The output needs to be black and white, but I get this gaining or losing of edges when I convert out of deep color. Should that vary with the format? So that BPM might work better than JPG?
JPEG
cannot store B&W images. JPEGs are either 8-bit (grayscale) or 24 bits and is a poor choice for storing B&W material.
GIF, BMP, and PNG can store B&W. One of the most effective way to store B&W is to use TIFF with CCITT FAX4 encoding. A page that is a megabyte saved as BMP will shrink to a few kilobytes when saved as TIFF CCITT FAX4. (PMView can do this!)
Thanks,
