Re: [Lcms-user] ColorSync/AdobeCMM et al. (“Slope Limit”) compatibility patch for Little CMS

OK, s I circumvented Adobe’s awkward CMM installer and installed the Adobe CMM manually on OS X – so that I could compare it with Little CMS wrt/ its TRC behavior. I also had to reimplement my test program, since the Adobe CMM is 32 bit only, whereas Apple’s current version of ColorSync is
