## Member Function Documentation

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

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

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

| Reimplemented from vtkImageMapper.

int vtkOpenGLImageMapper::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 vtkImageMapper.

virtual int vtkOpenGLImageMapper::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 vtkImageMapper.

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

| Reimplemented from vtkImageMapper.

virtual void vtkOpenGLImageMapper::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 vtkImageMapper.

void vtkOpenGLImageMapper::RenderOverlay | ( | vtkViewport * | viewport,
|  | vtkActor2D * | actor
| ) | `[inline, virtual]`

| Handle the render method. Reimplemented from vtkMapper2D. Definition at line 58 of file vtkOpenGLImageMapper.h. References vtkImageMapper::RenderStart().

void vtkOpenGLImageMapper::RenderData | ( | vtkViewport * | viewport,
|  | vtkImageData * | data,
|  | vtkActor2D * | actor
| ) | `[virtual]`

| Called by the Render function in vtkImageMapper. Actually draws the image to the screen. Implements vtkImageMapper.
