           Summary: poor rendering compared to gv - anti-aliasing options
                    wrong?
           Product: okular
           Version: unspecified
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: PS backend
        AssignedTo: okular-devel at kde.org
        ReportedBy: markus.parker at arcor.de


Version:            (using KDE 4.3.4)
OS:                Linux
Installed from:    openSUSE RPMs

The rendering of postscript file yields poor results compared to the program gv
on my screen. When looking at the anti-aliasing options of okular in
generator_ghostview.cpp I discovered that okular uses 2 bits for text alpha and
4 bits for graphics alpha, while gv uses 4 bits for text alpha and 2 bits for
graphics alpha. When I tell gv to do it the other way around, the result was as
poor as in okular.

On my Laptop display (1400x1050) there is hardly any  difference between okular
and gv, however on my usual screen (1050x1680), the visualization is kind of
ugly. I guess this is because of the higher resolution.
