Public bug reported: Using karmic and firefox-3.0, I printed a pdf of the following web page:
http://en.wikipedia.org/wiki/Subgroup (permanent link: http://en.wikipedia.org/w/index.php?title=Subgroup&oldid=296077109) If I print this pdf with evince (even printing to a pdf file) I get terrible quality and pages are converted to images. If I print it with okular, I get a good quality document, however a mathematical formula is obscured (bottom of page 3). In evince the formula is visible. Here is the pdf printed from firefox: http://launchpadlibrarian.net/28547865/groups.pdf The reprint from evince: http://launchpadlibrarian.net/28547874/a.pdf The reprint from Okular: http://launchpadlibrarian.net/28547885/b.pdf On this other bug report: https://bugs.edge.launchpad.net/ubuntu/+source/cupsys/+bug/150187 Adrian Johnson explained: The reason pages 1 and 4 of your PDF are printed as a bitmap are: - Firefox is using cairo operators that are not natively supported by PDF on page 1 and 4. I don't think there is any reason that Firefox needs to use anything other than CAIRO_OPERATOR_OVER when printing so I consider this a bug in Firefox. - As a result cairo embeds a fallback image in the PDF for the region drawn with operators not supported by PDF. But the bounding box of the PDF pattern used to draw the fallback image is set to the page size instead of the image size. This is a bug in cairo. - When poppler is used to print the PDF via the cairo backend the image becomes a full page image due to the pattern bounding box being set to the page size. ** Affects: poppler (Ubuntu) Importance: Undecided Status: New -- Very bad quality from evince printing pages which have been printed to pdf using firefox https://bugs.launchpad.net/bugs/394266 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
