Managing Color With ColorSync


Profile Reference

The ColorSync Manager defines the CMProfileRef type to provide access to a specific profile.


CMProfileRef

A profile reference is the means by which your application gains access to a profile. Several ColorSync Manager functions return a profile reference to your application. Your application then passes it as a parameter on subsequent calls to other ColorSync Manager functions that use profiles.

The ColorSync Manager returns a unique profile reference in response to each individual call to the CMOpenProfile , CMCopyProfile , and CMNewProfile functions. This allows multiple applications concurrent access to a profile. The ColorSync Manager defines an abstract private data structure of type OpaqueCMProfileRef for the profile reference.
