This is an openjpeg problem.

The differences are > small but some of the important features are missing from OpenJpeg. > For instance, OpenJPEG doesn't recognize CMYK data. > Is there any plans to extend the library to support JPX? *sigh* So the options are: 1) Implement CMYK JPX support in openjpeg 2) Implement CMYK JPX support in Poppler's own JPX stuff 3) Give up and cry, it is only one PDF (I hope)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
