I try to read/view a tiff file with different Viewers for HP-UX. All these Viewers depent on libtiff. I got the newest version available for HP-UX 10.20, which is 3.5.4, but i still can't load these images. Here are the outputs from tiffinfo, tiffdump and the errormessage from xtiff:

b077:/opt/tiff-3.5/bin$ ./tiffinfo

TIFF Directory at offset 0x8

TIFFFillStrip: /caddaten/BS/cadtransfer/cad/test2.tif: Read error at scanline 4294967295; got 72088 bytes, expected 72096.

Unfortunately i have no influence in generating these images, so i have to take what i get. Is there a way to read/view these files with libtiff? As viewers i tried gview, ImageMagick, xtiff and gimp which all depend on libtiff and all failed to open these files.

Im no programmer, so if there is a solution to this problem and i have to edit/compile the sources, i need detailed instructions.

Any help would be greatly appreciated. (Hope my english was good enough to describe my problem)
