             Bug #: 48964
           Summary: Slow rendering of pdf with a lot of image masks in
                    pattern colorspace
    Classification: Unclassified
           Product: poppler
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: splash backend
        AssignedTo: poppler-bugs at lists.freedesktop.org
        ReportedBy: Thomas.Freitag at alfa.de


I got a PDF with 12153 image masks in pattern colorspace. Rendering it with
pdftoppm under Windows stops after after over 20 minutes with out of memory.

The implementation of rendering image masks in pattern colorspace should be
optimized in the splash backend.
