## Member Typedef Documentation

typedef vtkTexture vtkOpenGLTexture::Superclass

| Reimplemented from vtkTexture. Definition at line 53 of file vtkOpenGLTexture.h.

## Constructor & Destructor Documentation

vtkOpenGLTexture::vtkOpenGLTexture | ( |  | ) | `[protected]`

vtkOpenGLTexture::~vtkOpenGLTexture | ( |  | ) | `[protected]`

## Member Function Documentation

vtkOpenGLTexture* vtkOpenGLTexture::New | ( |  | ) | `[static]`

| Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkTexture.

virtual const char* vtkOpenGLTexture::GetClassName | ( |  | ) | `[virtual]`

| Reimplemented from vtkTexture.

int vtkOpenGLTexture::IsTypeOf | ( | const char * | type | ) | `[static]`

| Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkTexture.

virtual int vtkOpenGLTexture::IsA | ( | const char * | type | ) | `[virtual]`

| Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkTexture.

vtkOpenGLTexture* vtkOpenGLTexture::SafeDownCast | ( | vtkObject * | o | ) | `[static]`

| Reimplemented from vtkTexture.

virtual void vtkOpenGLTexture::PrintSelf | ( | ostream & | os,
|  | vtkIndent | indent
| ) | `[virtual]`

| Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkTexture.

void vtkOpenGLTexture::Load | ( | vtkRenderer * | ren | ) | `[virtual]`

| Implement base class method. Reimplemented from vtkTexture.

void vtkOpenGLTexture::ReleaseGraphicsResources | ( | vtkWindow * |  | ) | `[virtual]`

| Release any graphics resources that are being consumed by this texture. The parameter window could be used to determine which graphic resources to release. Using the same texture object in multiple render windows is NOT currently supported. Reimplemented from vtkTexture.

unsigned char* vtkOpenGLTexture::ResampleToPowerOfTwo | ( | int & | xsize,
|  | int & | ysize,
|  | unsigned char * | dptr,
|  | int | bpp
| ) | `[protected]`
