I'm building a DVL profile using icclink and I'd like to build a custom gamut mapping for a specific image using the gamut generated with tiffgamut. My question is, if I use "icclink -ip -G image.gam", am I compressing the gamut twice?
No you're not, since the -g and -G options both make used of the colorimetric tables only (in fact the -G makes use of only the A2B colorimetric table). That's the point, -g or -G generates a link specific gamut mapping, rather than using the gamut mappings encoded in the profile tables. In -g or -G modes, the -i parameter determines the type of gamut mapping generated, rather than choosing which profile tables to use, which is why there is only one of them (-i) rather than the two (-i and -o) in simple mode.
