftone. (Which is true for the default hi res transfer function.) We were
    getting variable (unpredictable) results due to the undefined ordering in
    enumerating graphic state dictionaries via the 'forall' operator.
    (lib/pdf_draw.ps [1.62]: 2002/11/05 00:48:01 dan)
    	- resourcefont procedure didn't handle correctly font descriptor
    without font stream. Bug #633714 (lib/pdf_font.ps [1.51]: 2002/11/14
    21:22:22 alexcher)

    Move code from pdfshowpage to pdfshowpage_finish for the benefit of GSview
    which calls pdfshowpage_init and pdfshowpage_finish, but not
    pdfshowpage_setpage. (lib/pdf_main.ps [1.63]: 2002/11/05 20:56:02 ghostgum)

## Interpreter

    Fixes problems:
    	- Eliminate possible negative discontinuity in default hi resolution
    transfer function. (lib/gs_init.ps [1.71]: 2002/11/05 00:30:59 dan)
    	- The 'bind def' was dropped from the previous commit: Fix:
    Eliminate possible negative discontinuity in default hi resolution transfer
    function. (lib/gs_init.ps [1.72]: 2002/11/05 08:02:17 dan)
    	- When processing an EPS file, remove any left over items on the
    operand and dictionary stacks. (lib/gs_epsf.ps [1.8]: 2002/11/12 20:31:30
    ghostgum)
    	- Use immediate evaluation for forcesetcolorspace operator because
    its definition goes out of scope when bind is delayed or disabled. Bug
    #635747 (lib/gs_devn.ps [1.3], lib/gs_indxd.ps [1.2], lib/gs_patrn.ps [1.2],
    lib/gs_sepr.ps [1.2]: 2002/11/13 20:23:10 alexcher)
    	- Skip /ColorValues processing for devices where it is not defined
    (typically grayscale devices). Fixes SF bug #636213. (lib/gs_dps.ps [1.8]:
    2002/11/14 17:24:00 raph)
    	- Restore silent clip of sethsbcolor values to range [0..1].
    (lib/gs_cspace.ps [1.4]: 2002/11/15 18:10:24 raph)
    	- Replace the previous gp_file_name_is_absolute with
    gp_patshtring_not_bare which generally has the same sense, but is more
    consistently implemented on platforms and indicates whether or not a
    pathstring can be prefixed by a directory and the path_separator string.
    Also, fix check_file_permissions to handle the 'bare' pathstring case when
    the current directory is one of the permitted paths. Fixes SourceForge bug
    #637751. (lib/gs_fapi.ps [1.17], zfile.c [1.23]: 2002/11/17 22:50:32 ray)
    	- check_file_permissions did not handle the case where no path
    separator is needed after the current_directory_name. PostScript code in
    .locksafe (in gs_init.ps) was already correct. Problem would happen on Mac
    & VMS. (zfile.c [1.24]: 2002/11/18 17:17:20 ray)
    	- Correcting mixed DOS/UNIX line ends introduced in the previous
    version. (zcolor.c [1.14]: 2002/11/18 19:14:57 alexcher)
    	- FrameMaker produces PS file that assumes that the presence of
    /pdfmark in systemdict implies availability of /currentdistillerparams. The
    fix hides /pdfmark for all devices except pdfwrite following
    set/currentdistillerparams pattern. Bug #638982 (lib/gs_pdfwr.ps [1.21]:
    2002/11/18 19:36:57 alexcher)

    Modified the setdevice procedure to reset the current halftone (if possible)
    when changing devices. This is necessary in the DeviceN code because the
    number of device halftone components must be the same as the number of
    device color model components. It is also generally a good idea.
    (lib/gs_init.ps [1.70]: 2002/11/05 00:10:37 dan)

    Post-release cleanup for 7.32: increment version number to 7.33.
    (lib/gs_init.ps [1.73]: 2002/11/05 08:31:56 raph)

    Correct -dEPSFitPage when the device has non-zero margins.
    (lib/gs_epsf.ps [1.7]: 2002/11/07 07:14:28 ghostgum)

    Correct some display device map_color_rgb functions, needed for
    anti-aliasing. (gdevdsp.h [1.6]: 2002/11/13 07:05:43 ghostgum)

    Prevent access to .forceput and friends. Patch by Alex Cherepanov and
    Russell Lang. (lib/gs_diskn.ps [1.4], lib/gs_epsf.ps [1.9],
    lib/gs_fonts.ps [1.23], lib/gs_res.ps [1.26], lib/gs_resmp.ps [1.6],
    lib/gs_type1.ps [1.13]: 2002/11/18 20:23:18 ghostgum)

## Streams

    Fixes problems:
    	- Make init method for ASCII85Encode return 0. Fixes SF #634519.
    (sa85x.h [1.6]: 2002/11/13 08:23:13 raph)

## Library

    Fixes problems:
    	- param_check_string now checks is_valid before trying to calculate
    the length of the string in question. We now handle a null
    color_info.cm_name in all cases. (gsdparam.c [1.12]: 2002/11/02 17:22:29
    giles)
    	- Fix (pdfwrite) : Implement a special check for CMaps which appear
    to be identity, and replace them with a standard CMap name. Source Forge bug
    "[ 615994 ] CMAP is corrupted". (gdevpsf.h [1.21], gdevpsfm.c [1.11]:
    2002/11/02 19:16:44 igor)
    	- Fixing the "members" logic in gs_type1_glyph_info. Arithmetic
    operations were erroneously used instead logic ones, sometimes causing a
    request of undefined features. Source Forge bug "[ 629116 ] Bad font in
    re-distilled PDF". (gxtype1.c [1.20]: 2002/11/02 20:07:46 igor)
    	- These are a set of fixes required to make the 2 bit memory device
    functional. They are being lumped together since they are all required. The
    fix in gdevm2.c was found by customer #760 and is reported as bug #600281
    mem_mapped2_copy_mono() incorrect. (gdevm2.c [1.5], gxcht.c [1.11]:
    2002/11/05 01:03:14 dan)
    	- Make some debug warning messages only occur for DEBUG build. The
    most common offender seen was "No encode_color proc defined for device."
    (gxcmap.c [1.12]: 2002/11/05 19:13:52 dan)
    	- Define color encode/decode procedures for the nullpage and null
    devices. This eliminates a "No encode color proc defined" message for these
    devices. (gdevnfwd.c [1.8]: 2002/11/13 06:00:29 dan)
    	- Change the substitution logic for the decode_color procedure. This
    change gives preference to the map_color_rgb proc (if it exists) and the
    device is an RGB device. The previous logic gave preference to
    gx_default_decode_color if the device was linear and separable.
    (gdevdflt.c [1.10]: 2002/11/13 19:31:28 dan)
    	- Fix uninitialized memory read; gx_set_device_color_1(pgs) depends
    on the value of pg->in_cachedevice, so move up initialization of the
    latter. (gsstate.c [1.19]: 2002/11/13 21:51:34 raph)
    	- Replace the previous gp_file_name_is_absolute with
    gp_patshtring_not_bare which generally has the same sense, but is more
    consistently implemented on platforms and indicates whether or not a
    pathstring can be prefixed by a directory and the path_separator string.
    Also, fix check_file_permissions to handle the 'bare' pathstring case when
    the current directory is one of the permitted paths. Fixes SourceForge bug
    #637751. (gp.h [1.13], gp_dosfs.c [1.6], gp_unifn.c [1.6],
    gp_unifs.c [1.10]: 2002/11/17 22:50:32 ray)

    Post-release cleanup for 7.32: increment version number to 7.33.
    (gscdef.c [1.30]: 2002/11/05 08:31:56 raph)

    Suppress the "No encode color proc" warning for the "null" device (a
    forwarding device) where it is expected and acceptable. (gxcmap.c [1.13]:
    2002/11/06 23:11:17 ray)

    First commit of 7.33 beta release: update dates and version numbers, edits
    to News.htm. (gscdef.c [1.31]: 2002/11/18 21:41:51 raph)

## Other

    Fixes problems:
    	- remove the unused SYSTIME_H from the mac headers. Prefer "time_.h"
    to <sys/time.h>. Although the Metroworks Standard Library doesn't have
    a sys/time.h, keep the definition of HAVE_SYS_TIME_H for now to avoid a

# Version 7.32 (2002-11-02)

This is the second beta release in preparation for 8.0. The most notable new feature is Well Tempered Screening, which now works for angles of 0 and 45 degrees as well.

To test WTS, set the UseWTS user parameter:

>     << /UseWTS true >> setuserparams

Also make sure you're not in a banding mode (setting `-dMaxBitmap=500000000` should work), and that your halftone dictionaries set /AccurateScreens.

A fair number of bugfixes have also made it into this release, including a fix for the slow rendering of PDF's in GhostView-derived viewers.

The following SourceForge bug numbers were open at the time of this release: 405342, 407342, 414947, 414985, 446344, 458261, 458775, 458780, 459647, 465936, 484752, 484753, 487953, 493348, 505429, 510808, 526099, 526491, 530011, 535366, 535752, 535836, 538033, 539239, 546823, 554076, 558151, 558435, 563287, 569573, 570772, 573744, 578838, 578865, 584990, 592160, 592837, 592841, 592925, 592930, 595760, 596009, 598014, 600281, 600288, 601255, 601336, 601694, 602995, 603934, 605830, 607425, 607850, 608520, 609488, 610356, 610478, 610727, 611694, 611701, 611727, 611898, 612801, 614298, 615165, 615994, 616970, 616976, 617077, 617523, 621243, 621246, 623122, 623292, 623989, 624515, 625085, 626059, 626295, 626358, 626419, 626464, 627545, 628110, 628542, 628557, 629116, 629335, 629961, 631180, 631974.

    When ghostscript is given a PDF file on standard input, copy it to a
    temporary file before processing. Prior to version 7, ghostscript could read
    PDF from standard input redirected from a file, but not from a pipe.
    Standard input was changed in version 7 to use callouts, which prevented PDF
    reading from standard input. Fixes SourceForge bug #583413, /ioerror with gs

## Procedures

    Fixes problems:
    	- adds a missing header to gxshade for indexed color routines.
    (lib.mak [1.103]: 2002/10/22 13:31:37 giles)
    	- update the ECHOGS_MAK dependency to ECHOGS_XE. (devs.mak [1.80],
    int.mak [1.86], lib.mak [1.105]: 2002/10/22 18:38:00 giles)
    	- correct some dependencies against the include lists in the
    relevent C files. Also reorder them to facilitate easer checking next time.
    Closes SourceForge bug #607819. (int.mak [1.89], lib.mak [1.108]: 2002/10/28
    19:17:19 giles)
    	- install cidfmap on unix. (unixinst.mak [1.27]: 2002/10/28 19:27:06
    giles)
    	- install the example FAPI configuration files by default. Ideally
    this would be dependent of enabling the fapi feature in the build.
    (unixinst.mak [1.28]: 2002/10/28 19:43:42 giles)
    	- provided a meaningful error message when an immediately evaluated
    name can not be found. Fixes SourceForge bug #543185, Confusing diagnostics
    for //undefined. (int.mak [1.91]: 2002/10/29 09:57:53 ghostgum)
    	- also install the character translation FAPI config file.
    (unixinst.mak [1.29]: 2002/10/31 16:01:12 giles)
    	- Fiddles with makefile parameter quoting so that "make pg" runs
    again. (unix-end.mak [1.5]: 2002/11/02 05:51:00 raph)

    Remove the gcc version check from the macosx makefile. That platform is
    unlikely to be running the version in question. (macosx.mak [1.14]:
    2002/10/18 13:17:07 giles)

    Use 'gcc2' as the C compiler with the macosx makefile, working around a bug
    in Apple's gcc3 (the default cc). This won't work on pre-10.2 developer
    tools, but users are less likely to encounter that now. (macosx.mak [1.15]:
    2002/10/18 15:48:26 giles)

    Corrects various include dependency problems. Closes SourceForge Bug
    #604884. (devs.mak [1.79], int.mak [1.85], lib.mak [1.104]: 2002/10/22
    16:47:30 giles)

    Remove pdfwrite testing module zfctest and associated source.
    (int.mak [1.87]: 2002/10/22 18:42:32 giles)

    Add real 'make distclean' and 'make maintainer-clean' targets. These are no
    longer general no-ops but are the responsibility of the platform-specific
    makefiles. The autoconf build now removes its generated files from the
    top-level directory when requested. (gs.mak [1.18], unix-gcc.mak [1.38],
    unixansi.mak [1.26]: 2002/10/24 12:57:57 giles)

    Rename the makefile variable UFST_CFLAG to the more conventional
    UFST_CFLAGS. (int.mak [1.88], lib.mak [1.106], msvc32.mak [1.35]: 2002/10/24
    16:07:20 giles)

    Removes the alpha storage device. This code is obsolete and has been unused
    for some time. Closes SourceForge bug #592164. (lib.mak [1.107]: 2002/10/25
    12:14:54 giles)

    Bump version after the 7.31 release. (version.mak [1.54]: 2002/10/28
    20:11:08 giles)

    Remove some interpreter references from the graphics library. Partial fix
    for SourceForge bug #542848, "library #includes interpreter headers".
    (lib.mak [1.109], msvclib.mak [1.21], msvctail.mak [1.9], pcwin.mak [1.5]:
    2002/10/29 09:22:29 ghostgum)

    Changes to Windows and OS/2 files to allow ghostscript to compile with the
    graphics library and interpreter in separate source directories. Partial fix
    for SourceForge bug #542848, "library #includes interpreter headers".
    (bcwin32.mak [1.22], int.mak [1.90], msvc32.mak [1.36], os2.mak [1.28],
    watcw32.mak [1.19], winint.mak [1.16]: 2002/10/29 09:44:40 ghostgum)

    Encapsulate EPS files to make sure that at least one page is printed. Add
    command line options -dNOEPS, -dEPSCrop and -dEPSFitPage for customizing
    handling of EPS files. Warn if EPS bounding box does not fit in clipping
    box. Enable EPS and DOS EPS processing for several platforms.

    2002/10/31 09:22:13 ghostgum)

    Remove the obsolete mswindll and mswinprn devices from the standard Windows
    build. (bcwin32.mak [1.24], msvc32.mak [1.38], watcw32.mak [1.21]:
    2002/10/31 10:11:03 ghostgum)

    Reinstate the mswindll device because removing it also requires modifying
    the exports in gsdll32.def. (bcwin32.mak [1.25], msvc32.mak [1.39],
    watcw32.mak [1.22]: 2002/10/31 10:51:29 ghostgum)

    Add a utility that draws glyphs on top of the character box defined in the
    given AFM. Goes throuh each glyph in the AFM. (toolbin/drawafm.ps [1.1]:
    2002/10/31 18:08:49 ray)

    Module gslib removed from the library archive. Further fix for [ 538311 ]
    files missing from library archive. (ugcclib.mak [1.22]: 2002/11/02 04:28:15
    ghostgum)

    	- Apply SubFileDecode filter during stream resolution to unfiltered
    streams (except inline images) to prevent merging of the last token of the
    stream with endstream operator. (jointly with Ray Johnston) Bug #628097 from
    customer #1 (lib/pdf_base.ps [1.30], lib/pdf_draw.ps [1.61]: 2002/11/01
    20:00:12 alexcher)

    Moved the redefinition of the DefaultGray, DefaultRGB, and DefaultCMYK
    instances of the ColorSpace resource category to the pdfopen procedure, as
    opposed to the runpdf procedure. This avoids unintended color space
    substitution when using utilities such as gv, gsview, etc., which do not
    invoke the runpdf procedure. Thanks to both Raph Levien and Russell Lang for
    suggesting this modification. (lib/pdf_main.ps [1.58]: 2002/10/17 21:33:03
    dan)

    Moved the invocation of pdfshowpage_setcspacesub from pdfshowpage to
    pdfshowpage_finish. This is done to accommodate gsview, which does not
    invoke pdfshowpage. Thanks to Russell Lang for pointing this out.
    (lib/pdf_main.ps [1.59]: 2002/10/18 17:31:26 dan)

    This is a fix to handle the "slow rendering for PDF files with color space
    substitution" ("-dUseCIEColor") problem. The code for the patches is the
    same as in yesterday's message; some comments have been added, and some of
    the earlier comments made more clear (we hope). Modified Files:
    lib/gs_cspace.ps Modified the _setcolorspace procedure to ignore redundant
    settings of the current color space for PDF files, even if color space
    substitution is in effect. lib/pdf_main.ps Modified pdfshowpage_setcspacesub
    to "transition" the current color space if color space substitution is in
    effect and the current color space is a device-dependent color space.
    (lib/pdf_main.ps [1.60]: 2002/10/24 04:13:50 dan)

    Change some pdfformaterror messages to "Warning" to avoid user confusion and
    alleviate concern. Also this should help bug reports to be less misleading.

    When ghostscript is given a PDF file on standard input, copy it to a
    temporary file before processing. Prior to version 7, ghostscript could read
    PDF from standard input redirected from a file, but not from a pipe.
    Standard input was changed in version 7 to use callouts, which prevented PDF
    reading from standard input. Fixes SourceForge bug #583413, /ioerror with gs

## Interpreter

    Fixes problems:
    	- A typo in .locksafe procedure left 2 boolean parameters on the
    stack causing PS errors in some files produced by "dvips(k) 5.86" that
    depend on empty initial operand stack. Bug #626437 (lib/gs_init.ps [1.67]:
    2002/10/24 20:37:29 alexcher)
    	- currentcolorspace didn't check whether the current device is a
    cache device and always returned the value set by setcolorspace in the
    current graphic state. The fix returns [/DeviceGray] as the current color
    space in cache device. Bug #627169 (zcolor.c [1.13]: 2002/10/24 22:48:41

    	- provided a meaningful error message when an immediately evaluated

    	- Adobe interpreters accept numbers as values of /C0 or /C1
    parameters of Type 2 function contrary to PLRM. Adobe has also published
    smooth shading examples that use this feature. So GS has to follow. Bug

    	- Redefine .runstdin with one bound to EPSF 'run' operator so that
    EPS files are handled correctly from %stdin. Code for skipping DOS EPS
    header now uses the EPS encapsulating run, instead of directly calling
    .runexec. (lib/gs_epsf.ps [1.6]: 2002/11/01 23:41:18 ghostgum)
    	- Provide a meaningful error message when an immediately evaluated

    (dwmain.c [1.12]: 2002/10/29 09:44:40 ghostgum)

    Encapsulate EPS files to make sure that at least one page is printed. Add

    Proposed log message: According to PLRM 3rd ed, p. 264 "indexed color space
    is not allowed in any shading whose color values are generated by a
    function; this applies to any shading dictionary that contains a Function
    entry." Adobe interpreters follow PLRM in this respect and we follow them.
    Bug #591768 (zshade.c [1.14]: 2002/10/31 16:19:48 alexcher)

    Adds UseWTS user parameter to enable WTS, rather than a compile-time #define
    USE_WTS as before. Also, WTS is now only enabled when AccurateScreens is
    selected. (zusparam.c [1.8]: 2002/11/02 07:33:48 raph)

## Streams

    Remove some interpreter references from the graphics library. Partial fix
    for SourceForge bug #542848, "library #includes interpreter headers".
    (sarc4.c [1.8]: 2002/10/29 09:22:29 ghostgum)

## Library

    Fixes problems:
    	- adds a missing header to gxshade for indexed color routines.
    (gxshade.c [1.15]: 2002/10/22 13:31:37 giles)
    	- On gcc 2.95.4 for Alpha all structures are padded to 8 byte
    boundary but sizeof(bool) == 4. First member of the subclass is restored
    because it is overwritten by padding data. Bug #613909 (gximage3.c [1.11]:
    2002/10/25 00:27:10 alexcher)
    	- correct some dependencies against the include lists in the
    relevent C files. Also reorder them to facilitate easer checking next time.
    Closes SourceForge bug #607819. (gscolor2.c [1.14], gxclrast.c [1.26]:

    	- For Type9 fonts (CIDFontType 0 with Type 1 or Type 2 leaf fonts),
    the leaf's FontMatrix was being ignored. Catch the change of leaf font index
    in select_descendant_font, and for Type9 (ft_CID_encrypted) concatenate the

    from Forrest Cahoon, improved. (gxstroke.c [1.7]: 2002/10/31 09:00:28 igor)
    	- Fix incorrect calculation of the clipping path around the pattern
    tile. Old code used bounding box of the tile in device coordinate system as
    a clippin path. When the tile was not aligned with device coordinates the
    box extended beyond the tile parallelogram causing incorrect rendering of a
    pattern depending on clipping path. New code draws correct clipping path by
    taking advantage of high level functions. Also gs_bbox_transform() was moved
    out of compute_inst_matrix() to improve readability. Bug #595378
    (gsptype1.c [1.13]: 2002/10/31 16:34:01 alexcher)
    	- Default allocator added to the stable allocator because it is used
    in s_zlib_alloc() when the clist is stored in memory. According to
    doc/Develop.htm: "Every allocator has an associated stable allocator, which
    tags pointers with the same VM space number but which is not subject to save
    and restore. System VM is intrinsically stable (its associated stable
    allocator is the same allocator)" Bug #530588 (gsmalloc.c [1.11]: 2002/10/31

## Other

    Add real 'make distclean' and 'make maintainer-clean' targets. These are no
    longer general no-ops but are the responsibility of the platform-specific
    makefiles. The autoconf build now removes its generated files from the
    top-level directory when requested. (Makefile.in [1.18]: 2002/10/24 12:57:57
    giles)

    Remove configure.ac only on maintainer-clean. It's more transparent to
    distribute this file as well along with configure. (Makefile.in [1.19]:
    2002/10/24 13:25:01 giles)

# Version 7.31 (2002-10-17)

This is the first beta release in preparation for 8.0. A great many bugs have been fixed since the 7.30 alpha release, and it should be stable for most users. Two features planned for 8.0 are not yet fully functional, however: subpixel positioning of antialiased text, and Well Tempered Screening (the latter can be enabled for experimentation, but does not work for 0 and 45 degree angles).

The following SourceForge bug numbers were open at the time of the last release: 405342, 407342, 414947, 414985, 434277, 446344, 446672, 458261, 458775, 458780, 459647, 465720, 465936, 468762, 484752, 484753, 485510, 487953, 493348, 505429, 508081, 509646, 510808, 513905, 517349, 526099, 526491, 528647, 530011, 530588, 535366, 535752, 535836, 538033, 538428, 539239, 542848, 543185, 546823, 552989, 554076, 558151, 558435, 563287, 567421, 567773, 569573, 570772, 572119, 573744, 576591, 576591, 578838, 578865, 583413, 584990, 591768, 592160, 592164, 592837, 592841, 592925, 592930, 594582, 595375, 595378, 595760, 596009, 598014, 600281, 600288, 601255, 601336, 601694, 602739, 602995, 603577, 603689, 603934, 604884, 604886, 605830, 607425, 607819, 607850, 608520, 609488, 609494, 609809, 610040, 610356, 610359, 610478, 610727, 611463, 611694, 611701, 611727, 611898, 612801, 613165, 613909, 613909, 614298, 614299, 615165, 615620, 615994, 616970, 616976, 617077, 617523, 620420, 620865, 620968, 621243, 621246, 621293, 623122, 623292, 623989, 624082, 624168, 624493, 624515.

A few regressions remain. See the archives of the regression report for more details. Another known issue is slow rendering of PDF's from GSView and Ghostview family viewers.

### Incompatible changes

The `-dDOPS` flag (to enable DoPS processing) is now disabled by default, as it is a more reasonable default. Thus, any files which depend on DoPS will now break unless this flag is set.

## Documentation

    Fixes problems:
    	- Mentions the autoconf build method in the installation
    documentation. Inspired by a user report of having looked there first rather
    than at Make.htm; an understandible choice based on linux packaging
    conventions. (doc/Install.htm [1.35]: 2002/09/16 21:15:39 giles)
    	- Keep pagedevice and device views of .LockSafetyParams correct even
    after a 'restore' is used to unlock. The dictionary fed to the setpagedevice
    operator is allocated in the same VM space as currentpagedevice to avoid
    invalidaccess problems. Fixed SF #580029 and does not revert to the
    incorrect behaviour of bug #516379. (doc/Language.htm [1.53]: 2002/09/18

## Procedures

    Fixes problems:
    	- Fix (pdfwrite): Virtual function same_font cannot work properly if
    arguments have different representation (particularly for comparing an
    original font with its stable copy). Due to it pdf_font_resource_t::Widths
    mixed widths taken from fonts variations with different metrics. Entirely
    changing the logics of creating font resources with new function
    gs_copied_can_copy_glyphs. Source Forge bugs : #596394 (pdfwrite) Wrong
    glyph width (093-01.ps), #567604 missing characters with -c save pop #596284
    font spacing/ragged edge on text column (devs.mak [1.73], lib.mak [1.96]:
    2002/09/08 20:20:12 igor)
    	- Fix (pdfwrite) : Completely removing the generation of "space
    chars", because they can overflow Encoding. (devs.mak [1.74]: 2002/09/15
    13:21:09 igor)
    	- Fix (pdfwrite) : Completely removing the old PDF text code.
    (devs.mak [1.75]: 2002/09/15 14:11:51 igor)
    	- On case-insensitive file systems, sometimes PDF file detection
    wasn't working. (toolbin/tests/gstestgs.py [1.14]: 2002/09/18 19:17:40 jack)
    	- Typo in run_nightly. (toolbin/tests/run_nightly [1.7]: 2002/09/19
    19:51:20 jack)
    	- In dots mode, the DIFFER result had a spurious newline.
    (toolbin/tests/gstestutils.py [1.5]: 2002/09/23 15:56:31 jack)
    	- Fix : Providing a virtual path interface for computing glyph bbox
    without allocating path segments. SourceForge bug "[ 605200 ] pdf_close
    generates many path segments". (lib.mak [1.100]: 2002/09/23 16:38:28 igor)
    	- Fix previous commit (marginal python skills)
    (toolbin/tests/run_nightly [1.9]: 2002/09/26 16:28:15 ray)
    	- Fix syntax errors and use actual paths for run_regression and
    testdiff (toolbin/tests/run_nightly [1.11]: 2002/09/29 22:33:17 ray)
    	- removes duplicate definition of gscspace_h. (lib.mak [1.102]:
    2002/10/10 20:21:38 giles)
    	- Remove psdrgb.dev and psdcmyk.dev from the MSVC makefile (these
    crept in by mistake). (msvc32.mak [1.33]: 2002/10/11 15:39:35 ray)
    	- remove the remainder of the gcc version check hack through the aux
    dependency. This was missed in initial commit of that changed and prevented
    normal running of the mcp-generation makefile. (macos-mcp.mak [1.10]:
    2002/10/17 16:12:36 giles)

    Update documentation to remove some confusion between Borland C++ 5 and
    Borland C++Builder 5. (bcwin32.mak [1.21]: 2002/09/09 12:05:59 ghostgum)

      src/int.mak
      src/lib.mak
        Updated various dependency lists.
    (int.mak [1.83], lib.mak [1.97]: 2002/09/10 22:16:07 dan; checkin for Jan)

    Bump version numbers after 7.30 release. (version.mak [1.52]: 2002/09/12
    09:52:20 giles)

      src/lib.mak
        Updated the dependency list for gxclrast.$(OBJ).
    (lib.mak [1.98]: 2002/09/13 22:21:22 dan; checkin for Jan)

    Implements daily results databases for regression results as well as a new
    tool 'testdiff' to view the difference between two such databases. Also
    updates the nightly report output to include a new section of just that
    day's new regressions. (toolbin/tests/gscheck_pdfwrite.py [1.5],

    Revive the fuzzy pdfwrite compare test.
    (toolbin/tests/gscheck_fuzzypdf.py [1.1]: 2002/09/23 16:26:15 jack)

    Put in log files for the preparation steps: cvs update, make and install.
    The cvs logs are cumulative (they can be truncated manually if desired).
    These changes were in the actual running scripts until 9/18 when an update
    overwrote these changes that were being tested, but were never committed.
    (toolbin/tests/run_nightly [1.8]: 2002/09/26 16:18:42 ray)

    The last fixup -- more bad python. (toolbin/tests/run_nightly [1.10]:
    2002/09/26 16:33:01 ray)

    Move the callback routine, which is used to translate a gs_separation_name
    into a string pointer and a length, from the graphics state into the device
    color structure. This is being done to make it available to the pdfwrite
    device when handling DeviceN or Separation color spaces. (int.mak [1.84]:
    2002/10/04 23:43:38 dan)

      src/devs.mak
        Updated dependency list for gdevscf.$(OBJ).
      src/lib.mak
        Updated various dependency lists.
    (devs.mak [1.76], lib.mak [1.101]: 2002/10/08 00:49:48 dan; checkin
    for Jan)

    Prune the dead 'begin' makefile target. This was supposedly removed in
    release 5.20. (gs.mak [1.16]: 2002/10/09 22:13:17 giles)

    Remove remaining references to ansi2knr.c. We no longer support building
    ghostscript with it, but the remaining dead code causes confusion for some
    users. Inspired by Sourceforge bug #618048. Removes references to the no
    longer supported ansi2knr.c. (dvx-gcc.mak [1.20], dvx-tail.mak [1.8],

    Change the default on the MSVC build to use 64 bit gx_color_index values.
    (msvc32.mak [1.32]: 2002/10/11 00:14:23 dan)

    Adds PhotoShop (psdcmyk and psdrgb) devices. (devs.mak [1.77],
    msvc32.mak [1.34], unix-gcc.mak [1.37]: 2002/10/12 11:47:11 jeong)

    This is some clean up on the DeviceN devices: XCF, PSD, and spot devices. 1.
    Ensuring that the process color model name is correct. 2. removing support
    of SeparationColorNames from additive devices. 3. Finish removal of variable
    bits per components (GrayValues) from the devices. None of them had any form
    of correct support for this feature. (devs.mak [1.78]: 2002/10/16 07:43:46
    dan)

    Removes the obsolete 'hpijs' driver. This has been superceeded by the ijs
    driver interface both in Ghostscript and the hpijs collection of printer
    drivers. (contrib.mak [1.28]: 2002/10/16 23:26:33 giles)

    First documentation commit for 7.31 release: edits to News.htm, version and
    date updates, minor patches to Develop.htm and Deprecated.htm.
    (version.mak [1.53]: 2002/10/17 06:37:29 raph)

## Utilities

    Fixes problems:
    	- code cleanup in macos platform specific routines. (gp_mac.c [1.9]:
    2002/09/17 00:09:26 giles)
    	- the console stubs are no longer necessary for the macos build.
    (macgenmcpxml.sh [1.4]: 2002/09/17 00:57:38 giles)
    	- remove some compiler options that generated spurious warnings.
    (macgenmcpxml.sh [1.5]: 2002/09/26 19:50:12 giles)

    Apply casts to remove lots of warnings from MSVC 6. Update some Windows
    color mapping functions for DeviceN. Change order of arguments for the
    gs_pdf14_device_filter_push function and the calls to the device filter push
    procedure to match the prototype. (gp_mswin.c [1.13], gp_ntfs.c [1.10],
    gp_win32.c [1.5]: 2002/10/07 08:28:56 ghostgum)

## Drivers

    Fixes problems:
    	- Introduces "backwards compatible" encode_color routine for
    grayscale devices which supply map_rgb_color but not encode_color. Fixes
    gray modes in pdfwrite and ijs devices, among others. (gdevbmpc.c [1.7],
    gdevijs.c [1.5]: 2002/10/17 06:09:33 raph)

    Change bmpgray device to use 8-bit 1 component instead of instead of 8-bit 3
    components. (gdevbmp.c [1.7]: 2002/09/16 20:35:07 ghostgum)

    Apply casts to remove lots of warnings from MSVC 6. Update some Windows
    color mapping functions for DeviceN. Change order of arguments for the
    gs_pdf14_device_filter_push function and the calls to the device filter push
    procedure to match the prototype. (gdev4693.c [1.7], gdevbj10.c [1.8],

    Attached is a updated version of our code release of 4 October, 2002. As
    before, the primary purpose of this release is to modify the manner in which
    overprint information is passed to the overprint compositor device. This
    resolves some difficulties seen when overprinting is used with the command
    list device. This update incorporates the changes checked in by Dan on
    October 4th. Since Dan's changes to gxcldev.h and gxclrast.c were identical
    to ours, we have removed those two files from this release. Jan Modified
    Files lib/gs_init.ps lib/pdf_draw.ps Change "DONTPS" flag to "DOPS", with
    the logically inverted function: only if DOPS is defined will "PS" XObjects
    be rendered. We believe this is the more appropriate default. lib/gs_dps.ps
    lib/gs_img.ps src/gsdparams.c Modified the deviceinfo and image code to work
    around a potentially improperly set ColorValues parameter. src/devs.mak
    Updated dependency list for gdevscf.$(OBJ). src/gdevdflt.c 1. Added
    initialization of the new color_info.opmode field to
    gx_device_fill_in_procs. 2. In get_decode_color, added special case handling
    for canonical 1-bit CMYK devices (e.g.: pkmraw). Previously the decode_color
    method for this devices would default to gx_default_cmyk_decode_color, which
    performed an CMYK ==> RGB ==> CMYK conversion. This conversion would
    defeat overprinting if gray object was placed on top of a colored region.
    src/gscdevn.c src/gscolor.c src/gscolor2.c src/gscpixel.c src/gscsepr.c
    src/gscspace.c src/gsovrc.c src/gxovrc.h src/gspcolor.c src/gsptype1.c
    src/gsptype2.c src/gsstate.c src/gsstate.h src/gxcmap.c src/gxcspace.h
    src/zcolor.c Modified the overprint code to, when necessary, pass overprint
    mode information when setting the device color. This is necessary to
    properly handle overprint mode when using the command list device. NB: This
    change alters the meaning of the "effective_overprint_mode" field in the
    imager state. src/gxdevcli.h Added the opmode and process_comps fields to
    the gx_device_color_info structure. These are required by the new code that
    passes overprint mode information when the device color is set.
    src/gsdfilt.h Changed the prototype for the push method in the
    gs_device_filter structure to match the actual implementation and usage of
    this method (the third and fourth operands were reversed). src/gsimage.c
    Modified gx_image_cleanup to check if penum->info field is null before
    calling gx_image_end. This avoids a crash associated that can occur if an
    image has zero height or width, as the image enumeration data structure will
    have been released in such cases before gs_image_cleanup is called.
    src/lib.mak Updated various dependency lists. src/gdevdevn.c src/gdevnfwd.c
    src/gdevpdte.c src/gdevxcf.c src/gscrdp.c src/gsdfilt.c src/gsht.c
    src/gsht1.c src/gswts.c src/gzht.h src/ialloc.c src/imain.c src/iscanbin.c
    zfapi.c Installed some minor changes to quiet compiler warnings.
    (gdevdevn.c [1.2], gdevxcf.c [1.3]: 2002/10/08 00:49:48 dan)

    Adds DeviceCMY (-dMode=1) process color model to permute device.
    (gdevperm.c [1.2]: 2002/10/08 16:49:59 raph)

    Add a setup the shift and mask bits in ppm_open. This finishes initializing
    the device as being "linear and separable". This is needed since the various
    pxm devices are using the default color encode routine which needs the
    linear and separable information. (gdevpbm.c [1.10]: 2002/10/09 02:34:11
    dan)

    PhotoShop PSD Driver. (gdevpsd.c [1.1]: 2002/10/12 11:43:21 jeong)

    Removed logic for setting variable number of bits per component. This is not
    supported on the xcf, spotrgb, or spotcmyk devices. (gdevdevn.c [1.3],
    gdevxcf.c [1.4]: 2002/10/15 00:36:57 dan)

    This is some clean up on the DeviceN devices: XCF, PSD, and spot devices. 1.
    Ensuring that the process color model name is correct. 2. removing support
    of SeparationColorNames from additive devices. 3. Finish removal of variable
    bits per components (GrayValues) from the devices. None of them had any form
    of correct support for this feature. (gdevdevn.c [1.4], gdevpsd.c [1.2],

## PDF writer

    Fixes problems:
    	- Fix (pdfwrite): Virtual function same_font cannot work properly if
    arguments have different representation (particularly for comparing an

    	- Correct duplicate definition of pdf_font_cache_elem_t which
    prevented compilation. (gdevpdfx.h [1.52]: 2002/09/09 16:08:19 giles)
    	- Fix (pdfwrite) : Completing the logics of the Widths array
    generation. Now the contents of Widths is taken from embedded font, but
    widths for glyphs placement (Tj) are from original font. (gdevpdte.c [1.12],

    	- Fix (pdfwrite) : (1) gs_glyph_info_t::v was uninitialized if glyph
    metrics is taken from the outline (thanks to Erik Strik for spotting it).
    (2) Improving glyph placement. (3) A minor optimization and improving some
    comments about glyph placament. (gdevpdte.c [1.13], gdevpdtt.c [1.12]:
    2002/09/13 23:43:07 igor)
    	- Fix (pdfwrite) : (1) The previous fix wrongly processed Metrics.
    (2) TJ arguments were computed with accounting Tc taken from a desincronized
    text state. (3) Type 42 missed side bearing. (4) An optimization reduces
    calls to gs_default_glyph_info. Debugged with 0.pdf . (gdevpdts.c [1.13],
    gdevpdtt.c [1.13]: 2002/09/14 02:07:33 igor)
    	- Fix (pdfwrite) : (1) Unwinding the previous change for Tj
    (gdevpdts.c). (2) sync_text_state now checks the ending position of the text
    against the starting position of the text continuation (gdevpdts.c); (3)
    font_orig_scale was erroneusely exchenged for original and copied fonts; (4)
    Enhancing the hack in font_orig_scale with upside_down FontMatrix, (Source
    Forge bug "[ 607480 ] 'Ghost' text appears"). (5) Enhancing
    same_type1_hinting with fonts with nulls in Subrs (gxfcopy.c, test file of
    #607480). Debugged with 0.pdf and 020-01.ps. (gdevpdts.c [1.14],
    gdevpdtt.c [1.14]: 2002/09/14 19:29:30 igor)
    	- Fix (pdfwrite) : Skipping Tj breaks being equal to Tc.
    (gdevpdts.c [1.15]: 2002/09/14 20:27:07 igor)
    	- Fix (pdfwrite) : (1) For better precision changing the internal
    representation of Widths to double, and skipping small noise while writing
    Tj. (2) Widths for Type 3 fonts were not computed (020-01.ps, 031-01.ps).

## PDF Interpreter

    Fixes problems:
    	- Resolve Function parameters (optional as well as required) when
    creating the PostScript Function dictionary for shadings. Fixes SourceForge
    bug #609486. Fixes based on analysis and preliminary fix by Dan Coby.
    (lib/pdf_draw.ps [1.52]: 2002/09/15 20:40:54 ray)
    	- If the CIDCount for a font exceeded 32767, building the
    CIDToGIDMap would exceed the maximum string length. Create an array of two
    strings for this case. Also issue a warning if the CIDToGIDMap stream did
    not contain enough characters for the CIDCount. SourceForge bug #611099 for
    Artifex Customer #350. (lib/pdf_font.ps [1.45]: 2002/09/19 18:10:00 ray)

    DeviceN colorspaces. (lib/pdf_draw.ps [1.53]: 2002/09/26 05:26:32 dan)
    	- Fix to PDF interpreter : 1. Changing the logics of the True Type
    cmap choice to comply with PDF spec. 2. Making the embedded font parser to
    create a PS font independently on font resource options, so that the font
    can associate with the font descriptor. 3. Avoiding the redundant parsing of
    embedded fonts with removing the hack for SF bug "533467 Missing char on
    test2a.pdf (regression)". 4. Removing the hack from buildTrueType because it
    has no effect. 5. Widths and Encoding were ignored for embedded True Type

    The attached code release addresses a number of issues:

      1. Most of the code changes are required to turn off overprint mode when
         processing images, smooth shading fills (shfill operator), or
         when using PatternType 2 (smooth shading) patterns.
    [...]

      lib/gs_img.ps
        Added code to turn off overprint mode for images.

      lib/gs_ll3.ps
        Added code to turn off overprint mode for shfill.

      src/zcolor.c
        Added code to disable overprint mode for PatternType 2 patterns.

    Bump version numbers after 7.30 release. (lib/gs_init.ps [1.63]: 2002/09/12
    09:52:20 giles)

      lib/gs_devn.ps
        Modified the cs_install procedure for DeviceN color spaces to
        support the component name array "[ All ]". The documentation
        indicates that this is not legal ("PDF Reference", 3rd. ed.,
        p. 206), but beginning with Acrobat 5, DeviceN color spaces with
        this component name array are handled in the same manner as
        Separation color spaces with the component name All. The modified
        code detects this component array and converts the operand color
        space to a Separation color space.
    (lib/gs_devn.ps [1.2]: 2002/09/23 01:21:02 dan; checkin for Jan)

    The attached code release fixes a variety of memory handling problems
    discovered by Dan's test with the memory validation enabled.

      2. Several problems noted with files 119-01.ps (panel 119-07) and
         119-28.ps (panel 119-31) were caused by a problem with the memory
         allocator used for the jpeg_compress_data structure used with the
         DCTEncode (JPEG) filter. This filter is used by the PDFwriter, the
         JPEG device drive, and as a filter accessible from PostScript.
         In the first two cases the jpeg_compress_data structure is allocated
         using the normal, gs_ref_memory_t structure. When used from
         PostScript, however, this structure is allocated using the
         gs_memory_default allocator (presumably because the jpeg library
         code is not set up to deal with save/restore).

         The gs_memory_default allocator is not a gs_ref_memory_t allocator,
         so it does not create the hidden obj_header_t structures preceding
         each allocated region. The garbage collector is dependent on these
         headers, hence the pointer enumeration routines in structure
         descriptors must not enumerate any pointers to memory allocated
         by non-gs_ref_memory_t headers.

         This creates a difficult problem for the pointer enumeration
         routine of the stream_DCT_state structure, whose data.compress field
         points to a jpeg_compress_data structure. This routine would have
         to determine which allocator was used for this structure before
         deciding whether or not to "enumerate" the data.compress pointer.
         In principle it has enough information to do this (the jpeg_memory
         field of the structure), but this seems like a overly complicated
         solution. Use of a stable gs_ref_memory_t allocator in place of
         the gs_memory_default allocator seems like a simpler solution.

      src/zfdcte.c
        Modified zDCTE to place the jpeg_compress_data structure into stable
        memory rather than use the gs_memory_default allocator.

