Last comment: hidden here is actually a bug in whichever viewers were
not showing incorrect colors since the problem was in the PDF file, not

If you want an easy way to look into a PDF file, I recommend my qpdf
software, though in this case, you could look at the image dictionary in
the PDF file in a text editor. Solving this one required some
familiarity with the PDF spec.

xpdf viewer renders wrong colors for jpeg encoded images
Hello. I'm just looking over the tiff bugs in ubuntu. I'm the debian
tiff maintainer. Sorry you guys spent so much time on this. I was
already familiar with this problem. The problem is that tiff2pdf was
setting the /ColorTransform field to 0 in /DecodeParams when it should
not have been.
Colors are messed up on x86 hardware as well (under Gutsy). Also,
colors_z.pdf show up in the wrong order in both xpdf and evince, so even

Bugs,
well...
I've just tried Leopard's Preview application, for which the tiff and
the .pdf files show with the expected proper colors
on the other hand, I've also tried the latest Acrobat Reader 8.1.2, for
which colors_z.pdf is fine as well, but colors_j.pdf shows up with bad

Package changed to libtiff-tools
** Changed in: tiff (Ubuntu)
Sourcepackagename: xpdf = tiff
