Color World Reference

Your application passes a color world reference as a parameter on calls to functions to hold color-matching and color-checking sessions and to dispose of the color world. When your application calls the NCWNewColorWorld function (page 3-108) and the CWConcatColorWorld function (page 3-110) to allocate a color world for color-matching and color-checking sessions, the ColorSync Manager returns a reference to the color world. The ColorSync Manager defines an abstract private data structure of type CMPrivateColorWorldRecord for the color world reference.

struct CMPrivateColorWorldRecord *CMWorldRef;

The color world is affected by the rendering intent (page 3-35), lookup flag (page 3-29), gamut flag (page 3-29), and quality flag (page 3-33) of the profiles that make up the color world.
