Programming With QuickTime Sprites

Using the Sprite Media Handler

The sprite media handler provides functions that allow an application to create and manipulate a sprite animation as a track in a QuickTime movie.

The following sections are illustrated with code from the sample program QTWiredSprites.c , which creates a 320 by 240 pixel QuickTime movie with one sprite track. The sprite track contains six sprites, including two penguins and four buttons. The sample program, which takes advantage of wired sprites, is explained in greater detail in Chapter 3, "Wired Sprites." Its full code is listed in Appendix C.
