           Summary: pdftops -tiff -overprint fails with TiffWriter: Mode 6
                    not supported
    Classification: Unclassified
           Product: poppler
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium

Created attachment 67128
  --> https://bugs.freedesktop.org/attachment.cgi?id=67128
patch to fix the problem based on git source from 14 Sep 2012

pdftoppm -tiff -overprint -singlefile x.pdf x
fails with
TiffWriter: Mode 6 not supported
because utils/pdftoppm.cc calls new SplashOutputDev() with mode
splashModeDeviceN8 if jpegcmyk or overprint is set and goo/TiffWriter.cc does
not handle that mode.
With the attached patch, pdftoppm produces a CMYK tiff.