    Attached is a updated version of our code release of 4 October, 2002.

    As before, the primary purpose of this release is to modify the manner
    in which overprint information is passed to the overprint compositor
    device.  This resolves some difficulties seen when overprinting is
    used with the command list device.

    This update incorporates the changes checked in by Dan on October 4th.
    Since Dan's changes to gxcldev.h and gxclrast.c were identical to ours,
    we have removed those two files from this release.

    Modified Files

      lib/gs_init.ps
      lib/pdf_draw.ps
        Change "DONTPS" flag to "DOPS", with the logically inverted function:
        only if DOPS is defined will "PS" XObjects be rendered. We believe this
        is the more appropriate default.

      lib/gs_dps.ps
      lib/gs_img.ps
      src/gsdparams.c
        Modified the deviceinfo and image code to work around a potentially
        improperly set ColorValues parameter.

      src/devs.mak
        Updated dependency list for gdevscf.$(OBJ).

      src/gdevdflt.c
        1. Added initialization of the new color_info.opmode field to
           gx_device_fill_in_procs.
        2. In get_decode_color, added special case handling for canonical 1-bit
           CMYK devices (e.g.: pkmraw). Previously the decode_color method for
           this devices would default to gx_default_cmyk_decode_color, which
           performed an CMYK ==> RGB ==> CMYK conversion. This conversion would
           defeat overprinting if gray object was placed on top of a colored
           region.

      src/zcolor.c
        Modified the overprint code to, when necessary, pass overprint mode
        information when setting the device color. This is necessary to properly
        handle overprint mode when using the command list device.

        NB: This change alters the meaning of the "effective_overprint_mode" field
            in the imager state.

      src/ialloc.c
      src/imain.c

    The attached code release addresses a number of issues:

      1. Most of the code changes are required to turn off overprint mode when
         processing images, smooth shading fills (shfill operator), or
         when using PatternType 2 (smooth shading) patterns.

      2. A few other changes were required to correct improper updating of the
         overprint compositor information.

      3. The code has been modified to avoid the crash that was observed for
         the file 86554321.pdf on MSWindows XP systems.

      4. The command list playback code has been modified to handle filling of
         thin lines in a manner consistent with the noband case. This allows
         files such as mspro.pdf to be rendered consistently in the banded and
         noband case.

                                                                    Jan

    Modified Files:

      src/gscolor2.c
        1. Modified gs_setcolorspace to call gs_do_set_overprint rather than
           invoking the color space's set_overprint routine directly. This
           allows pattern color spaces to be handled (somewhat more) correctly.
        2. Modified gs_setcolor to update overprint information. This is
           necessary for pattern color spaces, where the color space to be used
           for overprint purposes may be part of the color.

      src/gscspace.c
        Modified gx_set_overprint_DeviceCMYK to use the effective_overprint_mode
        parameter in the image state (rather than the overprint_mode parameter
        itself). This is part of the change necessary to allow overprint mode to
        be turned off when a PatternType2 pattern is used as the current color.

      src/gsdevice.c
        Modified gs_set_device_no_init to call gs_do_set_overprint rather than
        invoking the color space's set_overprint routine directly.

      src/gsdps1.c
        Modified rectfill to use the effective_overprint_mode parameter in the
        imager state (rather than the overprint_mode parameter).

      src/gsovrc.c
        1. Fixed a bug in overprint_draw_thin_line: the third and fourth
           operands in the call to gx_default_draw_thin_line (the y coordinate
           of the first point and the x-coordinate of the second) were
           in reverse order. This caused random lines to appear on various
           overprint mode tests (e.g.: BEST99-00-Path.fh7.pdf,
           Testform.v1.0.2.pdf).
        2. Fixed typo in comment.
        3. Modified the fill_in_procs procedure to initialize the device color
           model information for the temporary device used in this routine.
           Though the color model information does not affect the output of
           the routine, reasonable values must be provided to avoid problems
           when gx_device_forward_fill_in_procs calls gx_device_fill_in_procs.
           This would cause certain systems to crash with files that involved
           overprint/overprint mode (e.g.: 86554321.pdf on MSWinXP/MSVC systems).
        4. Modified several checks that treated the separable_and_linear flag
           in the device color model information as a boolean to handle this
           parameter as an enumeration instead (since it is an enumeration).

      src/gsptype1.c
        Added gs_pattern1_set_color, the set_color method appropriate for
        PatternType 1 patterns. This method performs overprint updating at
        setcolor time, a requirement for patterns as the "colorspace" to be
        used for overprint purposes is determined (in part) by the current
        "color" (pattern).

      src/gsptype2.c
        Added gs_pattern2_set_color, the set_color method appropriate for
        PatternType 2 patterns.

      src/gsstate.c
        1. Changed the criterion used in gs_grestore_only to determine if the
           overprint compositor must be updated. Restoring the graphic state
           may change the current color, which in the case of patterns may
           change the "colorspace" to be used for overprint purposes. The code
           now properly handles this possibility.
        2. Added the gs_do_set_overprint routine, and modified various other
           routines that directly call the current color space's
           set_overprint method to call this procedure instead. The procedure
           implements the special handling required for pattern color spaces,
           where the current color may need to be considered when determining
           which color model components must be retained.
        3. Added code to initialize the effective_overprint_mode parameter in
           the imager state, and provided two external routines to manipulate
           this parameter. The first routine, gs_disable_effective_overprint_mode,
           sets the effective_overprint_mode parameter to false, irrespective
           of the setting of the overprint_mode parameter. The second,
           gs_reset_effective_overprint_mode, sets the effective_overprint_mode
           parameter to have the same value as the overprint_mode parameter.
           The effective_overprint_mode parameter is used to turn off
           overprint_mode when a PatternType 2 pattern is being used.

      src/gsstate.h
        Added prototypes for gs_do_set_overprint,
        gs_disable_effective_overprint_mode, and
        gs_reset_effective_overprint_mode.

      src/gxccache.c
        Modified gx_image_cached_char to invoke gx_set_dev_color before calling
        (non-standard) device fill_mask methods. This handles several
        situations in which a device color is not set when a cached character
        is to be imaged, in particular for the command list device.

      src/gxclpath.c
        Added a comment to indicate that, though the overprint and
        overprint_mode parameters are passed through the command list, they
        usually have no effect, as overprint is controlled by the compositor
        information that is (also) passed through the command list.

      src/gxclrast.c
        1. Added a comment to indicate that the overprint and overprint mode
           parameters passed through the command list usually have no effect.
        2. Added code to initialize the effective_parameter_mode field in the
           imager state (though this field is usually in-effective).
        3. Initialized the fill_zero_width field of the fill_params structure
           in clist_playback_band to have the same value as in the noband case.
           This parameter was previously always set to false, which led to
           dropped lines for some files (e.g.: mspro.pdf).

      src/gxistate.h
        Added the effective_overprint_mode parameter.

      src/gxpcolor.h
        Added a set_color method to the pattern method vector. This method
        performs any PatternType-specific actions necessary at setcolor
        time. For now, this just updates the overprint compositor as required.

    Bump version numbers after 7.30 release. (gscdef.c [1.26]: 2002/09/12
    09:52:20 giles)

      src/gxccache.c
        1. Fixed numerous problems with compress_alpha_bits and its invocation in
           gx_image_cached_char. The former procedure is called only if anti-
           aliasing (text alpha bits > 1) is called for a color that requires
           halftoning or for a device, such as pbmraw, that does not support the
           copy_alpha method. This happens infrequently, and the code was
           apparently never used.
        2. Moved the invocation of gs_set_dev_color to an earlier location in
           gx_image_cached_char, so that the device color will be set before
           any check is made to see if it is a pure color.

      src/gxclimag.c
        1. Added code in clist_fill_mask to return an error if the mask to be
           filled has depth > 1 and clist_disable_copy_alpha flag is set in the
           disable_mask field. The latter will be the case if the target device
           does not support copy alpha. The command list translates fill_mask
           calls into copy_alpha calls, which drives this requirement. By
           returning an error, the fall-back mechanism included in
           gx_image_cached_char (gxccache.c), which is the only client of the
           fill_mask method, can function properly.
        2. Also modified clist_fill_mask to check that the drawing color is
           pure if depth > 1 and use the default fill_mask method if this is
           not the case. (The copy_alpha call to which the command list code will
           translate the fill_mask works only for pure colors.) In addition, if
           the color is pure, the clist_fill_mask routine will now send commands
           to set color1 as well as transmit the device color; the code in
           clist_playback_band (gxclrast.c) assumes that all "copy_mono" and
           "copy_alpha" commands have set color1.

      src/gxclist.c
        Added code in clist_init_data to set the clist_disable_copy_alpha bit
        in the disable_mask field if the target device does not support the
        copy_alpha method. This must be done in this rather unintuitive location
        because it is impossible to tell if the target device supports copy_alpha
        until it has been made into a memory device (via the create_buf_device
        buffer device method).

      src/gxclist.h
        Defined the clist_disable_copy_alpha bit, which is used in the
        disable_mask field to indicate that the target device does not support
        the copy_alpha method.

      src/gxclrast.c
        Added include of gzht.h, to silence some compiler complaints.

      src/gxclrect.c
        Modified clist_copy_alpha to return an error if clist_disable_copy_alpha
        bit is set in the disable_mask field. This bit indicates that the target
        device does not support the copy_alpha method, so we might as well
        return an error now, while there is a chance the client might be able to
        do something about it.

    The modification changes the way tile depth is encoded in the command
    list as part of the cmd_opv_set_tile_size command.

    Modified files:

      gxcldev.h
        Added the macros cmd_depth_to_code and cmd_code_to_depth. These allow
        encoding/decoding of the color model depth parameter (bits/pixel) in
        such a manner as to support depths up to 120 bits (depths > 15 bits
        must be a multiple of 8).

      gxclbits.c
        Modified cmd_store_tile_params to use the cmd_depth_to_code macro.

    The attached code generalizes the sample_load_* and sample_store_* macros
    in gsbitops.h to handle depths up to 64 bits. In addition to providing
    64 bit versions of these macros, we also added the macros sample_load_any,
    sample_load_next_any, and sample_store_next_any. These macros are intended
    to be used in situations in which any supported depth may be used. All of
    the invocations of the sample_load32, sample_load_next32, etc. macros have
    been changed to invoke the *_any version of these macros instead. In
    addition, a few minor changes have been made to silence compiler warning
    messages.

    Modified files:

      src/gdevalph.c
        Changed invocations of the sample_{load|store}_next32 macro to be
        invocations of sample_{load|store}_next_any instead. Also made various
        changes to allow the code to be compiled with the DeviceN system (the
        file has apparently not been compiled for some time).

      src/gdevdbit.c
        Made a couple of minor changes to silence compiler warning messages.

      src/gdevdgbr.c
        Changed invocations of the sample_{load|store}_next32 macro to be
        invocations of sample_{load|store}_next_any instead.

      src/gdevmpla.c
        Changed invocations of the sample_{load|store}_next32 macro to be
        invocations of sample_{load|store}_next_any instead.

      src/gsbitops.c
        Changed invocations of the sample_{load|store}_next32 macro to be
        invocations of sample_{load|store}_next_any instead. Also made the
        value being read/written be of type gx_color_index rather than
        type bits32.

      src/gsbitops.h
        Added 64-bit versions of the sample_load* and sample_store* macros.
        Also added *_any versions of these macros, to be used in situations
        where any supported color depth may be encountered.

      src/gxcindex.h

    optimization in gx_image_cleanup. This procedure will now always invoke
    gx_image_end, even if the image was not rendered (penum->dev == 0).
    (gsht.c [1.12], gsimage.c [1.9]: 2002/09/23 21:36:31 dan)

    The attached code release fixes a variety of memory handling problems
    discovered by Dan's test with the memory validation enabled.

      1. Most of the problems with the FTS were accounted for by a relatively
         harmless dangling pointer problem for paths. In order to support the
         charpath operator, paths are normally constructed in stable memory
         (not subject to save/restore). However, clipping paths were
         constructed in normal memory. If the clippath operator was used to
         make the clipping path the current path, the top-level
         gx_path_segments would be in stable memory, while the rest of the
         path would be in normal memory. A restore operation could then
         leave dangling pointers.

         This is not normally a problem, because the grestore operation
         associated with the restore would clear the gx_path_segments
         structure. This only works on the graphic state stack, however;
         graphic state objects stored in VM would not be reset.

         This is harmful only in a very obscure case when the charpath operator
         is used on a user-defined font whose BuildGlyph procedure contains
         internal save/restore operators and which builds part of its
         output with the clippath operator. As far as we know, this has
         never occurred in practice.

      2. [...zDCTE stable memory...]

      3. If an overprint compositor was used with a banding device, the code
         in clist_playback_band was not cleaning up this compositor before
         exiting. This caused difficulty with the p2b-100.pdf file. This
         code has been modified to close the target device if this device
         does not match the original target device with which the routine
         was invoked.

      4. For historical reasons, the link between a halftone order and its
         tile cache is a bit peculiar. The order includes a pointer to the
         tile cache, and the tile cache keeps a copy of the order, which
         points to the same levels/bit data structure of the original order.
         Because of these two-way points, the order and its tile cache must
         use the same memory allocator to avoid dangling pointer problems.
         The code patch modifies gx_imager_dev_ht_install (gsht.c) to
         preserve this invariant. The change fixes another problem noted for
         p2b-100.pdf.

    With these changes, we are able to run both the PS3 FTS and the full set
    of pdf regression files using the '-Z@$?' switch with no reported problems.

                                                           Jan

    Modified files:

      src/gspaint.c
      src/gspath.c
        In gs_strokepath and gs_clippath, cause the newly constructed path to
        use the memory allocator of the current path, rather than the memory
        of the current graphic state. This is no longer strictly necessary
        due to other changes that place path substructure completely in
        stable memory (see gxpath.c below).

      src/gxpath.c
        Modify path_allocs_segments, rc_free_path_segments_local,
        gx_path_add_lines_notes, and the path_alloc_segment macro to place
        the entire path substructure (from the gx_path_segments structure
        down) in stable memory. This is necessary to avoid dangling
        pointers, as a list of path segments may be attached to another path,
        parts of which were constructed with a different allocator.

      src/gsht1.c
        Removed obsolete code.

      src/gxclrast.c
        In clist_playback_band, close and discard the target device on
        completion of a band if it is not the same as the target device on
        entry.  This is necessary to remove an overprint compositor that

        In gx_imager_dev_ht_install, copy any halftone orders that were not
        allocated using the same allocator as used by the graphic state. This
        must be done to avoid dangling forward/back pointer between halftone
        orders and the associated tile caches.

    Attached is a updated version of our code release of 4 October, 2002.

    As before, the primary purpose of this release is to modify the manner
    in which overprint information is passed to the overprint compositor
    device.  This resolves some difficulties seen when overprinting is
    used with the command list device.

    This update incorporates the changes checked in by Dan on October 4th.
    Since Dan's changes to gxcldev.h and gxclrast.c were identical to ours,
    we have removed those two files from this release.

                                                           Jan

    Modified Files

      lib/gs_init.ps
      lib/pdf_draw.ps
        Change "DONTPS" flag to "DOPS", with the logically inverted function:
        only if DOPS is defined will "PS" XObjects be rendered. We believe this
        is the more appropriate default.

      lib/gs_dps.ps
      lib/gs_img.ps
      src/gsdparams.c
        Modified the deviceinfo and image code to work around a potentially
        improperly set ColorValues parameter.

      src/devs.mak
        Updated dependency list for gdevscf.$(OBJ).

      src/gdevdflt.c
        1. Added initialization of the new color_info.opmode field to
           gx_device_fill_in_procs.
        2. In get_decode_color, added special case handling for canonical 1-bit
           CMYK devices (e.g.: pkmraw). Previously the decode_color method for
           this devices would default to gx_default_cmyk_decode_color, which
           performed an CMYK ==> RGB ==> CMYK conversion. This conversion would
           defeat overprinting if gray object was placed on top of a colored
           region.

      src/gscolor.c
      src/gscolor2.c

      src/gsstate.h
      src/gxcmap.c
      src/gxcspace.h
      src/zcolor.c
        Modified the overprint code to, when necessary, pass overprint mode
        information when setting the device color. This is necessary to properly
        handle overprint mode when using the command list device.

        NB: This change alters the meaning of the "effective_overprint_mode" field
            in the imager state.

      src/gxdevcli.h
        Added the opmode and process_comps fields to the gx_device_color_info
        structure. These are required by the new code that passes overprint mode
        information when the device color is set.

      src/gsdfilt.h
        Changed the prototype for the push method in the gs_device_filter
        structure to match the actual implementation and usage of this method
        (the third and fourth operands were reversed).

      src/gsimage.c
        Modified gx_image_cleanup to check if penum->info field is null before
        calling gx_image_end. This avoids a crash associated that can occur if
        an image has zero height or width, as the image enumeration data structure
        will have been released in such cases before gs_image_cleanup is called.

      src/lib.mak
        Updated various dependency lists.

    Due to a combination of corrections by Russell Lang and Jan Stoeckenius, we
    have corrected a problem - twice. Unfortunately this is an example of two
    rights making a wrong. Thanks to Jan for noticing this. (gsdfilt.h [1.8]:
    2002/10/08 23:02:31 dan)

    Corrects an unitialized variable warning in image_render_color(). The

    posture case. (gxicolor.c [1.7]: 2002/10/10 19:30:42 giles)

    Correct handling of text when the pixel depth is 56 bits. (gdevm56.c [1.2]:
    2002/10/11 05:58:22 dan)

    Modified the dci_alpha_values macro to assume that devices with depth >=
    16 have a separable and linear color encoding. (gxdevcli.h [1.15]:

# Version 7.30 (2002-09-07)

This is an alpha testing release of the new DeviceN implementation. In addition, there have been numerous bug fixes and further cleanup in the pdfwrite device.

Unfortunately, documentation for the DeviceN changes was not available in time for this release.

The following SourceForge bug numbers were open at the time of the last release: 405342, 407342, 414947, 414985, 423838, 434277, 446344, 446672, 458261, 458775, 458780, 459647, 465720, 465936, 468762, 484752, 484753, 485510, 487953, 493348, 495319, 505429, 508081, 509646, 510808, 513905, 517349, 526099, 526491, 528647, 530011, 530588, 533467, 535366, 535752, 535836, 538033, 538428, 542848, 543185, 546823, 552989, 554076, 557177, 558151, 558435, 560508, 562103, 563287, 567421, 567487, 567487, 567604, 567773, 569573, 570772, 572119, 573744, 576591, 578838, 578865, 580029, 582471, 583413, 584990, 590979, 591768, 592160, 592164, 592833, 592837, 592841, 592925, 592930, 594291, 594582, 595375, 595378, 595760, 596009, 596228, 596284, 596394, 598014, 598746, 600281, 600288, 600855, 601255, 601336, 601694, 601704, 602016, 602739, 602995, 603003, 603157, 603577, 603689, 603934, 604884 604886, 605200, 605830.

In addition, a significant number of regressions remain. See the archives of the regression report for more details.

### Incompatible changes

A number of DeviceN changes can cause incompatibility. They are summarized below.

    * gx_color_index may now be 32 or 64 bits, determined at compile time.

    * The gx_device_color_info field has been updated to include
      significantly more information about the encoding from colors in the
      process color model to gx_color_index colors. New fields include:
      polarity, gray_index, separable_and_linear, comp_shift, and comp_bits.
      Devices are strongly encouraged to set these new fields correctly.
      See gxdevcli.h for more information.

    * Some existing device procedures for color mapping have changed.
      map_rgb_color now takes a cv[] array rather than separate red, green,
      and blue scalar color values, and similarly for map_cmyk_color.

    * New device procedures: get_color_mapping_procs, get_color_comp_index,
      encode_color, decode_color. These device procedures are required for
      devices defining additional colorant planes, and may be desirable for
      finer control over color mapping. See gxdevcli.h and gxcmap.c for
      more information.

## Procedures

    Fixes problems:
    	- Fixing syntax errors and potentially dangerous warnings with MSVC
    after DeviceN merge. (lib.mak [1.91]: 2002/08/22 10:00:48 igor)
    	- Logic to invoke banding was confused. Banding gets used when the
    bandsize is too small for the full page raster. A bandsize of 10000 causes
    banding. (toolbin/tests/gstestgs.py [1.12]: 2002/09/04 23:09:12 ray)
    	- Provide an implementation of popen for Windows, to avoid the
    broken implementation in MSVC++ 5 and 6. This allows pswrite to output to a
    pipe on Windows. Fixes SourceForge bug #482038, pswrite does not write to
    pipe. (winlib.mak [1.17]: 2002/09/05 08:34:00 ghostgum)
    	- Fix : The "Fix: add missing header for isxdigit()." missed the
    dependency update in devs.mak . (devs.mak [1.71]: 2002/09/05 08:50:53 igor)

    Remove gdevht.c and gdevht.h. Also delete outdated references in lib.mak and
    a few other files. (lib.mak [1.94]: 2002/09/04 06:36:36 dan)

    Changes required for compilation on HPUX and Tru64. Add missing header in
    lib.mak after gxdcolor.h added to gscolor3.c. Change dci_std_color_bits
    macro to prevent a divide by zero, caused by the compiler not using shortcut
    evaluation in an initializer. (lib.mak [1.95]: 2002/09/04 21:44:14 ghostgum)

## Drivers

    Fixes problems:
    	- FILE_IMPLEMENTATION=fd results in mixed use of unbuffered and
    buffered output but the rest of the driver always uses buffered output.
    Flushing the buffer in several places solves the problem. Fixes bug #427347.

    (lib/pdf_font.ps [1.42]: 2002/08/13 15:32:51 ray)
    	- Extra 'ifelse' in a pdfformaterror case when the Widths array was
    smaller than the character range. No SF bug, but fixes George.pdf for
    Artifex customer #1 (their support ticket 1-2398). (lib/pdf_font.ps [1.43]:
    2002/08/28 07:07:08 ray)
    	- Improve accuracy of transparency detection logic. Fixes SF bug
    #586595. (lib/pdf_main.ps [1.56]: 2002/08/28 17:34:16 raph)
    	- Partial fix to 600855 to allow the pdfwrite (Distiller) to learn
    the original font name as well as the unique font name generated by the PDF
    interpreter when it copies a font and changes the Metrics and/or Encoding.
    The FontName was made unique by appending a series of ? chars until a unique
    name was generated. Now the suffix string itself is also defined in the
    modified font dictionary with the /FontNameSuffix key. The pdfwrite text
    handling needs to be modified to use this information.

    	- The technique used to prevent PageSize dimension of 0 silently set
    the page size to 6 points whenever the dimension was < 6. Now either
    dimension of 0 causes configurationerror from setpagedevice, but small
    non-zero values are allowed if the InputAttributes allows it. Fixes

    Modified files: src/gstext.h src/gstext.c Added the routine
    gs_text_update_dev_color, to update the color used for drawing text if this
    changes during a text operation (e.g.: due to the action of a kshow or cshow
    procedure). src/zchar.c Modified op_show_continue to call
    gs_text_update_dev_color in case a cshow or kshow procedure changed the
    current color (strictly speaking, this is only a problem with kshow).

      src/zchar.c
        These files are identical to the set released on Aug. 23rd (the fix
        for color changes in a kshow procedure). We are releasing them again
        here to make certain the rest of this code is not committed without

    From ORIMP: Modified files: src/gsht.c: In gx_imager_dev_ht_install, the
    comp_number field in the entries for the newly allocated components_array
    was improperly assigned, due to a typo. Later code checks if the comp_number
    value matches the component index and, if not, uses the default halftone
    order for this component. This would cause a typical 4-color device to
    always use the default halftone component (and leak memory). As part of the
    same fix, some redundant code in gx_imager_dev_ht_install has been removed,
    and the code that updates the "used_default" variable in this procedure has
    been corrected. (gsht.c [1.7]: 2002/08/23 07:43:30 dan)

    Modified files: src/gstext.h src/gstext.c Added the routine
    gs_text_update_dev_color, to update the color used for drawing text if this
    changes during a text operation (e.g.: due to the action of a kshow or cshow
    procedure). src/zchar.c Modified op_show_continue to call
    gs_text_update_dev_color in case a cshow or kshow procedure changed the
    current color (strictly speaking, this is only a problem with kshow).
    (gstext.c [1.10], gstext.h [1.7]: 2002/08/26 22:51:53 dan)

    Modified files:

      src/gdevdbit.c:
        Changed gx_default_fill_mask to use the fill_masked routine of the
        device color. This avoids an instance in which a possibly
        uninitialized halftone tile is used for drawing. It also makes the
        code considerably cleaner.

      src/gscdefs.h
        Re-installed the definition of extern_gs_find_compositor, which had
        in-advertently been lost in a recent code merge.

      src/gsdcolor.h
        Added the colors.binary.b_level field to the gx_device_color_saved
        structure. Also added a comment explaining why this structure is
        used rather than the gx_device_color structure itself.

      src/gsht.c
        This file should be identical to the version released on Aug. 22nd.
        We are releasing again here just to guard against this code being
        committed without the former change.

      src/gsht1.c
        Modified the check for "binaryness" of a device color model in
        gs_sethalftone_try_wts to handle cases in which not all of the depth
        bits are used.

      src/gstext.c,
      src/gxtext.h
      src/zchar.c
        These files are identical to the set released on Aug. 23rd (the fix
        for color changes in a kshow procedure). We are releasing them again
        here to make certain the rest of this code is not committed without
        the former change.

      src/gxacpath.c
        Modified gx_cpath_accum_end to set the new bbox_accurate field rather
        than the bbox_set field. This avoids overloading the bbox_set field
        in a way that can lead to inconsistent output when the setbbox
        operator is used with a path.

      src/gxcht.c
      src/gxht.c
      src/gxdcolor.c
      src/gxdcolor.h
        Modified the "write" methods for various color spaces so that their
        return value can indicate that the operand and last transmitted
        colors are the same. Also fixed various bugs uncovered when the
        modular device color serialization/de-serialization was first used.
        The changes to gxdcolor.h involve only comments.

      src/gxcldev.h
        1. Added a saved device color (gx_device_color_saved) to the band
           state structure.
        2. Removed the (long since unnecessary) type operand from the
           cmd_put_halftone procedure.
        3. Commented out some now obsolete command codes.

      src/gxclimag.c
        1. Modified clist_fill_mask to work with the new, modular drawing
           color serialization/de-serialization routines.
        2. Rewrote cmd_put_halftone as required by the new mechanism for
           serializing/de-serializing device halftones.
        3. Modified various invocations of cmd_put_halftone to discard the
           the type operand.

        Note: The existing code impose a requirement that image objects that
              used a device color (e.g.: image masks) would only be passed
              through the command list if that color is pure. We do not
              know why this limitation was necessary, and suspect it is no
              longer necessary, but we have left it in place for now.

      src/gxclist.c
        Added gxdcolor.h to the included file list.

      src/gxclpath.c
        1. Rewrote cmd_put_drawing_color to use the new mechanism for
           serialization/de-serialization of device colors.
        2. Removed the device color type information from the stroke/
           fill/polyfill commands.
        3. Modified cmd_put_path so that "moveto closepath" is not
           passed through the command list as just "moveto".

      src/gxclpath.h
        1. Added the cmd_opv_ext_put_ht_seg, to allow device halftones to be
           split across multiple command buffers. Also added the macro
           cbuf_ht_seg_max_size, to indicate the largest halftone segment to
           be put in a single command buffer.
        2. Commented out some now obsolete command codes.
      src/gxclrast.c
        1. Modified the code to read device halftones and device colors to
           use the new serialization/de-serialization methods for these
           structures.
        2. Modified various locations in which partial/temporary device
           colors are used to use the current color for the band.
        3. Removed code for the various stroke/fill/polyfill commands that
           encode device color type as part of the command.
        4. Added code to save the current color when a pure color must be
           set to generate a clip region using the fill procedure.
        5. Modified the clip path reading code to flatten the clip path
           before passing it to the fill operation. This is necessary to
           ensure consistent results between the banded and non-banded
           cases (the non-banded case also flattens a clip path before
           passing it to the fill operation).

      src/gxdhtserial.c
        1. Updated gx_ht_read_tf and gx_ht_read_and_install to properly
           use the reference count in a transfer function.
        2. Fixed various other errors discovered when this code was first
           used.

      src/gxdhtserial.h
        Fixed typo.

      src/gxpath.c
        Initialize the new bbox_accurate field of the gx_path structure to
        false in gx_path_init_contents.

      src/gxpath2.c
        Modified gx_path_bbox to use the bbox_accurate rather than bbox_set
        field to determine if the bounding box of a path needs to be
        explicitly calculated. If bbox_set is true, the bounding box
        in the bbox field will contain the current path, but may be larger
        than necessary. Due to a problem in the clip/fill code, the larger
        bounding box may generate slightly inconsistent results.

      src/gzpath.h
        Added the bbox_accurate field to the gx_path_s structure. This field
        is used by the clip accumulator device, which avoids the need to
        overload the bbox_set field (which is also used by the setbbox
        operator).

      src/lib.mak
        Updated varius dependency lists.

    Another fix of a problem that had been previously fixed and lost due to a
    commit of files from ORIMP. MSVC will not accept { } for a structure
    initializer. Added a zero to keep MSVC happy. Problem previously fixed by
    Igor. (gsht1.c [1.10]: 2002/08/26 23:07:00 dan)

    We have traced the difficulties with multiple-band processing in the code
    we released on Aug. 26 to two problems:

      1. The halftone phase information is not adjusted for bands that
         start at locations other than the top of the page.

      2. The "moveto closepath" style of degenerate path, which our code
         allows to be passed through the band list, is used in the path
         encoding code to indicate that a path lies entirely outside the
         current band (i.e.: all of the path operators between the initial
         moveto and the final closepath have been skipped because they are
         outside of the band). This resulted in the code passing isolated
         "closepath" segments through the command list, which much confused
         the band list renderer.

    The attached code release fixes both of these problems, and a couple of
    other more minor issues we discovered. With this change, our system has
    identical output for the banded and unbanded case for the pkmraw device
    at 300 dpi, for all but one FTS file (027-09.ps). In that one case, the
    banded and unbanded output are visually identical, so the output difference
    may not be significant. We will look into this situation, and test some
    of the other devices in the next day or so.

    As best we can tell, halftone phase adjustment has never been correctly
    implemented for the command list device. The pre-DeviceN code handles
    binary halftone colors properly, but does not set the phase for general
    colored halftones. General colored halftones are much more common in the
    DeviceN code, which probably is the reason Dan first noticed the problem
    with FTS file 245-07.ps (and others) with the DeviceN code.

                                                             Jan

    Modified Files:

      src/gsht.c
        Modified the code that calculates the lcm_height field of a device
        halftone in gx_imager_dev_ht_install to use the full_height rather
        than the height of a halftone order. This typo was introduced sometime
        during the DeviceN development; the pre-DeviceN code was correct.

      src/gsptype1.c
      src/gsptype2.c
      src/gxwts.c
        Added the "get_phase" method to various gx_device_color_type_t
        instances.
      src/gxcht.c
      src/gxht.c
        Added the "get_phase" method to a pair of gx_device_color_type_t
        instances. Also modified the "write" and "read" methods of these
        structures to ignore halftone phase information. This information
        must be passed to and be directly handled by the command list
        writer code, so that the command list renderer code may correct it
        for the band starting coordinates.

      src/gxclpath.c
        1. Modified cmd_put_drawing_color to directly handle halftone phase
           information, using the new "get_phase" method of device colors.
           The passing of this information must be perfomed at the command
           list level, so that the command list renderer can correct the
           phase for the starting point of the band.
        2. Also in cmd_put_drawing_color, "unset" the saved color information
           if the halftone id does not match the most recently set halftone,
           rather than setting the saved color pointer to 0.
        3. In cmd_put_path, when processing a segment containing a
           moveto followed by a closepath, check if the moveto was to a point
           outside of the current band, and discard the closepath if this
           is the case. This is necessary to avoid inserting isolated
           closepath segments into the command list.

      src/gxclrast.c
        Added code to initialize the dev_color variable to clist_playback_band
        to "no color".

      src/gxdcolor.c
      src/gxdcolor.h
        Added the "get_phase" method to the gx_device_color_type_t structure,
        and installed this method in various instances of the structure. Also
        provided the two canonical implementations of this method.

    The two files were missed in earlier commits. Missing from the 8-28-02
    commit form ORIMP. src/gxdcolor.c Added the "get_phase" method to the
    gx_device_color_type_t structure, and installed this method in various
    instances of the structure. Also provided the two canonical implementations
    of this method. Missing from the 8-26-02 commit from ORIMP.
    src/gxdhtserial.c 1. Updated gx_ht_read_tf and gx_ht_read_and_install to
    properly use the reference count in a transfer function. 2. Fixed various
    other errors discovered when this code was first used. (gxdcolor.h [1.9],
    gxdhtserial.c [1.2]: 2002/08/29 00:11:30 dan)

    The attached code fixes a minor problem introduced in our release
    of August 26th. That release changed the behavior of the gx_path_bbox
    procedure (gxpath2.c) so as to make the banding and non-banding cases
    consistent. In the process we inadvertently also changed the behavior
    of the pathbbox operator. This fix restores the proper behavior of
    that operator.

    Also included is a modified version of gsht.c for interim use. This is
    not intended for final release. The gx_imager_dev_ht_install routine
    is modified in this code to ensure that the halftone caches are also
    made large enough to provide (at least) one tile per level. Doing so
    avoids the cache overwrite bug that Dan has described, which avoids
    many spurious differences in the regression test. Once Dan's fix for
    the handling of the halftone tile in binary halftone colors is
    installed, this version of gsht.c may be discarded.

    Modified files:
     src/gspath1.c
        Modified gs_upathbbox to call gx_path_bbox_set rather than
        gx_path_bbox. The former will return the bounding box set via the
        setbbox operator, if that operator has been used for the current
        path; otherwise it will return the actual path bounding box. The
        latter will always return the actual path bounding box.

      src/gxpath.h
      src/gxpath2.c
        Added the gx_path_bbox_set procedure, which will return the
        bounding box set by the setbbox operator if that operator has been
        used for the current path.

    Temporary Files:

      src/gsht.c
        Modified the gx_imager_dev_ht_install procedure to always allocate
        caches large enough to provide (at least) one tile per level. This
        is a temporary hack to avoid a bug with the handling of tiles for
        binary halftone colors. It is not intended for the final release.
    (gsht.c [1.10], gspath1.c [1.7], gxpath.h [1.6], gxpath2.c [1.6]:

    This is a repeat of an earlier commit that was backed out. Its back. Split
    the binary half tone cache initialization into two pieces. The halftone
    cache is now initialized just prior to being used in the various halftone
    render routines. This was done to prevent a problem with cache conflicts. If
    the half tone cache is not large enough for a separate tile for each level
    then there could be a problem if two different device colors used the same
    cache entry but with different level values. (gxht.c [1.11],
    gximono.c [1.8]: 2002/08/30 04:39:10 dan)

    A line was left out of the previous commit. This is part of the splitting of
    the load the binary halftone cache until it is ready to be used.
    (gxht.c [1.12]: 2002/08/30 06:19:54 dan)

    Modified File: src/gxdevndi.c Modified gx_render_device_DeviceN to always
    perform the conversion from color component intensity values to halftone
    levels in an additive sense, if the gray_colorspace operand is true. This is
    necessary for compatibility with the pre-DeviceN code. (gxdevndi.c [1.2]:
    2002/09/03 02:58:48 dan)

    Remove gdevht.c and gdevht.h. Also delete outdated references in lib.mak and
    a few other files. (gxclrast.c [1.20], gxclread.c [1.9]: 2002/09/04 06:36:36

    Changes required for compilation on HPUX and Tru64. Add missing header in
    lib.mak after gxdcolor.h added to gscolor3.c. Change dci_std_color_bits
    macro to prevent a divide by zero, caused by the compiler not using shortcut
    evaluation in an initializer. (gxdevcli.h [1.12]: 2002/09/04 21:44:14

    Add redundant parentheses to dci_std_color_bits macro to work around MSVC 7
    internal compiler error. (gxdevcli.h [1.13]: 2002/09/05 21:19:20 ghostgum)

                the gray component does not exist, the initial component will be used.

              src/gxshade.c
                Modified shade_init_fill_state to use the order of the initial component
                of the current device halftone, rather than the default order. This avoids
                use of the (no longer initialized) default order.

            Attached is the second installment of the code for modular serialization
            of device color in the command list. This release includes all of the
            necessary support code, but this code has not yet been hooked into the
            command list devices (writer and reader). That should be accomplished in
            a few days.

                                                                          Jan

            Files Added:

              gsserial.c        These two files provide a extended and public version
              gsserial.h        of the little-endian integer encoding used by the
                                command list. Since serialization can occur
                                outside of the command list, it is reasonable to have
                                this facility become a general utility. (For now,
                                at least, the command-list specific version of this
                                encoding remains as well.)

                                gsserial.c includes a unit-test.

              gxdhtserial.c     Code to serialize device halftones. These are serialized
              gxdhtserial.h     as a unit, rather than using separate commands for
                                separate pieces.

            Files Modified:

              gsdcolor.h        Removed the no longer used screens field from the wts
                                field of the colors union of the gx_device_color
                                structure.

                                Added the gx_device_color_saved structure, which may be
                                used by the command list device to retain information
                                about the last device color placed in a band. Using this
                                information can reduce the size of the newly encoded
                                color.

              gxdcolor.h        Added methods to the gx_device_color_type_t method
                                vector to support serialization of device colors. The
                                new methods are:

                                  save_dc
                                    Create a "saved" version of the device color. The
                                    saved version contains information about the
                                    device color, but does not include any pointers.
                                    It can be used to reduce the amount of information
                                    encoded with a device color.

                                  get_dev_halftone
                                    Return the device halftone used by a device color
                                    (or a null pointer if no device halftone is used).

                                  write
                                    Serialize the device color.

                                  read
                                    Reconstruct the device color from its serial
                                    representation.

                                Also added prototypes for two utilities to be used
                                when serializing device colors: gx_dc_write_color
                                and gx_dc_read_color. These work on color indices.

              gxclpath.h        Added the codes for cmd_opv_ext_put_halftone and
                                cmd_opv_ext_put_drawing_color.

              gxpcolor.h        Added prototypes for gx_dc_pattern_save_dc,
                                gx_pattern_dc_write, and gx_dc_pattern_read. Since
                                patterns cannot be passed through the command list,
                                all of these just return errors.

              gsptype1.c        Added stubs for the new device color methods. The
              gsptype2.c        get_dev_halftone method is supported to the extent
                                possible; it cannot be supported for color
                                PatternType 1 patterns as their PaintProc procedures
                                may use multiple patterns.

              gxcht.c           Added support for the new device color methods for
                                general (colored halftone ) device colors, including
                                full serialization support.

              gxht.c            Added support for the new device color methods for
                                binary halftone device colors, including full
                                serialization support.

              gxdcolor.c        Added support for the new device color methods for
                                the "no color", transparent, and pure device colors,
                                including serialization support. Also added the two
                                utility routines gx_dc_write_color and
                                gx_dc_read_color, which work on color indices.

              gxwts.c           Added stubs to support the new device color methods.
                                Also corrected a few minor compiler complaints.

              lib.mak           Added targets for gsserial.$(OBJ) and
                                gxdhtserial.$(OBJ). Also updated some dependency
                                lists.

            * zcolor.c [1.8] (+1 -2):
            Modified Files: (jan)

              lib/gs_cspace.ps
                Added _setcolorspace_nosub, a variation of the setcolorspace operation that
                avoids color space substitution. This is required for ICCBased color spaces,
                as they may be used to substitute for a device-specific color space, but
                use that same device-specific color space as an alternative space. If the
                alternative space was used (or even if it wasn't, in the prior code), an
                infinite loop would result (the eventual error is execstackoverflow).

              lib/gs_icc.ps
                Modified the cs_install routine for ICCBased color spaces to use the new
                _setcolorspace_nosub procedure.

              lib/pdf_draw.ps
                Removed the color substitution scheme used by resolvecolorspace. This has
                been superseded by the PostScript-based scheme.

              lib/pdf_main.ps
                Implemented color space substitution using PostScript's method. This works
                for all color spaces and, with the above noted modifications to
                gs_cspace.ps and gs_icc.ps, avoids infinite-loop problems. The
                earlier code did not implement color space substitution for
                DeviceCMYK (the code was just missing) and in rare cases could
                suffer from infinite loops.

              src/zcolor.c
                Correct a typo: the .setdevcspace operator was included twice in the
                zcolor_op_defs array.

            gsht1.c [1.9] (+31 -14), gsht.c [1.15] (+556 -190):

            This is the first part of the code we are providing to allow device
            colors to be passed through the command list in a modular manner. The
            rest of the code should be released within a couple of days. We are
            providing this code first because we need to fix these leaks in order
            for the rest of the code to function correctly, but these fixes are
            otherwise independent of that code.

              src/gsht.c:

                a. Added a (moderately hack-ish) mechanism to allow halftone
                   components to share well-tempered screens. This mechanism uses the
                   width field of the halftone component, which is nominally not used
                   for well-tempered screens, to indicate which component "owns" the
                   screen and can release it.

                b. Modified gx_ht_alloc_ht_order and gx_ht_copy_ht_order to handle well-
                   tempered screens, which do not have levels or bid_data arrays.

                c. Created gx_ht_move_ht_order, an analog to gx_ht_copy_ht_order, that
                   assumes ownership of the structure's reference by a source halftone
                   order rather than copying them.

                d. Modified gx_ht_order_release to handle well-tempered screen
                   component orders, and to decrement the transfer function
                   referenced by a halftone order (as opposed to blindly releasing
                   it).

                e. Completely re-wrote gx_imager_dev_ht_install, to fix various memory
                   leaks and better handle well-tempered screens. See the comments
                   in the procedure for additional information.

                f. Modified gx_ht_install to take ownership of all structures referenced
                   by the operand device halftone, if it returns successfully. This
                   matches the behavior of the pre-DeviceN code and is required by
                   various clients to avoid memory leaks. Any referenced structures
                   that are not required by the device halftone in the imager state
                   will be released (again, only on successful completion).

                g. Modified gx_imager_set_effective_xfer to ignore the "default"
                   order in a device halftone. This order is not used for device
                   halftones installed in the imager state, and
                   gx_imager_set_effective_xfer should only be called for device
                   halftones installed in the imager state.

              src/gsht1.c:
                a. Modified gs_sethalftone_allocated to release any unused parts
                   of the device halftone in the event that gx_ht_install returns
                   with an error code.

                b. Modified gs_sethalftone_prepare to not allocate a cache for
                   (traditional) halftone orders.

                c. Modified process_transfer to set a reference count of 1 in the
                   transfer functions. This is appropriate, as the routine
                   sets a reference to these structures (in the halftone component
                   order).

                d. Simplified the check for bi-level device in gs_sethalftone_try_wts.

                e. Used gs_alloc_struct_array in place of malloc for allocating the
                   component order array in gs_sethalftone_try_wts.

                f. Set the num_bits and num_levels values in well-tempered screening
                   halftone orders to 0. This setting is required to allow them to
                   be correctly handled by gx_ht_copy_ht_order.

                g. Added processing of halftones to gx_sethalftone_try_wts.

              src/gshtscr.c:
                Modified gs_screen_install to discard any structures referenced by
                a device halftone if gx_ht_install returns an error code.

              src/gshtx.c
                Modified gs_ht_install to discard any structures referenced by
                a device halftone if gx_ht_install returns an error code.

              src/gswts.c
                Added the procedures gs_wts_free_enum and gs_wts_free_screen, to
                free gs_wts_screen_enum_t and wts_screen_t structures.

              src/gswts.h
                Added prototypes for the procedures gs_wts_free_enum and
                gs_wts_free_screen. These are used by the device halftone
                code to free gs_wts_screen_enum_t and wts_screen_t structures.

              src/gxclrast.c
                Added code in read_set_ht_data to discard just the allocated
                halftone components array, but not any of the structures
                it references, after gx_imager_dev_ht_install returns. This is
                necessary as gx_imager_dev_ht_install will always copy this
                structure, and cannot release the original.

