Detailed Description

Implementation of PixelCanvasColorTable for OpenGL.

Synopsis

GLPixelCanvasColorTable is an X11PixelCanvasColorTable that has been modified to work within the constraints of the GLPixelCanvas. (e.g. Not assuming the default visual).

Colormap values are written to a virtual colortable (an internal array). For Indexed (PseudoColor) windows, the values are sent to the hardware colormap. For RGB (TrueColor) windows, the virtual colortable is used to emulate a hardware lookup table.

Prerequisite

• PixelCanvasColorTable
• How to get the X Screen pointer.

Etymology

Thrown Exceptions

Intended use:

Public interface

Colormap entry for the virtual colormap.
