             Bug #: 46708
           Summary: File name pattern output by pdftoppm doesn't match
                    documentation
    Classification: Unclassified
           Product: poppler
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: utils
        AssignedTo: poppler-bugs at lists.freedesktop.org
        ReportedBy: alexandre.magaz at udl.cat


pdftoppm's man page says:

  Pdftoppm reads the PDF file, PDF-file, and writes one PPM file for each page,
PPM-root-nnnnnn.ppm, where nnnnnn is the page number.

but the length of the page number string (nnnnnn) isn't 6 but variable. This
breaks programs which expect it to have a fixed length.

The change was introduced in the following commit:

http://cgit.freedesktop.org/poppler/poppler/commit/utils/pdftoppm.cc?id=3ba088d8caee3c40c2aba0cd85adcf9195ae88a3

The snprintf format string was changed from "%.*s-%06d.%s" to "%.*s-%0*d.%s".
