If so it is quite easy: from PIL import Image # # Assumptions: your .jpg files are 256 bit color (or grayscale) # im=Image.open(inputFile) im2=im.convert('1') # convert to black and white im2.save(outputFile, 'TIFF') where: inputFile is your .JPG file outputFile is your .TIF file then use: tiffcp -c g4 outputfile.tif outputfileG5.tif On the other hand, if you want to create multi-page tiffs it is quite a bit more complicated. This creates uncompressed TIF file. I've used NetPBM Hope this helps. -Larry _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
