Functions Affected by Imaging Extensions

Functions Affected by Imaging Extensions

Imaging extensions affect all functions that are affected by the pixel transfer modes (see "Storing, Transforming, and Mapping Pixels" in Chapter 8, "Drawing Pixels, Bitmaps, Fonts, and Images," of the OpenGL Programming Guide). In general, these are all the commands that draw and copy pixels or define texture images and all commands that read pixels or textures back to host memory.
