Abstract
Conversion of colors of an image from a source color space to a destination color space by use of both a color profile and an image profile. The source and destination color spaces are respectively represented by source and destination color space transformations associated with source and destination color profiles. Colors in an image are converted from the source color space to a device-independent color space, using the source color space transformation. A gamut mapping is determined from a source color gamut to a destination color gamut, by using a gamut boundary description constructed either from a source image profile which is separate from the source color profile, or from a destination image profile which is separate from the destination color profile. The gamut mapping is applied, and the gamut mapped colors are transformed from the device-independent color space to the destination color space, using the destination color space transformation.
