           Summary: pdftops sometimes creates an image reference without the
                    image data
           Product: poppler
           Version: unspecified
          Platform: All
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
        AssignedTo: poppler-bugs at lists.freedesktop.org
        ReportedBy: imc at comlab.ox.ac.uk


Created an attachment (id=18984)

PDF file that produces broken PostScript with pdftops

The attached PDF is a page containing a large bitmapped letter H (and a small
bitmapped number 1).  It displays correctly with evince, xpdf, gv and Adobe
Reader.  However, pdftops generates a PostScript file containing the undefined
symbol ImData_9_0 because for some reason the image data for this object did
not get written to the PostScript file.  Inspection of the generated PostScript
shows that the data for the big letter H is not present, although the data for
the small number 1 is present.

This applies to poppler version 0.8.1 from the Fedora 9 distribution (but it
also fails in the same way with 0.5.4 from Fedora 7).

The PDF file was created with "ps2pdf" from GhostScript 8.15.4 on a Fedora 7
system (from a 3-line TeX file and "dvips -Ppk").  I note that GhostScript 8.62
produces a different PDF which pdftops can print without error, but I'm not
sure what the difference is.
