6.12 Color Management Extensions

The Xlib color management facilities can be extended in two ways:

Device-Independent Color Spaces
Device-independent color spaces that are derivable to CIE XYZ space can be added using the XcmsAddColorSpace() function.
Color Characterization Function Set
A Color Characterization Function Set consists of device-dependent color spaces and their functions that convert between these color spaces and the CIE XYZ color space, bundled together for a specific class of output devices. A function set can be added using the XcmsAddFunctionSet() function.
