I have 1 bit CCITT 4 compressed TIFFS. I can save these efficiently, but as soon as I modify the image using the graphics drawstring method to stamp some text on the image, I have to convert the image to 1bit to get it to save back using the CCITT 4 compression.

This operation takes several seconds and when I'm working with several pages, the operation to save a multi-page tiff is significant.

So my question, how can I get it to keep my image manipluations of text / graphic stamping to be 1 bit so I don't need to do the conversion?

You can try to draw text strings on 1bpp indexed images. It should work. But you have to resave it to TIFF with CCITT4 compression.
