             Bug #: 45441
           Summary: Fix return value of downscale_box_filter()
    Classification: Unclassified
           Product: poppler
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: cairo backend
        AssignedTo: poppler-bugs at lists.freedesktop.org
        ReportedBy: hib at hiberis.nl


Going through the warnings while compiling poppler, I noticed the retval
variable in downscale_box_filter() was not used at all. I think it should
actually be used as the return value.

Patch follows.
