Your application uses the QuickDraw PicComment function, described in Inside Macintosh: Imaging With QuickDraw , to specify picture comments for beginning or ending use of an embedded profile, turning color matching on or off, or embedding a profile identifier. The following sections describe constants you use to perform these operations:
IMPORTANT
Use a picture comment of kind cmEndProfile to explicitly terminate use of the currently effective embedded profile and begin use of the system profile. Otherwise, the currently effective profile remains in effect, leading to unexpected results if another picture follows that is meant to use the system profile and so isn't preceded by a profile.
enum {
cmBeginProfile = 220, /* begins 1.0 profile */
cmEndProfile = 221, /* ends 2.x or 1.0 profile */
cmEnableMatching = 222, /* turns on color matching */
cmDisableMatching = 223, /* turns off color matching */
cmComment = 224 /* profile or profile identifier
is embedded */
};