                NB: This is an interim change. The mechanism by which halftones
                    are passed through the command list will change shortly.

              src/gzht.h
                Modified the prototypes for gx_imager_dev_ht_install and
                gx_ht_install to remove the const qualifier for the device
                halftone operand.

            * int.mak [1.7] (+8 -3):
            The zcolor3.c module was accidently dropped.  THis module is needed for
            the UseCIEColor feature.

            The data section of the gray transfer component (from the setcolortransfer
            operator) and the 'default_comp' were not both being updated properly.
            This resulted in gray transfer functions not being transfered properly
            through the clist.  The fix involves simply removing the 'default_comp'
            and using the gray component for the default and for the settransfer
            operator.

            There was an improper check which was excluding the zeroth component

            routine were special casing 1, 3, and 4 components cases and assuming
            that there were Gray, RGB, and CMYK.  This did not work for DeviceN
            colorspaces.  The fix involves using the colorspace remap_color
            routine instead of going directly to the cmap_procs.  This should be
            slightly slower (but will work in all cases).

            (Jan) Implements the overprint and overprint mode features for the
            PostScript and PDF writer devices. These devices have supported the
            overprint feature for some time. The modifications allow them to
            intercept and discard the create_compositor invocation for the
            overprint compositor, as they don't need the compositor and already
            access overprint information from the imager state.

            Note: This set of changes is quite simple, but we have no easy way to
                  test the result. Hence, while we believe it very unlikely the
                  changes will cause discrepancies, we have not actually tested
                  them (other than to verify compilation).

            Modified files:

              src/devs.mak
                Updated dependency list for gdevpsdu.$(OBJ).

              src/gdevpdf.c
                Added the methods psdf_get_bits, psdf_get_bits_rectangle, and
                psdf_create_compositor to the method vector initialization of the
                gs_pdfwrite_device.

              src/gdevps.c
                Added the methods psdf_get_bits, psdf_get_bits_rectangle, and
                psdf_create_compositor to the method vector initialization of the
                gs_pswrite_device and gs_epswrite_device.

              src/gdevpsdf.h
                Added prototypes for the psdf_get_bits, psdf_get_bits_rectangle,
                and psdf_create_compositor procedures.

              src/gdevpsdu.c
                Added the psdf_get_bits, psdf_get_bits_rectangle, and
                psdf_create_compositor procedures. The first of these just returns
                an unregistered error. The prior code also generated an error if
                these methods were called, but via a much more obscure and round-
                about route. The psdf_create_compositor procedure recognizes and
                discards invocations of the create_compositor method for the overprint
                compositor. The PostScript and PDF writers do not need this compositor
                to support overprint, and would fail if it were present as it
                requires support for the get_bits/get_bits_rectangle methods.

            Patch from Russel Lang  (gsview@ghostgum.com.au)

            Anti-aliasing for CMYK devices did not work because
            gx_default_copy_alpha converted the new and existing pixel
            values to RGB, merged them then remapped the result. This
            patch uses decode_color on the two pixels, merges the pixel
            color values individually, then uses encode_color on the
            result.

            To avoid flashes of incorrect colour begin displayed when
            the display device size is changed, the display device
            erases the page to white immediately after bitmap
            allocation. Actually, it was erasing the colour to
            RGB(1.0,1.0.1.0) by calling map_rgb_color, which actually
            calls encode_color which is expecting CMYK as input.  This
            resulted in a black background. This patch changes the code
            to use encode_color with appropriate values for DeviceGray,
            DeviceRGB or DeviceCMYK.

            The display device did not work with CMYK anti-aliasing
            because the decode_color procedure was decoding to RGB, not
            CMYK.  This patch adds new cmyk_[18]bit_map_color_cmyk
            functions for decode_color.

                they are now just set to safe values (colors_and = 0;
                colors_or = (x_pixel)(-1)).

            The following should be prominently posted in full view of all
            software engineers:

              ***Do not use caches to hold unreplaceable data***

            Failure to follow that rule of good programming is the heart of the
            problem with FTS panel 245-04 (file 245-01.ps).

            The immediate cause of the problem is the optimization put in the
            setcolorspace code to avoid repeatedly setting the same color space.
            The steps that lead to the error are the following:

              1. The job sets a CIEBasedABC color space as the current color
                 space. The white and black point information from the color
                 space dictionary is combined with the white and black point
                 information in the color rendering dictionary to sample the
                 TransformPQR procedures in that dictionary. The resulting
                 data is placed in the joint CIE cache. All of this activity
                 ends with an execution of the internal operator cie_tpqr_finish
                 (zcrd.c). This operator has two side-effects:

                     The TransformPQR data structure in the cie_render structure
                     of the current state is set to TransformPQR_from_cache, which
                     indicates that the PQR phase of the CIE color mapping (the
                     white point point adjustment) is to be done via the joint CIE
                     cache.

                     The gs_cie_cs_complete procedure is invoked with the "init"
                     argument set to false, indicating that no further
                     initialization is required for the joint CIE caches. This
                     causes the status flag in those caches to be set to
                     CIE_JC_STATUS_INITED, indicating that the caches are ready
                     to use.

              2. The job calls gsave. Since the joint CIE caches can be shared by
                 multiple graphic states, the cache reference count is incremented.

              3. The job sets a pattern color space, whose base color space is the
                 current (CIEBasedABC) color space.

                 The PostScript interpreter in Ghostscript uses the convention that
                 a base or alternative color space will always be set as the current
                 color space immediately before the enclosing color space is set.
                 The cs_install procedure for the pattern color space
                 (lib/gs_patrn.ps) invokes setcolorspace on the base space. Because
                 this is already the current color space, nothing happens.

              4. Immediately afterwards, the cs_install procedure invokes the
                 .setpatternspace operator on the enclosing pattern color space.
                 Through a couple of layers, this will invoke the "install_cspace"
                 method for pattern color spaces, the gx_install_Pattern
                 (gspcolor.c). This will in turn invoke the "install_cspace" method
                 for the base color space, in this case gx_install_CIE.

              5. Through a few additional layers, gx_install_CIE will also call
                 gs_cie_cs_complete (see (1) above), but this time the "init"
                 variable will be set to true, indicating that additional
                 initialization is required.

                 gs_cie_cs_complete will invoke gx_currentciecaches, whose purpose
                 is to make sure that new copies of the joint CIE cache is created
                 when necessary. Since the reference count on the existing cache is
                 larger than 1 (see (2) above), a unique copy of the cache is created
                 and is marked as invalid.

              6. Subsequently, when drawing is attempted in the base color (the
                 pattern has PaintType 2), the code will note that the cache is
                 not yet valid and invoke cie_joint_caches_init (gscie.c). This
                 routine can do nothing, however, because the TransformPQR structure
                 for the cie_render structure in the graphic state is set to
                 TransformPQR_from_cache, indicating that the only data available
                 for the TransformPQR procedure is in the (now invalidated) cache.

                 As a fall-back, the CIE color is mapped to RGB by setting all
                 components to 0, which yields the black output.

            The proper fix for this problem is re-designing both the CIE color space
            and the color rendering structures so that they retain enough information
            to regenerate the joint CIE cache when necessary. Since that is a big
            change, the attached modifications take the more modest approach of adding
            a "forcesetcolorspace" operator, which will set a color space even if it
            is identical to the current color space.

            Also included in the set of changes is a minor modification to gs_rectfill
            (gsdps1.c) that suppresses direct access to the device's fill_rectangle
            procedure if both overprint and overprint mode are true. Since
            overprintmode must be applied prior to halftoning, the code must be forced
            through one of the higher-level methods which include the pre-halftoned
            device color information.

            Modified files:

              lib/gs_cspace.ps
                Added the _setcolorspace procedure, which accepts both a boolean and
                a color space dictionary. If the boolean is true, the color space
                will not be set if it is the same as the current color space (via a
                conservative evaluation).

                The setcolorspace pseudo-operator now invokes _setcolorspace with the
                boolean operand set to true. A new operator, forcesetcolorspace,
                invokes _setcolorspace with boolean set to false.

              lib/gs_devn.ps
              lib/gs_icc.ps
              lib/gs_indxd.ps
              lib/gs_patrn.ps
              lib/gs_sepr.ps
                Replaced setcolorspace with forcesetcolorspace when setting a base or
                alternative color space. This is necessary due to some problems in the
                handling of the the joint CIE cache in the graphic library.

              src/gsdps1.c
                Modify gs_rectfill to suppress direct access of a device's
                fill_rectangle method if both overprint and overprint mode are set
                to true. This is required to make sure the overprint compositor has
                access to pre-halftoned device color information with which to
                implement overprint mode.

            Back out the last commit.  The theory is good and I still have hope for
            the concept.  However it currently creates 532 errors in the regression
            testing.  Thus it is being backed out (for now).

            Split the half tone cache initialization into two pieces.  The halftone
            cache is now initialized just prior to being used in the various
            halftone render routines.  This was doe to prevent a problem with cache
            conflicts.  If the half tone cache is not large enough for a separate
            tile for each level then there could be a problem if two different
            device colors used the same cache entry but with different level values.

            * gxicolor.c [1.4] (+13 -25):
            This commit is to remove the change from yesterday.  That commit has
            some serious flaws.  It fixed a small problem by creating some larger ones.

            There is still a flaw in the logic of image_render_color.  It is creating
            a pair of device colors.  Unfortunately, the process of creating the second
            one can change a half tone cache used by the first.  This affects the final
            image when the first color is then used to image pixels.

            * gxicolor.c [1.3] (+27 -15):
            image_render_color creates a pair of device colors and then compares them.
            Unfortunately the process of creating the second device color can alter
            the halftone cache used by the first.  This can occur when the halftone
            cache is small (4096 bytes) and there is not enough room for a cache
            entry for each level.  The fix is to reload the cache by remapping the
            first color before it is used to render a pixel.

            Note:  This problem also affects non DeviceN code but is less visible
            since a large cache (100000 bytes) is used for many situations.

                transfer of output data involves a skew (bit shift) but no color
                conversion (a case that is apparently used only by the overprint
                facility). This case uses the copy_mono method for the 1-bit
                memory device. The invocation of this method had two problems:

                  1. The temporary device created for the transfer had uninitialized
                     width and height fields. Because copy_mono will invoke the
                     fit_copy macro, these fields must be set to reasonable values.

                  2. The width passed to copy_mono must be bit-width, as the
                     method for a depth == 1 device is used. Previously, the
                     pixel width was used.

              src/gdevx.c
                Fixed a problem in x_copy_image. If the image passed to this routine
                contains more than one pixel, the colors_and and colors_or fields were
                not updated. Because these fields are only used for optimization, and
                properly updating them in this situation is potentially expensive,
                they are now just set to safe values (colors_and = 0;
                colors_or = (x_pixel)(-1)).

              src/genconf.c
                Added to "-comp" option to support construction of a list of
                compositors compiled into the system.

              src/gs.mak
                Added the SETCOMP and ADDCOMP macros, to provide access to the
                -comp option of genconf.c.

              src/gsalphac.c
                Exported the gs_composite_alpha_type structure, and added a compositor
                type identifier to this structure. Also modified the de-serialization
                (read) method for this size so that the data string provided be large
                enough but not necessarily exactly the right size, and to return the
                number of bytes actually read (or an error code).

              src/gscdefs.h
                Added a prototye for gs_find_compositor (see gconf.c above).

              src/gscolor.c
                Modified gx_set_device_color_1 to turn off overprint (and overprint
                mode).

              src/gsovc.c:
                1. Modified the de-serialization method (read) to return the number of
                   bytes actually read (or an error code).
                2. Renamed gs_overprint_type to be gs_composite_overprint_type, so as
                   to conform to the new convention for compositor names.
                3. For the overprint devices, set the get_xfont_procs, get_xfont_device,
                   and text_begin methods to use the corresponding default methods,
                   rather than the forwarding methods. Device-supported fonts are
                   incompatible with overprint, as the required low-level calls may
                   not be made. While the text_begin method is not itself a rendering
                   method, it does record an imaging device, and this device must
                   be the overprint device rather than the target device. If the
                   forwarding text_begin method is used, the recorded imaging device
                   would be the target device.
                4. Modified update_overprint_params to avoid use of the overprint
                   devices for cases in which overprint is true, but all color
                   components are to be drawn. Though the output is not changed, use
                   of the non-overprint device improves performance in this case.
                5. Modified the default overprint compositor creation method
                   (c_overprint_create_default_compositor) to ignore overprint
                   requests if the current color model has only a single component.
                   Overprinting can never have an effect in this situation, and
                   avoiding these cases also avoids difficulties with mask caching
                   devices (such as are used with the character cache).

              src/gsstate.c
                Modified gs_state_update_overprint to update the color model mapping
                procedures and unset the device color. Though updating the overprint
                status will never change the color model, the overprint devices
                require a special set of forwarding color model mapping procedures.

              src/gxclimag.c
                Implemented the clist_create_compositor procedure (the create_compositor
                method for the command list device).

              src/gxclpath.c
                Replaced the cmd_opv_put_params code (0xdf) with cmd_opv_extend. This
                code indicates that the subsequent byte should be read and interpreted
                as a command from the gx_cmd_ext_op enumeration. Currently, this
                enumeration has two elements, cmd_opv_ext_put_params (the put_params
                method) and cmd_opv_ext_create_compositor (the create_compositor
                method).

              src/gxclrast.c
                1. Made the code parsing changes required by the new cmp_opv_extend
                   code (see gxclpath.h above).
                2. Added the read_create_compositor procedure, to interpret the
                   cmd_opv_ext_create_compositor command.

              src/gxclutil.c
                Modified cmd_put_params for the new cmp_opv_extend/cmd_opv_ext_put_params
                coding techinque.

              src/gxcmap.c
                Modified gx_set_cmap_procs to handle devices that have no
                get_color_mapping_procs method (such as mask caching devices).

              src/gxcomp.h
                Added the comp_id field to the gs_composite_type_t structure. Also
                added macros for the alpha and overprint compositors (the only two
                compositors in the current system).

              src/gxoprect.c
                Fixed typo in pack_scanline_lt8: the source data pointer was not
                being advanced.

              src/gxoprect.h
                Fixed typo in RCS identifier comment.

              src/lib.mak
                1. Updated several dependency lists.
                2. Added code to generate the list of compiled compositors.

            The last version had a problem in that the gray calculation might miss
            the fact that the calculation had produced a solid color (due to rounding
            in the calculation).  Then it would access an array out of bounds.

            New Files:

              src/gxoprect.c
              src/gxoprect.h
                These files provide the low-level code for the fill_rectangle method
                of the overprint compositor device. There are three such procedures,
                which are used in different circumstances:

                  gx_overprint_generic_fill_rectangle is always applicable, but is
                    very slow as it must decode and re-encode the color for each pixel.

                  gx_overprint_sep_fill_rectangle_1 is applicable to separable and
                    linear color encodings whose depth is a divisor of
                    8 * sizeof(mono_fill_chunk) = 32. This is always the
                    case if depth <= 8. The code used in this case is, once past a
                    large amount of setup, about as fast as can be achieved while
                    using get_bits_rectangle.

                  gx_overprint_sep_fill_rectangle_2 is applicable to all other
                    separable and linear color encodings (all of which will have
                    depth % 8 = 0). This uses a byte-wise method which is in principle
                    slower than what could be achieved with a chunk-wise method, but
                    is much easier to code in the general case (i.e.: for multiple
                    possible depths). It will likely be faster in practice.

            Modified Files:

              lib/gs_init.ps
              lib/gs_setpd.ps
                Modified erasepage (and several other bits of code that erase the
                page) to turn off overprint before filling the page. This is necessary
                to preserve the meaning of erasepage.

              src/gsbitops.c
              src/gsbitops.h
                Added the bits_fill_rectangle_masked procedure, a generalization of
                the bits_fill_rectangle procedure that allows for a component mask.
                Also generalized bits_fill_rectangle (and bits_fill_rectangle_masked)
                to support depth > 8, so long as
                (8 * sizeof(mono_fill_chunk)) % depth = 0.

                Currently, bits_fill_rectangle_masked is used only by the overprint
                compositor device, but it can also be used by devices that can
                directly implement overprint (such as the memory device).

              src/gscdevn.c
                Modified check_DeviceN_component_names to initialize the
                component_map.sep_type field of the imager state to SEP_OTHER.
                Previously this field was not set for DeviceN color spaces, which
                confused some of the overprint code.

              src/gsovrc.c
                Implemented the real overprint_fill_rectangle procedures. As part of
                this work, added the local procedure swap_color_index, that swaps
                bytes in a color index as required to work with byte-oriented bitmaps
                on little-endian devices (only if depth > 8).

                Also fixed a parity bug in the creation of the retain_mask.

              src/gsovrc.h
                Fixed typo (/* $Id$ */).

              src/gxdcconv.c
                Modified color_rgb_to_cmyk to work if the imager state pointer
                operand is a null pointer. Note that in this case full undercolor
                removal and black generation will be performed, which is consistent
                with other such conversions in the code that do not have access to
                the imager state, but differs from the mapping used if the imager
                state is available but has no blackgeneration or undercolor removal
                map.

              src/lib.mak
                Added the gxoprect.$(OBJ) target and included this as a dependency
                in LIB4s. Also updated some other dependency lists.

            Additional file modified (not for overprint but needed for release):

              src/gdevdflt.c
                Added code to select a reasonable default value for the decode_color
                method, as this method is used extensively by the generic overprint
                implementation routines. The modifications are just a first pass to
                allow us to test the overprint code; they are not intended as a
                final solution.

            regression testing.

            * gdevpbm.c [1.7] (+9 -5):

            notes follow in reverse chronological order.

            Notes:

             Modified files:

              gsstate.c
                Added code to ignore an error return from the create_compositor call
                in gs_state_update_overprint if the call was made to turn off
                overprint. This avoids errors for device configurations that do not
                (yet) support the create_compositor call, when running files that do
                not require overprint support.

              gsovrc.h
                Fixed a typo in a commment.

              gxclrast.c
                Fixed a re-entrancy problem in read_set_color_space that was introduced
                by the previous modification to this file.

              gsimage.c
                Added a comment concerning re-entrancy, and slightly modified another
                comment.

              gscspace.c
                Added some comments concerning re-entrancy.

            Notes:

            Modified Files:

              src/gsovrc.c
                Added full compositor device "plumbing". The overprint compositor
                now does all of the required device creation and setup work. The
                only piece still missing are implementations of the low-level
                rendering routines that actually implement overprint.

              src/gsptype1.c
              src/gsptype2.c
              src/gxcht.c
              src/gxdcolor.c
              src/gxdcolor.h
              src/gxht.c
              src/gxpcolor.h
                Added the method get_nonzero_comps to the gx_device_color_type_t
                structure (the gx_device_color methods). This method is used by
                the overprint code to determine which color component intensities
                have non-zero value, which must be known to implement overprint
                mode.

              src/gsovrc.h
              src/gscspace.c
                Changed the drawn_comps field of the gs_overprint_params_t
                structure from a byte array to a gx_color_index. This is a bit
                ugly, as the value is a bit map rather than an encoded color,
                but allows much simpler processing. (As in device colors, a
                gx_color_index is used because it is known to be large enough.

              src/lib.mak
                Updated dependency list for gsovrc.$(OBJ).

            New Files:

              src/gsovrc.c
                Implementation of the overprint compositor. For the moment, this is
                just a stub. This file will grow considerably in the next two releases.

              src/gsovrc.h
                Interface to the overprint compositor. This is in essentially final
                form, even though only a stub implementation of the compositor is
                available. This file also includes a lengthy comment describing when
                the compositor must be updated.

            Modified Files:

              lib/gs_ciecs3.ps

                Incorporated an optimization of setcolorspace from the casper head.
                The optimization avoids setting the color space if it is the same as
                the current color space. gs_icc.ps also contains a fix for a bug
                in the handling of DataSources that are streams (rather than strings;
                Dan discovered and analyzed this bug).

                Note that this is a fairly complex optimization, and there were many
                problems with the head code that needed to be resolved. Among these
                were:

                  1. An invocation of setcolorspace should always set the default
                     color for the operand color space, even if that color space is
                     identical to the current color space.

                  2. If UseCIEColor is true, setcolorspace must be executed if
                     the operand color space involves device-specific color spaces.
                     This is because the Default{Gray,RGB,CMYK} instances of the
                     ColorSpace resource category may have changed.

                  3. When UseCIEColor is changed from true to false in setpagedevcie,
                     the implicit initgraphics invocation must perform a setcolorspace
                     operation, even if the current color space is DeviceGray. This
                     is necessary to ensure that the un-substituted DeviceGray color
                     space is set as the current color space.

              lib/gs_init.ps
                In /showpage, replace the sequence "erasepage ... initgraphics" with
                "initgraphics 1 setcolor .fillpage 0 setcolor". This has the desired
                effect, and avoids two unnecessay invocations of setcolorspace.

              lib/gs_setpd.ps
                1. Modified the currentpagedevice pseudo-operator for cases in which
                   the stored page device must be copied. Previously, the new copy
                   was allocated in the current VM mode, which could cause
                   invalidaccess errors if currentpagedevice was invoked while in
                   global VM mode and composite objects stored in the page device
                   dictionary were in local VM (this problem is present in the PS3
                   FTS). The new code will allocate the copy in the save VM as the
                   original dictionary.

                2. In setpagedevice, added code to set current color space to
                   something other than DeviceGray if modification of the page device
                   will set UseCIEColor to false. This is necessary for the
                   setcolorspace optimization to function properly (see above).

                3. In the .postinstall pseudo-operator, replaced "erasepage initgraphics"
                   with "initgraphics 1 setcolor .fillpage 0 setcolor". This avoids
                   two unnecessary invocations of setcolorspace.

              src/gdevp14.c
                Added the pdf14_create_compositor method. This method will check if
                the compositor to be created is the overprint compositor. If so,
                the request to create the compositor will simply be ignored, as
                the gs_pdf14_device and its associated marking device must implement
                overprint directly.

              src/gscdevn.c
                1. Removed the equality check method.

                2. Added the set_overprint method for DeviceN color spaces.

              src/gscolor2.c
                1. Removed the equality check method.

                2. Added the set_overprint method for Indexed color spaces.

              src/gscpixel.c
                1. Removed the equality check method.

                2. Added the set_overprint method for DevicePixel color spaces.

              src/gscscie.c
                1. Removed the equality check method.

                2. Added the set_overprint method for CIEBased color spaces.

              src/gscsepr.c
                1. Removed the equality check method.

                2. Added the set_overprint method for Separation color spaces.

                3. Moved the gs_{set|current}overprint[mode] procedures to gsstate.c.

              src/gscsepr.h
                Moved prototypes for the gs_{set|current}overprint[mode] procedures
                to gsstate.h.

              src/gscspace.c
                1. Removed the color space equality check methods for the device-
                   specific color spaces.

                2. Added the basic set_overprint procedures, to provide color-space
                   specific setting of the overprint compositor.

                3. Modified the gs_cspace_{build|init}_Device{Gray|RGB|CMYK}
                   procedures to use the same identifier for all instances of
                   the parameterless color spaces (i.e.: all DeviceGray instances
                   will have the same id, as will all DeviceRGB instances, but the
                   id for any DeviceGray will differ from the id for a DeviceRGB
                   instance). This enables an optimization in the gs_setcolorspace
                   routine that had been lost in the previous code modification.

              src/gscspace.h
                Removed prototype for the gs_color_space_equal procedure.

              src/gsicc.c
                1. Removed the equality check method.

                2. Added the set_overprint method for ICCBased color spaces.

              src/gslib.c
                Modified test9 to explicitly reset the current color space; this
                is no longer done by gs_initgraphics.

              src/gspcolor.c
                Added set_overprint method for pattern color spaces, removed the
                equality check method.

              src/gsstate.c
                1. Added code to update the overprint compositor when the current
                   color space, current device, overprint, or overprint mode
                   settings change. Included in this change is code in gs_grestore_only
                   that updates the overprint compositor as part of the grestore
                   operation when this is required.

                2. Moved the gs_{set|current}overprint[mode] procedures to this file
                   from gscsepr.c. This is more convenient for the new code, and
                   gscsepr.c was never a particularly appropriate place for these
                   routines.

                3. Modified gs_initgraphics to not reset the current color space or
                   current color. For PostScript this must now be done in the
                   PostScript code to properly handle color space substitution.
                   Other clients that use this procedure (the XL interpreter is the
                   only one (aside from gslib.c)) can easily reset these parameters
                   as well.

              src/gsstate.h
                Moved prototypes for the gs_{set|current}overprint[mode] procedures
                here from gscsepr.h.

              src/gxccache.c
                Modified gx_image_cached_char to just return if the current color
                is a pure gx_no_color_index (transparent).

              src/gxcspace.h
                1. Removed the equality check method.

                2. Added the set_overprint method.

              src/gxipixel.c
                Modified the gx_image_enum_begin to allow the Decode array for
                imagemasks to have any two distinct numbers, rather than just 0 and
                1. This matches the behavior of all Adobe systems (though not the
                documentation), and avoids some spurious failures when running the
                FTS.

              src/gxpcmap.c
                Modified pattern_accum_copy_mono to just return if both the foreground
                and background colors are gx_no_color_index (transparent). If this is
                not done, the mask device's copy_mono procedure may generate an
                error when invoked (this is true for mem_mono_copy_mono).

              src/iutil.c
                Modified obj_eq to consider two 0-length arrays to be equal,
                irrespective of their type and their pointers (the latter aren't
                meaningful if the array length is 0). This matches the PostScript
                documentation and the behavior of Adobe systems. It also fixes
                some spurious failures in the FTS.

              src/lib.mak
                Added an entry for gsovrc (the overprint compositor), and updated
                various dependency lists.

              src/zfdcte.c
                Modified the DCTEncode procedure (zDCTE) to allocate the
                jpeg_compress_data and subsidiary memory structures in current VM.
                Previously these structures were allocated in gs_default_memory,
                which does not support garbage collection. Since the structures
                were subject to garbage collection and relocation, chaos could
                and, in the case of FTS file 119-28.ps, did ensue.

                Note that these structure must be allocated immovable, which
                requires a considerable amount of overhead when using VM. A better
                approach would be to allocate them in gs_default_memory, and use
                a more sophisticated structure descriptor for the stream_DCT_state
                structure (st_DCT_state).

              src/zgstate.c
                Slightly simplified zinitgraphics, and updated a comment in this
                procedure.

              src/zmisc.c
                Modified realtime operator to set a zero point at boot time. This
                avoids an annoying delay in running FTS panel 211-01 (206-01.ps).

              zpcolor.c
                Modified the pattern_paint_prepare procedure to use gs_setdevice_no_int
                rather than gx_set_device_only. It is not clear why the latter
                procedure was ever used in this location, and it is now important to
                use the former procedure so the overprint compositor may be properly
                updated.

            Overprint implementation (Jan Stoeckenius)

            This is a preliminary code release for the overprint capability. The
            release does not contain the overprint facility itself; it consists
            entirely of modifications so that color space changes will occur in a
            predictable fashion.

            Files removed:

              src/zhsb.c

            Files added:

              lib/gs_cspace.ps      PostScript portion of the basic color space handling;
                                    see the extensive comment at the head of the file
                                    for information. Note that color space substitution
                                    and the hue-saturation-brightness (HSB) color space
                                    are now fully implemented in the PostScript code;
                                    the interpreter and the graphic library are no longer
                                    involved in or even aware of these features.

              lib/gs_devcs.ps       Implementation of the DeviceGray, DeviceRGB, and
                                    DeviceCMYK color spaces.

              lib/gs_ciecs2.ps      Implementation of the LangaugeLevel 2 CIEBased color
                                    spaces: CIEBasedA and CIEBasedABC.

              lib/gs_ciecs3.ps      Implementation of the LanguageLevel 3 CIEBased color
                                    spaces: CIEBasedDEF and CIEBasedDEFG

              lib/gs_devpxl.ps      Implementation of the DevicePixel color spaces

              lib/gs_indxd.ps       Implementation of the Indexed color space.

              lib/gs_sepr.ps        Implementaton of the Separation color space.

              lib/gs_devn.ps        Implementation of the DeviceN color space.

              lib/gs_patrn.ps       Implementation of the Pattern color space.

              lib/gs_img.ps         Implementation of the traditional (non-dictionary)
                                    form of the image and imagemask operators, and the
                                    colorimage operator (including the Next alphaimage
                                    facility). The interpreter now provides only the
                                    dictionary form of the image and imagemask operators,
                                    including a variation that provides alpha-channel
                                    support.

                                    Also modified the handling of color spaces for
                                    ImageType 2 images. This slightly changes the behavior
                                    of these images. If PixelCopy is defined to be true
                                    in the image dictionary but such a copy cannot be
                                    supported, an error will be generated. This is in
                                    agreement with Adobe's documentation, but differs
                                    from the earlier behavior.

              The code for Indexed, Separation, and DeviceN color spaces
              incorporates code, courtesy of Dan, that will invoke the lookup or
              tint transform procedure in the appropriate context if this is
              appropriate (if there is a lookup procedure for Indexed color spaces
              or the alternate color space is in use for Separation and DeviceN
              color spaces). Currently this is not done recursively (if an Indexed
              color space has a DeviceN base color space, for example), but that
              has not proven necessary in practice. If necessary, it can be added.

              src/zcolor3.c         Code to implement the .setuseciecolor operator. This
                                    operator is used only in the setpagedevice code, and
                                    makes certain that the use_cie_color field in the
                                    interpreter's graphic state mirrors the setting of
                                    the UseCIEColor page device parameter.

            Files modified:

              lib/gs_dpnxt.ps       Added PostScript implementation of the alphaimage
                                    operator. This uses the internal .alphaimage
                                    operator, which is a variation of the image
                                    operator that provide alpha-channel support.

              lib/gs_icc.ps         Rewritten to implement the ICCBased color space
                                    in the new scheme. See the comments in
                                    lib/gs_cspace.ps for information.

              lib/gs_init.ps        Modified to include gs_cspace.ps, gs_devcs.ps,
                                    and gs_img.ps, and to remove img_util_dict and
                                    .cspace_util_dict from userdict at the end of
                                    initialization.

              lib/gs_lev2.ps        All explicit color spaces removed (with one
                                    exception, and replaced by inclusion of gs_devpxl.ps,
                                    gs_ciecs2.ps, gs_indxd.ps, gs_sepr.ps, and
                                    gs_patrn.ps. The only remaining color space support
                                    feature is moving the setcolorspace and setcolor
                                    pseudo-operators, and the colorspacedict dictionary,
                                    to level2dict. This must be done here, as it is not
                                    known that level2dict exists when gs_cspace.ps is
                                    first run.

                                    Also removed all explicit image support. This is
                                    now handled by gs_img.ps (see above).

              lib/gs_ll3.ps         Removed the old support for color space substitution;
                                    this is now handled directly by the color space
                                    code (see the comments in gs_cspace.ps for
                                    information). Added inclusion of gs_ciecs3.ps and
                                    gs_devn.ps.

              lib/gs_setpd.ps       Added support for the .getuseciecolor and
                                    .setuseciecolor operators. This maintains a
                                    "mirror" of the UseCIEColor parameter in the
                                    graphic state, to allow fast access.

              src/gdevnfwd.c        In gx_forward_get_color_mapping_procs, added a check
                                    for the case of a target device which has no
                                    get_color_mapping_procs procedure. This led to a
                                    segmentation violation crash for FTS file 296-01.ps
                                    The fix may not be the correct one, as we are not
                                    certain why a device would lack this method.

              src/gdevp14.c         Replaced a use of the shared field in the graphic state
                                    with a color space allocated on the C-language stack.

              src/gdevpsdi.c        Replaced an instance of use of the gs_cspace_DeviceRGB
                                    procedure.

              src/gscolor.c         Removed gs_currentgray and gs_currentrgbcolor. Modified
                                    gs_setgray and gs_setrgbcolor to use gs_setcolorspace
                                    and gs_setcolor. This eliminates use of the
                                    gs_current_Device*_space routines.

              src/gscolor.h         Removed prototypes for gs_currentgray and
                                    gs_currentrgbcolor.

              src/gscolor1.c        Removed gs_currentcmykcolor. Modified gs_setcmykcolor
                                    to use gs_setgray and gs_setcolorspace.

              src/gscolor1.h        Removed prototype for gs_currentcmykcolor.

              src/gscolor2.c        Removed gs_currentcolorspace_index. Removed the color
                                    index tracking used as part of the color space
                                    substitution method.

              src/gscolor2.h        Removed prototype for gs_currentcolorspace_index.

              src/gscscie.c         Eliminated use of the gs_cspace_Device* routines.

              src/gscsepr.c         Fixed a pair of typos in revision 1.6 of the code.
                                    In gs_cspace_set_sepr_proc and
                                    gx_concretize_Separation, the code was still accessing
                                    pcspace->params.device_n when it wanted to access
                                    pcspace->params.separation. This caused a crash in
                                    FTS file 245-01.ps.

              src/gscspace.c        Removed gs_cspace_Device* procedures.

              src/gscspace.h        Removed prototypes for gs_cspace_Device* procedures.

              src/gsimage.c         Removed use of the gs_cspace_DeviceGray procedure.

              src/gsiparam.h        Removed the gs_image_t_int_{gray, rgb, cmyk} macros.

              src/gsistate.c        Updated code to reflect removal of the shared field in
                                    the imager state. As part of this, the
                                    rc_free_imager_shared and gx_device_color_spaces_free
                                    procedures were removed.

              src/gslib.c           Removed use of the gs_current_Device*_space and
                                    gs_image_t_init_gray procedures.

              src/gspcolor.c        Removed reference to the orig_cspace_index field,
                                    which is no longer part of the library's graphic
                                    state.

              src/gsptype1.c        Eliminated use of the gs_cspace_DeviceGray procedure,
                                    and insured that a color space is set as the current
                                    color space before it is used.

              src/gsstate.c         Removed code that maintained the device_color_spaces
                                    field (color space substitution), which is no longer
                                    in the library's graphic state.

              src/gxclrast.c        Removed use of the gs_cspace_Device* procedures.

              src/gximage3x.c       Removed use of the gs_image_t_init_gray procedure.

              src/gximage2.c        Modified color space handling for ImageType 2 images.
                                    Note that there was and still is a problem with the
                                    handling of transformations in this code.

              src/gxistate.h        Removed the shared field of the imager state, all
                                    associated structures and prototypes, and modified
                                    the affected GC macros. The gx_device_color_spaces_t
                                    structure was previously used in the graphic library's
                                    state as well, but that use has been eliminated.

              src/gzstate.h         Removed the the device_color_spaces field, and modified
                                    the requisite GC macros

              src/idparam.c         Modified dict_float_array_check_param to handle
                                    packed (short or mixed) arrays.

              src/igstate.h         Added the use_cie_color field. This is a mirror for
                                    the UseCIEColor parameter of the page device, used
                                    because the currentpagedevice operator is potentially
                                    expensive.

              src/iimage.h          Modified to restrict the interpreter to just the
                                    dictionary form of the image and imagemask operator.
                                    This removes the zimage_opaque_setup, zimage_data_setup,
                                    and zimage_multiple prototypes, and moves the
                                    image_params structure and the image1_setup
                                    prototypes to this file (from iimage2.h).

              src/iimage2.h         Moved everything except the prototype for
                                    process_non_source_image to iimage.h.

              src/iutil.c           Added process_float_array procedure, to allow packed
                                    (short, mixed) arrays of numbers to be handled.

              src/iutil.h           Added prototype for the process_float_array procedure.

              src/zcolor.c          Removed:
                                      zcurrentgray, zcurrentrgbcolor,
                                      setgray, setrgbcolor
                                    Moved (from zcolor2.c):
                                      zcurrentcolor, zcurrentcolorspace,
                                      zsetcolor, zsetcolorspace
                                    Added:
                                      zgetuseciecolor   queries the use_cie_color field
                                                        in the interpreter state
                                      zsetdevcspace     sets a DeviceGray, DeviceRGB, or
                                                        DeviceCMYK color space

              src/zcolor1.c         Removed zcurrentcmykcolor, zsetcmykcolor, and
                                    zcolorimage.

              src/zcolor2.c         Removed everything in prior version. Added
                                    zusealternate, to test if an alternate color space
                                    is being used (for a Separation, DeviceN, or ICCBased
                                    color space), or if a base color space is in use
                                    (for an Indexed or a Pattern color space that uses
                                    a base space).

              src/zdpnext.c         Replace the alphaimage operator with .alphaimage,
                                    which has the semantics of the dictionary form of
                                    the image operator.

              src/zgstate.c         Modified the initgraphics operator to set the
                                    colorspace.array field to a legitimate color space
                                    (previously it was set to a null object). Also
                                    inserted code to initialize the use_cie_color field
                                    to false.

              src/zimage.c          Removed the traditional-form image and imagemask
                                    operators (zimage and zimagemask), and moved the
                                    dictionary form of these operators to this file
                                    from zimage2.c. Also, added the has_alpha parameter
                                    to the data_image_params and pixel_image_params
                                    procedures, to support the .alphaimage operator.

              src/zimage2.c         Moved everything except the process_non_source_image
                                    procedure to zimage.c.

              src/zimage3.c         Updated calls to data_image_params and
                                    pixel_image_params to add has_alpha parameter.

              src/zmisc3.c          Removed .setsubstitutecolorspace operator.

              src/zpcolor.c         Modified .setpatternspace to handle a packed (short,
                                    mixed) array operand.

              src/zshade.c          Modified build_mesh_shading to handle a packed (short,
                                    mixed) DataSource array operand.

              src/ztrans.c          Modified calls to data_image_params and
                                    pixel_image_params to add has_alpha operand.

              src/watclib.mak       Removed reference to the hsblib.dev, which no longer
                                    exists and which, for some unknown reason, was directly
                                    included in this makefile. Does anyone still use this
                                    file?

              src/int.mak           Removed hsb.dev and the zimage2_l2 operators, added
                                    zcolor3.c, updated various dependency lists.

              src/lib.mak           Removed hsblib.dev and gscssub.[ch], updated various
                                    dependency lists. Note that this file has not yet
                                    been modified to always compile with Level 3 support.

            * gscsepr.c [1.7] (+3 -3):
            Changed a couple of references to device_n.params to separation.params.

            * gxcmap.c [1.12] (+3 -3):
            Correction to the last commit

    Thu May  9 07:00:00 2002 GMT        August Daniel Coby    dan@meerkat

            * vdtrace.c [1.2] (+1 -2), lib.mak [1.12] (+2 -2), gslib.c [1.3] (+15 -7):
            Changes required to get the GS lib to build.

            * zcssepr.c [1.4] (+22 -40), zcsdevn.c [1.7] (+6 -6), zcolor2.c [1.6] (+1 -28),

            gscdevn.h [1.6] (+19 -14), gscdevn.c [1.8] (+61 -25), gdevpdfc.c [1.3] (+2 -2):
            1. Revised version of the Separation color space implementation.  The /None
            case now works.  The "normal" case is now implemented as part of the separation
            color space instead of using the DeviceN logic.
            2. The Separation and DeviceN color space handler for getting the alternate
            color space now return NULL if the alternate color space is not being used.
            (As pere request from ORIMP.)
            3. The DeviceN color space had a problem with an ICC alternate space. Corrected.

            * zht2.c [1.5] (+2 -4):
            Removed unused variables.

            * gsbitops.h [1.3] (+17 -6):
            Added casts to reduce warning casting warnings.

    Thu Apr 25 04:00:00 2002 GMT        August Daniel Coby    dan@meerkat

            * gxiscale.c [1.6] (+2 -2):
            The parameters to a call to remap_concrete_color were in the wrong order.

            * gdevxcf.c [1.7] (+65 -22):
            Apply RGB->device and CMYK->device profiles only in DeviceN color model;
            in DeviceRGB and DeviceCMYK color models, the mapping is defined by
            the PostScript spec. Also map DeviceGray colorspace to CMYK.

    Tue Apr 23 08:00:00 2002 GMT        Raph Levine    raph@meerkat

            * gdevxcf.c [1.6] (+117 -8), gdevdflt.c [1.9] (+9 -6):
            Makes xcfcmyk device agile in ProcessColorModel. Changes "expert
            system" logic slightly so that is_like_DeviceRGB is only called
            when filling in the default is needed.

    Tue Apr 23 06:00:00 2002 GMT        August Daniel Coby    dan@meerkat

            * lib.mak [1.11] (+3 -2), int.mak [1.4] (+3 -2):
            These two files should have been included in the previous commit.

