Setting the ColorSync profile for a NSBitmapImageRep object
Q:
I'd like to associate a ColorSync profile with a given NSBitmapImageRep
object for color-matching purposes. Is there a simple way to do this?

You can associate a ColorSync profile with a -setProperty:
method and the NSImageColorSyncProfileData
property.
Here's a short code snippet showing how it's done:
Listing 1 Setting the ColorSync profile for a NSBitmapImageRep
object.
// // imageRepWithProfileAtPath // // Associate a given file-based ColorSync profile with // a NSBitmapImageRep object // // Inputs: // // aPath - file path for a ColorSync profile // // Outputs: // // - returns a new NSBitmapImageRep object, created // by copying the receiver and applying the ColorSync // profile. @implementation NSBitmapImageRep (MoreColorMethods) - (NSBitmapImageRep *) imageRepWithProfileAtPath:(NSString *) pathToProfile { id result = [self copy]; // build a NSData object for our ColorSync profile file id profile = [NSData dataWithContentsOfFile: pathToProfile]; // now set the ColorSync profile for the object [result setProperty:NSImageColorSyncProfileData withValue:profile]; return [result autorelease]; } @end |
