5.6. More Information

OpenGL provides an incredibly rich set of routines for controlling how OpenGL unpacks pixel rectangles submitted by the application, as well as how it packs pixel rectangles to return to the application. Unfortunately, much of this functionality is outside the scope of OpenGL^® Distilled.

Chapter 8, "Drawing Pixels, Bitmaps, Fonts, and Images," of OpenGL^® Programming Guide covers this information in depth, including the imaging subset functionality available in the GL_ARB_imaging extension.

See the book's Web site for the PixelRectangle example program source code. The Extensions example program, discussed in Chapter 7, "Extensions and Versions," also demonstrates techniques for rendering pixel rectangles.
