Managing Color With ColorSync


Gamut Checking

Because not all colors can be rendered on all devices, you may want your application to warn users when a color they choose is out of gamut for the currently selected destination device. For example, you can use gamut checking to see if a given color is reproducible on a particular printer. If the color is not directly reproducible--that is, if it is out of gamut--you can alert the user to that fact. The ColorSync Manager provides the CWCheckPixMap and CWCheckColors functions for checking a color against a device's profile to see if it is in or out of gamut for the device. Your application can then display the results of this check to the user.
