Base class for images

Inheritance:

RasterBase

Public Methods

virtual void*	getPointer () Get the pointer to the data to be passed to the gl routines.
virtual RasterBase*	clone () Clone this raster; create a new one with the same measurements and content in the free store
virtual void	setGLPixelModes () Set the OpenGL pixel store modes for this raster.

virtual void* getPointer() = 0

Get the pointer to the data to be passed to the gl routines. The only legal operation with this pointer is Giving it to an OpenGL routine which expects width * height bytes of data after calling setGLPixelModes to set the appropriate modes.

virtual RasterBase* clone() = 0

Clone this raster; create a new one with the same measurements and content in the free store

virtual void setGLPixelModes() = 0

Set the OpenGL pixel store modes for this raster. If you want to save and restore the state prior to this, use glPushClientAttrib.
