## Member Typedef Documentation

typedef vtkImageActor vtkOpenGLImageActor::Superclass

| Reimplemented from vtkImageActor. Definition at line 51 of file vtkOpenGLImageActor.h.

## Constructor & Destructor Documentation

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

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

## Member Function Documentation

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

| Instantiate the image actor. Reimplemented from vtkImageActor.

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

| Reimplemented from vtkImageActor.

int vtkOpenGLImageActor::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 vtkImageActor.

virtual int vtkOpenGLImageActor::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 vtkImageActor.

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

| Reimplemented from vtkImageActor.

virtual void vtkOpenGLImageActor::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 vtkImageActor.

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

| Implement base class method. Reimplemented from vtkImageActor.

void vtkOpenGLImageActor::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 vtkProp.

unsigned char* vtkOpenGLImageActor::MakeDataSuitable | ( | int & | xsize,
|  | int & | ysize,
|  | int & | release
| ) | `[protected]`
