I'm reporting the bug here, since on the libtiff web site (http://www.libtiff.org/bugs.html), the link to the bug traker is broken:
That's the "old" domain before it was hijacked. Now look for:
http://remotesensing.org/libtiff/
Ah, ok; thanks.
The problem is with tiff2pdf writing two times the WhitePoint entry in the Lab dictionary:
/ColorSpace [/Lab <<
/WhitePoint
[0.9643 1.0000 0.8251]
[0.9643 1.0000 0.8251]
> /Range [-127 127 -127 127]
>
>>> ]If you look at the code this appears to be intentional:
Are you sure that this is the problem? Are you sure that it's not something else?
Yes, I'm sure.
Try to convert this image: http://www.colour.org/tc8-03/images/ski_pg/Ski_TC8-03_abs.tif
It will fails to open with Acrobat Reader.
Ghostscript will report an human readable error:
File has an unbalanced >> (close dictionary).
Removing the duplicate [0.9643 1.0000 0.8251] solves the problem; since it is not valid PDF syntax.
Thanks,
Lee.
