Hello,
I have a jpeg 2000 file with an ICC profile.
PCS is cmsSigXYZData and color space is cmsSigGrayData.
The file can be found here:
https://github.com/GrokImageCompression/grok/issues/38
I am working on a library that decodes the jpeg 2000 file and applies the
ICC profile, using LCMS.
Currently, I have this code:
in_type = TYPE_GRAY_8;
out_type = TYPE_RGB_8;
out_prof = cmsCreate_sRGBProfile();
and I can create the transform and apply the ICC profile, but the output is
an RGB file.
What I would like is to output a grayscale file.
So, if I instead call
out_prof = cmsCreateGrayProfile(NULL,NULL);
then cmsCreateTransform returns NULL and I can't apply the profile.
What is the best way of creating a transform for this kind of grayscale
image ?
Thanks so much,
Aaron
