(mind you, I know there are easier ways to do this, but I ended up here because everything else I was trying wasn't working.. I wanted to ensure each page was definitely saved as CCITT4)
In Windows XP, this code will take an input multipage tiff, convert each page to B&W, boost the contrast a bit, and save to the output file. Each page of the target TIFF is saved as Group 4 Fax encoding. In Windows 7, only the first page of the multipage tiff is saved as CCITT4, the rest are saved as LZW.
