Road Map to QuickTime 4

The Sprite Toolbox

This chapter discusses the sprite toolbox which is a set of data types and functions you can use to add sprite-based animation to an application. The sprite toolbox is used by applications creating sprite animations outside of QuickTime movies and handles the following:

• invalidating appropriate areas as sprite properties change
• the composition of sprites and their background on an offscreen buffer
• the transfer of the result to the screen or to an alternate destination

To use sprite animation in a QuickTime movie, you create a sprite track and media samples used by the sprite media handler. For information on how to use the sprite media handler, see The Sprite Media Handler

This chapter is aimed at developers who are using the lower-level sprite toolbox APIs to create sprite animations in their applications, not in a QuickTime movie.
