Abstract
A color engine supports extensibility by allowing plug-ins. The color engine transforms an image file associated with a source device for consumption by a destination device. Within the color engine, a device model operates over a device model profile to generate a gamut boundary shell, which describes the range of colors a device is capable of producing. A color appearance model operates over a color appearance model profile to compensate for external viewing conditions. A gamut map model accepts as input gamut boundary shells describing the source device and the destination device, and operates over a gamut map model profile to generate a transform, which is used to transform the image file for consumption by the destination device. The device model profiles and gamut map model profiles may be extended using XML plug-ins, and the device models and gamut map models may be extended using DLL plug-ins.
