QuickTime 4 Reference

ColorSync Support

ColorSync is a system extension that provides a platform for consistent color reproduction between widely varying output devices. ColorSync color matching capability was added to the Image Compression Manager picture drawing functions in QuickTime 1.6.1. You can now accurately reproduce color images (not movies) with the DrawPicture functions by setting the useColorMatching flag in the flags parameter to these functions.



 
enum {

    useColorMatching    = 4

};
