The ColorSync Manager is the API for ColorSync, a platform-independent color management system from Apple. ColorSync provides essential services for fast, consistent, and accurate color calibration, proofing, and reproduction using input, output, and display devices. ColorSync also provides an interface to system-wide color management settings that allows users to save color settings for specific jobs and switch between settings.
You need this reference if your software product performs color drawing, printing, or calculation, or if your peripheral device supports color. You also need this reference if you are creating a color management module (CMM)—a component that implements color-matching, color-conversion, and gamut-checking services.
The Color Picker Manager, documented separately, provides a standard user interface for soliciting color choices.
Carbon supports the majority of the ColorSync Manager programming interface. However, ColorSync 1.0 compatibility calls such as
Set are not supported.
Nor does Carbon support ColorSync functions used for color management modules (CMMs). These functions aren't supported because macOS uses Bundle Services to implement CMMs.
Some applications use the Component Manager to determine what CMMs are available. You cannot use the Component Manager for this purpose in macOS. Apple has, however, provided the function
CMIterate to query for available CMMs.
