May the xicclu have a deal with device link profiles? For example: xicclu -ff Link1.icm 0.000000 0.000000 0.000000 [In_RGB] -> Lut -> 0.013754 0.014328 0.018994 [Out_RGB] xicclu -fif Link1.icm 0.013754 0.014328 0.018994 [Out_RGB] -> Lut -> 0.000000 0.000019 0.000002 [In_RGB] xicclu -ff -Link2.icm 0.000000 0.000000 0.000000 [In_RGB] -> Lut -> 1.000000 0.906763 0.548572 1.000000 [Out_CMYK] I've wanted such feature while experimenting with gamut mapping.
