             Bug #: 44572
           Summary: PS backend has too high memory requirements (much
                    higher than PDF or SVG)
    Classification: Unclassified
           Product: cairo
           Version: 1.10.2
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: postscript backend
        AssignedTo: ajohnson at redneon.com
        ReportedBy: petr.dlouhy at email.cz

I am trying to generate large (i.e. 6740x4768 points) vector map outputs with
Mapnik in a <a
href="https://sourceforge.net/p/pnkmap/code/ci/ee6b8efd35844e27fa78ce8c6c58ac206c8e291c/tree/Devel/export/export.py">Python
script</a>, but Cairo is unable to generate large PostScript files due to high
memory consumption (>4GB), where PDF files could be generated with much lower
(~500MB) requirements.
