Data Transfer Commands
Specify commands for caller-supplied ColorSync data transfer functions.
Overview
When your application calls the function CMFlattenProfile, any of the functions in the group Accessing Profile Elements, or the PostScript-related functions of type Working With PostScript, the selected CMM—or, for the CMUnflattenProfile function, the ColorSync Manager—calls the flatten function you supply to transform profile data. The call passes one of the command constants defined by this enumeration.
Your application provides a pointer to your ColorSync data transfer function as a parameter to the functions. The ColorSync Manager or the CMM calls your data transfer function, passing the command in the command parameter. For more information on the flatten function, see CMFlattenProfile.
