--- Comment #11 from Buovjaga <[email protected]> --- (In reply to Gabor Kelemen (allotropia) from comment #10) > A possible option could be to (re?)use the http://www.openjpeg.org/ library, > which seems to me having some level of support for CYMK support[1] since > quite some time (2014), and has 2-clauses BSD license[2]. > > [1] https://github.com/uclouvain/openjpeg/pull/559/files > [2] https://github.com/uclouvain/openjpeg/blob/master/LICENSE > > @Tomaz: any thought on this direction? libjpeg-turbo also supports CMYK, but it leaves colour management as an exercise for the user: https://github.com/libjpeg-turbo/libjpeg-turbo/blob/895287572db62318332a78395a0c07eb86137fd8/turbojpeg.h#L289 "In order to convert between CMYK and RGB, it is necessary to use a color management system (CMS.) A CMS will attempt to map colors within the printer's gamut to perceptually similar colors in the display's gamut and vice versa, but the mapping is typically not 1:1 or reversible, nor can it be defined with a simple formula. Thus, such a conversion is out of scope for a codec library." In that openjpeg commit I see they use liblcms2, which we also have as a dependency. -- You are receiving this mail because: You are the assignee for the bug.
