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.

Abstract: Systems and methods for providing consistent chromatic adaptation to a workflow comprising a number of International Color Consortium (ICC) profiles is provided. In accordance with an exemplary method of the present invention, the profiles within the workflow that require chromatic adaptation are identified. A control profile, whose chromatic adaptation method will be applied to the other profiles identified as requiring chromatic adaptation, is also identified. The chromatic adaptation method of the control profile is determined. The color data of the each profile identified as requiring chromatic adaptation is then converted using the chromatic adaptation method of the control profile such that all profiles requiring chromatic adaptation have been chromatically adapted using the same method.

Abstract: Palette-based, multi-tint, named-color methods and systems utilize a pixel-by-pixel indexing technique in which individual index values into a palette of interest can be used in different ways for rendering associated images across different devices. For some devices, the index values are used to index into the palette of interest to ascertain a specific indexed color value that is then used to render that pixel of the associated image. For other devices, the index value is used as a means to compute a color value that these other devices then use to render that pixel of the associated image.
