Programming With QuickTime Sprites
| Previous | Chapter Contents | Chapter Top | Next |
The sprite toolbox is a set of data types and functions you can use to add sprite-based animation to an application. The sprite toolbox handles invalidating appropriate areas as sprite properties change, the composition of sprites and their background on an offscreen buffer, and the transfer of the result to the screen or to an alternate destination.
To create a sprite track in a QuickTime movie, you create media samples used by the sprite media handler, which, in turn, makes use of the sprite toolbox. For information on how to use the sprite media handler, see Chapter 2, "Sprite Media Handler."
