Therefore the softmask knocks out everything instead of just remove the background transpareny. The patch solves it for splash, probably it's quite easy to do the same in cairo for a cairo specialist. BTW, the patch also changes the output for some defect PDFs in my PDF suite (bug-poppler30228.pdf, bug-poppler10910.pdf, tauya.f8.pdf), but because they are damaged I couldn't compare the output with acrobat.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
