A friend of mine was using Sam Leffler's TIFF library code from Berkeley (version 5.0 of TIFF). This seems to be most commonly used for TIFF conversion. He wanted to port the code onto a MacII. He got the uncompressed version of TIFF working fine. However, he's been having trouble with the LZW compression variation of TIFF. TIFF LZW images generated from the library source are not understood by other Mac software (e.g. Photoshop, Ultra-Paint...); and TIFF LZW images generated from other Mac software are not understood by this library source (tiffInfo tells him that the header is fine, but the program quits on either scanline 0 or 1 from the complaint of missing data). My friend doubts that there is a bug in the source. However, has anyone else encountered this problem with LZW compression? And is version 5.0 of TIFF the latest version number - perhaps a difference in version numbers might explain his discrepencies? Any help in this area is very much appreciated.