            * zfsample.c [1.2] (+22 -21), zcssepr.c [1.3] (+79 -94),
            zcsdevn.c [1.6] (+34 -176), gxdevice.h [1.8] (+6 -1), gxcmap.h [1.8] (+7 -1),

            gscsepr.c [1.5] (+84 -176), gscdevn.h [1.5] (+9 -6), gscdevn.c [1.7] (+25 -19):
            Changed the separation color space to use common logic with the DeviceN
            color space.  This commit also brings the DeviceN code up to date.  This
            includes the function sampling logic in zfsample.c.  This code handles the
            /All case and the normal separation case.  The /None case is not handled
            correctly.  All components are erased (zeroed) when /None is selected.

            * gscspace.h [1.6] (+3 -1):
            I was over zealous in cleaning up this file.  Restored defintion of
            gx_indexed_map.

            devs.mak [1.10] (+2 -2):
            These changes are required to initialize the "display" device to work
            with the DeviceN code.  This involves setting up the correct color_info
            structure for the device and the DeviceN related procs.

    Tue Apr 16 07:00:00 2002 GMT        Henry Stiles    henrys@meerkat

            * gxdevcli.h [1.9] (+3 -12):
            removes duplicate dci_std_color() macro definition.

    Tue Apr 16 05:00:00 2002 GMT        August Daniel Coby    dan@meerkat

            * gdevdevn.c [1.8] (+2 -3):
            Some more corrections to the initialization of the spotrgb and spotcmyk
            device structures.  Apologies to Henry.  I misunderstood the results from
            the cvs merge.  Henry did not mangle the bpp, etc. in the previous commit.

    Tue Apr 16 04:00:00 2002 GMT        August Daniel Coby    dan@meerkat

            * gxdither.h [1.4] (+10 -10):
            Added prototype for function gx_render_device_DeviceN.
            Removed some unused macro definitions.

            * lib.mak [1.10] (+2 -2), gxcmap.c [1.9] (+49 -31):
            1.  Added included of string_.h.  This resolves some undefined function
            prototypes.
            2.  Corrected handling of transfer functions and halftoning.  (Transfer
            functions were not being applied if halftoning was being done.)
            3.  Finished the half tone code for DeviceN color model devices.
            4.  Some misc code clean up to remove misc warning messages.

    Tue Apr 16 03:00:00 2002 GMT        August Daniel Coby    dan@meerkat

            * gsht1.c [1.5] (+2 -2):
            We were not allocating a half tone cache for the "gray" component.

            * gdevdevn.c [1.7] (+22 -15):
            1.  Convert the spotcmyk device back to a half toned (1 bit per pixel per
            component) device.  This had been changed by Henry is the last commit.
            2.  Corrected the gray color space to cmyk color model handler.  This was
            corrupting the cmykspot colors.
            3.  Corrected a couple of problems in the spotcmyk device.  (Garbage data
            in the last half of byte if a line had an odd number of pixels.  Bad bps
            and planes in the pcx header - the cmyk pcx output file is really a 4 bit
            device with a color mapping table.)

            * gstype42.c [1.4] (+4 -2):
            conditional compile (hack) to prevent freeing glyph data when library is
            built with pcl.  This is a long standing issue supported by a thousand
            lines of email and 0 lines of code.

    Mon Apr 15 23:00:00 2002 GMT        Henry Stiles    henrys@meerkat

            - pcl color mapper support.
            - modification for pcl build.

            * msvccmd.mak [1.3] (+4 -2):
            Create a separate WARNOPT parameter for specifying the warning message
            level.  This allows the message level to be specified from the command
            line.

    Tue Apr  9 00:00:00 2002 GMT        August Daniel Coby    dan@meerkat

            * gxdevndi.c [1.7] (+11 -6):
            Fixed a debug printout which needed to be updated for a variable number of

    Tue Apr  2 08:00:00 2002 GMT        Raph Levine    raph@meerkat

            * gdevxcf.c [1.4] (+153 -43):
            Adds ICC profile paths to RGB->Color Model and CMYK->Color Model
            transforms in xcfcmyk device. Use ProfileRgb (3->N) and ProfileCmyk
            (4->N) device parameters to install ICC transforms.

            Changes to enable the use of the clist device (banding) with the DeviceN
            colorspaces and devices.  This is still missing the clist commands for
            transfer functions and the DeviceN component map.

    Wed Mar 27 01:00:00 2002 GMT        Raph Levine    raph@meerkat

            * gdevxcf.c [1.3] (+131 -6), devs.mak [1.9] (+6 -3):
            Adds some ICC color profile ability to the xcf device, for testing

            * gshtx.h [1.4] (+1 -3):
            Removed sepr_name parameter from function prototypes.  This change
            goes with an earlier change to gshtx.c.

    Tue Mar 19 19:00:00 2002 GMT        August Daniel Coby    dan@meerkat

            * gshtx.c [1.6] (+1 -13):
            Changes requested by henry.  The separation name has been removed
            from the calling sequence for gs_ht_set_threshold_comp and
            gs_ht_set_mask_comp.  (These routines are used by PCL.)

    Mon Mar 18 07:00:00 2002 GMT        Henry Stiles    henrys@meerkat

            gdevcmap.c [1.6] (+16 -16):
            operand changes and misc. fixes for compiling pcl.  I used pcl because
            it was not clear how even to compile the gslib target.  With
            implementations for gs_ht_set_mask_comp() and
            gs_ht_set_threshold_comp() it will be possible to build pcl and verify
            the changes to these files from pcl.

    Mon Mar 18 05:00:00 2002 GMT        Henry Stiles    henrys@meerkat

            * gdevpdfg.c [1.5] (+4 -3):
            pdf_update_transfer() was not returning a value resulting in the
            previously encountered pdf problems.  It now retuns 0 and prints a

            compile fixes for pdfwrite and miscellaneous post merge problems
            fixed.  Running the interpreter with pdfwrite fails upon the first
            graphics painting operation returning an uninitialized error code, so
            this will need more work.

            * gxcindex.h [1.4] (+12 -10):
            The value of gx_no_color_index was being forced to be a 'long' value
            instead of matching the size of gx_color_index.  Change it to use gx_color_index
            as its type.  (May create a problem on Irix 5.2.)

            * gxcht.c [1.9] (+46 -48):
            Now the halftoning will work with almost any number of components.

    Wed Feb 27 02:00:00 2002 GMT        August Daniel Coby    dan@meerkat

            * gxcht.c [1.8] (+6 -5):
            THis fix corrects the halftone hander which is used to handle more than four
            components.  It ws not correctly handling the mixture of a fully saturated
            component and some halftoned components.  (Worked with zero value components.)

    Thu Feb 21 07:00:00 2002 GMT        August Daniel Coby    dan@meerkat

            * gxcht.c [1.7] (+13 -6):
            This corrects a problem with some magenta coloring around the muzzle of
            the tiger.eps file when using the pcxcmyk device.

            Note:  There is still some stuff to check.  This fix primarily uses
            special code for 1 bit cmyk colors (same as previous versions of GS).
            The non 1 bit routines should produce the same result do not.

    Thu Feb 21 04:00:00 2002 GMT        August Daniel Coby    dan@meerkat

            * gxcht.c [1.6] (+16 -38):
            Corrected problems in set_ht_colors_le_4 which was preventing it from
            compiling.  This is the halftoner for non single bit 4 or less components.

    Tue Feb 19 05:00:00 2002 GMT        Henry Stiles    henrys@meerkat

            * unix-gcc.mak [1.5] (+3 -8), gdevm48.c [1.4] (+2 -2):
            The pixel size was incorrectly set to 3 instead of six (jan).  Adds
            CPPFLAG define for the long long so it works properly with raph's xcf
            device.

    Tue Feb 19 05:00:00 2002 GMT        August Daniel Coby    dan@meerkat

            * gxcht.c [1.5] (+13 -14):
            Corrects a problem with an unknown error being returned in 'fill' when
            drawing tiger.ps using the pcxcmyk device.  Some of the color halfoning
            code is disabled because it is not compatible with the devicen device
            color mapping routines.  This fix corrects some of these problems.

            Note:  There are still more problems in this module related to the DeviceN
            implementation.  There are many places that that assume 3 or 4 colors
            only.

            * gdevm40.c [1.4] (+2 -2):
            Matching change to the change in gdevm48.c.  Changed a hard coded value
            of 3 for the pixel size to PIXEL_SIZE.  The 3 was a holdover from code
            copied from gdevm24.c.  Note: gdevm56.c and gdevm64.c are already
            correct.

    Fri Feb 15 06:00:00 2002 GMT        August Daniel Coby    dan@meerkat

            * gxdevcli.h [1.6] (+1 -13):
            Removed unnecessary and incorrect dci_deviceN macros that had been
            previously inserted.  As per request for Jan. S.

    Tue Feb 12 18:00:00 2002 GMT        Raph Levine    raph@meerkat

            * gdevxcf.c [1.1] (+1047 -0), devs.mak [1.6] (+12 -1):
            Adds an "xcf" device, which generates Gimp XCF file format, with
            additional channels for DeviceN separations.

            This commit enables halftoning.  Note:  The module gsdevndi.c contains
            the interface for setting up a halftone.

            Also corrects a problem with purple tigers caused by changes in gdevdsp.c
            in the last commit.

            This commit creates a halftone array in the imager state which contains
            one halftone (and transfer function) for each device colorant.

            more color operand fixes from the MSVC build as reported by Dan.  This
            snapshot compiles with msvc ver 6.0.

            missed color encoding operand changes.  These devices were not
            dependencies in the unix gcc build.  Adds epson device (back) to gcc
            makefile.  It is unclear why the epson devices were removed.

            This is a first pass at implementing the transfer functions in the DeviceN

            removed shortly.

            * gs_init.ps [1.8] (+14 -3):
            Modified File: (jan)

              lib/gs_init.ps    Modified .sethireshalftone to ignore components
                                not present in a device when determining if gamma
                                correction is required due to (imputed) dot-gain.
                                This corrects a problem with certain three-color
                                devices whose nonexistant gray component was
                                inappropriately causing gamma correction to be
                                applied.

            gs_icc.ps [1.6] (+7 -3), gs_cspace.ps [1.4] (+27 -1):
            Modified Files: (jan)

              lib/gs_cspace.ps
                Added _setcolorspace_nosub, a variation of the setcolorspace operation that
                avoids color space substitution. This is required for ICCBased color spaces,
                as they may be used to substitute for a device-specific color space, but
                use that same device-specific color space as an alternative space. If the
                alternative space was used (or even if it wasn't, in the prior code), an
                infinite loop would result (the eventual error is execstackoverflow).

              lib/gs_icc.ps
                Modified the cs_install routine for ICCBased color spaces to use the new
                _setcolorspace_nosub procedure.

              lib/pdf_draw.ps
                Removed the color substitution scheme used by resolvecolorspace. This has
                been superseded by the PostScript-based scheme.

              lib/pdf_main.ps
                Implemented color space substitution using PostScript's method. This works
                for all color spaces and, with the above noted modifications to
                gs_cspace.ps and gs_icc.ps, avoids infinite-loop problems. The
                earlier code did not implement color space substitution for
                DeviceCMYK (the code was just missing) and in rare cases could
                suffer from infinite loops.

              src/zcolor.c
                Correct a typo: the .setdevcspace operator was included twice in the
                zcolor_op_defs array.

            The following should be prominently posted in full view of all
            software engineers:

              ***Do not use caches to hold unreplaceable data***

            Failure to follow that rule of good programming is the heart of the
            problem with FTS panel 245-04 (file 245-01.ps).

            The immediate cause of the problem is the optimization put in the
            setcolorspace code to avoid repeatedly setting the same color space.
            The steps that lead to the error are the following:

              1. The job sets a CIEBasedABC color space as the current color
                 space. The white and black point information from the color
                 space dictionary is combined with the white and black point
                 information in the color rendering dictionary to sample the
                 TransformPQR procedures in that dictionary. The resulting
                 data is placed in the joint CIE cache. All of this activity
                 ends with an execution of the internal operator cie_tpqr_finish
                 (zcrd.c). This operator has two side-effects:

                     The TransformPQR data structure in the cie_render structure
                     of the current state is set to TransformPQR_from_cache, which
                     indicates that the PQR phase of the CIE color mapping (the
                     white point point adjustment) is to be done via the joint CIE
                     cache.

                     The gs_cie_cs_complete procedure is invoked with the "init"
                     argument set to false, indicating that no further
                     initialization is required for the joint CIE caches. This
                     causes the status flag in those caches to be set to
                     CIE_JC_STATUS_INITED, indicating that the caches are ready
                     to use.

              2. The job calls gsave. Since the joint CIE caches can be shared by
                 multiple graphic states, the cache reference count is incremented.

              3. The job sets a pattern color space, whose base color space is the
                 current (CIEBasedABC) color space.

                 The PostScript interpreter in Ghostscript uses the convention that
                 a base or alternative color space will always be set as the current
                 color space immediately before the enclosing color space is set.
                 The cs_install procedure for the pattern color space
                 (lib/gs_patrn.ps) invokes setcolorspace on the base space. Because
                 this is already the current color space, nothing happens.

              4. Immediately afterwards, the cs_install procedure invokes the
                 .setpatternspace operator on the enclosing pattern color space.
                 Through a couple of layers, this will invoke the "install_cspace"
                 method for pattern color spaces, the gx_install_Pattern
                 (gspcolor.c). This will in turn invoke the "install_cspace" method
                 for the base color space, in this case gx_install_CIE.

              5. Through a few additional layers, gx_install_CIE will also call
                 gs_cie_cs_complete (see (1) above), but this time the "init"
                 variable will be set to true, indicating that additional
                 initialization is required.

                 gs_cie_cs_complete will invoke gx_currentciecaches, whose purpose
                 is to make sure that new copies of the joint CIE cache is created
                 when necessary. Since the reference count on the existing cache is
                 larger than 1 (see (2) above), a unique copy of the cache is created
                 and is marked as invalid.

              6. Subsequently, when drawing is attempted in the base color (the
                 pattern has PaintType 2), the code will note that the cache is
                 not yet valid and invoke cie_joint_caches_init (gscie.c). This
                 routine can do nothing, however, because the TransformPQR structure
                 for the cie_render structure in the graphic state is set to
                 TransformPQR_from_cache, indicating that the only data available
                 for the TransformPQR procedure is in the (now invalidated) cache.

                 As a fall-back, the CIE color is mapped to RGB by setting all
                 components to 0, which yields the black output.

            The proper fix for this problem is re-designing both the CIE color space
            and the color rendering structures so that they retain enough information
            to regenerate the joint CIE cache when necessary. Since that is a big
            change, the attached modifications take the more modest approach of adding
            a "forcesetcolorspace" operator, which will set a color space even if it
            is identical to the current color space.

            Also included in the set of changes is a minor modification to gs_rectfill
            (gsdps1.c) that suppresses direct access to the device's fill_rectangle
            procedure if both overprint and overprint mode are true. Since
            overprintmode must be applied prior to halftoning, the code must be forced
            through one of the higher-level methods which include the pre-halftoned
            device color information.

            Modified files:

              lib/gs_cspace.ps
                Added the _setcolorspace procedure, which accepts both a boolean and
                a color space dictionary. If the boolean is true, the color space
                will not be set if it is the same as the current color space (via a
                conservative evaluation).

                The setcolorspace pseudo-operator now invokes _setcolorspace with the
                boolean operand set to true. A new operator, forcesetcolorspace,
                invokes _setcolorspace with boolean set to false.

              lib/gs_devn.ps
              lib/gs_icc.ps
              lib/gs_indxd.ps
              lib/gs_patrn.ps
              lib/gs_sepr.ps
                Replaced setcolorspace with forcesetcolorspace when setting a base or
                alternative color space. This is necessary due to some problems in the
                handling of the the joint CIE cache in the graphic library.

              src/gsdps1.c
                Modify gs_rectfill to suppress direct access of a device's
                fill_rectangle method if both overprint and overprint mode are set
                to true. This is required to make sure the overprint compositor has
                access to pre-halftoned device color information with which to
                implement overprint mode.

            * gs_ll3.ps [1.4] (+5 -1):
            Modified Files:

              lib/gs_ll3.ps
                Added code to create the setoverprintmode and currentoverprintmode
                operators.

              src/gconf.c
                Add the gx_compositor_list array, to list the set of compositor
                types compiled into the system. Also provided the gs_find_compositor
                procedure, to locate a compositor method vector based on its
                type identifier.

              src/gdevdgbr.c
                Fixed several bugs in gx_get_bits_copy, for cases in which the
                transfer of output data involves a skew (bit shift) but no color
                conversion (a case that is apparently used only by the overprint
                facility). This case uses the copy_mono method for the 1-bit
                memory device. The invocation of this method had two problems:

                  1. The temporary device created for the transfer had uninitialized
                     width and height fields. Because copy_mono will invoke the
                     fit_copy macro, these fields must be set to reasonable values.

                  2. The width passed to copy_mono must be bit-width, as the
                     method for a depth == 1 device is used. Previously, the
                     pixel width was used.

              src/gdevx.c
                Fixed a problem in x_copy_image. If the image passed to this routine
                contains more than one pixel, the colors_and and colors_or fields were
                not updated. Because these fields are only used for optimization, and
                properly updating them in this situation is potentially expensive,
                they are now just set to safe values (colors_and = 0;
                colors_or = (x_pixel)(-1)).

              src/genconf.c
                Added to "-comp" option to support construction of a list of
                compositors compiled into the system.

              src/gs.mak
                Added the SETCOMP and ADDCOMP macros, to provide access to the
                -comp option of genconf.c.

              src/gsalphac.c
                Exported the gs_composite_alpha_type structure, and added a compositor
                type identifier to this structure. Also modified the de-serialization
                (read) method for this size so that the data string provided be large
                enough but not necessarily exactly the right size, and to return the
                number of bytes actually read (or an error code).

              src/gscdefs.h
                Added a prototye for gs_find_compositor (see gconf.c above).

              src/gscolor.c
                Modified gx_set_device_color_1 to turn off overprint (and overprint
                mode).

              src/gsovc.c:
                1. Modified the de-serialization method (read) to return the number of
                   bytes actually read (or an error code).
                2. Renamed gs_overprint_type to be gs_composite_overprint_type, so as
                   to conform to the new convention for compositor names.
                3. For the overprint devices, set the get_xfont_procs, get_xfont_device,
                   and text_begin methods to use the corresponding default methods,
                   rather than the forwarding methods. Device-supported fonts are
                   incompatible with overprint, as the required low-level calls may
                   not be made. While the text_begin method is not itself a rendering
                   method, it does record an imaging device, and this device must
                   be the overprint device rather than the target device. If the
                   forwarding text_begin method is used, the recorded imaging device
                   would be the target device.
                4. Modified update_overprint_params to avoid use of the overprint
                   devices for cases in which overprint is true, but all color
                   components are to be drawn. Though the output is not changed, use
                   of the non-overprint device improves performance in this case.
                5. Modified the default overprint compositor creation method
                   (c_overprint_create_default_compositor) to ignore overprint
                   requests if the current color model has only a single component.
                   Overprinting can never have an effect in this situation, and
                   avoiding these cases also avoids difficulties with mask caching
                   devices (such as are used with the character cache).

              src/gsstate.c
                Modified gs_state_update_overprint to update the color model mapping
                procedures and unset the device color. Though updating the overprint
                status will never change the color model, the overprint devices
                require a special set of forwarding color model mapping procedures.

              src/gxclimag.c
                Implemented the clist_create_compositor procedure (the create_compositor
                method for the command list device).

              src/gxclpath.c
                Replaced the cmd_opv_put_params code (0xdf) with cmd_opv_extend. This
                code indicates that the subsequent byte should be read and interpreted
                as a command from the gx_cmd_ext_op enumeration. Currently, this
                enumeration has two elements, cmd_opv_ext_put_params (the put_params
                method) and cmd_opv_ext_create_compositor (the create_compositor
                method).

              src/gxclrast.c
                1. Made the code parsing changes required by the new cmp_opv_extend
                   code (see gxclpath.h above).
                2. Added the read_create_compositor procedure, to interpret the
                   cmd_opv_ext_create_compositor command.

              src/gxclutil.c
                Modified cmd_put_params for the new cmp_opv_extend/cmd_opv_ext_put_params
                coding techinque.

              src/gxcmap.c
                Modified gx_set_cmap_procs to handle devices that have no
                get_color_mapping_procs method (such as mask caching devices).

              src/gxcomp.h
                Added the comp_id field to the gs_composite_type_t structure. Also
                added macros for the alpha and overprint compositors (the only two
                compositors in the current system).

              src/gxoprect.c
                Fixed typo in pack_scanline_lt8: the source data pointer was not
                being advanced.

              src/gxoprect.h
                Fixed typo in RCS identifier comment.

              src/lib.mak
                1. Updated several dependency lists.
                2. Added code to generate the list of compiled compositors.

            * gs_setpd.ps [1.5] (+5 -2), gs_init.ps [1.5] (+8 -3):
            code set from ORIMP to enable overprint and overprint mode.

            New Files:

              src/gxoprect.c
              src/gxoprect.h
                These files provide the low-level code for the fill_rectangle method
                of the overprint compositor device. There are three such procedures,
                which are used in different circumstances:

                  gx_overprint_generic_fill_rectangle is always applicable, but is
                    very slow as it must decode and re-encode the color for each pixel.

                  gx_overprint_sep_fill_rectangle_1 is applicable to separable and
                    linear color encodings whose depth is a divisor of
                    8 * sizeof(mono_fill_chunk) = 32. This is always the
                    case if depth <= 8. The code used in this case is, once past a
                    large amount of setup, about as fast as can be achieved while
                    using get_bits_rectangle.

                  gx_overprint_sep_fill_rectangle_2 is applicable to all other
                    separable and linear color encodings (all of which will have
                    depth % 8 = 0). This uses a byte-wise method which is in principle
                    slower than what could be achieved with a chunk-wise method, but
                    is much easier to code in the general case (i.e.: for multiple
                    possible depths). It will likely be faster in practice.

            Modified Files:

              lib/gs_init.ps
              lib/gs_setpd.ps
                Modified erasepage (and several other bits of code that erase the
                page) to turn off overprint before filling the page. This is necessary
                to preserve the meaning of erasepage.

              src/gsbitops.c
              src/gsbitops.h
                Added the bits_fill_rectangle_masked procedure, a generalization of
                the bits_fill_rectangle procedure that allows for a component mask.
                Also generalized bits_fill_rectangle (and bits_fill_rectangle_masked)
                to support depth > 8, so long as
                (8 * sizeof(mono_fill_chunk)) % depth = 0.

                Currently, bits_fill_rectangle_masked is used only by the overprint
                compositor device, but it can also be used by devices that can
                directly implement overprint (such as the memory device).

              src/gscdevn.c
                Modified check_DeviceN_component_names to initialize the
                component_map.sep_type field of the imager state to SEP_OTHER.
                Previously this field was not set for DeviceN color spaces, which
                confused some of the overprint code.

              src/gsovrc.c
                Implemented the real overprint_fill_rectangle procedures. As part of
                this work, added the local procedure swap_color_index, that swaps
                bytes in a color index as required to work with byte-oriented bitmaps
                on little-endian devices (only if depth > 8).

                Also fixed a parity bug in the creation of the retain_mask.

              src/gsovrc.h
                Fixed typo (/* $Id$ */).

              src/gxdcconv.c
                Modified color_rgb_to_cmyk to work if the imager state pointer
                operand is a null pointer. Note that in this case full undercolor
                removal and black generation will be performed, which is consistent
                with other such conversions in the code that do not have access to
                the imager state, but differs from the mapping used if the imager
                state is available but has no blackgeneration or undercolor removal
                map.

              src/lib.mak
                Added the gxoprect.$(OBJ) target and included this as a dependency
                in LIB4s. Also updated some other dependency lists.

            Additional file modified (not for overprint but needed for release):

              src/gdevdflt.c
                Added code to select a reasonable default value for the decode_color
                method, as this method is used extensively by the generic overprint
                implementation routines. The modifications are just a first pass to
                allow us to test the overprint code; they are not intended as a
                final solution.

    Wed May 29 06:00:00 2002 GMT        Henry Stiles    henrys@meerkat

            * gs_setpd.ps [1.4] (+21 -4), gs_sepr.ps [1.2] (+2 -1),

            checkin for three separate code set releases from ORIMP, release
            notes follow in reverse chronological order.

            Notes:

             Modified files:

              gsstate.c
                Added code to ignore an error return from the create_compositor call
                in gs_state_update_overprint if the call was made to turn off
                overprint. This avoids errors for device configurations that do not
                (yet) support the create_compositor call, when running files that do
                not require overprint support.

              gsovrc.h
                Fixed a typo in a commment.

              gxclrast.c
                Fixed a re-entrancy problem in read_set_color_space that was introduced
                by the previous modification to this file.

              gsimage.c
                Added a comment concerning re-entrancy, and slightly modified another
                comment.

              gscspace.c
                Added some comments concerning re-entrancy.

            Notes:

            Modified Files:

              src/gsovrc.c
                Added full compositor device "plumbing". The overprint compositor
                now does all of the required device creation and setup work. The
                only piece still missing are implementations of the low-level
                rendering routines that actually implement overprint.

              src/gsptype1.c
              src/gsptype2.c
              src/gxcht.c
              src/gxdcolor.c
              src/gxdcolor.h
              src/gxht.c
              src/gxpcolor.h
                Added the method get_nonzero_comps to the gx_device_color_type_t
                structure (the gx_device_color methods). This method is used by
                the overprint code to determine which color component intensities
                have non-zero value, which must be known to implement overprint
                mode.

              src/gsovrc.h
              src/gscspace.c
                Changed the drawn_comps field of the gs_overprint_params_t
                structure from a byte array to a gx_color_index. This is a bit
                ugly, as the value is a bit map rather than an encoded color,
                but allows much simpler processing. (As in device colors, a
                gx_color_index is used because it is known to be large enough.

              src/lib.mak
                Updated dependency list for gsovrc.$(OBJ).

            Notes:

            New Files:

              src/gsovrc.c
                Implementation of the overprint compositor. For the moment, this is
                just a stub. This file will grow considerably in the next two releases.

              src/gsovrc.h
                Interface to the overprint compositor. This is in essentially final
                form, even though only a stub implementation of the compositor is
                available. This file also includes a lengthy comment describing when
                the compositor must be updated.

            Modified Files:

              lib/gs_ciecs2.ps
              lib/gs_ciecs3.ps
              lib/gs_cspace.ps
              lib/gs_devcs.ps
              lib/gs_devn.ps

              lib/gs_patrn.ps
              lib/gs_sepr.ps
                Incorporated an optimization of setcolorspace from the casper head.
                The optimization avoids setting the color space if it is the same as
                the current color space. gs_icc.ps also contains a fix for a bug
                in the handling of DataSources that are streams (rather than strings;
                Dan discovered and analyzed this bug).

                Note that this is a fairly complex optimization, and there were many
                problems with the head code that needed to be resolved. Among these
                were:

                  1. An invocation of setcolorspace should always set the default
                     color for the operand color space, even if that color space is
                     identical to the current color space.

                  2. If UseCIEColor is true, setcolorspace must be executed if
                     the operand color space involves device-specific color spaces.
                     This is because the Default{Gray,RGB,CMYK} instances of the
                     ColorSpace resource category may have changed.

                  3. When UseCIEColor is changed from true to false in setpagedevcie,
                     the implicit initgraphics invocation must perform a setcolorspace
                     operation, even if the current color space is DeviceGray. This
                     is necessary to ensure that the un-substituted DeviceGray color
                     space is set as the current color space.

              lib/gs_init.ps
                In /showpage, replace the sequence "erasepage ... initgraphics" with
                "initgraphics 1 setcolor .fillpage 0 setcolor". This has the desired
                effect, and avoids two unnecessay invocations of setcolorspace.

              lib/gs_setpd.ps
                1. Modified the currentpagedevice pseudo-operator for cases in which
                   the stored page device must be copied. Previously, the new copy
                   was allocated in the current VM mode, which could cause
                   invalidaccess errors if currentpagedevice was invoked while in
                   global VM mode and composite objects stored in the page device
                   dictionary were in local VM (this problem is present in the PS3
                   FTS). The new code will allocate the copy in the save VM as the
                   original dictionary.

                2. In setpagedevice, added code to set current color space to
                   something other than DeviceGray if modification of the page device
                   will set UseCIEColor to false. This is necessary for the
                   setcolorspace optimization to function properly (see above).

                3. In the .postinstall pseudo-operator, replaced "erasepage initgraphics"
                   with "initgraphics 1 setcolor .fillpage 0 setcolor". This avoids
                   two unnecessary invocations of setcolorspace.

              src/gdevp14.c
                Added the pdf14_create_compositor method. This method will check if
                the compositor to be created is the overprint compositor. If so,
                the request to create the compositor will simply be ignored, as
                the gs_pdf14_device and its associated marking device must implement
                overprint directly.

              src/gscdevn.c
                1. Removed the equality check method.

                2. Added the set_overprint method for DeviceN color spaces.

              src/gscolor2.c
                1. Removed the equality check method.

                2. Added the set_overprint method for Indexed color spaces.

              src/gscpixel.c
                1. Removed the equality check method.

                2. Added the set_overprint method for DevicePixel color spaces.

              src/gscscie.c
                1. Removed the equality check method.

                2. Added the set_overprint method for CIEBased color spaces.

              src/gscsepr.c
                1. Removed the equality check method.

                2. Added the set_overprint method for Separation color spaces.

                3. Moved the gs_{set|current}overprint[mode] procedures to gsstate.c.

              src/gscsepr.h
                Moved prototypes for the gs_{set|current}overprint[mode] procedures
                to gsstate.h.

              src/gscspace.c
                1. Removed the color space equality check methods for the device-
                   specific color spaces.

                2. Added the basic set_overprint procedures, to provide color-space
                   specific setting of the overprint compositor.

                3. Modified the gs_cspace_{build|init}_Device{Gray|RGB|CMYK}
                   procedures to use the same identifier for all instances of
                   the parameterless color spaces (i.e.: all DeviceGray instances
                   will have the same id, as will all DeviceRGB instances, but the
                   id for any DeviceGray will differ from the id for a DeviceRGB
                   instance). This enables an optimization in the gs_setcolorspace
                   routine that had been lost in the previous code modification.

              src/gscspace.h
                Removed prototype for the gs_color_space_equal procedure.

              src/gsicc.c
                1. Removed the equality check method.

                2. Added the set_overprint method for ICCBased color spaces.

              src/gslib.c
                Modified test9 to explicitly reset the current color space; this
                is no longer done by gs_initgraphics.

              src/gspcolor.c
                Added set_overprint method for pattern color spaces, removed the
                equality check method.

              src/gsstate.c
                1. Added code to update the overprint compositor when the current
                   color space, current device, overprint, or overprint mode
                   settings change. Included in this change is code in gs_grestore_only
                   that updates the overprint compositor as part of the grestore
                   operation when this is required.

                2. Moved the gs_{set|current}overprint[mode] procedures to this file
                   from gscsepr.c. This is more convenient for the new code, and
                   gscsepr.c was never a particularly appropriate place for these
                   routines.

                3. Modified gs_initgraphics to not reset the current color space or
                   current color. For PostScript this must now be done in the
                   PostScript code to properly handle color space substitution.
                   Other clients that use this procedure (the XL interpreter is the
                   only one (aside from gslib.c)) can easily reset these parameters
                   as well.

              src/gsstate.h
                Moved prototypes for the gs_{set|current}overprint[mode] procedures
                here from gscsepr.h.

              src/gxccache.c
                Modified gx_image_cached_char to just return if the current color
                is a pure gx_no_color_index (transparent).

              src/gxcspace.h
                1. Removed the equality check method.

                2. Added the set_overprint method.

              src/gxipixel.c
                Modified the gx_image_enum_begin to allow the Decode array for
                imagemasks to have any two distinct numbers, rather than just 0 and
                1. This matches the behavior of all Adobe systems (though not the
                documentation), and avoids some spurious failures when running the
                FTS.

              src/gxpcmap.c
                Modified pattern_accum_copy_mono to just return if both the foreground
                and background colors are gx_no_color_index (transparent). If this is
                not done, the mask device's copy_mono procedure may generate an
                error when invoked (this is true for mem_mono_copy_mono).

              src/iutil.c
                Modified obj_eq to consider two 0-length arrays to be equal,
                irrespective of their type and their pointers (the latter aren't
                meaningful if the array length is 0). This matches the PostScript
                documentation and the behavior of Adobe systems. It also fixes
                some spurious failures in the FTS.

              src/lib.mak
                Added an entry for gsovrc (the overprint compositor), and updated
                various dependency lists.

              src/zfdcte.c
                Modified the DCTEncode procedure (zDCTE) to allocate the
                jpeg_compress_data and subsidiary memory structures in current VM.
                Previously these structures were allocated in gs_default_memory,
                which does not support garbage collection. Since the structures
                were subject to garbage collection and relocation, chaos could
                and, in the case of FTS file 119-28.ps, did ensue.

                Note that these structure must be allocated immovable, which
                requires a considerable amount of overhead when using VM. A better
                approach would be to allocate them in gs_default_memory, and use
                a more sophisticated structure descriptor for the stream_DCT_state
                structure (st_DCT_state).

              src/zgstate.c
                Slightly simplified zinitgraphics, and updated a comment in this
                procedure.

              src/zmisc.c
                Modified realtime operator to set a zero point at boot time. This
                avoids an annoying delay in running FTS panel 211-01 (206-01.ps).

              zpcolor.c
                Modified the pattern_paint_prepare procedure to use gs_setdevice_no_int
                rather than gx_set_device_only. It is not clear why the latter
                procedure was ever used in this location, and it is now important to
                use the former procedure so the overprint compositor may be properly
                updated.

            Overprint implementation (Jan Stoeckenius)

            This is a preliminary code release for the overprint capability. The
            release does not contain the overprint facility itself; it consists
            entirely of modifications so that color space changes will occur in a
            predictable fashion.

            Files removed:

              src/gshsb.c
              src/gshsb.h
              src/gscssub.c
              src/gscssub.h
              src/zhsb.c

            Files added:

              lib/gs_cspace.ps      PostScript portion of the basic color space handling;
                                    see the extensive comment at the head of the file
                                    for information. Note that color space substitution
                                    and the hue-saturation-brightness (HSB) color space
                                    are now fully implemented in the PostScript code;
                                    the interpreter and the graphic library are no longer
                                    involved in or even aware of these features.

              lib/gs_devcs.ps       Implementation of the DeviceGray, DeviceRGB, and
                                    DeviceCMYK color spaces.

              lib/gs_ciecs2.ps      Implementation of the LangaugeLevel 2 CIEBased color
                                    spaces: CIEBasedA and CIEBasedABC.

              lib/gs_ciecs3.ps      Implementation of the LanguageLevel 3 CIEBased color
                                    spaces: CIEBasedDEF and CIEBasedDEFG

              lib/gs_devpxl.ps      Implementation of the DevicePixel color spaces

              lib/gs_indxd.ps       Implementation of the Indexed color space.

              lib/gs_sepr.ps        Implementaton of the Separation color space.

              lib/gs_devn.ps        Implementation of the DeviceN color space.

              lib/gs_patrn.ps       Implementation of the Pattern color space.

              lib/gs_img.ps         Implementation of the traditional (non-dictionary)
                                    form of the image and imagemask operators, and the
                                    colorimage operator (including the Next alphaimage
                                    facility). The interpreter now provides only the
                                    dictionary form of the image and imagemask operators,
                                    including a variation that provides alpha-channel
                                    support.

                                    Also modified the handling of color spaces for
                                    ImageType 2 images. This slightly changes the behavior
                                    of these images. If PixelCopy is defined to be true
                                    in the image dictionary but such a copy cannot be
                                    supported, an error will be generated. This is in
                                    agreement with Adobe's documentation, but differs
                                    from the earlier behavior.

              The code for Indexed, Separation, and DeviceN color spaces
              incorporates code, courtesy of Dan, that will invoke the lookup or
              tint transform procedure in the appropriate context if this is
              appropriate (if there is a lookup procedure for Indexed color spaces
              or the alternate color space is in use for Separation and DeviceN
              color spaces). Currently this is not done recursively (if an Indexed
              color space has a DeviceN base color space, for example), but that
              has not proven necessary in practice. If necessary, it can be added.

              src/zcolor3.c         Code to implement the .setuseciecolor operator. This
                                    operator is used only in the setpagedevice code, and
                                    makes certain that the use_cie_color field in the
                                    interpreter's graphic state mirrors the setting of
                                    the UseCIEColor page device parameter.

            Files modified:

              lib/gs_dpnxt.ps       Added PostScript implementation of the alphaimage
                                    operator. This uses the internal .alphaimage
                                    operator, which is a variation of the image
                                    operator that provide alpha-channel support.

              lib/gs_icc.ps         Rewritten to implement the ICCBased color space
                                    in the new scheme. See the comments in
                                    lib/gs_cspace.ps for information.

              lib/gs_init.ps        Modified to include gs_cspace.ps, gs_devcs.ps,
                                    and gs_img.ps, and to remove img_util_dict and
                                    .cspace_util_dict from userdict at the end of
                                    initialization.

              lib/gs_lev2.ps        All explicit color spaces removed (with one
                                    exception, and replaced by inclusion of gs_devpxl.ps,
                                    gs_ciecs2.ps, gs_indxd.ps, gs_sepr.ps, and
                                    gs_patrn.ps. The only remaining color space support
                                    feature is moving the setcolorspace and setcolor
                                    pseudo-operators, and the colorspacedict dictionary,
                                    to level2dict. This must be done here, as it is not
                                    known that level2dict exists when gs_cspace.ps is
                                    first run.

                                    Also removed all explicit image support. This is
                                    now handled by gs_img.ps (see above).

              lib/gs_ll3.ps         Removed the old support for color space substitution;
                                    this is now handled directly by the color space
                                    code (see the comments in gs_cspace.ps for
                                    information). Added inclusion of gs_ciecs3.ps and
                                    gs_devn.ps.

              lib/gs_setpd.ps       Added support for the .getuseciecolor and
                                    .setuseciecolor operators. This maintains a
                                    "mirror" of the UseCIEColor parameter in the
                                    graphic state, to allow fast access.

              src/gdevnfwd.c        In gx_forward_get_color_mapping_procs, added a check
                                    for the case of a target device which has no
                                    get_color_mapping_procs procedure. This led to a
                                    segmentation violation crash for FTS file 296-01.ps
                                    The fix may not be the correct one, as we are not
                                    certain why a device would lack this method.

              src/gdevp14.c         Replaced a use of the shared field in the graphic state
                                    with a color space allocated on the C-language stack.

              src/gdevpsdi.c        Replaced an instance of use of the gs_cspace_DeviceRGB
                                    procedure.

              src/gscolor.c         Removed gs_currentgray and gs_currentrgbcolor. Modified
                                    gs_setgray and gs_setrgbcolor to use gs_setcolorspace
                                    and gs_setcolor. This eliminates use of the
                                    gs_current_Device*_space routines.

              src/gscolor.h         Removed prototypes for gs_currentgray and
                                    gs_currentrgbcolor.

              src/gscolor1.c        Removed gs_currentcmykcolor. Modified gs_setcmykcolor
                                    to use gs_setgray and gs_setcolorspace.

              src/gscolor1.h        Removed prototype for gs_currentcmykcolor.

              src/gscolor2.c        Removed gs_currentcolorspace_index. Removed the color
                                    index tracking used as part of the color space
                                    substitution method.

              src/gscolor2.h        Removed prototype for gs_currentcolorspace_index.

              src/gscscie.c         Eliminated use of the gs_cspace_Device* routines.

              src/gscsepr.c         Fixed a pair of typos in revision 1.6 of the code.
                                    In gs_cspace_set_sepr_proc and
                                    gx_concretize_Separation, the code was still accessing
                                    pcspace->params.device_n when it wanted to access
                                    pcspace->params.separation. This caused a crash in
                                    FTS file 245-01.ps.

              src/gscspace.c        Removed gs_cspace_Device* procedures.

              src/gscspace.h        Removed prototypes for gs_cspace_Device* procedures.

              src/gsimage.c         Removed use of the gs_cspace_DeviceGray procedure.

              src/gsiparam.h        Removed the gs_image_t_int_{gray, rgb, cmyk} macros.

              src/gsistate.c        Updated code to reflect removal of the shared field in
                                    the imager state. As part of this, the
                                    rc_free_imager_shared and gx_device_color_spaces_free
                                    procedures were removed.

              src/gslib.c           Removed use of the gs_current_Device*_space and
                                    gs_image_t_init_gray procedures.

              src/gspcolor.c        Removed reference to the orig_cspace_index field,
                                    which is no longer part of the library's graphic
                                    state.

              src/gsptype1.c        Eliminated use of the gs_cspace_DeviceGray procedure,
                                    and insured that a color space is set as the current
                                    color space before it is used.

              src/gsstate.c         Removed code that maintained the device_color_spaces
                                    field (color space substitution), which is no longer
                                    in the library's graphic state.

              src/gxclrast.c        Removed use of the gs_cspace_Device* procedures.

              src/gximage3x.c       Removed use of the gs_image_t_init_gray procedure.

              src/gximage2.c        Modified color space handling for ImageType 2 images.
                                    Note that there was and still is a problem with the
                                    handling of transformations in this code.

              src/gxistate.h        Removed the shared field of the imager state, all
                                    associated structures and prototypes, and modified
                                    the affected GC macros. The gx_device_color_spaces_t
                                    structure was previously used in the graphic library's
                                    state as well, but that use has been eliminated.

              src/gzstate.h         Removed the the device_color_spaces field, and modified
                                    the requisite GC macros

              src/idparam.c         Modified dict_float_array_check_param to handle
                                    packed (short or mixed) arrays.

              src/igstate.h         Added the use_cie_color field. This is a mirror for
                                    the UseCIEColor parameter of the page device, used
                                    because the currentpagedevice operator is potentially
                                    expensive.

              src/iimage.h          Modified to restrict the interpreter to just the
                                    dictionary form of the image and imagemask operator.
                                    This removes the zimage_opaque_setup, zimage_data_setup,
                                    and zimage_multiple prototypes, and moves the
                                    image_params structure and the image1_setup
                                    prototypes to this file (from iimage2.h).

              src/iimage2.h         Moved everything except the prototype for
                                    process_non_source_image to iimage.h.

              src/iutil.c           Added process_float_array procedure, to allow packed
                                    (short, mixed) arrays of numbers to be handled.

              src/iutil.h           Added prototype for the process_float_array procedure.

              src/zcolor.c          Removed:
                                      zcurrentgray, zcurrentrgbcolor,
                                      setgray, setrgbcolor
                                    Moved (from zcolor2.c):
                                      zcurrentcolor, zcurrentcolorspace,
                                      zsetcolor, zsetcolorspace
                                    Added:
                                      zgetuseciecolor   queries the use_cie_color field
                                                        in the interpreter state
                                      zsetdevcspace     sets a DeviceGray, DeviceRGB, or
                                                        DeviceCMYK color space

              src/zcolor1.c         Removed zcurrentcmykcolor, zsetcmykcolor, and
                                    zcolorimage.

              src/zcolor2.c         Removed everything in prior version. Added
                                    zusealternate, to test if an alternate color space
                                    is being used (for a Separation, DeviceN, or ICCBased
                                    color space), or if a base color space is in use
                                    (for an Indexed or a Pattern color space that uses
                                    a base space).

              src/zdpnext.c         Replace the alphaimage operator with .alphaimage,
                                    which has the semantics of the dictionary form of
                                    the image operator.

              src/zgstate.c         Modified the initgraphics operator to set the
                                    colorspace.array field to a legitimate color space
                                    (previously it was set to a null object). Also
                                    inserted code to initialize the use_cie_color field
                                    to false.

              src/zimage.c          Removed the traditional-form image and imagemask
                                    operators (zimage and zimagemask), and moved the
                                    dictionary form of these operators to this file
                                    from zimage2.c. Also, added the has_alpha parameter
                                    to the data_image_params and pixel_image_params
                                    procedures, to support the .alphaimage operator.

              src/zimage2.c         Moved everything except the process_non_source_image
                                    procedure to zimage.c.

              src/zimage3.c         Updated calls to data_image_params and
                                    pixel_image_params to add has_alpha parameter.

              src/zmisc3.c          Removed .setsubstitutecolorspace operator.

              src/zpcolor.c         Modified .setpatternspace to handle a packed (short,
                                    mixed) array operand.

              src/zshade.c          Modified build_mesh_shading to handle a packed (short,
                                    mixed) DataSource array operand.

              src/ztrans.c          Modified calls to data_image_params and
                                    pixel_image_params to add has_alpha operand.

              src/watclib.mak       Removed reference to the hsblib.dev, which no longer
                                    exists and which, for some unknown reason, was directly
                                    included in this makefile. Does anyone still use this
                                    file?

              src/int.mak           Removed hsb.dev and the zimage2_l2 operators, added
                                    zcolor3.c, updated various dependency lists.

              src/lib.mak           Removed hsblib.dev and gscssub.[ch], updated various
                                    dependency lists. Note that this file has not yet
                                    been modified to always compile with Level 3 support.

