OK, this time for sure. The image ftp://ftp.quitt.net/TIFF/00001901.tif is slightly ill. It displays properly, but it's the only image I've ever seen that when expanded and recompressed by libTIFF has completely different image data (with all parameters the same). If the data is placed into a PostScript document GCView won't even show it. If I put the recompressed data into the document instead, it displays and prints properly.

I'm telling the user that the TIFF is bad and that the vendor should be notified. I've also added an option that forces the program to expand and compress the image for use, so printing continues

But what is wrong with the TIFF? Or what am I (and PostScript) missing?
