I found a discussion of black point compensation, and figured out that lcms2 has a special option for it. I set it in this patch, and great, the output is black again. But I'm not sure wether really set it globally everytime, under wether circumstances or make it an option. See i.e. gimp, <a href="https://mail.gnome.org/archives/commits-list/2013-December/msg01573.html">https://mail.gnome.org/archives/commits-list/2013-December/msg01573.html</a>. They made it an option. I haven't regtested my patch, I just proofed that it restores the desired output for the said PDF and want to show You that. Therefore I also titled this patch as experimentell. At least You should see that my implementation of the usage of default colorspaces should be correct and the problems with the said PDF have nothing to do with it.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