# Version 7.22 (2002-08-06)

This release integrates the rewritten pdfwrite font copying code, fixing a large class of pdfwrite bugs involving incremental font updating. This project was completed before the DeviceN merge was ready, so this release (rather than 7.21 as previously stated) is the final checkpoint prior to the DeviceN merge.

Overall, pdfwrite is probably an improvement over previous releases, but there are still known issues. Testing of pdfwrite with real-world files is encouraged.

The following SourceForge bug numbers were open at the time of the last release: 405342, 407342, 414947, 414985, 423838, 427347, 432040, 434277, 446344, 446672, 453969, 458261, 458775, 458780, 459647, 465720, 465936, 468762, 474745, 482038, 484752, 484753, 485510, 487953, 493348, 495319, 498595, 505429, 508081, 509646, 510808, 511232, 513905, 514616, 517349, 521916, 526099, 526491, 530011, 530588, 533467, 535366, 535752, 535836, 538033, 539239, 542848, 543185, 546823, 551565, 552989, 554076, 555496, 557177, 558151, 558435, 559614, 560508, 562103, 563287, 565790, 567421, 567487, 567604, 567773, 569573, 570181, 570772, 571980, 572119, 573744, 576586, 576591, 578838, 578865, 580029, 580873, 581420, 582471, 583413, 584713, 584990, 586178, 586595, 589244, 590307, 590979, 591039, 591326.

The nightly regression tests show many changes. However, most of the non-pdf regressions are tiny changes resulting in comparing a debug build against a non-debug baseline. The rendering really shouldn't be different at all, so we're leaving these regressions open until we can fix the discrepancy. On the pdfwrite side, most of the regressions are actually improvements, but there are some known issues. Notably, the "same_font" function is incorrect, and deriving several fonts from a standard font, replacing Metrics or Metrics2 only, pdfwrite incorrectly merges them into a single font. This causes a regression with 093-01.ps and probably other test files.

## Drivers

    Fixes problems:
    	- When compiled for A4 default page size, the initial page size is
    now 595x842pts. The initial printer page size in tenths of an inch now uses
    floating point. This may cause problems with old compilers that do not allow
    floating point calculations in initializers for integers. Add some casts to
    suppress warnings with the MS compiler. Fixes SourceForge bug #535997,
    "ps2pdf produces incorrect A4 page size". (gdevbmpc.c [1.5]: 2002/07/18

## PDF writer

    Fixes problems:
    	- Fixes the last (?) major batch of problems in the new pdfwrite
    text code. We think this code is now good enough for general testing: search
    for PDTEXT in src/devs.mak for information on how to enable it.

## PDF Interpreter

    Fixes problems:
    	- When using -dUseCropBox, use an inherited CropBox. The previous
    fix would only use a CropBox on the page being displayed.
    (lib/pdf_main.ps [1.54]: 2002/07/18 10:46:06 ghostgum)
    	- If a 'stream' operator was followed by whitespace before the EOL,
    then the fileposition was not at the start of the data. Add logic to allow
    for this and also add a pdfformaterror if the EOL was a <cr> without a
    <lf>. Fixes SourceForge bug 567612 for Artifex customer #1.

    	- Avoid opstack overflow by explicit array construction, rather than
    unpacking and padding on the stack, for padding of glyphencoding array.
    Fixes SF bug #576651. (lib/gs_ttf.ps [1.16]: 2002/07/10 06:29:34 raph)
    	- Adobe renders marks outside the ImagingBBox and QuarkXPress relies
    on this. Maintain the ImagingBBox of the page device at the PostScript level
    independently from the device parameter. There is a slight incompatibility
    if programs that set the ImagingBBox incorrectly relied on this causing
    clipping, which is prohibited by the PLRM. Programs that wish to directly
    set the ImagingBBox device parameter can still do so from C or from PS using
    the .putdeviceprops GS private operator. Fixes SF bug 570829 for Artifex
    customer #411. (lib/gs_setpd.ps [1.12]: 2002/07/10 23:05:59 ray)

    	- The addition of the function sampling logic for DeviceN tint
    transforms (fix 474544) tripped over a bogus assumption in Adobe Procset for
    DuoTones generated by (at least) Photoshop. The assumption was that if the
    alternate color space of a DeviceN space was being used, that the procedure
    would run when 'setcolor' was executed and that the stack would be
    accessible during that procedure. This fixes several bug reports with
    '/stackunderflow in pop' errors including SF #549307, 576577 and 582385 for
    Artifex customers. Thanks to Dan Coby for the analysis and fix.

## Library

    Fixes problems:
    	- Fixes bugs in font copying (currently used only by the new
    pdfwrite text code): TrueType glyphs with multiple names in CharStrings only
    stored a single name; copied Encodings were initialized incorrectly to
    .notdef rather than GS_NO_GLYPH; some of the procedures of copied TrueType
    fonts weren't initialized correctly; 'seac' didn't copy the Encoding entries
    for the components. Also shares the known glyph names when possible, to
    reduce the load on the garbage collector. (gxfcopy.c [1.14],
    gxfcopy.h [1.6]: 2002/07/09 14:26:45 lpd)
    	- When compiled for A4 default page size, the initial page size is
    now 595x842pts. The initial printer page size in tenths of an inch now uses
    floating point. This may cause problems with old compilers that do not allow
    floating point calculations in initializers for integers. Add some casts to
    suppress warnings with the MS compiler. Fixes SourceForge bug #535997,

# Version 7.21 (2002-07-08)

This is a reasonably stable development snapshot, the last before the DeviceN work gets merged in. In particular, this version is probably the most stable pdfwrite version to date.

The following SourceForge bug numbers were open at the time of the last release: 405342, 407342, 414947, 414985, 415142, 423838, 427347, 432040, 434277, 446344, 446672, 453969, 458261, 458775, 458780, 459647, 462221, 465720, 465936, 468762, 474745, 482038, 484752, 484753, 485510, 487953, 493348, 495319, 498595, 503794, 505429, 506375, 508081, 509646, 510808, 511232, 513905, 514616, 517349, 521354, 521916, 522486, 524292, 526099, 526491, 528647, 529103, 529578, 530011, 530588, 533467, 535366, 535752, 535836, 535997, 536877, 538033, 538267, 539239, 542848, 543185, 546823, 549307, 551565, 552949, 552989, 554076, 555496, 557024, 557177, 558151, 558435, 559614, 560508, 562103, 563287, 565790, 567421, 567487, 567604, 567612, 567773, 569573, 570181, 570213, 570217, 570772, 570800, 570816, 570829, 571897, 571980, 572119, 573744, 574865, 576574, 576577, 576586, 576591, 576615, 576651.

All the regression tests run correctly, with the following exceptions: pdfwrite testing of 401-01.ps, which segfaults.

### Incompatible changes

- The file gs/lib/CIDFnmap used in Ghostscript 6.53 and 7.0x to map CIDFont resource is no longer supported. Now it is replaced with gs/lib/cidfmap. TrueType font substition to CIDFont is not implemented yet.

## Documentation

    Fixes problems:
    	- Changes the operation of AutoFilter{Gray,Color}Images to always
    use the lossless filter (normally FlateEncode), rather than using DCTEncode
    for 8-bit-per-component images at least 64x64 in size. While this isn't
    optimal, it fixes a long-standing problem that many users have complained
    about. Fixes SourceForge #450663. (doc/Ps2pdf.htm [1.41]: 2002/04/08
    21:21:23 lpd)
    	- The recently added reference to zcidtest.c had the correct text
    but an incorrect URL. (doc/Develop.htm [1.73]: 2002/04/09 02:03:22 lpd)
    	- the url for the guide to international paper sizes has changed.
    Thanks to Nelson Beebe for finding the update. (doc/Use.htm [1.52]:
    2002/04/14 01:08:14 giles)
    	- The new file md5main.c was not included in the catalog of source
    files. (doc/Develop.htm [1.74]: 2002/04/14 15:56:53 lpd)
    	- More compatibility to Adobe interpreters in 'eexec'. This is
    NON-BACKWARD-COMPATIBLE change. Now eexec skips all whitespaces at the
    beginning of input stream, except for PFBDecode output. Thanks to L. Peter
    Deutsch for participation. Source Forge bug "[ 428891 ] Undefined commands
    interpreting Postscri". (doc/Language.htm [1.49]: 2002/05/01 23:15:23 igor)
    	- pdfwrite relied on the PostScript interpreter to load and make
    available the known encodings and glyph sets identified in src/gsccode.h.
    With this change, pdfwrite can now be used without a PostScript interpreter,
    and with fonts that do not implement the known_encode callback.
    (doc/Develop.htm [1.78], doc/Psfiles.htm [1.32]: 2002/05/12 22:38:08 lpd)
    	- Fixes a typo in, and slightly improves, documentation for invoking
    cvs2hist as part of the release process. Fixes SourceForge #551275.
    (doc/Release.htm [1.61]: 2002/06/26 20:14:45 lpd)
    	- Fixes a typo in the reference to src/gdevpdte.c.
    (doc/Develop.htm [1.83]: 2002/06/27 00:50:23 lpd)
    	- Add the option -dUseCropBox to set the page size from the CropBox
    rather than the MediaBox. This is appropriate when using ghostscript to view
    PDF files or convert to bitmaps. It probably isn't appropriate for printing.
    Fixes SourceForge bugs #522486, "Wromg size EPS generated from PDF" and
    #538267 "Problems with Media Box in PDF and PS interpreter".

    Changes gs_cmap_t (internal representation of CMaps) to an abstract
    superclass with multiple implementations: standard Adobe CMapType 1,
    TrueType 16-bit cmap (Platform 3, Encoding 1, Format 4), and one-for-one.
    Adds the ability to designate a CMap as Unicode-based. Enhances pdfwrite so
    that composite fonts (including those based on TrueType Unicode fonts) with
    Unicode-based CMaps are embedded in the PDF file with the original text
    preserved and with an appropriate ToUnicode CMap, making the text searchable
    in Acrobat. (doc/Develop.htm [1.72]: 2002/04/08 21:02:44 lpd)

    Documents more clearly the fact that the ProcessColorModel parameter for

    Deletes "Vanilla" functions, which have not been used for a long time. They
    were originally created for implementing FunctionType 4 functions using a

    Refactors the pdfwrite driver so that none of the structures, and very few
    of the procedures, for handling text and fonts are visible to the main body
    of code, in preparation for a major rewrite of the text and font code.

    SF#559565 (doc/Make.htm [1.51]: 2002/06/24 06:20:25 jeong)

    Adds a complete rewrite of the font and text code in pdfwrite, based on
    copying fonts incrementally to stable memory rather than trying to deal with
    fonts being freed at unpredictable times. Should fix a large number of
    current SourceForge bugs when completed: however, the code is currently in
    pre-alpha state and is not usable on any realistic input. The API is
    compatible with the previous pdfwrite text code; the choice of which set to
    use is controlled by a single, documented line in src/devs.mak.

## Procedures

    Fixes problems:
    	- gscdef.c must contain a definition for GS_PRODUCT that matches the
    definition used by the baseline. run_nightly now sets GS_PRODUCT to "AFPL
    Ghostscript" correctly regardless of it's setting in the repository.
    (toolbin/tests/run_nightly [1.4]: 2002/04/09 01:25:26 jack)
    	- gscheck_pdfwrite.py was modeled after run_regression instead of
    check_*.py. This corrects the script so that it follows the testing
    conventions and also adds gscheck_all.py which will run every gscheck_*.py
    test (of which currently there is only one).
    (toolbin/tests/gscheck_all.py [1.1],
    toolbin/tests/gscheck_pdfwrite.py [1.2], toolbin/tests/gstestgs.py [1.7]:
    2002/04/09 21:45:33 jack)
    	- Fix for #540871. Clean up compiler warnings in zfsample.c. Note:
    The addition of two include files in zfsample.c forces a change in
    dependencies in int.mak. (int.mak [1.70]: 2002/04/11 02:18:14 dan)
    	- Indexed color spaces weren't implemented for ShadingType 4-7
    shadings. (lib.mak [1.73]: 2002/04/14 04:30:47 lpd)
    	- Options specified in gsconf.py were not being used correctly by
    all scripts. run_regression and revert_baseline were both broken in this
    respect. (toolbin/tests/gstestgs.py [1.8],
    toolbin/tests/revert_baseline [1.5], toolbin/tests/run_regression [1.4]:
    2002/04/16 21:06:20 jack)
    	- missing space bofore the gsoptions are passed.
    (toolbin/tests/gstestgs.py [1.9]: 2002/04/16 21:22:25 jack)
    	- make symlinks to equivalent manpages with relative rather than
    absolute paths to facilitate moving the directory to another location.
    Closes SourceForge Bug #416131. (unixinst.mak [1.25]: 2002/04/18 01:53:36
    giles)
    	- the uniprint driver wasn't being included due to a typo.
    (os2.mak [1.25]: 2002/04/19 00:56:28 giles)
    	- Adds -p parameter to mkdir to suppress warning messages when the
    target already exists and to create parent directories automatically if they
    don't exist. Fixes Sourceforge bug #518742. (unix-dll.mak [1.9],
    unixinst.mak [1.26]: 2002/04/19 01:08:38 jack)
    	- Add PostScriptLevel3 as one of the Resources of the /Emulator
    category so that it shows up with "gs -h". Fixes SourceForge bug #549235.
    (int.mak [1.74]: 2002/04/26 20:51:24 ray)
    	- Removing the variable $(PSD) from lib.mak to allow graphics
    library to build independently on GS. (lib.mak [1.77]: 2002/05/05 13:44:27
    igor)
    	- The GS lib would not build. This fix corrects two minor problems.
    The routine gs_abort was added to gslib.c. The unused include file
    gmorecfg.h was removed from vdtrace.c. (lib.mak [1.78]: 2002/05/08 05:41:44
    dan)
    	- pdfwrite relied on the PostScript interpreter to load and make
    available the known encodings and glyph sets identified in src/gsccode.h.
    With this change, pdfwrite can now be used without a PostScript interpreter,
    and with fonts that do not implement the known_encode callback.
    (devs.mak [1.60], lib.mak [1.80]: 2002/05/12 22:38:08 lpd)
    	- The rule for building icc.o didn't depend on $(ECHOGS_XE), causing
    the build to possibly fail (depending on the order in which `make' built
    targets) if executed with empty output directories. (icclib.mak [1.7]:
    2002/06/05 19:55:04 lpd)
    	- update_baseline had a typo for the baseline log file.
    (toolbin/tests/update_baseline [1.6]: 2002/06/13 20:49:34 jack)
    	- Limit the number of %disk devices to 7 to prevent problems with
    the Dynalab font installer. Also return %disk devices in numeric order from
    devforall and suppress %disk devices from filenameforall to match Adobe.
    Also correct documentation of devforall (no pattern string used). Thanks to
    Nori Matsushima and Erik Strik for testing of this feature (diskn.dev).
    (int.mak [1.76]: 2002/06/14 04:04:39 ray)
    	- .pushpdf14devicefilter was defined in zdfilter.c, but depended on
    the optional pdf module's transparency features. Moves the definition of
    this routine to the conditionally included ztrans.c. Fix by L. Peter
    Deutsch, resolves SourceForge Bug 565019. (int.mak [1.77]: 2002/06/14
    09:42:54 giles)
    	- The automatically generated files src/gscedata.[ch] didn't have a
    RCS Id line. (toolbin/encs2c.ps [1.2]: 2002/06/14 13:31:53 lpd)
    	- As a result of a recent fix, an opdef table had more than 16
    entries, causing initialization to abort. (int.mak [1.78]: 2002/06/14
    14:17:56 lpd)
    	- Fixes an oversight that prevented compilation with stdpn.h
    included. (jpeg.mak [1.7]: 2002/06/16 09:11:47 lpd)
    	- Implementing pdfmark stream compression. Source forge bug "[
    558476 ] file attachment annotation uncompressed". (devs.mak [1.63]:
    2002/06/16 22:07:55 igor)
    	- Fixes minor errors in the makefile dependency lists. (The
    dependency list for gxclrast.c, in particular, had gotten badly mangled.)
    (lib.mak [1.86]: 2002/06/19 15:34:01 lpd)
    	- Fixes an omission in a dependency list. (int.mak [1.79]:
    2002/06/19 15:36:45 lpd)
    	- Fixes another omission in a dependency list. (int.mak [1.80]:
    2002/06/19 15:37:20 lpd)
    	- pdfinflt.ps should not propagate the /Prev from the input file's
    trailer since the output will only have a single xref table. Also add
    'whitespace' after a stream before 'endstream' in case the input stream did
    not have trailing whitespace (prevents /undefined errors).
    (toolbin/pdfinflt.ps [1.4]: 2002/06/19 20:13:05 ray)
    	- When building an archive of the graphics library or interpreter,
    add only the object files, not the .dev and interpreter files. Fixes
    SourceForge bug # 538311 - files missing from library archive.

    	- gxfcache.h didn't #include or define all of its prerequisites.
    (lib.mak [1.89]: 2002/06/24 05:14:15 lpd)
    	- MSVC can't handle a makefile that compiles two sets of code with
    some of the same exported names, but only linked in one set. The fix still
    requires a 1-line edit of devs.mak when using MSVC. (devs.mak [1.67]:
    2002/07/07 15:54:23 lpd)

    update version numbers after the 7.20 release. (version.mak [1.46]:
    2002/04/04 03:14:03 giles)

    Changes gs_cmap_t (internal representation of CMaps) to an abstract
    superclass with multiple implementations: standard Adobe CMapType 1,
    TrueType 16-bit cmap (Platform 3, Encoding 1, Format 4), and one-for-one.
    Adds the ability to designate a CMap as Unicode-based. Enhances pdfwrite so
    that composite fonts (including those based on TrueType Unicode fonts) with
    Unicode-based CMaps are embedded in the PDF file with the original text
    preserved and with an appropriate ToUnicode CMap, making the text searchable
    in Acrobat. (devs.mak [1.57], int.mak [1.69], lib.mak [1.70]: 2002/04/08
    21:02:44 lpd)

    Adds gscheck_pdfwrite.py and a new test class, GSFuzzyCompareTest. This test
    does fuzzy compares of ps->raster and ps->pdf->raster to help
    ensure the pdfwrite device is functioning properly.
    (toolbin/tests/gscheck_pdfwrite.py [1.1], toolbin/tests/gsconf.py [1.5],

    Updates makefile dependencies for the recent change to gdevpdfu.c.
    (devs.mak [1.59]: 2002/04/14 06:55:58 lpd)

    Adds a --[no-]pause switch to suite.tcl, for viewing suite output on the
    display. Also changes the output file names from
    t.<<date>>.<<page#>>.<<format>> to
    <<filename>>.<<page#>>.<<format>>.
    (toolbin/suite.tcl [1.6]: 2002/04/15 23:59:20 lpd)

    Deletes "Vanilla" functions, which have not been used for a long time. They
    were originally created for implementing FunctionType 4 functions using a
    callback to the PostScript interpreter, but FunctionType 4 functions have
    had their own interpreter since 3/19/2000 (first revision of gsfunc4.c).
    (lib.mak [1.74]: 2002/04/19 00:53:19 lpd)

    Add the ijs device to the default unix-gcc build. (unix-gcc.mak [1.33]:
    2002/04/19 00:54:31 giles)

    Adds a make_scaled virtual procedure to Function objects, to create a
    modified Function whose N output values are transformed linearly according
    to a supplied set of N range parameters. This is the first installment for
    implementing conversion of extended-range CIEBased color spaces to ICCBased
    spaces in pdfwrite. (lib.mak [1.75]: 2002/04/19 01:17:53 lpd)

    Puts dpsand2.dev first in the dependencies of psl2.dev, so that (eventually)
    geninit will have earlier access to the system name table for producing
    output with binary token encodings. (int.mak [1.73]: 2002/04/19 19:22:14

    Simplifies the C implementation of the known Encodings, and makes it conform
    better to Ghostscript standard coding style. (devs.mak [1.61],
    lib.mak [1.81], toolbin/encs2c.ps [1.1]: 2002/05/14 23:33:18 lpd)

    Removes an extraneous makefile dependency. (lib.mak [1.82]: 2002/05/15
    19:07:32 lpd)

    Refactors the pdfwrite driver so that none of the structures, and very few
    of the procedures, for handling text and fonts are visible to the main body
    of code, in preparation for a major rewrite of the text and font code.
    (devs.mak [1.62]: 2002/05/20 07:07:15 lpd)

    Cleans up a number of design problems in the font callback procedures: 1)
    Eliminates the gx_xfont_callbacks structure entirely. The known_encode
    procedure is no longer needed: the new facilities in gscencs.[hc] make it
    unnecessary, and none of the three implementors of the xfont interface use
    it. See below regarding glyph_name. This is a NON-BACKWARD- COMPATIBLE
    change for all clients of the glyph_name and known_encode procedures (of
    which there are, respectively, 11 and 0 in the current code base), and for
    all places that define gs_font_procs structures statically or initialize the
    callbacks dynamically (of which there are currently only two, one in
    gsfont.c and one in zbfont.c). There are also 3 identical places in the
    GhostPCL code (in plfont.c, plffont.c, and plufont.c) that will require very
    minor changes, with a small net reduction in code. 2) Deletes the
    char_xglyph2 procedure from gx_xfont_procs. It is optional, and none of the
    three current xfont implementations implements it. 3) Changes the
    char_xglyph procedure in gx_xfont_procs so that instead of a glyph_name
    callback procedure, it takes a const gs_string * argument that is the actual
    glyph name (if the glyph is not gs_no_glyph and is not a CID). This is a
    NON-BACKWARD-COMPATIBLE change for both clients and implementors of xfonts.
    (At present, there are 3 implementors, none of which use the glyph_name
    callback, and a single client call in gxccache.c.) 4) Moves the glyph_name
    procedure, which is still required for other purposes, to gs_font_procs,
    changing its declaration to int (*glyph_name)(gs_font *font, gs_glyph glyph,
    gs_const_string *pstr); This is a NON-BACKWARD-COMPATIBLE change for
    clients, but they must already change because of item (1) above. 5)
    Eliminates the registered_Encodings array in the PostScript interpreter,
    substituting the C representation of the known Encodings. (int.mak [1.75],
    lib.mak [1.84]: 2002/06/09 23:08:23 lpd)

    Moves the now-unused Pn macros to a separate file, which now can easily be
    commented out and eventually removed. (lib.mak [1.85]: 2002/06/16 08:57:57

    Adds support for incremental font copying, currently required only by the

    Adds a complete rewrite of the font and text code in pdfwrite, based on
    copying fonts incrementally to stable memory rather than trying to deal with
    fonts being freed at unpredictable times. Should fix a large number of
    current SourceForge bugs when completed: however, the code is currently in
    pre-alpha state and is not usable on any realistic input. The API is
    compatible with the previous pdfwrite text code; the choice of which set to
    use is controlled by a single, documented line in src/devs.mak.

    gs_exit() cleanup. gs_exit() is renamed gs_to_exit() since it is an about to
    terminate cleanup function, it always returns. Both gs_to_exit() and
    gs_abort are client provided functions. The client can have its own special
    cleanup on exit, and the client can decide what it wants to do in the abort
    case: exit, setjump/longjump, ... gp_do_exit() is the way for the client to
    call a system independent exit() this allows for different exit codes on
    unix and vms for instance. Only the client can call this, if so desired from
    their gs_abort(). (bench.c [1.7], gp_dvx.c [1.7], gp_iwatc.c [1.9],

## Drivers

    Fixes problems:
    	- Changes the operation of AutoFilter{Gray,Color}Images to always
    use the lossless filter (normally FlateEncode), rather than using DCTEncode
    for 8-bit-per-component images at least 64x64 in size. While this isn't
    optimal, it fixes a long-standing problem that many users have complained
    about. Fixes SourceForge #450663. (gdevpsdi.c [1.19]: 2002/04/08 21:21:21

    Implementing dynamic choice of image compression filter. Source forge bug "[

    Cleans up a number of design problems in the font callback procedures: 1)
    Eliminates the gx_xfont_callbacks structure entirely. The known_encode
    procedure is no longer needed: the new facilities in gscencs.[hc] make it
    unnecessary, and none of the three implementors of the xfont interface use
    it. See below regarding glyph_name. This is a NON-BACKWARD- COMPATIBLE
    change for all clients of the glyph_name and known_encode procedures (of
    which there are, respectively, 11 and 0 in the current code base), and for
    all places that define gs_font_procs structures statically or initialize the
    callbacks dynamically (of which there are currently only two, one in
    gsfont.c and one in zbfont.c). There are also 3 identical places in the
    GhostPCL code (in plfont.c, plffont.c, and plufont.c) that will require very
    minor changes, with a small net reduction in code. 2) Deletes the
    char_xglyph2 procedure from gx_xfont_procs. It is optional, and none of the
    three current xfont implementations implements it. 3) Changes the
    char_xglyph procedure in gx_xfont_procs so that instead of a glyph_name
    callback procedure, it takes a const gs_string * argument that is the actual
    glyph name (if the glyph is not gs_no_glyph and is not a CID). This is a
    NON-BACKWARD-COMPATIBLE change for both clients and implementors of xfonts.
    (At present, there are 3 implementors, none of which use the glyph_name
    callback, and a single client call in gxccache.c.) 4) Moves the glyph_name
    procedure, which is still required for other purposes, to gs_font_procs,
    changing its declaration to int (*glyph_name)(gs_font *font, gs_glyph glyph,
    gs_const_string *pstr); This is a NON-BACKWARD-COMPATIBLE change for
    clients, but they must already change because of item (1) above. 5)
    Eliminates the registered_Encodings array in the PostScript interpreter,
    substituting the C representation of the known Encodings.

## PDF writer

    Fixes problems:
    	- Fix : pdfwrite wrongly computed text width for fonts with unusual
    font matrix. Source Forge bug "[ 535401 ] euro glyph misplaced after
    pdfwrite". (gdevpdff.c [1.27], gdevpdfs.c [1.14]: 2002/04/11 15:59:19 igor)
    	- pdfwrite only updated the overprint flag in the graphics state for
    fill and stroke, not for images. Fixes SourceForge #525712.
    (gdevpdfg.c [1.18]: 2002/04/12 19:28:15 lpd)
    	- Adding any of the base 14 fonts to the NeverEmbed list produced
    broken output in PDF level 1.3 and above. Makes the 'default', 'screen', and
    'ebook' parameter sets not embed the base 14 fonts. (The documentation
    already said this was the case, even though it wasn't.) This is a partial
    fix for SourceForge bug #438957. (gdevpdff.c [1.28]: 2002/04/12 19:38:33
    lpd)
    	- If a shading's Function entry was an array of functions rather
    than a single function, pdfwrite wrote out an invalid Function object with a
    FunctionType of -1. (gdevpdfu.c [1.23]: 2002/04/14 06:51:45 lpd)
    	- pdfwrite would incorrectly output CalGray or CalRGB color spaces
    even if the range of the color space was not [0 1] or [0 1 0 1 0 1]
    respectively. (gdevpdfc.c [1.24]: 2002/04/14 07:09:51 lpd)
    	- Fix : pdfwrite wrongly computed line width for fonts with
    PaintType 2. (gdevpdfs.c [1.15]: 2002/04/16 10:18:59 igor)
    	- When pdfwrite wrote out a fill with an uncolored (mask) Pattern,
    all colors other than black were converted to white. (Bug found during
    unrelated pdfwrite development.) (gdevpdfb.c [1.10]: 2002/04/29 04:32:32
    lpd)
    	- pdfwrite could not convert a CIEBased color space with input
    domains larger than [0..1] to an ICCBased space, because the ICC profile
    specification inherently limits inputs to this range. The fix required
    explicitly rescaling the decoding of the color data in many different places
    when such a color space was involved: the Decode arrays in images; the
    tintTransform functions for Separation and DeviceN color spaces; the
    Background, Function, and Decode for shadings. While this was only a
    performance problem, it could be a very severe one, because it caused images
    using such extended-domain CIEBased spaces to revert to zillions of tiny
    rectangles. This change completes the ability of pdfwrite to convert
    PostScript color spaces, aside from DeviceN and Separation spaces which are
    the subject of a separate project. (gdevpdfb.c [1.11], gdevpdfc.c [1.26],

    lpd)
    	- If a Type 1 font had an initial FontMatrix other than [0.001 0 0
    0.001 0 0] and also had a Metrics entry, pdfwrite would produce incorrect
    character spacing. Fixes SourceForge #551077. (Similar to SourceForge
    #535401.) (gdevpdfs.c [1.16]: 2002/05/09 06:28:27 lpd)
    	- pdfwrite relied on the PostScript interpreter to load and make
    available the known encodings and glyph sets identified in src/gsccode.h.
    With this change, pdfwrite can now be used without a PostScript interpreter,
    and with fonts that do not implement the known_encode callback.

    	- pdfwrite produced incorrect output for ShadingType 6 and 7
    shadings if the coordinate and color data came from an array rather than a

    	- The new pdfwrite text code sometimes didn't write font changes
    correctly. The new code now has processed a substantial file correctly,
    although all non-CID-based fonts are converted to bitmaps.
    (gdevpdts.c [1.4]: 2002/06/26 00:57:30 lpd)

    Changes gs_cmap_t (internal representation of CMaps) to an abstract
    superclass with multiple implementations: standard Adobe CMapType 1,
    TrueType 16-bit cmap (Platform 3, Encoding 1, Format 4), and one-for-one.
    Adds the ability to designate a CMap as Unicode-based. Enhances pdfwrite so
    that composite fonts (including those based on TrueType Unicode fonts) with
    Unicode-based CMaps are embedded in the PDF file with the original text
    preserved and with an appropriate ToUnicode CMap, making the text searchable
    in Acrobat. (gdevpdf.c [1.44], gdevpdff.h [1.17], gdevpdfs.c [1.13],

    Restores some performance lost as a result of the fix for SourceForge
    #495414, by skipping a request for glyph widths which is redundant if the
    font doesn't have Metrics or CDevProc. Addresses SourceForge #451456 (a
    general request for better pdfwrite performance), which will be closed after
    this change. (gdevpdff.c [1.26]: 2002/04/09 23:31:44 lpd)

    Cleans up a number of design problems in the font callback procedures: 1)
    Eliminates the gx_xfont_callbacks structure entirely. The known_encode
    procedure is no longer needed: the new facilities in gscencs.[hc] make it
    unnecessary, and none of the three implementors of the xfont interface use
    it. See below regarding glyph_name. This is a NON-BACKWARD- COMPATIBLE
    change for all clients of the glyph_name and known_encode procedures (of
    which there are, respectively, 11 and 0 in the current code base), and for
    all places that define gs_font_procs structures statically or initialize the
    callbacks dynamically (of which there are currently only two, one in
    gsfont.c and one in zbfont.c). There are also 3 identical places in the
    GhostPCL code (in plfont.c, plffont.c, and plufont.c) that will require very
    minor changes, with a small net reduction in code. 2) Deletes the
    char_xglyph2 procedure from gx_xfont_procs. It is optional, and none of the
    three current xfont implementations implements it. 3) Changes the
    char_xglyph procedure in gx_xfont_procs so that instead of a glyph_name
    callback procedure, it takes a const gs_string * argument that is the actual
    glyph name (if the glyph is not gs_no_glyph and is not a CID). This is a
    NON-BACKWARD-COMPATIBLE change for both clients and implementors of xfonts.
    (At present, there are 3 implementors, none of which use the glyph_name
    callback, and a single client call in gxccache.c.) 4) Moves the glyph_name
    procedure, which is still required for other purposes, to gs_font_procs,
    changing its declaration to int (*glyph_name)(gs_font *font, gs_glyph glyph,
    gs_const_string *pstr); This is a NON-BACKWARD-COMPATIBLE change for
    clients, but they must already change because of item (1) above. 5)
    Eliminates the registered_Encodings array in the PostScript interpreter,
    substituting the C representation of the known Encodings.

    Implements the /APPEND pdfmark. (gdevpdfm.c [1.21]: 2002/06/12 23:42:30 lpd)

    Workaround for unimplemented NI, to avoid later typechecks on .PUTDICT. This
    patch adds the dictionary cos object, but does not push it in a namespace to
    be popped on occurrence of an image, as defined in section 6.2 of the
    pdfmark reference (TN 5150). Allows test file of SourceForge bug #567653 to
    run to completion. (gdevpdfm.c [1.22]: 2002/06/13 00:17:53 raph)

    2002/06/13 20:40:30 lpd)

    Implements namespaces (/NamespacePush, /NamespacePop pdfmarks) and the /NI

    copying fonts incrementally to stable memory rather than trying to deal with
    fonts being freed at unpredictable times. Should fix a large number of
    current SourceForge bugs when completed: however, the code is currently in

## PDF Interpreter

    Fixes problems:
    	- Remove "/tfopdict undef". tfopdict was defined in v.6.01 but the
    definition was since removed. Fix for bug #511232 by Alex Cherepanov.
    (lib/pdf_draw.ps [1.44]: 2002/04/10 02:23:08 ray)
    	- Handle Widths and Encoding arrays in PDF Font objects that are too
    small by using reasonable defaults. Adobe Acrobat Reader handles files with
    these problems. Fix for Artifex customer 861 for SourceForge bug#538398.
    (lib/pdf_font.ps [1.32]: 2002/04/10 15:16:00 ray)
    	- Annotations with empty AP dictionary caused a failure. Providing
    more tolerance rather such APs are invalid. Source Forge bug "[ 538428 ]
    empty appearance streams". (lib/pdf_draw.ps [1.45]: 2002/04/29 09:59:27
    igor)
    	- More tolerance to inconsistent stream length in PDF reader. Source
    Forge bug "[ 538042 ] /syntaxerror in --token--". (lib/pdf_base.ps [1.21]:
    2002/04/30 10:46:20 igor)
    	- More compatibility to Adobe interpreters in 'eexec'. This is
    NON-BACKWARD-COMPATIBLE change. Now eexec skips all whitespaces at the
    beginning of input stream, except for PFBDecode output. Thanks to L. Peter
    Deutsch for participation. Source Forge bug "[ 428891 ] Undefined commands
    interpreting Postscri". (lib/pdf_font.ps [1.33]: 2002/05/01 23:15:23 igor)
    	- Make PDF reader tolerant to singular matrix in Tj. Source Forge
    bug "[ 538055 ] /undefinedresult in --currentpoint--". (The solution was
    suggested by L. Peter Deutsch.) (lib/pdf_ops.ps [1.24]: 2002/05/08 15:51:58
    igor)
    	- Acrobat Reader apparently ignores or clamps 'setflat' parameter
    values when rendering PDF. This change emulates that behaviour by clamping
    the flatness parameter to a max of 1. Fixes SourceForge bug #555657 for
    Artifex customer #150. (lib/pdf_draw.ps [1.46]: 2002/05/22 17:29:37 ray)
    	- GS doesn't process PDF files without the required key /FontName in
    FontDescriptor dict. Adobe Acrobat Reader handles these out of spec files,
    so we also allow this. To fix this, now uses /BaseFont key when /FontName is
    missing. SF#515475. (lib/pdf_font.ps [1.34]: 2002/05/30 03:32:03 jeong)
    	- Acrobat Reader apparently processes badly formed numbers that have
    a '-' after the '.' by ignoring the fraction. If this type of tokenerror is
    detected, issue an error message and change the scanning rules to do the
    same as Adobe. SourceForge bug #558473 for Artifex customer #561.
    (lib/pdf_base.ps [1.22]: 2002/05/31 17:14:34 ray)
    	- Yet another change to allow our PDF intperpreter to tolerate an
    out of spec PDF file that Acrobat Reader (and Glance pdf tools) handle. This
    file had an 'endobj' without an 'endstream' terminating a stream. Fixes SF
    bug #570262 for Artifex customer #1060. (lib/pdf_base.ps [1.23]: 2002/06/18
    05:37:05 ray)
    	- Correct the pdfformaterror message issued when an 'endobj' is seen
    instead of 'endstream' and add a comment in the file about the error. Thanks
    to Dan Coby for the suggestions improving the previous patch.
    (lib/pdf_base.ps [1.24]: 2002/06/18 06:29:21 ray)
    	- Use actual white point in /Lab spaces, rather than relying on
    default. Fixes problem in regression file test.pdf. (lib/pdf_draw.ps [1.47]:
    2002/06/20 20:26:48 raph)
    	- Prevents /typecheck in --length-- if given a file with an Encoding
    dictionary with a Differences list has no BaseEncoding. This is perfectly
    legal -- the base encoding is the font's built-in encoding or
    StandardEncoding, per the PDF Reference (depending on whether or not the
    font is flagged as "symbolic"). Fixes SF bug #566042.
    (lib/pdf_font.ps [1.37]: 2002/06/21 06:49:50 ray)
    	- Previous fix for SF bug #566042 caused a regression by defining an
    Encoding array filled with .notdef too aggresively. Only create this array
    when we need to update it with /Differences. Some regression files were
    onechar.pdf, xngnews.pdf. The testfont.pdf file of 566042 still runs OK.
    (lib/pdf_font.ps [1.38]: 2002/06/21 07:46:37 ray)
    	- Fixes regressions caused by previous update including errors with
    ImageProb2*.pdf and aaon97_p7.pdf. Removes logic that set StandardEncoding
    if BaseEncoding wasn't set since this caused aaon97_p7 regression. Only use
    .notdefEncoding if updateencoding sees a null encoding input. This is the
    "real" fix for SF bug #566042. (lib/pdf_font.ps [1.39]: 2002/06/21 18:38:21
    ray)
    	- Wrong Widths array entry could sometimes be used when the Encoding
    (after Differences applied) mapped codes to the same glyph. Logic introduced
    in rev 1.22 only prevented some of the incorrect Width. Fixes SF bug# 570784
    for Artifex customer #150. (lib/pdf_font.ps [1.40]: 2002/06/22 05:48:47 ray)
    	- If the Differences list in the Encoding of an embedded font in a
    PDF was not in increasing order, the encoding array length needed for the
    differences could be miscalculated. Thanks to Dave Slattengren for spotting
    this. No files had been seen (yet) that tripped on this.
    (lib/pdf_font.ps [1.41]: 2002/06/25 18:58:55 ray)
    	- Generates pdfformaterror rather than PostScript error for broken
    PDF files containing unmatched >>. Workaround for SF bug #553812 for
    Artifex customer #580. (lib/pdf_base.ps [1.25]: 2002/06/26 18:35:51 ray)
    	- Generates pdfformaterror rather than PostScript error for broken
    PDF files containing unmatched >> in trailer. Workaround for SF bug
    #571851. (lib/pdf_main.ps [1.50]: 2002/06/26 18:37:16 raph)
    	- Add the option -dUseCropBox to set the page size from the CropBox
    rather than the MediaBox. This is appropriate when using ghostscript to view
    PDF files or convert to bitmaps. It probably isn't appropriate for printing.
    Fixes SourceForge bugs #522486, "Wromg size EPS generated from PDF" and
    #538267 "Problems with Media Box in PDF and PS interpreter".
    (lib/pdf_main.ps [1.51]: 2002/06/28 10:55:43 ghostgum)
    	- When drawing PDF annotation links which are missing a /Border,
    assume the default /Border [0 0 1]. Previously ghostscript assumed that
    links without a /Border should not be drawn, which is contrary to the PDF
    specification. (lib/pdf_draw.ps [1.48]: 2002/06/28 23:10:10 ghostgum)
    	- If a PDF annotation specified other than the default color with
    /C, pass this into the pdfmark logic as /Color. (lib/pdf_main.ps [1.52]:
    2002/06/28 23:10:45 ghostgum)
    	- (PDF interpreter) wrong stack balance in 'resolvedest'. Source
    Forge bug "[ 571912 ] pdfwrite: /rangecheck in --pdfmark--"
    (lib/pdf_main.ps [1.53]: 2002/07/01 10:49:38 igor)

## Interpreter

    Fixes problems:
    	- Skip the (potentially time consuming) work of setting the color
    space if it is the same as the currentcolorspace. Fixes SF #539327 for
    Artifex customer #830. (lib/gs_lev2.ps [1.15]: 2002/04/06 01:18:56 ray)
    	- Check the return code from gs_upathbbox() and zero the bbox if
    there is no current point. Propagate other errors up. Adobe implementations
    throw nocurrentpoint error, but this is not valid per the PLRM. Fix for
    #520972 by Alex Cherepanov. (zupath.c [1.5]: 2002/04/09 22:54:00 ray)
    	- Delete code that caused unshifted arrow keys to enter garbage
    chars into the command line buffer. Now arrow keys scroll the image window
    regardless of the shift state. Fix by Alex Cherepanov. (dwtext.c [1.8]:
    2002/04/09 23:26:29 ray)
    	- Fix for #540871. Clean up compiler warnings in zfsample.c. Note:
    The addition of two include files in zfsample.c forces a change in
    dependencies in int.mak. (zfsample.c [1.6]: 2002/04/11 02:18:14 dan)
    	- Adding any of the base 14 fonts to the NeverEmbed list produced
    broken output in PDF level 1.3 and above. Makes the 'default', 'screen', and
    'ebook' parameter sets not embed the base 14 fonts. (The documentation
    already said this was the case, even though it wasn't.) This is a partial
    fix for SourceForge bug #438957. (lib/gs_pdfwr.ps [1.16]: 2002/04/12
    19:38:33 lpd)
    	- The Matrix entry of ShadingType 1 shading dictionaries was
    required; it is now (correctly) optional. (zshade.c [1.9]: 2002/04/14
    02:48:26 lpd)
    	- ShadingType 1 shadings whose Function was an array required the
    individual functions to take 1 argument, rather than the correct 2; shadings
    whose Function was not an array didn't check that the function took the
    correct number of arguments. (The Genoa FTS does not check either of these.)
    (zshade.c [1.10]: 2002/04/14 03:10:01 lpd)
    	- Fix : Replacing the even-odd filing rule with the non-zero filling
    rule for fonts. Source Forge bug "[ 539359 ] problem rendering euro
    character". (zchar1.c [1.14]: 2002/04/16 11:03:29 igor)
    	- Bump the DEFAULT_VM_THRESHOLD value up to prevent excessive GC.
    This is a tuned parameter that may need to be adjusted in the future if
    -dNOGC runs significantly faster than the normal case. The previous values
    were established a long time ago when memory was a more expensive resource.
    Fixes SourceForge bug #421057. (zvmem2.c [1.6]: 2002/04/16 21:41:28 ray)
    	- Fix : Type2 interpreter state was wrongly backed up for sbw
    fallback. Source Forge bug "[ 541877 ] /invalidfont on Kozuka Mincho".
    (zchar1.c [1.15]: 2002/04/18 14:26:27 igor)
    	- ShadingType 4-7 shadings with a Function and with data coming from
    a stream rather than an array incorrectly expected N value ranges in their
    Decode array, where N is the number of components in the color space, rather
    than a single range for the function argument. Finishes fixing SourceForge
    #546415. (zshade.c [1.11]: 2002/04/20 05:51:52 lpd)
    	- Taking off a debbugging code. (zchar1.c [1.16]: 2002/04/21
    17:45:41 igor)
    	- Previous change to optimize setcolorspace (for SF bug #539327)
    caused a regression since the CIE space cache management was confused when
    CIEBased (including ICCBased) colorspace was the base space for some other
    space such as Pattern, Indexed, DeviceN, Separation. The discussion of the
    fix of the cache handling will be in doc/Projects.htm. The .dosetcolorspace
    is now used internally when setting up the base space for the "outer"
    colorspaces. Fixes regression caused by rev 1.15 of gs_lev2.ps and partial
    fix for SF bug #547695. Analysis of problem by L. Peter Deutsch (lpd).

