Chapter 3 - ColorSync Manager Reference for Applications and Device Drivers
This reference document describes the constants, data structures, and functions defined by the ColorSync Manager for use by your application or driver. The ColorSync Manager allows your application or driver to maintain consistent color across devices and across platforms. You can use the ColorSync Manager for color conversion, color matching, color gamut checking, profile management, and creating color management modules (CMMs) that perform these services.
