           Summary: Rendering quality of Evince is poorer than that of
                    Okular
           Product: poppler
           Version: unspecified
          Platform: Other
               URL: http://bugzilla.gnome.org/show_bug.cgi?id=535377
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: glib frontend
        AssignedTo: poppler-bugs at lists.freedesktop.org
        ReportedBy: michel.sylvan at gmail.com


Evince and Okular use the same library to handle PDFs, but for some reason,
Okular's output is more smoothly anti-aliased. There does not seem to be any
applicable setting, both in the menus and using gconf-editor, to adjust how
much anti-aliasing is done in Evince.


Steps to reproduce:
1. Open a PS or PDF document (preferably older and scanned, rather than
LaTeX-generated)
2. Open the same document in Okular
3. Set zoom level to Fit Width in both and compare (the documents are otherwise
very different in size at the same zoom level. Bizarre)


Actual results:
Okular's output looks much better anti-aliased -- and does not render any
slower

Expected results:
Both outputs should be equivalent in quality -- okular uses poppler-qt4 for
rendering, evince uses poppler-glib

Does this happen every time?
Yes

Other information:
This is on Fedora 9; Evince maintainer identified this as a Poppler bug (see
URL)
