Quartz Composer Reference Collection

The Quartz Composer Reference Collection defines Objective-C classes that, in one way or another, work with compositions built using the Quartz Composer development tool. The classes support the following programming tasks:

• Load, play, and control compositions stored as Quartz Composer files (qtz extension). See the QCView and QCRenderer classes.

• Access and render compositions that are stored in a system-wide repository. See the QCCompositionXXX classes.

• Load and play a composition in a Core Animation layer. See the QCCompositionLayer class.

• Create a custom patch that can be used from the Quartz Composer development tool. See the QCPlugInXXX classes.
