Leopard Sample Code: Graphics & Imaging
Cocoa provides classes for custom drawing based on Quartz graphics, and utility functions for common graphics tasks such as copying and drawing bitmap data. To go beyond what Cocoa provides, developers can use the graphics and imaging frameworks in Mac OS X. Cocoa applications have access to a wide variety of graphics technologies including Quartz 2D, Quartz Services, OpenGL, QuickTime, and the Mac OS X printing system.
