2013-03-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - version.sh, www/index.rst: Prepare for 1.3.18 release.

2013-03-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c (DisplayImageCommand): display is supposed to respond to +/-usePixmap, but was not. It was responding to +/-use_pixmap. Now it responds to both.

2013-03-03 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>

> - doc/GraphicsMagick.imdoc: Relocated some <im> .. </im> tags, to include several paragraphs that were omitted from the GraphicsMagick man page (Environment, Configuration Files, and Copyright).
> - doc/imdoc2man: the </pre> tag was being deleted instead of replaced with nothing, which caused the first line of the subsequent material to be joined to the last line of the <pre> block.

2013-03-02 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>

> - coders/png.c (ReadOnePNGImage): Avoid a libpng16 warning about storing unknown chunks.

2013-02-25 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>

> - coders/png.c (WriteOnePNGImage): Call png_set_bKGD(), etc., after png_set_IHDR() because they depend on members of info_ptr which are set by png_set_IHDR().

2013-02-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/resource.c (InitializeMagickResources): Enable the dynamic adjustment of OpenMP threads if there is more than one thread available.

2013-02-18 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>

> - configure.ac and configure: Check for libpng17 and libpng16.

2013-02-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - www/programming.rst: Add mention of Clement Farabet's Lua scripting language wrapper for GraphicsMagick.

2013-02-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/pixel_cache.c (GetCacheNexus): Re-write function so it has a single point of return. (AcquireCacheNexus): Reduce the number of return points. (SetCacheNexus): Re-write function so it has a single point of return.

2013-02-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - NEWS.txt: Update with latest news.
> - magick/export.c (ExportAlphaQuantumType): Fix export of alpha for RGBA image and depth 8. Due to typo, was exporting 16-bits rather than 8, causing output corruption or crashes. Resolves issue reported in SourceForge GraphicsMagick forum under title "CMYK per-channel byte order TIFF crashes gm".

2013-02-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/studio.h (MagickIsBlank): Add macro to substitute for ISO C99 isblank() which is not globally available. Update 'gm batch' code which had substituted isspace() for isblank() to use it.

2013-01-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c (BatchCommand): Flush stdout at key points in order to ensure that user sees text when it is produced.

2013-01-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/random.c (InitializeMagickRandomGenerator): Use MagickTsdKeyCreate2() in order to avoid a small memory leak.
> - magick/tsd.c (MagickTsdKeyCreate2): New private function to support allocating a thread-specific data key with a specified destructor function. For single-threaded build, MagickTsdKey_t is now type void* and there is provision to support the destructor function.

2013-01-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/command.c (BatchCommand): New 'gm batch' command to accept one or more GraphicsMagick commands from a specified text file, standard input, or CLI. Feature is implemented by Kenneth Xu. Submitted via SourceForge Patch #3602331 "Add interactive or batch mode support to 1.3.17".

2013-01-27 Glenn Randers-Pehrson <glennrp@simple.dallas.tx.us>

> - coders/png.c (WriteOnePNGImage): Added PNG48 and PNG64 support. Added PNG00 support (png encoder that inherits its color-type and bit-depth from the input, if the input was a PNG datastream).

2013-01-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - coders/png.c (WriteOnePNGImage): PNG8 support was using image->colors to decide if the input image is PseudoClass. This is totally bogus. Use image->storage_class to determine if image is PseudoClass and quantize image colors if it is not.
> - magick/delegate.c (InvokePostscriptDelegate): Only invoke MagickSpawnVP() if Ghostscript filename argument is non-empty. This argument may be empty if Ghostscript is not found on a Windows system. Report a "Failed to find Ghostscript" error if the Ghostscript command name is empty. Resolves SourceForge issue #3601816 "Win64 build crashes trying to convert PDF to any other format".
> - magick/utility.c (MagickSpawnVP): Verify that file argument is non-NULL and not empty.

2013-01-15 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - VisualMagick/tiff/LIBRARY.txt: Fix pre-processor definitions for libtiff so that they use multiple statements rather than one long statement. Resolves SourceForge issue 3601001 "libtiff won't compile with ICL".

2013-01-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/memory.h (MagickAllocateAlignedArray): New macro to wrap use of MagickMallocAlignedArray().
> - magick/memory.c (MagickMallocAlignedArray): New private function to support safe allocation of an array in memory with a specified alignment. Allocation may only be freed using MagickFreeAligned() and the allocation may not be reallocated.

2013-01-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - magick/{animate.c,display.c,utility.c}: Only invoke chdir() if path is not an empty string. Previously sometimes chdir() was passed an empty string (because chdir() was not needed) and this was ok because we ignored the error status. Now that we check the chdir() error status, some X11 GUI functions (e.g. save file to current directory) encounter annoying issues.
> - magick/shear.c (IntegralRotateImage): Limit integral rotate to two threads.
> - coders/pnm.c (ReadPNMImage): Limit PNM reader to two threads.

2013-01-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

> - configure.ac (MAGICK_FEATURES): MinGW static build does not build modules so MODULES feature should not be listed as supported. Resolves MinGW test failures.
> - coders/dpx.c (OrientationTypeToDPXOrientation): Return U16 type as stored in DPX format.
> - coders/cineon.c: Add support for reading/writing 'orientation' setting.
> - coders/mpc.c: Add support for reading/writing 'orientation' setting.
> - coders/miff.c: Add support for reading/writing 'orientation' setting.
> - Rotate ChangeLog for 2012 and update web page copyright years.
