Exactly right. The power of Unix... ;-)

Right, which is something I'd rather prefer to avoid. The GIMP is the
right solution here, IMHO (though I think the GIMP is currently
lacking in its ability to print images, but that's just another
plug-in, after all).

Andy> ToGif : ppmtops %f >%f.gif - convert to gif
Andy> ...

I kind of like this idea. This might be useful to people that don't
want to use the GIMP. I'd love to see this implemented for
stand-alone mode. Doesn't seem very difficult either. As a minor
nit, it seems to me it would be more natural if those command buttons
would both _scan_ and _process_ image (through a user-defined pipe).

On the note of implementing things: due to other commitments, I won't
be able to implement any (non-trivial) new features over the next
couple of months (after that, I'll be getting a Real Job and it's not
clear yet what's going to happen, but I'll definitively try to make
time for SANE). However, in the meantime, I do promise to integrate
"good" patches and make bug fixes etc as time permits.
