Color QuickDraw Routines

This section describes Color QuickDraw's routines for creating and closing color graphics ports, managing a color graphics pen, changing the background pixel pattern, drawing with Color QuickDraw colors, determining current colors and best intermediate colors, calculating color fills, creating and disposing of pixel maps, creating and disposing of pixel patterns, creating and disposing of color tables, customizing Color QuickDraw operations, and reporting to QuickDraw that your application has directly changed those data structures that applications generally shouldn't manipulate.

To initialize Color QuickDraw, use the InitGraf procedure, described in the chapter "Basic QuickDraw." Besides initializing basic QuickDraw, this procedure initializes Color QuickDraw on computers that support it.

In addition to InitGraf, all other basic QuickDraw routines work with Color QuickDraw. For example, you can use the GetPort procedure to save the current color graphics port, and you can use the CopyBits procedure to copy an image between two different color graphics ports. See the chapters "Basic QuickDraw" and "QuickDraw Drawing" for descriptions of additional routines that you can use with Color QuickDraw.
