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?

Hello,

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.
Sincerely yours,
