Inside Macintosh: Advanced Color Imaging on the Mac OS /

Chapter 7 - Color Manager

The Color Manager assists Color QuickDraw in mapping your application's color requests to the actual colors available. Most applications never need to call the Color Manager directly. The material in this chapter is provided for specialized applications that require a color-mapping method other than the one used by the Color Manager.

You need to understand Color QuickDraw concepts, terminology, and data structures when using the material in this chapter. You should be familiar with RGB color values, color tables, pixel maps, and graphics devices, as described in Inside Macintosh: Imaging With QuickDraw.

Color Manager functions are the intermediary between such high-level software as Color QuickDraw, the Palette Manager, and the Color Picker Manager, and the lower-level of video cards and screens. The vast majority of applications never need to use Color Manager functions directly.
