All color tuning, including brightness, contrast and gamma also work in the Dithered mode (in the Avision backend). Btw. Why do you use dithered at all? If you want automatic thresholding you can scan in Gray (or Color) and use optimize2bw from ExactImage: http://www.exactcode.de/site/open_source/exactimage/econvert/ http://www.exactcode.de/site/open_source/exactimage/utilities/ Yours, -- Ren?
