There might be a bug in cairo or pixman because it doesn't seem to like the tiling pattern matrix. It doesn't draw anything if the matrix offset / scaling > 32768. It should still be fixed in poppler though, because it doesn't make sense to create a 9720x9720 pattern to fill a 750x500 area. Attached patch calculates the dimensions of the pattern after transformation and creates a pattern of the appropriate size.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