    	- ReusableStreams couldn't handle %diskn devices (or even %os% files
    for that matter). Add filename parsing for iodev to make_rfs. Problem showed
    as invalidaccess when opening CIDFonts that resided on %disk devices. Fix
    for Artifex customer #411. (zfrsd.c [1.8]: 2002/04/29 22:33:50 ray)
    	- More compatibility to Adobe interpreters in 'eexec'. This is
    NON-BACKWARD-COMPATIBLE change. Now eexec skips all whitespaces at the
    beginning of input stream, except for PFBDecode output. Thanks to L. Peter
    Deutsch for participation. Source Forge bug "[ 428891 ] Undefined commands

    	- When CIEBasedDEF or DEFG color space is set, DecodeABC was not set
    properly and remained as abc_identity. This caused wrong color generation in
    CIEBasedDEFG space. Analysis and fix by L. Peter Deutsch (lpd). Fixes
    SF#542786. (zcie.c [1.9]: 2002/05/02 17:47:02 jeong)
    	- Allow readonly FontMatrix in font type 9. Thanks for Ray Johnston
    for participation. Source Forge bug "[ 551958 ] Problems with CIDFont:
    RcPNOWkana-GB". (lib/gs_cidfn.ps [1.24]: 2002/05/06 11:49:30 igor)
    	- A rounding problem made installation of CIEBased color spaces
    non-idempotent, which could cause seriously incorrect rendering of CIEBased
    colors in the sequence [/CIEBased...] setcolorspace, gsave, [/Pattern
    [/CIEBased...]] setcolorspace, grestore. Fixes SourceForge bug #547695, q.v.

    	- Acrobat Reader apparently processes badly formed numbers that have
    a '-' after the '.' by ignoring the fraction. If this type of tokenerror is

    future by pdfwrite.) (zcharout.c [1.9]: 2002/06/08 01:22:26 lpd)
    	- Limit the number of %disk devices to 7 to prevent problems with
    the Dynalab font installer. Also return %disk devices in numeric order from
    devforall and suppress %disk devices from filenameforall to match Adobe.
    Also correct documentation of devforall (no pattern string used). Thanks to

    14:17:56 lpd)
    	- Because of a bug introduced by the removal of known_encode,
    accented Type 1/2 font characters defined using the 'seac' operator could
    cause an error in pdfwrite. Fixes the recent pdfwrite regression ERROR in
    Svd.pdf. (zchar1.c [1.18]: 2002/06/15 04:19:44 lpd)
    	- Correct the display device color mapping functions that were
    wrong. Change 4-bit mapping functions to standard VGA. Correct 16-bit native
    RGB and 32-bit xRGB mapping functions. Add RGB to color mapping functions
    for CMYK formats, needed by anti-aliasing. (dpmain.c [1.8], dwimg.c [1.7]:

    (zimage.c [1.9]: 2002/06/22 11:16:12 igor)
    	- Make sure that the .pdfmapchars which generates the CharStrings
    dictionary includes all of the glyphs mentioned by name in the encoding
    array (after the Encoding::Differences are applied). This fixes the ".notdef
    substituted for ccaron" problem that occurs after pdf_font.ps rev 1.40 fix
    prevents the "typecheck in length" mentioned in SF bug #567580 for Artifex
    customer #1110. (lib/gs_ttf.ps [1.15]: 2002/06/25 06:40:10 ray)
    	- Fixes two uninitialized memory reads, by zeroing the gs_allocated
    field of newly allocated allocators, and the userdict_index field of dict
    stacks in newly allocated contexts. (icontext.c [1.11]: 2002/06/26 20:01:53

    	- Fixes uninitialized memory read of stack-allocated stream in

    of filenameforall has the same operand stack. (lib/gs_diskn.ps [1.3]:

    	- Define /buildtime in systemdict because Adobe does so and some
    protected fonts use it as ID. Fix provided by Alex Cherepanov. SourceForge
    bug #458500. (lib/gs_lev2.ps [1.19]: 2002/06/27 16:35:31 ray)
    	- The return status values from 'sgets' were not handled properly.
    Now the functions that use 'sgets', check the return status and convert them
    into proper gs_errors. SF#569111 (iscanbin.c [1.11]: 2002/07/01 14:27:43
    jeong)
    	- If the 'resourceforall' operator's procedure operand gets an error
    or performs a 'stop', Adobe interpreters return an operand stack with the
    four operands to resourceforall removed from the stack. The comments
    suggested this was the intent, but the logic did not work this way and
    instead left all four operands on the stack. Fixes CSL startup problem for
    Artifex customer #150. (lib/gs_res.ps [1.23]: 2002/07/02 18:28:31 ray)

    TrueType 16-bit cmap (Platform 3, Encoding 1, Format 4), and one-for-one.
    Adds the ability to designate a CMap as Unicode-based. Enhances pdfwrite so
    that composite fonts (including those based on TrueType Unicode fonts) with
    Unicode-based CMaps are embedded in the PDF file with the original text
    preserved and with an appropriate ToUnicode CMap, making the text searchable

    cleanup on exit, and the client can decide what it wants to do in the abort
    case: exit, setjump/longjump, ... gp_do_exit() is the way for the client to

    Cleans up a number of design problems in the font callback procedures: 1)
    Eliminates the gx_xfont_callbacks structure entirely. The known_encode
    procedure is no longer needed: the new facilities in gscencs.[hc] make it
    unnecessary, and none of the three implementors of the xfont interface use
    it. See below regarding glyph_name. This is a NON-BACKWARD- COMPATIBLE
    change for all clients of the glyph_name and known_encode procedures (of
    which there are, respectively, 11 and 0 in the current code base), and for
    all places that define gs_font_procs structures statically or initialize the
    callbacks dynamically (of which there are currently only two, one in
    gsfont.c and one in zbfont.c). There are also 3 identical places in the
    GhostPCL code (in plfont.c, plffont.c, and plufont.c) that will require very
    minor changes, with a small net reduction in code. 2) Deletes the
    char_xglyph2 procedure from gx_xfont_procs. It is optional, and none of the
    three current xfont implementations implements it. 3) Changes the
    char_xglyph procedure in gx_xfont_procs so that instead of a glyph_name
    callback procedure, it takes a const gs_string * argument that is the actual
    glyph name (if the glyph is not gs_no_glyph and is not a CID). This is a
    NON-BACKWARD-COMPATIBLE change for both clients and implementors of xfonts.
    (At present, there are 3 implementors, none of which use the glyph_name
    callback, and a single client call in gxccache.c.) 4) Moves the glyph_name
    procedure, which is still required for other purposes, to gs_font_procs,
    changing its declaration to int (*glyph_name)(gs_font *font, gs_glyph glyph,
    gs_const_string *pstr); This is a NON-BACKWARD-COMPATIBLE change for
    clients, but they must already change because of item (1) above. 5)

    (lib/gs_cff.ps [1.13]: 2002/07/06 02:49:39 lpd)

## Streams

    Fixes problems:
    	- More compatibility to Adobe interpreters in 'eexec'. This is
    NON-BACKWARD-COMPATIBLE change. Now eexec skips all whitespaces at the
    beginning of input stream, except for PFBDecode output. Thanks to L. Peter
    Deutsch for participation. Source Forge bug "[ 428891 ] Undefined commands
    interpreting Postscri". (seexec.c [1.7]: 2002/05/01 23:15:23 igor)
    	- Correct the VMS exit codes for exit_OK and exit_FAILED which
    depend on the compiler (Forrest Cahoon). Return the correct exit code from
    main for VMS. (stdpre.h [1.8]: 2002/05/15 12:11:44 ghostgum)
    	- Fixes an oversight that prevented compilation with stdpn.h
    included. (stdpre.h [1.10]: 2002/06/16 09:11:47 lpd)

    Documents the fact that exceptional stream conditions remain set until a
    client clears them. (scommon.h [1.7]: 2002/06/16 03:20:39 lpd)

    Removes all uses of the now-deprecated Pn macros from the stream
    implementation code. (sa85d.c [1.6], scfd.c [1.6], scfdtab.c [1.4],
    scfe.c [1.5], scfetab.c [1.5], sfxfd.c [1.9], sfxstdio.c [1.7],
    siinterp.c [1.5], siscale.c [1.7], stream.c [1.19]: 2002/06/16 03:58:14 lpd)

    Removes all uses of the now-deprecated Pn macros from the stream header
    files. (sbcp.h [1.5], scommon.h [1.8], sdcparam.h [1.5], sdct.h [1.7],

    szlibxx.h [1.5]: 2002/06/16 05:00:54 lpd)

    Removes all uses of the now-deprecated Pn macros from system header
    wrappers. (stdio_.h [1.7]: 2002/06/16 05:03:12 lpd)

    Moves the now-unused Pn macros to a separate file, which now can easily be
    commented out and eventually removed. (stdpn.h [1.1], stdpre.h [1.9]:
    2002/06/16 08:57:57 lpd)

    Adds a missing close-comment (*/) marker. (stdpn.h [1.2]: 2002/06/16
    08:59:16 lpd)

## Library

    Fixes problems:
    	- Compiling with -dPROFILE could cause compiler warnings about
    "memxxx redefined" (memset, memcpy, etc.). (memory_.h [1.5]: 2002/04/08
    20:42:01 lpd)
    	- Indexed color spaces weren't implemented for ShadingType 4-7
    shadings. (gxshade.c [1.9], gxshade.h [1.7], gxshade4.c [1.9]: 2002/04/14
    04:30:47 lpd)
    	- If a shading's Function entry was an array of functions rather
    than a single function, pdfwrite wrote out an invalid Function object with a
    FunctionType of -1. (gsfunc3.c [1.7]: 2002/04/14 06:51:45 lpd)
    	- Radial shading fills with /Extend are now clipped correctly. Also
    Radial shadings with 2 radii for which the difference is small or zero, now
    does as Adobe does. Fixes SourceForge bug #219798, #542457
    (gxshade1.c [1.13]: 2002/04/18 08:12:56 jeong)
    	- Fix : Type2 interpreter state was wrongly backed up for sbw
    fallback. Source Forge bug "[ 541877 ] /invalidfont on Kozuka Mincho".
    (gstype2.c [1.18], gxtype1.c [1.13]: 2002/04/18 14:26:27 igor)
    	- ShadingType 4-7 shadings with a Function incorrectly read N values
    from their data stream, where N is the number of components in the color
    space, rather than a single entry for the function argument. Fixes
    SourceForge #546415. (gxshade.c [1.10]: 2002/04/20 05:27:11 lpd)
    	- The make_scaled procedure for PostScript Calculator Functions
    didn't copy the data_source, causing a memory access error when converting
    the Function to printable form. (gsfunc4.c [1.11]: 2002/04/20 07:05:39 lpd)
    	- Arrayed Output Functions (used internally to represent an array of
    Functions) didn't compute or store their Domain, causing pdfwrite to write
    them incorrectly. (Bug found during development of pdfwrite.)
    (gsfunc3.c [1.9]: 2002/04/20 18:50:36 lpd)
    	- ShadingType 4-7 shadings didn't check the validity of ColorSpace
    and BBox like other shadings, and when used with a Function, didn't check
    that the Function had the correct number of inputs and outputs. (Bug found
    during pdfwrite development.) (gsshade.c [1.7]: 2002/04/21 02:48:36 lpd)
    	- Arrayed Output functions didn't check whether their input and
    output buffers overlapped in memory. This produced incorrect output from
    ShadingType 4-7 shadings with a /Function entry that was an array of N
    1-output Functions rather than a single N-output function. (Bug discovered
    during pdfwrite development.) (gsfunc3.c [1.10]: 2002/04/23 01:10:38 lpd)
    	- Radial shading worked only if the original coordinate unit is
    identical to the coordinate unit of the output device. Now it works for
    every case. Fixes SF#542457. (gxshade1.c [1.14]: 2002/04/23 06:13:58 jeong)
    	- Fixes an incorrect comment; eliminates a redundant initialization.
    (gsfunc3.c [1.11]: 2002/04/23 16:46:30 lpd)
    	- FunctionType 4 functions with more than 1 output didn't scale the
    output properly. (gsfunc4.c [1.12]: 2002/04/23 18:38:52 lpd)
    	- gx_device_clip::memory was not set but used while intersecting
    clip paths. Source Forge bug "[ 547111 ] segfault with pdf using ppmraw".
    (gxclip.c [1.7]: 2002/04/26 08:52:54 igor)
    	- A rounding problem made installation of CIEBased color spaces
    non-idempotent, which could cause seriously incorrect rendering of CIEBased
    colors in the sequence [/CIEBased...] setcolorspace, gsave, [/Pattern
    [/CIEBased...]] setcolorspace, grestore. Fixes SourceForge bug #547695, q.v.
    (gscie.c [1.9], gscie.h [1.9]: 2002/05/07 19:51:53 lpd)
    	- The GS lib would not build. This fix corrects two minor problems.
    The routine gs_abort was added to gslib.c. The unused include file
    gmorecfg.h was removed from vdtrace.c. (gslib.c [1.8], vdtrace.c [1.4]:
    2002/05/08 05:39:12 dan)
    	- A minor cleanup of vdtrace.c . (vdtrace.c [1.5]: 2002/05/08
    06:57:35 igor)
    	- pdfwrite relied on the PostScript interpreter to load and make
    available the known encodings and glyph sets identified in src/gsccode.h.
    With this change, pdfwrite can now be used without a PostScript interpreter,
    and with fonts that do not implement the known_encode callback.
    (gdevpsf2.c [1.19], gdevpsft.c [1.13], gscedata.c [1.1], gscencs.c [1.1],
    gscencs.h [1.1]: 2002/05/12 22:38:08 lpd)
    	- as a result of a recent fix, the CIEBased color cache code for
    ensuring that black (0,0,0) mapped precisely no longer worked.
    (gscie.c [1.10]: 2002/05/15 23:49:39 lpd)
    	- gdevpsf.h didn't define the 'stream' type, which it references.
    (gdevpsf.h [1.14]: 2002/05/17 16:38:12 lpd)
    	- The previous fix for numerical inaccuracies in CIE cache sampling
    could lead to extremely long computation times. (gscie.c [1.11],
    gscie.h [1.11]: 2002/05/19 15:50:00 lpd)
    	- completing "remove dependency of pdfwrite on PS" (gscencs.c [1.3]:
    2002/05/20 06:33:36 igor)
    	- In the output of the PDF 1.4 image buffer to the target device,
    sets color space in graphics state explicitly to RGB (to match the color
    space in the image), and also sets the device in the graphics state to the
    target device. It may be that a better fix would be to make the image work
    even without these explicit state settings, but this seems to work for now.
    Fixes SF #520686. (gdevp14.c [1.10]: 2002/05/22 05:07:48 raph)
    	- In radial shading, if radius of a circle is 0, there was division
    by zero. This is a regression for the fix of SF#219798. Now fixed.
    (gxshade1.c [1.15]: 2002/05/26 05:03:31 jeong)
    	- Increase clist cmd reading buffer size to 4K to be able to handle
    larger halftone bitmaps. The old size of 800 could cause the clist high
    level path logic to revert to 'default' filling which created VERY large
    clist temp files. SourceForge bug 542664 for Artifex customer 710.
    (gxcldev.h [1.7]: 2002/05/29 08:09:59 ray)
    	- Add type cast to prevent problem on OpenVMS (gdevp14.c [1.11]:
    2002/05/31 13:05:58 joukj)
    	- Fixes off-by-one error in loop termination for CIE cache
    initializations. (gscie.c [1.12]: 2002/06/06 06:55:12 raph)
    	- Fixes uninitialized base buffer and failure to properly increment
    a p14_device refcount in the pdf14 imaging code. (gdevp14.c [1.12]:
    2002/06/06 06:57:12 raph)
    	- Fixes a bug in writing "stripped" TrueType fonts. (Only affects
    font copying.) (gdevpsft.c [1.16]: 2002/06/12 22:06:51 lpd)
    	- Limit the number of %disk devices to 7 to prevent problems with
    the Dynalab font installer. Also return %disk devices in numeric order from
    devforall and suppress %disk devices from filenameforall to match Adobe.
    Also correct documentation of devforall (no pattern string used). Thanks to
    Nori Matsushima and Erik Strik for testing of this feature (diskn.dev).
    (gsiodisk.c [1.2]: 2002/06/14 04:04:39 ray)
    	- The automatically generated files src/gscedata.[ch] didn't have a
    RCS Id line. (gscedata.c [1.3], gscedata.h [1.2]: 2002/06/14 13:31:53 lpd)
    	- psf_write_truetype_font and psf_write_cid2_font copied hmtx and
    vmtx rather than getting the actual metrics through the font virtual
    procedures, which produced incorrect output if the font was defined
    incrementally and used MetricsCount. (This only affected pdfwrite.)
    (gdevpsf.h [1.18], gdevpsft.c [1.18]: 2002/06/18 00:31:20 lpd)
    	- Removes incorrect #includes of errors.h, which is a PostScript
    interpreter file, from library files. (gsfcmap1.c [1.3], gxchar.c [1.16]:
    2002/06/19 15:33:01 lpd)
    	- When drawing with anti-aliasing on devices with less than
    8-bit/pixel, extract the correct existing pixel value. (gdevdbit.c [1.5]:
    2002/06/21 22:05:33 ghostgum)
    	- Propagate possible errors from pdf_end_image_binary.
    (gsimage.c [1.7], gsimage.h [1.6], gsptype1.c [1.7], gxccache.c [1.10]:
    2002/06/22 11:16:12 igor)
    	- gxfcache.h didn't #include or define all of its prerequisites.
    (gxfcache.h [1.7]: 2002/06/24 05:14:15 lpd)
    	- Fixes an off-by-1 bug in the code for accessing Subrs in copied
    fonts. (gxfcopy.c [1.4]: 2002/06/24 17:28:11 lpd)
    	- copying a CIDFontType 2 font didn't copy numGlyphs, causing glyphs
    to disappear. (gxfcopy.c [1.6]: 2002/06/24 23:48:31 lpd)
    	- Fixes an off-by-1 error in copying [Global]Subrs.
    (gxfcopy.c [1.7]: 2002/06/25 04:32:48 lpd)
    	- gs_copy_font for CIDFontType 0 fonts didn't copy GlobalSubrs
    correctly. (gxfcopy.c [1.8]: 2002/06/25 05:22:56 lpd)
    	- Two places associated with font writing didn't add in
    subroutineNumberBias when interpreting a Type 1 / Type 2 CharString.
    (gdevpsfx.c [1.15], gxtype1.c [1.14]: 2002/06/25 05:25:45 lpd)
    	- The GSubrs for CIDFontType 0 fonts were not written, possibly
    producing invalid embedded fonts from pdfwrite. Fixes SourceForge #571911.
    (gdevpsf.h [1.19], gdevpsf2.c [1.21]: 2002/06/25 06:52:05 lpd)
    	- Fixes two uninitialized memory reads, by zeroing the gs_allocated
    field of newly allocated allocators, and the userdict_index field of dict
    stacks in newly allocated contexts. (gsalloc.c [1.17]: 2002/06/26 20:01:53
    raph)
    	- Fix uninitialized memory read of pcache->order.data_memory by
    zeroing it on construction. (gxht.c [1.7]: 2002/06/26 20:03:21 raph)
    	- Code for writing and copying Type 1 fonts didn't correctly handle
    Subrs arrays with null elements. (gdevpsf1.c [1.15], gdevpsf2.c [1.22],
    gxfcopy.c [1.9]: 2002/06/26 23:17:24 lpd)
    	- Allocating the glyphs and names arrays for copied fonts used the
    wrong structure descriptor. (gxfcopy.c [1.10]: 2002/06/27 03:55:39 lpd)
    	- Fixes 3 minor problems with font copying: GC overhead was
    substantial; the components of composite glyphs were not copied; the
    encoding index was not copied when copying a complete font.
    (gxfcopy.c [1.12]: 2002/06/28 01:47:22 lpd)
    	- The size of the version field of the ttf_maxp_t structure was
    defined incorrectly as 2 rather than 4. (This structure wasn't referenced
    anywhere.) (gxttf.h [1.6]: 2002/06/28 05:27:22 lpd)
    	- Font copying did not allocate its tables correctly when copying
    incrementally downloaded TrueType fonts, and did not implement encode_char
    correctly for TrueType fonts when glyph_space == GLYPH_SPACE_NAME. (Only
    affects new pdfwrite text code.) (gxfcopy.c [1.13]: 2002/06/28 22:35:26 lpd)
    	- The return status values from 'sgets' were not handled properly.
    Now the functions that use 'sgets', check the return status and convert them
    into proper gs_errors. SF#569111 (gsmatrix.c [1.6], gsparam2.c [1.6],
    gxclrast.c [1.16]: 2002/07/01 14:27:43 jeong)
    	- The hmtx/vmtx tables generated from the glyph metric data for
    embedded TrueType fonts in PDF output were incorrect, due to a misreading of
    the TrueType spec. (This only affects the new pdfwrite text code: the old
    code does not generate the tables this way.) (gdevpsft.c [1.20]: 2002/07/06

    Changes gs_cmap_t (internal representation of CMaps) to an abstract
    superclass with multiple implementations: standard Adobe CMapType 1,
    TrueType 16-bit cmap (Platform 3, Encoding 1, Format 4), and one-for-one.
    Adds the ability to designate a CMap as Unicode-based. Enhances pdfwrite so
    that composite fonts (including those based on TrueType Unicode fonts) with
    Unicode-based CMaps are embedded in the PDF file with the original text
    preserved and with an appropriate ToUnicode CMap, making the text searchable
    in Acrobat. (gdevpsfm.c [1.10], gsfcid2.c [1.1], gsfcmap.c [1.18],

    Restores some performance lost as a result of the fix for SourceForge
    #495414, by skipping a request for glyph widths which is redundant if the

    gs_exit() cleanup. gs_exit() is renamed gs_to_exit() since it is an about to
    terminate cleanup function, it always returns. Both gs_to_exit() and
    gs_abort are client provided functions. The client can have its own special
    cleanup on exit, and the client can decide what it wants to do in the abort
    case: exit, setjump/longjump, ... gp_do_exit() is the way for the client to
    call a system independent exit() this allows for different exit codes on
    unix and vms for instance. Only the client can call this, if so desired from
    their gs_abort(). (gsexit.h [1.7], gslib.c [1.9]: 2002/05/14 14:59:41

    Cleans up a number of design problems in the font callback procedures: 1)
    Eliminates the gx_xfont_callbacks structure entirely. The known_encode
    procedure is no longer needed: the new facilities in gscencs.[hc] make it
    unnecessary, and none of the three implementors of the xfont interface use
    it. See below regarding glyph_name. This is a NON-BACKWARD- COMPATIBLE
    change for all clients of the glyph_name and known_encode procedures (of
    which there are, respectively, 11 and 0 in the current code base), and for
    all places that define gs_font_procs structures statically or initialize the
    callbacks dynamically (of which there are currently only two, one in
    gsfont.c and one in zbfont.c). There are also 3 identical places in the
    GhostPCL code (in plfont.c, plffont.c, and plufont.c) that will require very
    minor changes, with a small net reduction in code. 2) Deletes the
    char_xglyph2 procedure from gx_xfont_procs. It is optional, and none of the
    three current xfont implementations implements it. 3) Changes the
    char_xglyph procedure in gx_xfont_procs so that instead of a glyph_name
    callback procedure, it takes a const gs_string * argument that is the actual
    glyph name (if the glyph is not gs_no_glyph and is not a CID). This is a
    NON-BACKWARD-COMPATIBLE change for both clients and implementors of xfonts.
    (At present, there are 3 implementors, none of which use the glyph_name
    callback, and a single client call in gxccache.c.) 4) Moves the glyph_name
    procedure, which is still required for other purposes, to gs_font_procs,
    changing its declaration to int (*glyph_name)(gs_font *font, gs_glyph glyph,
    gs_const_string *pstr); This is a NON-BACKWARD-COMPATIBLE change for
    clients, but they must already change because of item (1) above. 5)
    Eliminates the registered_Encodings array in the PostScript interpreter,
    substituting the C representation of the known Encodings.

# Version 7.20 (2002-04-03)

This is the first development release after the 7.0x series. While it is a development release, it is likely to be quite stable and robust, largely thanks to automated regression testing.

Major changes include:

- Support for external font renderers such as Agfa UFST.
- An optional "diskn" feature that emulates the "%disk" devices found on some Adobe printers.
- The `-dSAFER` flag now tightens read access to arbitrary files, as well as write access. Thus, `-dSAFER` in this release is equivalent to `-dSAFER -dPARANOIDSAFER` in 7.04. This will break some viewers, notably gv.

In addition, the following improvements have been merged from the 7.04 release:

- A rather serious security hole, where PostScript code could cause arbitrary commands to be executed, has been patched.
- This release integrates the IJS driver, which makes it much easier to add and upgrade printer drivers without needing to recompile Ghostscript.
- There is a configure script for automatically configuring the build system on Unix platforms. Those who enjoy the fun of hand-editing the makefile are still welcome to do so.

And, of course, the usual bug fixing and performance enhancement.

There has also been considerable development of our DeviceN implementation and related color work on a private branch. These new features are not included in this release. We expect to merge them into the main branch soon.

There exists another private branch which integrates PCL and PostScript/PDF in the same executable. Again, that work is not reflected in this release.

The following SourceForge bug numbers were open at the time of release: 219798, 405342, 406979, 407342, 414947 414985, 415142, 416131, 416830, 418241, 421057, 423838, 427193, 427314, 427347, 428891, 428973, 432040, 434277, 436099, 437285, 438957, 443745, 446344, 446672, 448199, 450663, 451456, 452155, 453969, 458261, 458500, 458775, 458780, 459647, 462221, 465720, 465936, 468762, 472681, 474745, 475147, 477644, 479071, 482033, 482038, 483629, 484752, 484753, 485498, 485510, 485510, 487953, 493348, 495319, 498595, 503794, 505047, 505151, 505429, 506375, 508081, 508675, 509646, 510808, 511232, 513905, 514616, 514898, 515475, 515966, 516653, 517349, 518742, 520686, 520972, 521354, 521597, 521664, 521916, 522486, 522507, 524292, 525508, 525712, 526099, 526491, 527152, 527525, 528647, 529103, 529411, 529578, 530011, 530213, 530588, 531300, 532468, 533467, 534637, 535366, 535395, 535395, 535401, 535752, 535836, 535997, 536863, 536877, 537066, 538033, 538042, 538055, 538267, 538311, 538398, 538428.

### Incompatible changes

    (Interpreter)
    	- Updates clients and implementors for the new glyph outline data
    structure.
    	- -dSAFER flag now restricts read access to arbitrary files in
    addition to restricting write access.
    	- While not strictly an incompatible change, authors of drivers
    with potential security implications are encouraged to review the
    security changes, including the LockSafetyParams mechanism.

    (Library)
    	- Changes all procedures for getting glyph outline data to return
    the data by storing it into a gs_glyph_data_t structure that includes memory
    management information.  This is a NON-BACKWARD-COMPATIBLE change to both
    implementors and clients.  It corrects a significant design error: formerly
    these procedures encoded memory management information in their return code,
    which was obscure and error-prone.  See src/gsgdata.[hc].

## Documentation

    Fixes problems:
    	- Fixes minor problems with the English introduced by the most
    recent change. (doc/Use.htm [1.37]: 2001/12/08 15:41:28 lpd)
    	- A "\" should have been a "\e" for troff. (fix from Nelson Beebe)
    (man/ansi2knr.1 [1.3]: 2001/12/31 22:43:35 lpd)
    	- some files were missing the RCS 'Id' line with the last
    modification date. partial fix for Sourceforge bug #500922.
    (doc/index.html [1.3]: 2002/01/09 21:04:20 giles)

    (doc/C-style.htm [1.23]: 2002/01/16 16:05:54 lpd)
    	- Improve security in a (mostly) backward compatible fashion adding
    more flexible file access paths (PermitFile...) as user paramters and adding
    the facility to return to NOSAFER mode after running jobs (files/procedures)
    in SAFER mode. This should address SF bug #474582 and eliminate the need for
    the RedHat PARANOIDSAFER patch. (doc/Language.htm [1.38],
    doc/Use.htm [1.40]: 2002/01/24 06:33:33 rayjj)

    $Id: lines from having the keyword replacement. This was broken for a LONG
    time. (doc/gsdoc.el [1.4]: 2002/02/22 19:08:29 ray)
    	- POSIX 2001 has obsoleted tail +128c. Document the new convention
    'tail -c +129' as an alternate. (doc/Use.htm [1.46]: 2002/03/28 21:28:06

    branch-sensitivity options. (doc/Release.htm [1.53]: 2002/03/29 07:42:04
    giles)
    	- the cvs2hist invocation must use -b in the rlog tags, rather than
    -r to correctly identify the head branch. Some files are tagged as 'MAIN'
    rather than 'HEAD'. (doc/Release.htm [1.57]: 2002/04/03 06:44:57 giles)
    	- further clarify the call to cvs2hist for the main branch.

    Removes the admonishment to update PVERSION and JVERSION from the Makefile
    documentation. The build dependencies were removed earlier to reduce user
    confusion; they're currently vestigial in expectation of future build
    incompatibilities. This is the second half of the fix for sf bug #457838.
    (doc/Make.htm [1.37]: 2001/10/24 22:22:35 giles)

    Improve security for device related access to the file system and to pipes
    by allowing the dangerous parameters to be locked (for example, OutputFile).
    The locking is performed after command line parameters are established.
    Locking is not turned on by default as a result of this change, but
    -d.LockSafetyParams=true can be added to the command line to accomplish
    this. Related to SF bug #474582 (sort of). (doc/Language.htm [1.35]:
    2001/12/22 00:44:01 rayjj)

    Documents the work-around of using '#' instead of '=' to separate command
    line options from their arguments. The was previously listed only as a quirk
    of the Wacom build on MS-DOS, but is also needed on win32 because the
    command shell treats '=' as whitespace in passing arguments to batch files
    (like ps2pdf.bat). Closes SourceForge bug #483066. Also documents that
    MS-DOS is no longer a supported operating system. (doc/Use.htm [1.41]:

## Procedures

    Fixes problems:
    	- tmake recognized the end of a rule body by a blank line, rather
    than by a line that didn't begin with a tab. Fixes SourceForge #415170.
    (toolbin/tmake.tcl [1.4]: 2001/10/24 05:45:55 lpd)
    	- the icclib makefile comments were out of date; the build rule
    referred to gs_stdio_h, which no longer exists; the build rule for gsicc.o
    referred to icc_h, which was not defined at that point. (gs.mak [1.7],
    icclib.mak [1.4], lib.mak [1.57]: 2001/10/25 21:17:16 lpd)
    	- the recent (previous) update to tmake.tcl omitted a line, which
    caused the detection of out-of-date files to stop working.
    (toolbin/tmake.tcl [1.6]: 2001/10/25 22:02:11 lpd)
    	- lib.mak failed to include the dependency of gxdevcli.h on
    gstparam.h. (lib.mak [1.58]: 2001/10/31 07:10:59 lpd)
    	- makes png the default device on macos which is better supported
    than the pbm. (macosx.mak [1.2]: 2001/11/25 06:42:59 giles)
    	- Repairs code problems with the fix for bug #224056: non-re-entrant
    code, bad formatting, unused variables and computations, and a missing
    #include. (int.mak [1.53]: 2001/12/07 05:41:59 lpd)
    	- For images specified in general CIEBased color spaces, pdfwrite
    would divide the image into tiny rectangles. If the output level is PDF 1.3
    or higher, pdfwrite now converts the CIEBased color space to an ICCBased
    space if possible. (devs.mak [1.48]: 2001/12/13 18:24:05 lpd)
    	- Fix for #474544. Corrects inability to convert valid DeviceN tint
    transform functions into type 4 functions. Valid operator names were not
    being recognized unless the tint transform function had been bound. One of
    two fixes required for this problem. Customer #710. (int.mak [1.57]:
    2002/01/11 05:09:22 dancoby)
    	- Fix for #474544. This is the second of two fixes required for this
    problem. This fix creates a type 0 function which implements a "color cube"
    for those tint transform functions which cannot be converted into a type 4
    function. Customer #710. Note: There is one more revision planned for this
    effort. This revision will make the buildcolorcube operator into a more
    general buildsampledfunction. This will allow its use in other situations.
    (int.mak [1.58]: 2002/01/17 05:53:40 dancoby)
    	- Disables optimization on OpenVMS, because some OpenVMS C compilers
    produce incorrect code for gdevpsfx.c. Fixes SourceForge #508722.
    (openvms.mak [1.19], openvms.mmk [1.14]: 2002/02/05 19:54:14 lpd)
    	- Fix 3 of 3 for #474544 "Core dump - shfill error with DeviceN". 1.
    Recognizes already encapsulated tint transform functions. 2. Generalizes the
    color cube logic for use in other situations. 3. Uses the domain of the
    alternate color space for the range of the tint transform function.
    (int.mak [1.60]: 2002/02/06 02:35:11 dancoby)
    	- ps2pdf14 was not being installed by unixinst.mak. Fixes
    SourceForge bug #508607. (unixinst.mak [1.22]: 2002/02/06 07:16:17 jackiem)
    	- Fixes cvs2hist.py to be branch-aware, changing log selection
    policy from "all logs more recent than the date of the last tag" to "all
    logs along the current branch more recent than the reference tag given in
    the -j option". (toolbin/cvs2hist.py [1.10]: 2002/02/06 21:11:54 raph)
    	- pkmraw device was not built by Windows makefile, but it is
    required for regression testing. (msvc32.mak [1.23]: 2002/02/18 11:22:17
    igor)
    	- ijs.mak had the wrong license header (ijs.mak [1.3]: 2002/02/19
    23:59:34 giles)
    	- reverts the license of ijs.mak to AFPL; the previous change was
    intended for the GPL branch. (ijs.mak [1.4]: 2002/02/20 00:16:00 giles)
    	- check_docrefs didn't pass the gsroot parameter down far enough.
    (toolbin/tests/check_docrefs.py [1.3]: 2002/02/20 07:10:14 lpd)
    	- The Ghostscript test class didn't initialize the new member
    gsoptions. (bug introduced by Windows portability patch)
    (toolbin/tests/gstestgs.py [1.3]: 2002/02/20 07:14:35 lpd)
    	- The check_dirs test script still tried to check
    toolbin/regression, which no longer exists.
    (toolbin/tests/check_dirs.py [1.3]: 2002/02/21 22:19:03 lpd)
    	- The check_source test script didn't properly skip src/gconf.h, and
    it was too strict about the form of double-inclusion protection for header
    files. (toolbin/tests/check_source.py [1.3]: 2002/02/21 22:22:49 lpd)
    	- Add LICENSE file and the few files generated by autogen.sh to the
    allowed files in check_dir.py. (toolbin/tests/check_dirs.py [1.5]:
    2002/02/22 00:34:54 jack)
    	- The check_docrefs test script skipped over directories named by
    links. (toolbin/tests/check_docrefs.py [1.6]: 2002/02/22 02:42:35 lpd)
    	- Include gs_resmp.ps into the prelude with ADDMOD rather than
    .runlibfile (suggested by Raymond J. Johnston), and increase MSVC compiler
    heap for building gs_init.c with COMPILE_INITS=1. Source Forge bug "[ 526192
    ] Broken COMPILE_INITS". (int.mak [1.64], msvccmd.mak [1.9]: 2002/03/06
    08:55:16 igor)
    	- Second attempt to fix COMPILE_INITS=1. This statically embeds all
    gs_*.ps files, xlatmap and FAPIconfig. Source Forge bug "[ 526192 ] Broken
    COMPILE_INITS". (int.mak [1.65]: 2002/03/07 10:52:06 igor)
    	- Definition for gsiodisk.$(OBJ) was multiply defined. Remove the
    one that is not dependent on the diskn.dev FEATURE. (lib.mak [1.66]:
    2002/03/15 06:25:13 ray)
    	- remove -fno-common from the standard gcc LDFLAGS. It is only
    required at compile time and doesn't need to be passed to the linker.
    (macosx.mak [1.7], unix-gcc.mak [1.29]: 2002/03/28 23:12:09 giles)
    	- base release date on UTC rather than local time
    (version.mak [1.43]: 2002/03/29 00:36:20 giles)
    	- use UTC universally in the prerelease check script to avoid
    spurious errors due to timezone differences (toolbin/pre.tcl [1.6]:
    2002/03/29 00:44:34 giles)
    	- gsfont.h didn't define gs_matrix as an opaque type, causing
    clients of gsfont.h to include gsmatrix.h unnecessarily. (lib.mak [1.68]:
    2002/03/29 00:48:21 lpd)
    	- Makes pathname manipulation in check_dirs.py and check_docrefs.py
    more portable and robust. (toolbin/tests/check_dirs.py [1.6],
    toolbin/tests/check_docrefs.py [1.7]: 2002/03/29 02:32:54 raph)
    	- Change spaces at start of rule to a single tab required by some
    makes. (winint.mak [1.14]: 2002/04/02 16:27:56 ray)
    	- Correct vdtrace.h dependencies. This eliminates >300 lines of
    output from the gsmake.tcl makefile check tool. (int.mak [1.68],
    lib.mak [1.69]: 2002/04/02 19:34:37 ray)
    	- .dev was left off of uniprint.dev in a DEVICES macro
    (msvc32.mak [1.29]: 2002/04/03 20:14:28 ray)

    Updates version number to 7.10 to indicate that this is now the development
    branch. (version.mak [1.37]: 2001/10/20 09:25:22 raph)

    Changes all procedures for getting glyph outline data to return a structure
    that includes memory management information. This is a
    NON-BACKWARD-COMPATIBLE change to both implementors and clients. It corrects
    a serious design error: formerly these procedures encoded memory management
    information in their return code, which was obscure and error-prone.

    Adds support for compilation against a standard shared libjpeg. It is
    believed that non-baseline compliant DCTEncoded data, permitted by early
    versions of postscript, is now extremely rare and the prohibition against
    SHARE_JPEG=1 may reasonably be removed. The autoconf build will prefer a
    local copy of the jpeg source, in which case the D_MAX_BLOCKS_IN_MCU patch
    will still be applied. If no such local copy is found, it will try to find a
    shared library on the system. For all unix builds, if $(JSRCDIR)/jmemsys.h
    cannot be found, we define DONT_HAVE_JMEMSYS_H and include our own versions
    of the libjpeg memory manager prototypes. The default allocator in the
    shared library is overridden by the ghostscript one at link-time. While this
    may be implementation-dependent, it appears to function as desired on at
    least GNU/Linux and Solaris. Also changes the autoconf build to prefer local
    zlib and libpng source, and cleans up some variable names.

