Is it? I thought the discussion was talking about
colour line-art. In
scanning, line-art means 1bpp, at least in my experience;
Only if you like your line art to be highly aliased! I've found that
8bpp grayscale does wonders for line art, unless you're lucky enough
to have line art that is entirely at multiples of 45 degrees and
you're also lucky enough to get the scanning grid to line up exactly
with the orientation of the line art and you're lucky enough that your
original doesn't have any stretch or creep in the way the line art was
originally printed (or if you have a photocopy of an original the copy
machine didn't introduce any stretching or other distortion).
I read
"colour line-art" as implying 1bpp per primary, giving an absolute
maximum of 8 different colours, well within GIF's range.
Again, I'd say this is an extremely simplistic way of looking at line
art.
PNG most certainly is not in all still-maintained
graphics programs.
For example, I have an image displayer in live use (which I'm still
maintaining) which supports nothing but pbm/pgm/ppm.
Yeah, but pngtopnm has been around for almost as long as png ;-).
Also, your image viewer doesn't support GIF either, so :-P.
