I'll look at PNG. I also plan to try TIFF + zlib, and even making an
uncompressed TIFF then bzip'ing it. In some experiments, I got surprisingly
good results with JPEG. I can't of course use a heavy degree of
quantization, but I was surprised at how much compression I could get before
artifacts started showing up. I think part of it is that with scanned images
the edges are already slightly "softened" by the aliasing inherent in the
sampling, as opposed to a computer-generated original where many edges may
be absolute.