    Fixes problems:
    	- There were 3 unused declarations of the variable 'buf'.
    (ziodevsc.c [1.4]: 2001/11/22 04:57:21 lpd)
    	- remove unnecessary include in dxmainc.c. (dxmainc.c [1.5]:
    2001/11/25 07:52:55 giles)
    	- ps2ascii was broken (probably for a long time) because it still
    used NOBIND rather than DELAYBIND. Fixes SourceForge #485029.
    (lib/ps2ascii [1.4], lib/ps2ascii.bat [1.4], lib/ps2ascii.cmd [1.2],
    lib/ps2ascii.ps [1.4]: 2001/12/08 15:43:07 lpd)

    gp_macio.c [1.3]: 2002/01/09 21:04:20 giles)
    	- On IA64 CPUs, objects were only aligned on 8-byte boundaries, not
    16-byte. (It may be that only jmpbuf structures actually need 16-byte
    alignment, but gcc and glibc malloc align all objects that way.) Fixes
    SourceForge bug #502866. Also cleans up some minor coding issues in
    genarch.c. (genarch.c [1.3]: 2002/01/16 16:09:20 lpd)
    	- Most of the calls of gs_[main_]init1 didn't check the return value
    for errors. (gserver.c [1.4]: 2002/01/18 00:43:10 lpd)
    	- Incorporate patch from Tim Waugh of RedHat to allow ps2pdfwr to
    correctly process files with spaces in their names. Peter's earlier fix
    missed a few enclosing "'s for output files. Fixes Sourceforge bug #505338.
    (lib/ps2pdfwr [1.7]: 2002/01/22 20:25:44 jackiem)
    	- Improve security in a (mostly) backward compatible fashion adding
    more flexible file access paths (PermitFile...) as user paramters and adding
    the facility to return to NOSAFER mode after running jobs (files/procedures)
    in SAFER mode. This should address SF bug #474582 and eliminate the need for
    the RedHat PARANOIDSAFER patch. (gp_macio.c [1.4], gp_ntfs.c [1.6],

    	- Extra (old) parameters to gp_file_name_concat_string removed.
    (gp_ntfs.c [1.7]: 2002/02/01 08:03:46 rayjj)
    	- File enumeration on VMS doesn't enumerate "*" as all files,
    needing "*.*" similar to gp_dosfe.c. PostScript FONTPATH scanning and PCL
    font loading failed prior to this fix. Filenames that already have a "."
    prior to the trailing "*" are not modified. (gp_vms.c [1.9]: 2002/02/06
    01:07:54 rayjj)
    	- Typos (" used when ' was needed) fixed. So much for desk checking
    :-( (gp_vms.c [1.10]: 2002/02/08 04:37:56 rayjj)
    	- Fixes pdf2dsc to open input file before .setsafe, so that it works
    even when SAFER locks down read file access. (lib/pdf2dsc.ps [1.4]:
    2002/02/13 17:28:08 raph)
    	- pdfopt didn't handle pages with no Contents, and didn't handle
    files in which any objects (such as resources) were referenced from both the
    first page and later pages. Also adds more tracing output to pdfopt (with
    -dPDEBUG). Fixes SourceForge #516628. (lib/pdfopt.ps [1.11]: 2002/02/19

## Drivers

    Fixes problems:
    	- Fixes a %ld format with an int argument. (gdevpsu.c [1.8]:
    2001/11/22 05:10:01 lpd)
    	- Setting any of the pdfwrite xxxProfile "distiller" parameters
    caused a garbage collection error. (gdevpsdp.c [1.9]: 2001/11/25 01:02:51
    lpd)
    	- some files were missing the RCS 'Id' line with the last
    modification date. partial fix for Sourceforge bug #500922.

    gdevmacxf.c [1.3], gdevphex.c [1.4]: 2002/01/09 21:04:20 giles)
    	- Don't signal invalidacces if the OutputFile parameter is set to
    the current value as would be done by 'currentpagedevice setpagedevice'.
    (gdevcgm.c [1.4], gdevmac.c [1.4]: 2002/01/15 04:44:09 rayjj)
    	- epswrite generates "grestore gsave" while changing a clipping
    path, so the internal graphic state and the output document's graphic state
    become unsynchonized. Particularly this looses the current color. Source
    Forge bug [ #502830 ] pdf2ps - bad color of objects (gdevps.c [1.20]:
    2002/01/29 05:57:49 igorm)
    	- Removes broken x11alpha driver, and installs an alias for x11
    under that name, with default parameters changed to support antialiasing.
    Fixes SourceForge bug #505692. (gdevx.c [1.9], gdevxalt.c [1.3]: 2002/01/30
    20:08:41 raph)
    	- The previous version of src/gdevps.c was checked in with
    DOS/Windows (^M^J) EOLs rather than Unix (^J) EOLs, causing some C compilers
    to reject it. (gdevps.c [1.21]: 2002/02/05 05:09:08 lpd)
    	- psdf_end_binary didn't convert the stream status to an error code,
    possibly causing incorrect error reporting. (gdevpsdu.c [1.11]: 2002/02/12
    22:00:39 lpd)
    	- Many files lacked double-inclusion protection, or implemented it
    incorrectly. (gdevbjcl.h [1.3], gdevmacpictop.h [1.3], gdevmacttf.h [1.3],
    png_.h [1.3]: 2002/02/20 01:32:47 lpd)
    	- Changes XPutImage to use xdev->vinfo->depth rather than
    xdev->color_info.depth. These are the same in all cases except a visual
    depth of 15, in which the latter is 16. (gdevx.c [1.10]: 2002/02/20 19:39:02

    	- improve pswrite with compatibility to interpreters which don't
    consume ASCII85Decode EOD when reader stops immediately before it. Source
    Forge bug #525044 "pswrite incompatible with some RIPs". Thanks to Paul

    Adds a reference to the v7.xx History file. (gdevmacxf.c [1.2]: 2001/10/24
    22:33:38 giles)

    Changes uses of 'defined' as an identifier to 'is_defined', since 'defined'
    is a (non-standard) reserved word in gcc 2.96. (Patch from Red Hat.)
    (gdevcdj.c [1.6]: 2001/11/07 07:48:57 lpd)

    Updates pdfwrite to match Acrobat Distiller 5 more closely: adds
    OffOptimizations and PreserveEPSInfo parameters; adds /ebook value for
    PDFSETTINGS; changes some of the DCTEncode parameter values for
    auto-filtered images; adds CreationDate and ModDate in Info dictionary;
    always subsets non Type 1 fonts. (gdevpsdi.c [1.16]: 2001/12/09 00:07:57

    Remove C++ // comment from C file. (gdevwdib.c [1.4]: 2001/12/19 22:13:08
    ghostgum)

    Improve security for device related access to the file system and to pipes
    by allowing the dangerous parameters to be locked (for example, OutputFile).
    The locking is performed after command line parameters are established.
    Locking is not turned on by default as a result of this change, but
    -d.LockSafetyParams=true can be added to the command line to accomplish
    this. Related to SF bug #474582 (sort of). (gdevcgm.c [1.3],
    gdevmac.c [1.2]: 2001/12/22 00:44:01 rayjj)

    Updates the extension of the golfer and tiger example files to '.eps' in the
    install target. Also updates some documentation in source file comments.

## PDF writer

    Fixes problems:
    	- Repeated use of the same color space wrote multiple ColorSpace
    resources rather than a single one. Fixes the pdfwrite part of SourceForge
    bug #475219: separate changes to pdf_draw.ps and pdf_ops.ps fix the
    interpreter part of the bug. (gdevpdfc.c [1.18]: 2001/11/06 17:34:30 lpd)
    	- Reading from /dev/random can cause long blocking on Solaris 8, so
    we only attempt it (on all systems) if non-blocking I/O is available, and we
    try /dev/urandom first. Fixes SourceForge #482048. (gdevpdf.c [1.39]:
    2001/11/21 22:14:22 lpd)
    	- CIE color conversion could be very inaccurate if it didn't use
    interpolation when cached sampled values were near zero. This fix detects
    numerically sensitive areas and uses interpolation (which is computationally
    expensive) only in those areas. Fixes SourceForge #465921.
    (gdevpdfc.c [1.19]: 2001/12/09 00:03:37 lpd)
    	- For images specified in general CIEBased color spaces, pdfwrite
    would divide the image into tiny rectangles. If the output level is PDF 1.3
    or higher, pdfwrite now converts the CIEBased color space to an ICCBased
    space if possible. (gdevpdfc.c [1.20], gdevpdfc.h [1.1], gdevpdfk.c [1.1]:
    2001/12/13 18:24:05 lpd)
    	- the prototype for pdf_text_process was in a .c file rather than a
    .h file. (gdevpdff.h [1.12], gdevpdft.c [1.37]: 2002/01/15 23:07:02 lpd)
    	- pdfwrite incorrectly handled Metrics[2] and CDevProc by writing
    Widths that differed from the widths in the underlying font. pdfwrite now
    positions characters individually in this case, like Acrobat Distiller.
    Fixes SourceForge #495414. (gdevpdff.c [1.23], gdevpdff.h [1.13],
    gdevpdfs.c [1.8]: 2002/01/17 05:13:24 lpd)
    	- Work around an apparent Acrobat Reader 5 bug -- it gives an error
    for images with a color-key mask, at least for 1-bit-deep images using an
    Indexed color space -- by converting the image to an ordinary masked image.
    Fixes a PCL->PDF problem reported by a customer. (gdevpdfi.c [1.25]:
    2002/01/17 17:01:38 lpd)
    	- Setting the parameters for a stroked font could reset other text
    state parameters, causing 'Font not set' and other errors from Acrobat.
    Fixes SourceForge bug #505011. (gdevpdfs.c [1.9]: 2002/01/24 16:37:53 lpd)
    	- pdfwrite often gave an error if a name with embedded special
    characters was a key or value in a pdfmark dictionary. Fixes SourceForge
    #505877. (gdevpdfr.c [1.5]: 2002/01/29 02:54:43 lpd)
    	- pdfwrite could output Indexed color spaces with more than 256
    entries, or images with more than 8 bits per component, neither of which PDF
    supports. This patch causes the latter to revert to the
    millions-of-tiny-rectangles representation, which is not adequate in the
    long run, but is at least valid output. Fixes SourceForge #513910, for the
    moment. (gdevpdfc.c [1.21], gdevpdfi.c [1.26]: 2002/02/11 16:26:20 lpd)
    	- pdf_end_image_binary didn't propagate all error indications to its
    caller. (gdevpdfj.c [1.8]: 2002/02/12 21:55:31 lpd)
    	- (1) real_widths were missed in public_st_pdf_font; (2)
    pdf_finalize_font_descriptor was called twice (form pdf_font_notify_proc and
    from pdf_write_font_resources), if a font is garbage-collected after
    pdf_close. Source Forge bug "[ 531983 ] ps2pdf coredumps on this ps file".

## PDF Interpreter

    Fixes problems:
    	- Setting the same PDF color space repeatedly generated new
    PostScript color spaces, stressing the garbage collector. Fixes the PDF
    interpreter part of SourceForge bug #475219: a separate change to gdevpdfc.c
    fixes the pdfwrite part of this bug. (lib/pdf_draw.ps [1.37],

    	- showpagecontents needs to be wrapped in a gsave/grestore as rev
    1.23 indicates, but we can't wrap around the .pushpdf14devicefilter or the
    grestore will change the device back to the original and clear the page.
    Fixes SourceForge bug #476821 for Artifex customer 870. Also clean up some
    non-standard indentation in the area. (lib/pdf_main.ps [1.36]: 2001/11/15
    04:30:25 rayjj)
    	- T* applied the leading horizontally when using a font in vertical
    writing mode, but the PDF Reference says the leading is always applied
    vertically. (lib/pdf_ops.ps [1.19]: 2001/12/22 07:24:50 masata-y)
    	- Fix for "[ #505041 ] /typecheck in --setcolor--". Customer 150. An
    error in counting the number of values by the PDF interpreter was causing an
    incorrect number of values to be sent to setcolor. This in turn caused a
    typecheck. (lib/pdf_main.ps [1.37]: 2002/01/30 00:43:29 dancoby)
    	- Some PDF files don't have balanced q/Q operators (gsave/grestore)
    that left extra dicts on the dictstack. Save the dictstack depth before the
    page and pop any left over elements. Fix for SF #495088 for customer #870.
    (lib/pdf_main.ps [1.38]: 2002/02/05 20:50:25 rayjj)
    	- Extra dict was left on the ostack by rev 1.38 (introduced when
    fixing SF bug #495088). Also allow bad images to be skipped (with a warning
    message) as Adobe Reader does. Make PDF format error messages more
    consistent. Fixes SF bug #513902 for Artifex customer #10.
    (lib/pdf_draw.ps [1.38], lib/pdf_main.ps [1.40]: 2002/02/08 04:34:14 rayjj)
    	- Another improvement for the hack in 'getfontmetrics', which deals
    with encodings where the same character appears more than once. TeX-1.0a
    creates Differences with multiple appearances of 'hyphen' character, some of
    which specify zero width. Source Forge bug #517474 "Problem with hyphen in
    PDF using Minion". See also #444366 and #467492. (lib/pdf_font.ps [1.27]:

    	- PDF files that specify the same embedded font file many times
    would reload the FontFile each time, potentially severely impacting

## Interpreter

    Fixes problems:
    	- Fixes a comment: invoking definefont on a dictionary that already
    has a FID entry is, in fact, legal in LanguageLevel 2 and above.
    (zbfont.c [1.9]: 2001/10/29 23:49:57 lpd)
    	- The change v.1.14 had broken the branch of the font loader, which
    works for the case of unequal font names in the font file and in the font
    map. SourceForge bug 474581. Also cleans up potential stack imbalance
    present since 1.1. (lib/gs_fonts.ps [1.15]: 2001/11/15 08:27:37 igorm)
    	- "Native float" binary tokens and homogenous number arrays failed
    to ignore the big/little-endian bit in the format field, causing them to
    (usually) read incorrectly on little-endian systems. (bug reported by Pierre
    Arnaud) (ibnum.c [1.3], ibnum.h [1.3]: 2001/11/16 22:30:40 lpd)
    	- If the initial device couldn't be opened, the error message
    indicating this wasn't being printed, because of a missing 'flush'. Fixes

    	- Fixes a compiler warning and several minor formatting
    inconsistencies. (zmedia2.c [1.4]: 2001/11/22 05:04:24 lpd)
    	- The private procedure gs_get_colorname_string was not declared
    private. (zcsdevn.c [1.6]: 2001/11/22 05:38:27 lpd)
    	- The private procedure dsc_is_section was not declared dsc_private.

    being deprecated. (lib/gs_init.ps [1.43]: 2001/11/22 18:48:51 lpd)
    	- Ghostscript didn't match a bug in Adobe's interpreters, which
    byte-swap native reals in binary object sequences iff the native real format
    is IEEE. (The PLRM says native reals should never be byte-swapped.) Fixes
    SourceForge bug #489478. (ibnum.h [1.4], iscanbin.c [1.6]: 2001/12/07

    	- Repairs code problems with the fix for bug #224056: non-re-entrant

    #include. (zcolor2.c [1.5]: 2001/12/07 05:41:59 lpd)
    	- CIE color conversion could be very inaccurate if it didn't use
    interpolation when cached sampled values were near zero. This fix detects
    numerically sensitive areas and uses interpolation (which is computationally
    expensive) only in those areas. Fixes SourceForge #465921. (zcie.c [1.6],
    zcrd.c [1.3]: 2001/12/09 00:03:37 lpd)
    	- WMode 1 did not work for CIDFontType 2. SourceForge bug #91713.
    Patch from Mr. Toshiya Suzuki. (zchar42.c [1.4]: 2001/12/12 16:45:09 igorm)
    	- The constraint for FontBBox to be non-zero was not conforming and
    now it is removed. Suggested by L. Peter Deutsch. (bfont.h [1.4],
    zbfont.c [1.10], zfcid0.c [1.10], zfcid1.c [1.6]: 2001/12/19 11:49:44 igorm)
    	- The previous fixes for writing binary objects were incorrect,
    probably because an incorrect comment misled the author. Fixes SourceForge
    #490914. (lib/gs_btokn.ps [1.6]: 2002/01/01 23:08:28 lpd)
    	- Dictionaries in binary object sequences (a non-standard feature)
    could cause an invalidaccess error if any of the keys or values were names.
    (iscanbin.c [1.7]: 2002/01/01 23:08:56 lpd)
    	- Some gsapi functions were not passing the user_errors argument to
    the corresponding gs_main_run_string_* functions, and instead, these
    functions were passing 0. (iapi.c [1.3]: 2002/01/03 20:09:46 jackiem)

    	- ifont.h requires gsmatix.h and gxfont.h for clean compilation. Not
    having them was a warning on gcc, but an error on Borland CBuilder 5.5.
    Thanks to Rod Webster for the fix. Closes Sourceforge bug #474246.
    (iccfont.c [1.3]: 2002/01/09 21:48:00 giles)
    	- Fix for #474544. Corrects inability to convert valid DeviceN tint
    transform functions into type 4 functions. Valid operator names were not
    being recognized unless the tint transform function had been bound. One of
    two fixes required for this problem. Customer #710. (ifunc.h [1.4],

    bug #499903. (dwmain.c [1.7], dwmainc.c [1.9]: 2002/01/12 19:49:00 igorm)
    	- pdfwrite incorrectly handled Metrics[2] and CDevProc by writing
    Widths that differed from the widths in the underlying font. pdfwrite now
    positions characters individually in this case, like Acrobat Distiller.
    Fixes SourceForge #495414. (zchar1.c [1.9]: 2002/01/17 05:13:24 lpd)
    	- Fix for #474544. This is the second of two fixes required for this
    problem. This fix creates a type 0 function which implements a "color cube"
    for those tint transform functions which cannot be converted into a type 4
    function. Customer #710. Note: There is one more revision planned for this
    effort. This revision will make the buildcolorcube operator into a more
    general buildsampledfunction. This will allow its use in other situations.

    	- Improve security in a (mostly) backward compatible fashion adding
    more flexible file access paths (PermitFile...) as user paramters and adding
    the facility to return to NOSAFER mode after running jobs (files/procedures)

    Improve security for device related access to the file system and to pipes
    by allowing the dangerous parameters to be locked (for example, OutputFile).
    The locking is performed after command line parameters are established.
    Locking is not turned on by default as a result of this change, but
    -d.LockSafetyParams=true can be added to the command line to accomplish
    this. Related to SF bug #474582 (sort of). (lib/gs_setpd.ps [1.9],

    This is an improvement from L. Peter Deutsch in the logic which tests the
    size of the amount of data required for a function to be sampled. This
    eliminates a possible math overflow and also tests for a negative size
    value. This is part of bug 474544. (zfsample.c [1.2]: 2002/02/21 07:42:23

    Removes a compiler warning on the 4th parameter to valid_cube_size(). Added
    const conditional to the parameter. (zfsample.c [1.3]: 2002/02/21 08:12:35

    Adds support for compilation against a standard shared libjpeg. It is
    believed that non-baseline compliant DCTEncoded data, permitted by early
    versions of postscript, is now extremely rare and the prohibition against
    SHARE_JPEG=1 may reasonably be removed. The autoconf build will prefer a
    local copy of the jpeg source, in which case the D_MAX_BLOCKS_IN_MCU patch
    will still be applied. If no such local copy is found, it will try to find a
    shared library on the system. For all unix builds, if $(JSRCDIR)/jmemsys.h
    cannot be found, we define DONT_HAVE_JMEMSYS_H and include our own versions
    of the libjpeg memory manager prototypes. The default allocator in the
    shared library is overridden by the ghostscript one at link-time. While this
    may be implementation-dependent, it appears to function as desired on at
    least GNU/Linux and Solaris. Also changes the autoconf build to prefer local
    zlib and libpng source, and cleans up some variable names. (sjpegc.c [1.7]:

## Library

    Fixes problems:
    	- Change show_enum pointer enumeration to properly enumerate
    underlying gs_text_enum structure. (gxchar.c [1.6]: 2001/10/26 16:28:02
    raph)
    	- Image DataSource procedures that did save/restore would clear the
    tile cache which was not detected in image_render_mono resulting in images
    being painted with (mostly) all black when the device was a halftoned device
    e.g. pcxmono or tiffg3. Check for vailidity of the ht_cache and re-init the
    image color clues if not valid. Also improve performance by preventing
    restore from always clearing the ht_cache. Fixes SourceForge bug #436897 for
    Artifex customer #710. (gsstate.c [1.12], gxht.c [1.3], gximage.h [1.3],
    gximono.c [1.3], gxipixel.c [1.3], gzht.h [1.5]: 2001/11/06 22:40:05 rayjj)
    	- Trailing comma in structure (compile error on AIX).
    (gxfcmap.h [1.9]: 2001/11/07 18:00:09 rayjj)
    	- Fix for 473305 and a revised fix for 422534. The fix for 422534
    caused a problem detected by the regression testing. This was found with
    test file 035-01.ps. Both problems were caused by an error in the logic for
    comparing two halftones for equality. This logic is used to determine which
    the halftone cache needs to be reloaded. In both cases, non equal halftones
    were being considered equal. (gsdcolor.h [1.4], gxcht.c [1.4],
    gxclrast.c [1.10], gxdcolor.c [1.4]: 2001/11/12 22:15:19 dancoby)

    (gxshade1.c [1.10]: 2001/11/22 05:01:40 lpd)
    	- Removes 2 undefined variables. (gsdevice.c [1.12]: 2001/11/22
    05:05:41 lpd)
    	- Removes an unused variable. (gsfcmap.c [1.15]: 2001/11/22 05:14:55

    (gsfont.c [1.5], gxfcache.h [1.3]: 2001/11/22 05:56:51 lpd)
    	- CIE color conversion could be very inaccurate if it didn't use
    interpolation when cached sampled values were near zero. This fix detects
    numerically sensitive areas and uses interpolation (which is computationally
    expensive) only in those areas. Fixes SourceForge #465921. (gscie.c [1.6],
    gscie.h [1.5], gsciemap.c [1.8], gscrd.c [1.3]: 2001/12/09 00:03:37 lpd)
    	- Image Type 4 images processed with the Interpolate turned on (as
    from -dDOINTERPOLATE) left an uninitialized variable that could cause
    extensive slowdown. Fix for SourceForge bug #491308 for Artifex customer
    671. (gxiscale.c [1.3]: 2001/12/14 19:02:27 rayjj)
    	- Don't signal invalidacces if the OutputFile parameter is set to
    the current value as would be done by 'currentpagedevice setpagedevice'.
    (gdevprn.c [1.7]: 2002/01/15 04:44:09 rayjj)
    	- On IA64 CPUs, objects were only aligned on 8-byte boundaries, not
    16-byte. (It may be that only jmpbuf structures actually need 16-byte
    alignment, but gcc and glibc malloc align all objects that way.) Fixes
    SourceForge bug #502866. Also cleans up some minor coding issues in
    genarch.c. (gsmalloc.c [1.4], gxobj.h [1.3]: 2002/01/16 16:09:20 lpd)
    	- pdfwrite incorrectly handled Metrics[2] and CDevProc by writing
    Widths that differed from the widths in the underlying font. pdfwrite now
    positions characters individually in this case, like Acrobat Distiller.
    Fixes SourceForge #495414. (gxfont.h [1.6]: 2002/01/17 05:13:24 lpd)
    	- The recent fix for #502866 required malloc to align blocks at
    least as stringently as the compiler requires. Even though the ANSI C
    specification appears to require this, and Ghostscript relies on it, Dan
    reports that some C implementation doesn't do it. Additional patching to
    deal with this problem will undoubtedly be required.... (gsmalloc.c [1.5]:
    2002/01/18 00:31:25 lpd)
    	- The check for unaligned return values from malloc still had a bug.
    (gsmalloc.c [1.6]: 2002/01/18 18:27:08 lpd)
    	- MSVC's malloc on x86 only aligns blocks mod 4, even though the
    compiler aligns 'double' members of structures mod 8. Documents this fact in
    the relevant places in the Ghostscript code, and removes the check that was
    causing gsmalloc.c to produce warning messages. (gsmalloc.c [1.7],
    gsmemory.h [1.4], gsmemraw.h [1.4], gxbitmap.h [1.3], gxobj.h [1.4]:
    2002/01/22 08:04:28 lpd)
    	- Improve security in a (mostly) backward compatible fashion adding
    more flexible file access paths (PermitFile...) as user paramters and adding
    the facility to return to NOSAFER mode after running jobs (files/procedures)

    	- When pdfwrite embedded a TrueType font with a generated format 6
    cmap, it incorrectly added the character bias (0xf000) to the "first
    character code" entry in the cmap sub-table. Fixes SourceForge #434707 and
    probably some others. This fix also adds a set of compile-time options for
    forcing embedded TTFs into particular formats for debugging.

    	- Prevent Type2 fonts from needing more than 48 ostack elements.
    Patch provided by Toshiya Suzuki-san (mpsuzuki). Also add checking to
    prevent fonts that push more than 48 elements on the ostack from overflowing
    the array (could caused SEGV). Fix for SourcForge bug #497537.

    	- The cached effective_clip_id was being set to the clip_id of the
    clip_path, ignoring the viewclip path in some cases. Set the 'id' to
    correctly reflect the path in effective_clip_path. Fixes SF bug #458769 for
    Artifex customer #1130. (gspath.c [1.3]: 2002/02/05 00:29:59 rayjj)
    	- Prevent large transparency buffer allocations from overflowing
    unsigned int. Could lead to SEGV or buffer overflow. Also fix up some return
    code handling when allocations fail in PDF 1.4 transparency logic. Fixes SF
    bug #511914 for Artifex customer #680. (gdevp14.c [1.5]: 2002/02/05 08:13:50

    	- gx_begin_image3x_generic passed uninitialized data to
    gs_cspace_init_DevicePixel when Shape.MaskDict was absent, causing a garbage

    documentation. (gstype2.c [1.16]: 2002/02/22 23:32:41 lpd)
    	- Makes the standard memory manager scan all chunks, not just the
    currently open one, for available free space. This is a long-planned,
    long-overdue improvement that can improve memory utilization dramatically.
    (gsalloc.c [1.14]: 2002/02/22 23:39:20 lpd)
    	- Prevent image interpolation if the target device has less than 4
    bits per component. This prevents interpolation from causing 'noise'
    (stripes, shadows, etc.) in the output when the device is halftone dithered.

    Changes all procedures for getting glyph outline data to return a structure
    that includes memory management information. This is a
    NON-BACKWARD-COMPATIBLE change to both implementors and clients. It corrects
    a serious design error: formerly these procedures encoded memory management
    information in their return code, which was obscure and error-prone.

    Refactors the CIEBased color mapping code slightly to make the CIE => XYZ

    Improve security for device related access to the file system and to pipes
    by allowing the dangerous parameters to be locked (for example, OutputFile).
    The locking is performed after command line parameters are established.
    Locking is not turned on by default as a result of this change, but
    -d.LockSafetyParams=true can be added to the command line to accomplish
    this. Related to SF bug #474582 (sort of). (gdevprn.c [1.6],

## Other

    Fixes problems:
    	- the configure script was setting ZSRCDIR to the empty string in
    the case where SHARE_ZLIB=1, causing a syntax error on the libpng command
    line. It is now set to a harmless default (configure.ac [1.2]: 2002/01/06
    00:12:03 giles)
    	- prefer 'src' over '.' for the spurious local include line for
    zlib. Thanks to Peter Deutsch for the suggestion. (configure.ac [1.3]:
    2002/01/09 20:20:27 giles)
    	- some files were missing the RCS 'Id' line with the last
    modification date. partial fix for Sourceforge bug #500922. (gp_mac.h [1.2],
    macsysstat.h [1.2], macsystypes.h [1.2], vms_x_fix.h [1.2]: 2002/01/09
    21:04:21 giles)
    	- corrects the name of the autoconf generated makefile for the
    purpose of dependencies (Makefile.in [1.3]: 2002/02/01 04:11:46 giles)
    	- Many files lacked double-inclusion protection, or implemented it
    incorrectly. (gsdll.h [1.4], vms_x_fix.h [1.3]: 2002/02/20 01:32:47 lpd)
    	- Fixes the gdevx.o command line in the case when AC_PATH_X sets
    x_includes to the empty string. Fixes SF #530429. (Makefile.in [1.6],
    configure.ac [1.7]: 2002/03/28 19:35:03 raph)
    	- Uses a default 'src' setting for PSRCDIR in the autoconf build
    with shared libpng, as we do with zlib, preventing compiler confusion from
    empty -I lines. Partial fix for SF bug #514898. (configure.ac [1.8]:
    2002/03/28 19:52:28 giles)
    	- improves X11 path settings in the autoconf build. We use
    AC_PATH_XTRA instead of the previous "is it null" hack with AC_PATH_X. The
    new macro also defines some additional libraries that may need to be
    included. We currently don't use this information. (Makefile.in [1.7],
    configure.ac [1.9]: 2002/03/28 20:40:25 giles)
    	- remove -fno-common from the standard gcc LDFLAGS. It is only
    required at compile time and doesn't need to be passed to the linker.
    (Makefile.in [1.8]: 2002/03/28 23:12:09 giles)
    	- verify that our default collection of compiler switches
    (gcc-specific) work before using them. This allows the autoconf build to
    work with non-gcc compilers. Completes the fix for SF Bug #514898.
    (Makefile.in [1.9], configure.ac [1.10]: 2002/03/28 23:15:53 giles)
    	- remove -fno-common from the default LDFLAGS (again) This was
    inadvertently reverted in the previous revision. (Makefile.in [1.10]:
    2002/03/29 22:04:58 giles)
    	- removes -Wtraditional for the default gcc compiler flags for the
    autoconf build as well. (configure.ac [1.11]: 2002/03/29 22:05:54 giles)
    	- removes gcc-specific compiler flags from the autoconf makefile,
    including the -fomit-frame-pointer optimization. Replaces the workaround for
    const not working in gcc 2.7 with the more general autoconf macro
    AC_C_CONST. Lists the defines generated by the configure script for
    reference in the Makefile, but doesn't make use of them.

    Adds support for compilation against a standard shared libjpeg. It is
    believed that non-baseline compliant DCTEncoded data, permitted by early
    versions of postscript, is now extremely rare and the prohibition against
    SHARE_JPEG=1 may reasonably be removed. The autoconf build will prefer a
    local copy of the jpeg source, in which case the D_MAX_BLOCKS_IN_MCU patch
    will still be applied. If no such local copy is found, it will try to find a
    shared library on the system. For all unix builds, if $(JSRCDIR)/jmemsys.h
    cannot be found, we define DONT_HAVE_JMEMSYS_H and include our own versions
    of the libjpeg memory manager prototypes. The default allocator in the
    shared library is overridden by the ghostscript one at link-time. While this
    may be implementation-dependent, it appears to function as desired on at
    least GNU/Linux and Solaris. Also changes the autoconf build to prefer local
    zlib and libpng source, and cleans up some variable names.

# Version 7.03 (2001-10-20)

This is a fully tested, stable release of Ghostscript. It fixes quite a few issues with 7.02.

Major changes include:

- Integration of icclib 2.0.
- There was at least one embarassing pdfwrite bug, now fixed.
- Significant shading speedups, especially for worst-case files such as Coons01.ps.
- The stdio logic is a lot more robust. 7.02 had some problems, especially with trying to set stdin to non-blocking.
- The usual bug fixes. In particular, regression testing against 7.00 shows only one serious regression (nonsepqxd2distiller.pdf), and numerous progressions.

The following SourceForge bug numbers are currently open: 215256, 219798, 222727, 226477, 405342, 406689, 406979, 407342, 414947, 414985, 415016, 415142, 415170, 416131, 416830, 418241, 421057, 422532, 423838, 427193, 427314, 427347, 428891, 428973, 432040, 432657, 434277, 434707, 436099, 436897, 437285, 438679, 438957, 443745, 444791, 446344, 446672, 448199, 450663, 451456, 452155, 453969, 457838, 458261, 458500, 458769, 458775, 458780, 462221, 465720, 465921, 465936, 468386, 468762, 469518, 472681.

## Procedures

    Fixes problems:
    	- cvs2hist no longer worked in Python 2.1 and later: the regex and
    regsub modules were superseded by re, and append() no longer accepted
    multiple arguments to create a tuple. The fixes are backward compatible for
    all versions of Python from 1.5 on. (toolbin/cvs2hist.py [1.7]: 2001/09/23
    04:45:10 lpd)
    	- The previous update to make cvs2hist use Python's re module rather
    than the obsolete regex and regsub modules didn't change the code to use
    match objects when necessary. Finishes fixing SourceForge #462777.
    (toolbin/cvs2hist.py [1.8]: 2001/09/23 20:43:16 lpd)
    	- Some print statements for debugging were accidentally left in the
    code. (toolbin/cvs2hist.py [1.9]: 2001/09/23 21:05:12 lpd)
    	- Committing in . Modified Files: gs/src/gp_stdia.c
    gs/src/openvms.mmk gs/src/ziodevs.c patches for OpenVMS (openvms.mmk [1.10]:
    2001/09/24 10:47:06 joukj)
    	- Fixes for stdin as a result of using callouts. Use unbuffered
    read, not non-blocking read. Change gp_stdin_read to use file pointer not
    handle. Remove gp_stdin_init since we don't need to set non-blocking. Change
    gp_stdin.c to use fread/fwrite to be more portable. Flush redirected stdout
    correctly. Added casts to fix compiler warnings in dxmain.c. Corrected
    header dependencies. Fixes SourceForge bug #467787. (dvx-tail.mak [1.5],
    macos-mcp.mak [1.3], openvms.mak [1.16], openvms.mmk [1.11], os2.mak [1.19],
    unix-aux.mak [1.5], watc.mak [1.16], winlib.mak [1.12]: 2001/10/12 21:37:08
    ghostgum)
    	- Committing in . Modified Files: gs/src/openvms.mmk OpenVMS needs
    target : sources ^ this space is realy needed. Otherwise MMS/MMK chokes on
    it!!!! (openvms.mmk [1.12]: 2001/10/15 10:24:21 joukj)
    	- When building gsx and gsc, use the GS makefile macro as the shared
    library name to link against, not a hard coded gs. (unix-dll.mak [1.6]:
    2001/10/17 10:11:23 ghostgum)
    	- Removes cheq.ps from list of example files installed.
    (unixinst.mak [1.20]: 2001/10/17 19:48:36 raph)
    	- Updates icclib to version 2.0, and integrates icclib changes. In
    particular, icclib now accesses Ghostscript streams through the clean
    icmFile object interface, rather than previous hack. Removes remnants of
    previous hack, including gs_stdio.h header file and sread() and swrite()
    functions in stream.c. (lib.mak [1.53]: 2001/10/19 21:52:50 raph)
    	- Documentation and version number change in preparation for 7.03
    release. (version.mak [1.36]: 2001/10/20 08:44:31 raph)
    	- Updates default MSVC_VERSION to 6. (msvc32.mak [1.20]: 2001/10/20
    08:45:39 raph)

## Utilities

    Fixes problems:
    	- Committing in . Modified Files: gs/src/gp_stdia.c
    gs/src/openvms.mmk gs/src/ziodevs.c patches for OpenVMS (gp_stdia.c [1.2],
    ziodevs.c [1.4]: 2001/09/24 10:47:06 joukj)
    	- add missing file descriptor variable to stdin function of
    dxmainc.c. Fixes SourceForge bug #465214. (dxmainc.c [1.3]: 2001/09/28
    22:04:03 ghostgum)
    	- If gtk+ GUI can't be initialised, disable display device. This
    allows gsx to be used without an X display. Partial fix for SourceForge bug
    #450933. (dxmain.c [1.5]: 2001/10/12 11:10:37 ghostgum)
    	- Fixes for stdin as a result of using callouts. Use unbuffered
    read, not non-blocking read. Change gp_stdin_read to use file pointer not
    handle. Remove gp_stdin_init since we don't need to set non-blocking. Change
    gp_stdin.c to use fread/fwrite to be more portable. Flush redirected stdout
    correctly. Added casts to fix compiler warnings in dxmain.c. Corrected
    header dependencies. Fixes SourceForge bug #467787. (dxmain.c [1.6],
    dxmainc.c [1.4], gp_stdia.c [1.3], gp_stdin.c [1.2]: 2001/10/12 21:37:08
    ghostgum)
    	- Proposed log message: Fix: Callout implementation of %stdin,
    %stdout and %stderr now correctly allocates the streams in system memory.
    This avoids a crash during garbage collection seen during frequent
    open/close of stderr.. Fixes SourceForge bugs #427316, #442477.
    (ziodevsc.c [1.3]: 2001/10/15 21:44:42 ghostgum)
    	- When using STDIO_IMPLEMENTATION=, call gp_stdin_read with a file
    pointer, not a file handle. (ziodevs.c [1.5]: 2001/10/17 21:12:44 ghostgum)
    	- Use unbuffered read within gtk+ handler instead of using
    non-blocking read. While waiting for stdin, allow gtk main loop to block to
    avoid wasting CPU. (dxmain.c [1.7]: 2001/10/20 08:22:05 ghostgum)

## Drivers

    Fixes problems:
    	- If "distiller" image compression options were changed in the
    middle of a file, the parameter list holding them might not be set back to
    read mode when using them to compress an image, causing an error. Fixes
    SourceForge #464938. (gdevpsdi.c [1.15]: 2001/09/25 22:00:44 lpd)
    	- bmp16 and png16 devices now create 4 bit/pixel bitmaps instead of
    8. bmp256 and png256 devices now use dci values which match the color
    mapping functions. (gdevbmp.c [1.4], gdevpng.c [1.4]: 2001/09/28 22:06:21
    ghostgum)
    	- Don't omit zero length deltas when stroking so that linecap will
    be produced by resulting PS or EPS file. SourceForge bug #466162.
    (gdevps.c [1.19]: 2001/09/28 23:18:46 rayjj)
    	- Fixes for stdin as a result of using callouts. Use unbuffered
    read, not non-blocking read. Change gp_stdin_read to use file pointer not
    handle. Remove gp_stdin_init since we don't need to set non-blocking. Change
    gp_stdin.c to use fread/fwrite to be more portable. Flush redirected stdout
    correctly. Added casts to fix compiler warnings in dxmain.c. Corrected
    header dependencies. Fixes SourceForge bug #467787. (gdevsppr.c [1.5]:
    2001/10/12 21:37:08 ghostgum)
    	- When the display device fails to allocate memory for the bitmap,
    set the memory device width and height to zero to prevent drawing on it.
    Always call the display_size callback to prevent a lockup in the caller, and
    if there is no memory tell the caller that the width and height are zero.
    Add some casts to remove compiler warnings. Fixes SourceForge bug #430879.
    (gdevdsp.c [1.5]: 2001/10/12 21:41:25 ghostgum)
    	- Syncs with hpijs version 0.97, and fixes a documentation bug.
    (gdevhpij.c [1.3]: 2001/10/19 04:20:07 raph)

## PDF writer

    Fixes problems:
    	- pdfwrite didn't set the orig_matrix of standard fonts, sometimes
    causing re-encoded characters to be written with a width of 0. Bug
    introduced by fix for #439474, gdevpdff.c [1.19]. Fixes SourceForge #463400.
    (gdevpdff.c [1.22]: 2001/10/05 05:40:41 lpd)
    	- pdfwrite allowed AutoRotatePages to override DSC comments rather
    than vice versa, and it interpreted "Portrait" in a DSC orientation comment
    as "don't rotate" rather than as "rotate if necessary so that width <
    height." Fixes SourceForge #467259, although the result is not what the
    submitter wanted. (gdevpdf.c [1.38], gdevpdfp.c [1.19], gdevpdfx.h [1.34]:
    2001/10/07 05:33:11 lpd)

## PDF Interpreter

    Fixes problems:
    	- Pop the /None key in the SMask processing of the 'gs' in a PDF 1.4
    document. Fixes SourceForge bug #459647 for Artifex customer Accusoft.
    (lib/pdf_draw.ps [1.35]: 2001/10/05 18:25:16 rayjj)
    	- Enhances -dDEBUG for encrypted PDF files to print strings after
    decryption. (lib/pdf_sec.ps [1.5]: 2001/10/09 20:17:23 lpd)
    	- If LastPage was greater than the number of pages in the document,
    a rangecheck was generated. Instead, limit LastPage (silently) to the number
    of pages in the document. If FirstPage is past end of document, issue a
    warning. Also, if no pages are processed due to FirstPage > LastPage,
    give a clear error message. SourceForge bug #470025.
    (lib/pdf_main.ps [1.35]: 2001/10/12 07:07:54 rayjj)
    	- Changing the hack in PDF font processing, which chooses character
    width with encodings where the same character appears more than once. New
    code takes width for character code which appears in Differences. Source
    Forge bugs #444366, #468389. (lib/pdf_font.ps [1.22]: 2001/10/14 01:28:05
    igorm)
    	- Fix for #471414. Thanks to Leon Bottou for his excellent analysis
    and fix for this problem. Ghostscript was incorrectly handling a PDF shading
    dictionary in which the /Function entry contained an array of function
    dictionary references. An additonal oforce was required in the array
    processing loop. (lib/pdf_draw.ps [1.36]: 2001/10/16 22:20:31 dancoby)
    	- Applied two patches reported in
    http://www.ghostscript.com/pipermail/gs-code-review/2001-October/001255.html
    by Hideyuki Suzuki / hideyuki at sat dot t dot u-tokyo dot ac dot jp.
    pdf_font.ps: automatic substitution & transformation of CID-keyed fonts.

    lib/pdf_ops.ps [1.17]: 2001/10/19 16:42:47 masata-y)

## Interpreter

    Fixes problems:
    	- Adds a -dNOCCFONTS switch to disable use of compiled-in fonts.
    (lib/gs_ccfnt.ps [1.5], lib/gs_init.ps [1.39]: 2001/10/01 05:25:55 lpd)
    	- After removing a compiled font with undefinefont, loading the font
    or asking for its resourcestatus left extra information on the stack. Fixes
    SourceForge #458818. (lib/gs_res.ps [1.16]: 2001/10/01 05:56:58 lpd)
    	- Clean up PostScript files in examples directory to prevent
    spurious bug reports caused when running more than a sigle file or running
    chess.ps without cheq.ps in the current directory. Thanks to Russell Lang
    for cleanup on DSC comment and structure. (examples/alphabet.ps [1.2],

    gp_stdin.c to use fread/fwrite to be more portable. Flush redirected stdout
    correctly. Added casts to fix compiler warnings in dxmain.c. Corrected

## Streams

    Fixes problems:
    	- Updates icclib to version 2.0, and integrates icclib changes. In
    particular, icclib now accesses Ghostscript streams through the clean
    icmFile object interface, rather than previous hack. Removes remnants of
    previous hack, including gs_stdio.h header file and sread() and swrite()
    functions in stream.c. (stream.c [1.15]: 2001/10/19 21:52:50 raph)

## Library

    Fixes problems:
    	- Fixes nontermination of triangle subdivision in shading, as
    triggered by FTS 446-01.ps. The criterion for whether a triangle spans more
    than one pixel was too conservative, as it took the fill adjust into
    account. (gxshade4.c [1.6]: 2001/10/01 21:16:47 raph)
    	- Correct inverted Decode cases of ImageType 4 color range masks for

# Version 7.02 (2001-09-22)

This is a prerelease of Ghostscript, in preparation for a forthcoming fully tested, supported 7.0x release. We are skipping the 7.01 release number because that number is now associated with CVS versions.

