Hi,
I new to lcms and c programming.
I'm have written simple program that reads Lab values for given CMYK
values. The core of program looks like that:
xform = cmsCreateTransform(hProfile, TYPE_CMYK_DBL, hLab, TYPE_Lab_DBL,
INTENT_ABSOLUTE_COLORIMETRIC, 0);
cmsDoTransform(xform, &CMYK, &Lab, 1);
so 4 element CMYK array gives me Lab values. I have CMYK values form 0 to
100.00
Now i need to extend it o read not only from CMYK profiles but also from
other prtr profiles including 6CLR profiles. I'm able to list all named
colors from profile, but I dont know how to get lab values for 6 element
input array.
The problem is probably easy but I do not know what to pass to
cmsCreateTransform instead of TYPE_CMYK_DB for 6CLR profile. I found
TYPE_NAMED_COLOR_INDEX but it seems to work on single channel, not 6
channels. Can anyone help me?
