In article <1992Aug24.160817.2595@ms.uky.edu> soward@slow.inslab.uky.edu (John Soward) writes re optional tiff compression: > In real-world usage, packbits seems to perform poorly, but lzw does > okay--but not really much better than using compress (also lempel-ziv) on the > tiff file (but then you have to actually issue uncompress to open it ;-) The big difference is that an lzw-compressed tiff file is still (supposed to be) usable as a tiff, while the foo.tiff.Z output by compress is not. For example. if you lzw-compress a tiff image using tiffutil, you can still import the compressed tiff into FrameMaker and it will display correctly. (This can have a MAJOR effect on Frame document size!)