Major changes include:

- Compile and portability fixes, including the dreaded time.h problem that affects up-to-date Linux builds.
- Big improvements in stdio, including a new -sstdout= redirect switch. In addition, reading from stdin uses nonblocking I/O, so the ugly -_ workaround is no longer necessary.
- Substantial pdfwrite improvements.
- 128-bit encrypted files are now supported.
- The usual bug fixes.

Release issues that will be fixed before next fully supported version:

- Update icclib to 2.0.
- Update hpijs and Omni glue to latest versions.
- Make sure all source files are referenced in Develop.htm.

The following SourceForge bug numbers are currently open: 215256, 219798, 222727, 224863, 226477, 405342, 406285, 406689, 406979, 407342, 411753, 413669, 414947, 414985, 415016, 415142, 415170, 415177, 415526, 416043, 416131, 416830, 418241, 418597, 421057, 422532, 423838, 426274, 427193, 427314, 427316, 427347, 428891, 428973, 430879, 431065, 432040, 432657, 433835, 434277, 434707, 435154, 436099, 436897, 437285, 438679, 438957, 441566, 442477, 443745, 444791, 446344, 446672, 446676, 446035, 447695, 448199, 450271, 450663, 451456, 452155, 452173, 453861, 453969, 457838, 458025, 458261, 458500, 458769, 458775, 458780, 458818, 459645, 459647, 459764, 460292, 462139, 462212, 462221, 462319, 462777, 463123, 463400.

## Procedures

    Fixes problems:
    	- Removing the dependence of graphic library on PS interpreter.
    Source Forge bug #415003. (lib.mak [1.48]: 2001/04/20 09:38:39 igorm)
    	- Undoes makefile breakage introduced in previous version (for VMS).
    (icclib.mak [1.3], lib.mak [1.50]: 2001/04/24 18:36:55 raph)
    	- !ifndef COMPILED_INITS instead of !ifndef COMPILE_INITS Discovered
    fixing bug #414985 from anonymous user (msvclib.mak [1.13]: 2001/04/28
    00:53:46 alexcher)
    	- Optimization for shading fill. The general path filling algorithm
    subdivides fill region with trapezoid or rectangle subregions and then
    paints each subregion with given color. If the color is shading, each
    subregion to be subdivided into areas of constant color. But with radial
    shading each area is a high order polygon, being subdivided into smaller
    subregions, so as total number of subregions grows huge. Faster processing
    is done here by changing the order of subdivision cycles : we first
    subdivide the shading into areas of constant color, then apply the general
    path filling algorithm (i.e. subdivide each area into trapezoids or
    rectangles), using the filling path as clip mask. Source Forge bug #414022.
    (lib.mak [1.51]: 2001/05/10 18:36:40 igorm)
    	- Adobe PhotoShop 5+ duotone code assumes that setcolor operator
    calls tint transform function if source colors don't make a subset of device
    colors. Bug #224056, Customer #150 (int.mak [1.47]: 2001/06/07 14:48:24
    alexcher)
    	- index.html and gs.css weren't being copied to the installed
    documentation directory. (unixinst.mak [1.19]: 2001/07/25 21:10:39 giles)
    	- define previously undefined make variables. DISPLAY_DEV in
    unix-gcc.mak. gdevdsp_h and gdevdsp2_h in int.mak. Add missing iref.h
    dependency for idisp. Bug #415006. (devs.mak [1.46], int.mak [1.48],
    unix-gcc.mak [1.22]: 2001/08/01 08:58:49 ghostgum)
    	- Link Linux shared object as position independent code, instead of
    just compiling the modules as position independent. Adds prefix to shared
    object recursive make to allow install to a temporary location while
    building a distribution. (unix-dll.mak [1.3]: 2001/08/01 09:42:01 ghostgum)
    	- allow any value of JVERSION in the platform-specific makefiles to
    reduce user confusion over minor version naming. We continue to support only
    libjpeg v6*. Sourceforge bugs #457617 and #457838, September 2001.
    (jpeg.mak [1.4]: 2001/09/05 21:46:35 giles)
    	- Fix for MS-Windows graphics library. Remove references to
    interpreter from gp_check_interrupts function in library. Make gslib.c
    access gs_stdin not stdin. Correct the build paths for graphics devices. Add
    missing graphics devices. (msvc32.mak [1.18], msvclib.mak [1.16],
    winlib.mak [1.11]: 2001/09/22 07:07:02 ghostgum)
    	- Prevent memory corruption when reading %statementedit. Allocate
    lineedit buffer in correct memory space. Line being assembled is stored in a
    PostScript string during callouts, so prevent zfilelineedit from reading
    more than max_string_size bytes. Allocate extra space for trailing new-line
    for statementedit, rather than fiddling the string length which broke when
    sreadline reallocated the string. (int.mak [1.50]: 2001/09/22 07:26:45
    ghostgum)
    	- pdfwrite failed to recognize several of the standard screen spot
    functions: Ellipse, Round, and Diamond weren't implemented, and several of
    the others didn't match the PostScript implementation because of
    float/double discrepancies. Also, pdfwrite wrote out halftone screens using
    the adjusted ("actual") frequency and angle values rather than the requested
    values. Fixes SourceForge #446676. (devs.mak [1.47]: 2001/09/22 16:27:04
    lpd)

    Increments version number after 7.00 release. Also fixes gs_init.ps to
    consistently print minor revision number as two digits. (version.mak [1.34]:

    Changes gp_open_scratch_file() to use mkstemp() rather than mktemp() on gcc
    builds, which avoids warnings. Adds CAPOPT variable to unix-gcc.mak to
    select which function is used, so that builds will still succeed on systems
    that don't have mkstemp(). (unix-gcc.mak [1.20]: 2001/05/07 19:05:46

    This file is a new utility intended for debug. It is not yet ready for prime
    time, but is available for whoever wants to fix it. The main problems are:
    1. It doesn't work for files that use chained filters such as [
    /ASCII85Decode /FlateDecode ] 2. The PDF files that are written are
    sometimes broken. GS gets an xref problem. This second problem may actually
    due to lib/pdfwrite.ps since even when no conversion is done, the file is
    bad. (toolbin/pdfinflt.ps [1.1]: 2001/05/31 04:54:51 rayjj)

    This revision allows the MSVC makefiles to work with spaces in the DEVSTUDIO

    To reduce redraw flicker, do not allow Windows to erase the background since
    we paint it ourselves. Paint areas outside the page with the window
    background colour or light grey. Save and restore window size using
    registry. Add "Paste" to system menu of text window. Make error message box
    a child of text window to avoid it appearing behind the text window. To
    allow user to read the error message, the text window is not automatically
    destroyed in the event of an error. The user must close text window using
    close button or system menu. If text window closed, return e_Fatal to poll
    function to provide a cleaner exit without a stack dump. (winint.mak [1.8]:

    The Unix shared object loader 'gsx' depends on Gtk+ which causes it to fail

## Utilities

    Fixes problems:
    	- null object was converted to -nostringval- Discovered during the
    work on pdfopt. (lib/pdfwrite.ps [1.4]: 2001/04/28 01:01:38 alexcher)
    	- On Windows GS enumerated "." and ".." as external resources and
    failed with /invalidresource trying to load them later. (gp_ntfs.c [1.5]:
    2001/05/04 20:27:40 alexcher)
    	- pass #xx escaped characters in names through and fix the escape
    logic to prevent a /typecheck in add. (lib/pdfwrite.ps [1.5]: 2001/05/31
    04:38:42 rayjj)
    	- Many scripts for invoking Ghostscript-based utilities didn't
    properly handle file names that included spaces. Unix and DOS/Windows/OS/2
    scripts required different fixes. (lib/dvipdf [1.2], lib/eps2eps [1.3],
    lib/eps2eps.bat [1.5], lib/gssetgs.bat [1.3], lib/pdf2dsc.bat [1.2],

    	- pdfopt gave an error if the input file had PageMode = /UseOutlines
    but lacked an Outlines tree. Fixes SourceForge bug #410371.
    (lib/pdfopt.ps [1.5]: 2001/07/01 07:16:28 lpd)
    	- The first pass of pdfopt always estimated the size of the primary
    hint stream as 0, which occasionally caused the second-pass fixup to fail.
    Fixes SourceForge bug #409887. (lib/pdfopt.ps [1.7]: 2001/07/01 07:23:36
    lpd)
    	- If the OpenAction of a document referred to a Page object, pdfopt
    would try to include the page in the "document-level objects" section of the
    output, causing a rangecheck error. Fixes SourceForge bug #437724. Also adds
    more tracing to pdfopt (with -dPDEBUG). (lib/pdfopt.ps [1.8]: 2001/07/02
    15:50:19 lpd)
    	- gp_open_scratch_file concatenated the temporary directory name
    with the prefix even if the prefix was an absolute path; also, it didn't
    check the length of the final file name, possibly leading to memory
    corruption. (gp_iwatc.c [1.6], gp_mswin.c [1.6], gp_os2.c [1.10],
    gp_vms.c [1.7]: 2001/07/15 13:57:50 lpd)
    	- glyphshow procedure in ps2ascii lacks a pop in the for loop. Patch
    from Leon Bottou. Source Forge bug #443361. (lib/ps2ascii.ps [1.3]:
    2001/07/22 20:43:32 igorm)
    	- pdfopt was broken because SAFER prevented it from opening its
    output and temporary files, and from deleting its temporary files. Note:
    this fix requires the .tempfile operator added in src/zfile.c [1.9].
    (lib/pdfopt [1.4], lib/pdfopt.bat [1.4], lib/pdfopt.ps [1.9]: 2001/07/23
    06:57:27 lpd)
    	- Running font2c on any of the 35 standard fonts caused an
    invalidaccess error if gs was built with compiled fonts (ccfonts.dev
    "feature"). Fixes SourceForge #458816. (lib/font2c.ps [1.3]: 2001/09/13
    23:16:29 lpd)
    	- Fix for MS-Windows graphics library. Remove references to
    interpreter from gp_check_interrupts function in library. Make gslib.c
    access gs_stdin not stdin. Correct the build paths for graphics devices. Add
    missing graphics devices. (gp_mslib.c [1.3], gp_mspol.c [1.1],

    2001/07/30 07:16:32 lpd)

    The Unix shared object loader 'gsx' depends on Gtk+ which causes it to fail
    in an environment where X11 and Gtk+ are not available. Add a console only
    loader 'gsc' which does not depend on X11 or Gtk+. This does not support the
    'display' device. Fixes sourceforge bug #450933. (dxmainc.c [1.1]:

## PDF writer

    Fixes problems:
    	- Empty pages included a Contents entry whose value was an empty
    array: the spec allows this, and AR3 and 4 accept it, but AR5 rejects it.
    (gdevpdf.c [1.34]: 2001/06/29 06:52:13 lpd)
    	- When tiling with a bitmap, the /Type entry in the Pattern resource
    was written twice. (Minor file size problem only, not a functional problem.)
    (gdevpdfb.c [1.5]: 2001/06/29 17:04:17 lpd)
    	- Some poorly designed PDF tools couldn't handle the fact that the
    Contents stream of each page was not surrounded by q/Q. (The PDF spec does
    not require this.) Fixes SourceForge bug #231390. (gdevpdfu.c [1.16]:
    2001/07/02 18:07:55 lpd)
    	- pdfwrite didn't set returned.current_char, so the "current
    character" for kshow was 0 or a random value. Fixes SourceForge bug #420933.
    (gdevpdfs.c [1.5]: 2001/07/02 19:09:23 lpd)
    	- When producing text in a Type 3 (bitmap) font and using TL and '
    for Y positioning, emitting a horizontal space character reset
    text.use_leading, causing the line to be positioned incorrectly. Fixes
    SourceForge bug #427159. (gdevpdft.c [1.33]: 2001/07/04 16:47:33 uid22160)
    	- When producing text using a Type 3 (bitmap) font, the TL command
    was used (incorrectly) when the new text position was directly below the
    current text position, not (correctly) when the new text position was
    directly below the beginning of the current text line. Fixes SourceForge bug
    #228180. (gdevpdft.c [1.34]: 2001/07/04 18:06:39 uid22160)
    	- Scaled fonts with PaintType = 2 (stroked) were painted with
    incorrect stroked width. (gdevpdfs.c [1.6]: 2001/07/04 21:57:02 uid22160)
    	- pdfwrite generated masked images, a PDF 1.3 feature, even when
    CompatibilityLevel < 1.3. Fixes item (2) of SourceForge bug #414104.
    (gdevpdfj.c [1.7], gdevpdfv.c [1.6]: 2001/07/07 19:15:51 lpd)
    	- pdfwrite could write out a Pattern image too large for Acrobat
    Reader to handle, which would then never be referenced. Fixes item (4) of
    SourceForge bug #414104. (gdevpdfv.c [1.7]: 2001/07/07 19:41:12 lpd)
    	- MSVC requires that a label not be the last thing in a block.
    (gdevpdfv.c [1.9]: 2001/07/08 13:46:25 lpd)
    	- The algorithm for scaling down user coordinates to fall within
    Acrobat Reader's limitations didn't work properly for stroked paths with
    anisotropic CTMs, possibly producing large coordinates that led Acrobat (but
    not Ghostscript) to display the resulting file incorrectly. Fixes
    SourceForge bug #440476. (gdevpdfd.c [1.15], gdevpdfp.c [1.18],
    gdevpdfx.h [1.30]: 2001/07/12 03:28:02 lpd)
    	- pdfwrite didn't write transfer functions in the output for images,
    and allowed lossy compressions on images even in the presence of peculiar
    transfer functions (such as functions simulating indexed color spaces). This
    fix writes transfer functions for images, prevents lossy compression if the
    transfer function is not the identity, and undoes the hack that was
    implemented earlier to work around this problem. Fixes SourceForge bug

    gdevpdfx.h [1.31]: 2001/07/12 05:47:07 lpd)
    	- When writing text, the leading offset was sometimes ignored if
    blank lines were followed by a non-blank line. Fixes SourceForge bug
    #440490. (gdevpdft.c [1.35]: 2001/07/12 19:45:53 lpd)
    	- If ConvertCMYKImagesToRGB was true, pdfwrite produced images with
    the correct RGB data but with the color space still set to DeviceCMYK. (Fix
    originally from Helge Blischke.) (gdevpdfi.c [1.23]: 2001/07/24 04:47:37
    lpd)
    	- The calculation of a scaling value for stroked paths was
    incorrect, causing Inf and NaN values to be written in the PDF file. Fixes
    SourceForge #444682. Bug was introduced by the fix for #440476.
    (gdevpdfd.c [1.16]: 2001/07/27 22:28:31 lpd)
    	- Some error codes were ignored, masking errors in writing embedded
    fonts. (gdevpdfe.c [1.10]: 2001/07/31 06:32:42 lpd)
    	- ICCBased color spaces were copied to the output even if the output
    level was 1.2 (ICCBased color spaces were introduced in PDF 1.3).
    (gdevpdfc.c [1.16]: 2001/08/02 20:29:07 lpd)
    	- If an image used a color space that couldn't be represented in
    PDF, an invalid file was produced, rather than falling back to the default
    representation as tiny rectangles. (bug introduced by H. Blischke's color
    space fix) (gdevpdfi.c [1.24]: 2001/08/03 16:12:16 lpd)
    	- Type 1 fonts that did not use the standard 1000-unit cell, such as
    some fonts in PostScript files produced by Windows NT 4.0, were written with
    an incorrect FontMatrix. (The output was visually correct, because the font
    size was scaled to compensate.) Fixes SourceForge #439474.

    	- If the base 14 fonts were being embedded, they would often be
    embedded multiple times. Partially fixes SourceForge #438957.
    (gdevpdff.c [1.20]: 2001/08/17 21:27:21 lpd)
    	- The descriptors for embedded fonts were recomputed unnecessarily.

    2001/08/29 19:03:59 lpd)
    	- Uncolored Patterns with all bits set (equivalent to a solid color)
    crashed pdfwrite. Fixes SourceForge #461330. (gdevpdfv.c [1.10]: 2001/09/15
    06:12:29 lpd)
    	- pdfwrite failed to recognize several of the standard screen spot
    functions: Ellipse, Round, and Diamond weren't implemented, and several of
    the others didn't match the PostScript implementation because of
    float/double discrepancies. Also, pdfwrite wrote out halftone screens using
    the adjusted ("actual") frequency and angle values rather than the requested
    values. Fixes SourceForge #446676. (gdevpdfg.c [1.14]: 2001/09/22 16:27:04

## PDF Interpreter

    Fixes problems:
    	- 5-element DeviceN array (with attributes) messed up the operand
    stack and failed. The attributes is an informational entry that can be
    safely ignored. Bug #419509, Customer #150. (lib/pdf_draw.ps [1.30]:
    2001/04/28 01:45:25 alexcher)
    	- PDF files containing strings with codes that map to glyph names
    that are not part of the font would error with undefined in --get--.
    Substitute the .notdef glyph as Adobe Acrobat Reader apparently does.
    (lib/pdf_font.ps [1.19]: 2001/05/12 00:11:42 rayjj)
    	- .resolvefn4 used stream length as the length of the decompressed
    data, truncated the PostScript procedure and caused syntax error in the
    token operator because of the unmatched brackets. Reading directly from the
    stream fixes the problem. Bugs #425919 (lib/pdf_draw.ps [1.31]: 2001/05/24
    16:48:59 alexcher)
    	- The March 1999 PDF 1.3 version of the specification had a change
    to make the /FormType key and /Matrix key optional in a Form. While we had
    already handled missing /Matrix key, the missing /FormType key was not
    accounted for in all cases. Move this to the common DoForm code. Fix for
    SourceForge bug #430556, Artifex customer #671. (lib/pdf_draw.ps [1.32]:
    2001/06/13 05:30:29 rayjj)
    	- Wrong entry name (BaseFont instead CIDFontName) was used while
    resolving font resource to CIDFontType2 in PDF interpreter. Source Forge bug
    #436892 (lib/pdf_font.ps [1.20]: 2001/07/09 19:27:37 igorm)
    	- Workaround a SEGV caused by GC interaction with stderr file.
    Needed to complete the fix for #430556, but the stderr bug remains open as
    442477. (lib/pdf_main.ps [1.34]: 2001/07/18 20:42:48 rayjj)
    	- Detect and load embedded Type1 fonts that are in PFB format (have
    the 6 byte PFB header before each segment). Also ignore /Length values in
    the streamdict keys that don't match the PFB segnment lengths. Issue warning
    messages to stderr for all of these spec violations. SourceForge bug #430556
    for Artifex customer #671. VS:
    ----------------------------------------------------------------------
    (lib/pdf_font.ps [1.21]: 2001/07/18 20:45:35 rayjj)
    	- This problem was a rangecheck error being reported in
    .setindexedspace when the base colorspace was DeviceN. The cause was an
    error in determining the number of components in the DeviceN space. This is
    the second of two fixes for SF bugs 427165 (customer #1110) and 438682.
    (lib/pdf_draw.ps [1.34]: 2001/08/21 23:54:30 dancoby)

    Improvement: Prevents PDF files with more than 65534 page from failing due
    to the dict size limit. The caches never hit on pages past 65534. Problem
    was reported by a potential Artifex customer re their customer's files.
    (lib/pdf_main.ps [1.33]: 2001/05/12 17:15:41 rayjj)

    This is the fix for [ #427354 ] PDF checkboxes problem. The PDF annotation
    handler was not correctly handling cases in which there was no appearance in
    the appearance dictionary AP for the current appearance state AS. It should
    not display anything in this case. (lib/pdf_draw.ps [1.33]: 2001/06/14
    22:25:36 dancoby)

    Updates pdf_sec.ps to use the new PDF 1.4 algorithms and 128 bit keylengths.
    Rewritten to use C implementations of Arcfour (RC4 compatible cipher) and
    MD5. Also fixes bug in processing of zero-length streams.

## Interpreter

    Fixes problems:
    	- GS didn't exit to shell when it was used with '--' option. The bug
    was introduced in revision 1.7 when many references to exit() were replaced
    with returns. Bug #416498 by Paul Vojta (imainarg.c [1.11]: 2001/04/19
    23:39:39 ghostgum)
    	- Removing the dependence of graphic library on PS interpreter.
    Source Forge bug #415003. (zcssepr.c [1.8]: 2001/04/20 09:38:39 igorm)
    	- Auto-rotation is enabled for non-null orientations. Auto rotation
    now always rotates the image +90 degrees relative to the orientation. Bug
    #416830 Customer #430 (zmedia2.c [1.3]: 2001/04/26 17:57:41 alexcher)
    	- EPS files without a showpage could not be viewed if given as a
    command line arg. Extra call to display_set_callback erased the page before
    going to the GS> prompt the first time. Only do display_set_callback as
    part of init_2. (imain.c [1.13]: 2001/05/04 20:35:33 rayjj)
    	- in global mode pdfmark with composite objects causes invalidaccess
    because the objects are copied to local memory but the array is copied to
    current memory. Now the array is copied to local memory too. Fix from Helge
    Blischke with changes. (lib/gs_pdfwr.ps [1.11]: 2001/05/04 20:59:33
    alexcher)
    	- This IdiomSet replaces 3 procedures generated by Win2K driver in
    level 1 mode for RGB source image and DeviceRGB, DeviceCMYK, and DeviceGray
    color models. Original implementation uses transfer functions to simulate
    the indexed color space. Currently, GS always ignore transfer functions. The
    replacement procedure uses indexed color space directly. This Idiom should
    really be in a file in the IdiomSet directory of the Resource path, but we
    put it here until GS has a way to handle distribution and installation of
    Resources. Customer #670, Bug #420257 (lib/gs_ll3.ps [1.9]: 2001/05/08
    19:42:13 alexcher)
    	- Add all page sizes supported in statusdict to the .pagetypenames
    array so that these page sizes can be selected from the command line using
    -sPAPERSIZE=... parameter. Also implement the STRICT that limits the
    available known paper sizes to those Adobe had defined prior to Level 2 when
    'setpagedevice' replaced this mess. SourceForge bug #427898
    (lib/gs_statd.ps [1.5]: 2001/05/30 21:14:35 rayjj)
    	- Fix for [ #419211 ] .parse_dsc_comments not robust. This change
    modifies the DSC parser so that errors in DSC comments do not abort the file
    processing. (zdscpars.c [1.11]: 2001/06/06 08:11:20 dancoby)
    	- Adobe PhotoShop 5+ duotone code assumes that setcolor operator
    calls tint transform function if source colors don't make a subset of device
    colors. Bug #224056, Customer #150 (zcolor2.c [1.4]: 2001/06/07 14:48:24
    alexcher)
    	- When finding a %%Page line in the trailer due to incorrect DSC
    comments, the DSC parser now returns CDSC_PAGE only if the parser treats it
    as a valid page. Partial fix for SourceForge bug #435157. (dscparse.c [1.6]:
    2001/06/23 10:21:24 ghostgum)
    	- Fix for [ #435157 ] segmentation fault in dsc_page. Add test for
    valid page data before using. (zdscpars.c [1.12]: 2001/06/27 00:25:08
    dancoby)
    	- Implementing CIDFont.CMap construction with period character (see
    Ken Lunde, "CJKV Information Processing," O'RELILLY. 1999. p284) for any
    compatible pair of CIDFont & CMap. This feature complies with Adobe
    CPSI. Thanks to Masatake Yamato for discovering this feature.
    (lib/gs_cidcm.ps [1.5]: 2001/07/01 08:55:34 igorm)
    	- Reading a TrueType font with an empty table could cause a
    rangecheck error. (lib/gs_ttf.ps [1.9]: 2001/07/08 15:24:11 lpd)
    	- pdfwrite didn't write transfer functions in the output for images,
    and allowed lossy compressions on images even in the presence of peculiar
    transfer functions (such as functions simulating indexed color spaces). This
    fix writes transfer functions for images, prevents lossy compression if the
    transfer function is not the identity, and undoes the hack that was
    implemented earlier to work around this problem. Fixes SourceForge bug
    #420257. (lib/gs_ll3.ps [1.10]: 2001/07/12 05:47:07 lpd)
    	- zfilelineedit sometimes reallocates (resizes) buffer string
    without updating reference to it from o-stack, so as console input after
    callout reads undefined data. Fixed with copying new reference to o-stack
    whenever it changes. Source Forge bug #437808 (ziodev.c [1.5]: 2001/07/16
    08:38:14 igorm)
    	- If a 'restore' had to restore page device parameters, it did so
    before rather than after restoring the state of VM, possibly creating
    dangling references. Fixes SourceForge #230694, #414588, #444565.
    (lib/gs_setpd.ps [1.8], zdevice2.c [1.4]: 2001/07/30 07:11:38 lpd)
    	- Ignore white space between %%DocumentData: and argument. Fix: Set
    dsc->preview correctly to DOS EPS if both DOS EPS and EPSI previews are
    present. Update to latest dscparse.c/h used in GSview. Change dscparse to
    mark internal functions "dsc_private" not "private", so it can be compiled
    as C++ (needed by GSview, not Ghostscript). (dscparse.c [1.7],
    dscparse.h [1.6]: 2001/08/01 09:03:40 ghostgum)
    	- Fixing wrong binding of .getmetrics32 with -dNOBIND.
    (lib/gs_typ32.ps [1.3]: 2001/08/06 10:19:42 igorm)
    	- Old hack about underline parameters in gs_type1.ps now conflicts
    with QuarkXPress_4.1 3.0 0 procset. Disabling it for fonts, which have
    degenerate FontBBox. Source Forge bug #441870. (lib/gs_type1.ps [1.5]:
    2001/08/06 16:47:43 igorm)
    	- The problem was a rangecheck error being reported in
    .setdevicenspace with PDF files. The cause of the problem was not allowing
    multiple copies of the name /None in DeviceN colorant specification. This is
    the first of two fixes for SF bugs 427165 (customer #1110) and 438682.
    (zcsdevn.c [1.4]: 2001/08/21 23:52:36 dancoby)
    	- Work around a bug in the Adobe AGM_Core that results in areas
    painted by the tint transform of a spot color being overpainted with white.
    The symptom is missing graphics (lines, fills or text). SourceForge bug

    object. (lib/gs_btokn.ps [1.4]: 2001/09/04 22:59:52 masata-y)
    	- If MaxLocalVM user parameter is set, perform garbage collection
    before checking for potential VMerror. Without this fix, VMerror would be
    issued even if a garbage collection would have freed enough memory to stay
    below the MaxLocalVM limit. (ireclaim.c [1.3]: 2001/09/05 17:50:36 rayjj)
    	- Prevent memory corruption when reading %statementedit. Allocate
    lineedit buffer in correct memory space. Line being assembled is stored in a
    PostScript string during callouts, so prevent zfilelineedit from reading
    more than max_string_size bytes. Allocate extra space for trailing new-line
    for statementedit, rather than fiddling the string length which broke when
    sreadline reallocated the string. (zfile.c [1.11], ziodev.c [1.6]:
    2001/09/22 07:26:46 ghostgum)

    If an ICC color space failed to load, Acrobat Reader uses the alternate

    Patch from Mr. Toshiya Suzuki : Implementing multi-dimensional CID ranges,

    consumes undefined byte sequence (which cannot be mapped to some glyphs), GS
    aborts. (2) when selected CID font lacks the glyph for requested CID, GS
    aborts. (3) "notdefrange" defines SINGLE CID for undefined byte sequences in

    calculate MULTIPLE CID. (4) "cidrange" operators accept only full range

    Change to debug output so that when the ptr is totally bogus, some useful
    output will be generated before otype->ssize is dereferenced (which can
    cause a memory access crash such as SEGV). No effect on non-debug code.

    When using gswin32 (GUI version) and an error occurs or -? is used, do not
    display an error message box. Add a message to the text window "Close this
    window with the close button on the title bar or the system menu". Flash the

## Streams

    Fixes problems:
    	- When input stream of an input filter reports EOF, old code reports
    EOF for the filter. But if output buffer for the filter is not empty, EOF
    status to be delayed until it empties. Source Forge bug #417127.
    (stream.c [1.12]: 2001/05/05 10:12:23 igorm)
    	- Non-stable memory was used for internal zlib data, causing
    inconsistent heap state after 'restore' while zlib is active, and subsequent
    crash. Source Forge bug #431057 (szlibc.c [1.3]: 2001/07/16 08:29:46 igorm)
    	- Fixes numerous bugs in setting of DCT compression parameters.
    Manual setting of parameters such as QFactor should now work. Also
    ColorTransform now defaults to YCC instead of RGB color space so the default
    quality and compression ratio should improve. Thanks to Dave Slattengren for
    the initial version of this fix. (sdcparam.c [1.3], sdcte.c [1.4],
    sdeparam.c [1.4]: 2001/09/01 23:54:57 raph)
    	- fixes bounds overstepping in arcfour filter in the case where
    write buffer space is smaller than read buffer space. (sarc4.c [1.5]:

    and sdcte.c) (sdct.h [1.4]: 2001/06/08 07:08:44 rayjj)

    Adds a comment describing the function and return value of sreadbuf.
    (stream.c [1.14]: 2001/06/17 04:28:10 lpd)

    Adds extern_inline for including inline procedures in header files.
    (stdpre.h [1.4]: 2001/06/17 05:09:07 lpd)

    These changes were originally put into the GS_6_5 branch on 2001/03/13. They
    are needed for using the current version of teh graphics library with the
    PCL6 code. Short description of changes: stat_.h: Added definition of
    stat_is_dir for use with MSVC. Not used in Ghostscript. gsptype1.c: Changes
    in image_PaintProc. This routine is used in gs_makepixmappattern.
    gs_makepixmappattern is only used in test8 (in gslib.c - a test module) and
    gs_makebitmappattern_xform. gs_makebitmappatern_xform is not used in
    Ghostscript. It is used in pcl6. (stat_.h [1.6]: 2001/08/07 22:13:29
    dancoby)

    Makes the spprint* procedures use sputc rather than sputs for printing
    converted values. Speeds up one set of customer ps2pdf conversions by 2.5%.
    (spprint.c [1.4]: 2001/08/25 06:59:04 lpd)

## Library

    Fixes problems:
    	- When copying a device, copy the static procs if needed before
    calling finish_copydevice, so that the correct finish_copydevice is used.
    (gsdevice.c [1.9]: 2001/04/12 08:45:02 ghostgum)
    	- Removing the dependence of graphic library on PS interpreter.
    Source Forge bug #415003. (gscsepr.c [1.10], gscspace.h [1.7]: 2001/04/20
    09:38:38 igorm)
    	- Removing the dependence of graphic library on PS interpreter.
    Source Forge bug #415003. (gscsepr.c [1.11]: 2001/04/20 10:07:48 igorm)
    	- Optimization for shading fill. The general path filling algorithm
    subdivides fill region with trapezoid or rectangle subregions and then
    paints each subregion with given color. If the color is shading, each
    subregion to be subdivided into areas of constant color. But with radial
    shading each area is a high order polygon, being subdivided into smaller
    subregions, so as total number of subregions grows huge. Faster processing
    is done here by changing the order of subdivision cycles : we first
    subdivide the shading into areas of constant color, then apply the general
    path filling algorithm (i.e. subdivide each area into trapezoids or
    rectangles), using the filling path as clip mask. Source Forge bug #414022.

    fail in unpredictable ways. (gsdevice.c [1.10]: 2001/05/12 00:08:36 rayjj)
    	- dev_color_eq used wrong number of components for halftones. Source
    Forge bug #422534. (gsht1.c [1.3], gxcht.c [1.3]: 2001/05/12 14:51:52 igorm)
    	- Current code for /All separations marks all planes in the
    alternate color space, not the destination color space. This is wrong, but
    gx_concretize_Separation() doesn't have access to the destination device
    color space. This fix makes tint value 1 print as black in any alternate
    color space. It printed as white in DeviceCMYK before. Bug #423838
    (gscsepr.c [1.12]: 2001/05/25 13:54:01 alexcher)
    	- Prevent SEGV caused by freeing memory not owned. Variable 'code'
    was overwritten, losing the get_outline return code that was needed for the
    decision to free the glyph_string.data. Problem detected with PCL. Bug was
    introduced in rev 1.10. (gstype42.c [1.12]: 2001/05/31 04:34:23 rayjj)
    	- Include <time.h> as required by Debian systems with glibc
    2.2. Fixes SourceForge bugs 413747, 417180, 417181, 417182. (time_.h [1.3]:
    2001/06/07 21:04:52 raph)
    	- FunctionType 4 functions that contained conditionals (if/ifelse)
    would report the length of their symbolic definition incorrectly;
    FunctionType 4 functions that had to return their symbolic definition in
    pieces would loop forever. Fixes SourceForge bug #427191. (gsfunc4.c [1.6]:
    2001/07/04 01:23:46 lpd)
    	- Changes clip logic in gx_image_cached_char() to affect the imaging
    device, so that clipping is reliably effective. Fixes SF bug #433821 (and
    probably others). (gxccache.c [1.5]: 2001/07/05 20:36:55 raph)
    	- Removes duplicate rc_decrement_only() in
    pdf14_begin_typed_image(), so that the marking device is now deallocated
    once. Fixes SourceForge bug #434705. (gdevp14.c [1.3]: 2001/07/05 23:21:00
    raph)
    	- Prevent non-persistent name_arrays of size==0 from causing a
    VMerror if alloc of size 0 returns a NULL. Detected with
    SeparationColorNames from the PCL code. (gscparam.c [1.7]: 2001/07/06
    17:02:25 rayjj)
    	- If the FontMatrix of a CFF CIDFont was the default [0.001 0 0
    0.001 0 0], it was not written, causing the FontMatrices of the subfonts to
    be scaled by 1000. (The Adobe documentation isn't at all clear about this.)
    Fixes SourceForge bug #428595. (gdevpsf2.c [1.14]: 2001/07/07 06:28:08 lpd)
    	- Before processing an image that uses the current color, call
    gs_state_color_load to ensure that if the current color is a pattern, the
    pattern is loaded. (This parallels existing code used for filling paths and
    processing text.) This prevents a SEGV caused when pdfwrite dereferenced a 0
    pointer to pdc->colors.pattern.p_tile. Fixes SourceForge bug #422089 for
    Artifex Customer #1110. (gsimage.c [1.4]: 2001/07/10 22:04:20 lpd)
    	- The algorithm for scaling down user coordinates to fall within
    Acrobat Reader's limitations didn't work properly for stroked paths with
    anisotropic CTMs, possibly producing large coordinates that led Acrobat (but
    not Ghostscript) to display the resulting file incorrectly. Fixes
    SourceForge bug #440476. (gdevvec.c [1.12], gdevvec.h [1.7]: 2001/07/12
    03:28:02 lpd)
    	- -sOutputFile=%stdout handling was broken by rev. 1.4 is fixed by
    giving priority to iodevices when there is a leading %, but if the iodevice
    is not recognized, attempting to parse as a format. Fix for SourceForge bugs

    14:10:55 rayjj)
    	- gp_open_scratch_file concatenated the temporary directory name
    with the prefix even if the prefix was an absolute path; also, it didn't
    check the length of the final file name, possibly leading to memory
    corruption. (gp_unifs.c [1.6]: 2001/07/15 13:57:50 lpd)
    	- An incorrect optimization in the conversion of Type 1 to Type 2
    CharStrings could cause character shapes to be mangled. This probably only
    affected embedded fonts in PDF output. Fixes SourceForge #444374.
    (gdevpsfx.c [1.9]: 2001/07/26 03:04:51 lpd)
    	- Acrobat Reader would not accept embedded TrueType fonts with a
    zero-length glyf table. Fixes SourceForge #429156. (gdevpsft.c [1.8]:
    2001/07/30 07:03:18 lpd)
    	- An embedded CFF font could not be larger than 64K. Fixes
    SourceForge #445400. (gdevpsf2.c [1.15]: 2001/07/31 06:39:06 lpd)
    	- For CIEBasedDEF(G) color spaces the interpolated values from the
    Table need to be scaled to the range given by RangeABC. Fixes SourceForge
    bug #440278 reported by Artifex customer #10. (gsciemap.c [1.6]: 2001/08/03
    15:26:35 rayjj)
    	- Correct a problem with white lines appearing in an image at or
    near band boundaries. Problem caused by different handling for the last
    image pixel at a band boundary versus the remaining pixels. Replaced it with
    uniform handling. Fixes SourceForge bug #436899 reported by Artifex customer
    #150. Also included are three lines of source code clean up in the same
    section. (gxicolor.c [1.3]: 2001/08/06 21:22:31 dancoby)
    	- Writing a Type 2 font subset with undefined glyphs in the Encoding
    produced invalid output. Fixes SourceForge #451399. (gdevpsf.h [1.10],
    gdevpsfu.c [1.7]: 2001/08/16 13:36:37 lpd)
    	- The problem was a rangecheck error being reported in
    .setdevicenspace with PDF files. The cause of the problem was not allowing
    multiple copies of the name /None in DeviceN colorant specification. This is
    the first of two fixes for SF bugs 427165 (customer #1110) and 438682.
    (gscdevn.c [1.6], gscspace.h [1.8]: 2001/08/21 23:52:36 dancoby)
    	- Most of the Type 1 hinting code was executed even when hinting was
    disabled. Part 2 of a two-part fix for SourceForge #451456.
    (gxhint3.c [1.3]: 2001/08/29 19:04:55 lpd)
    	- Quark Xpress turns off garbage collection with -2 vmreclaim when
    embedding EPS files which can lead to rampant allocation that is only
    reclaimed when GC is reenabled. When the GC is disabled, reduce the
    threshold from 2 Gb to 8 Mb. Fixes SourceForge bugs: 444370 and 438676.

    If an ICC color space failed to load, Acrobat Reader uses the alternate

    Patch from Mr. Toshiya Suzuki : Implementing multi-dimensional CID ranges,

    consumes undefined byte sequence (which cannot be mapped to some glyphs), GS
    aborts. (2) when selected CID font lacks the glyph for requested CID, GS
    aborts. (3) "notdefrange" defines SINGLE CID for undefined byte sequences in
    specified range, but current GS implementation take it as an offset to
    calculate MULTIPLE CID. (4) "cidrange" operators accept only full range

    This was suggested by Graeme Gill. (icclib/icc.c [1.5]: 2001/06/06 08:14:14

## Procedures

    Completes the change of default X directories to /usr/X11R6. Last commit on
    this was inadvertently incomplete. (unix-gcc.mak [1.19],
    unixansi.mak [1.14]: 2001/04/07 23:34:40 raph)

    Updates version number and date in preparation for 7.00 release.
    (version.mak [1.33]: 2001/04/09 06:20:03 raph)

## Utilities

    Fixes problems:
    	- Correct the Unix executable handing of the display device formats
    of 8bit and 24bit per pixel RGB. (dxmain.c [1.3]: 2001/04/08 08:40:29
    ghostgum)
    	- Ghostscript should return to the caller, not exit. Remove exit()
    from gp_do_exit() for all platforms except VMS. (gp_dvx.c [1.4],
    gp_iwatc.c [1.5], gp_os9.c [1.4], gp_unix.c [1.5]: 2001/04/08 08:43:24
    ghostgum)

## PDF writer

    Fixes problems:
    	- AR4 doesn't like fonts with empty FontBBox which happens when the
    font contains only space characters. Small BBox causes AR 4 to display a
    hairline. So we use the full BBox. (gdevpdfw.c [1.11]: 2001/04/08 14:12:56
    alexcher)

## Interpreter

    Fixes problems:
    	- Ghostscript should return to the caller, not exit. Remove exit()
    from gp_do_exit() for all platforms except VMS. (gs.c [1.6]: 2001/04/08
    08:43:24 ghostgum)
    	- Need a cast to (gs_memory_t *) to prevent errors on some
    compliers. Change provided by Nelson H. F. Beebe. (zfdctd.c [1.6]:
    2001/04/09 05:15:57 rayjj)
    	- Setting an ICC color space now invalidates the joint cache, so
    that TransformPQR gets computed. The profile is explicitly loaded so that
    the TransformPQR procedures have access to the white point. Also, the
    photometric interpretation of the hack for /All separation color spaces is
    reversed. Fixes Fixed_Original.pdf from Michael Jahn and Adobe tech note
    5002_EPSF_Spec.pdf. (zicc.c [1.2]: 2001/04/09 06:09:58 raph)

    Updates version number and date in preparation for 7.00 release.
    (lib/gs_init.ps [1.34]: 2001/04/09 06:20:03 raph)

## Library

    Fixes problems:
    	- Setting an ICC color space now invalidates the joint cache, so
    that TransformPQR gets computed. The profile is explicitly loaded so that
    the TransformPQR procedures have access to the white point. Also, the
    photometric interpretation of the hack for /All separation color spaces is
    reversed. Fixes Fixed_Original.pdf from Michael Jahn and Adobe tech note
    5002_EPSF_Spec.pdf. (gscsepr.c [1.9], gsicc.c [1.2], gsicc.h [1.2]:
