I saw the same thing when I tried it. What I realized (using a different converter called tiff2sun) was that it assumed that each horizontal line of the image was padded to the end of the word (16 bits) just like a Sun rasterfile is, but the TIFF files I scanned on a Mac were only padded to the next byte, thus causing the skewing. When I corrected the code to account for the differences in padding, it worked. I assume something similar is wrong with tif2rast, but I have not had the ambition to go back and look. -- --------------------------------------------------------------------------- Bill Barbiaux | GE Medical Systems gemed!links!barbiaux@crd.ge.com | PO Box 414 sun!sunbird!gemed!links!barbiaux | Milwaukee, WI 53188
