* @brief 2D image display support for OpenGL
|
||
|
|
*
|
||
|
|
* vtkOpenGLImageMapper is a concrete subclass of vtkImageMapper that
|
||
|
|
* renders images under OpenGL
|
||
|
|
*
|
||
|
|
* @warning
|
||
|
|
* vtkOpenGLImageMapper does not support vtkBitArray, you have to convert the array first
|
||
|
|
* to vtkUnsignedCharArray (for example)
