CMYK modeled PDFs display a color shift -- they become slightly more saturated than normal (see included image of Okular vs Google Chrome rendering; Google Chrome renders the colors accurately). The same problem appears in iBooks for iOS. Reproducible: Always Steps to Reproduce: 1. Open PDF with CMYK color model. I used my Histology textbook. 2. 3. Actual Results: Everything renders fine except for the colors. Expected Results: Everything should have rendered fine, including the colors. There should be no difference between the colors of a CMYK and RGB color model PDF.
Created attachment 94595 [details] an example of the problem using my Histology textbook pdf, in CMYK
Need an actual pdf to reproduce (i may also need new eyes since my slight color blindness won't help with this :D but let's worry about that later)
Created attachment 94609 [details] you can use this pdf to test it out
Could you point me (remember slightly colorblind) in attachment 94595 [details] what is wrong?
there's a shift of blue-violet that's prominently visible in the slides and the lines beneath the slide headings. it would be visible on any color, in any hue/saturation shift.
Now that i realize, sorry but this is not an okular bug, it is a poppler bug. poppler is the library we use to deal with pdf files, so if the rendering is wrong, it is on their side. Please report a bug at http://bugs.freedesktop.org/
oh ok will do :D thanks!
