Created attachment 57654 align fills Here's an experimental patch for the cairo backend. It doesn't completely solve the problem but it does eliminate the seams in some cases.
Some test cases I tried it with: https://bugs.launchpad.net/ubuntu/+source/poppler/+bug/348679/+attachment/510918/+files/test.pdf Eliminates the seams sometimes depending on the resolution rendered at. https://bugs.launchpad.net/ubuntu/+source/poppler/+bug/318130/+attachment/441616/+files/seminar1.pdf Seems to eliminate the seams at all resolutions I tested. https://bugs.launchpad.net/ubuntu/+source/poppler/+bug/387016/+attachment/606341/+files/Evince%20incorrect%20rendering.zip Eliminates the seams for all resolutions I tested except 150ppi where the one seam is worse. This is because the the coordinates of the adjacent fill where the line is worse are not identical (0.1 difference vertically). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to poppler in Ubuntu. https://bugs.launchpad.net/bugs/318130 Title: Horizontal lines appear on blue background on pdf Status in Poppler: Confirmed Status in “poppler” package in Ubuntu: Triaged Bug description: Binary package hint: evince We have a pdf file exported from Open Office Impress. The background is blue and there are horizontal lines through the image. The lines vary somewhat in colour, going from white to the blue. If the slide show is made in OO Impress, all is well (showing that this isn't a hardware problem). Likewise if the same exported pdf file is shown on Windows XP, all is well. The problem only appears in Evince 2.24.1 in Ubuntu 8.10. We cannot use Evince for the slide show because of these ugly lines.
