More than one way to do it... That's what I was thinking...
Lemme try ImageMagick...
It turns out that ImageMagick does the same thing that the GIMP does...
produce a very low quality JPG...

Looks like
convert -quality 100 Pg13of13.pdf Pg13of13.jpg
is /supposed/ to do what you want
Check with
identify -verbose Pg13of13-test.jpg
These progs have a zillion options, maybe there's something else that
could do additional magick magic?
http://www.imagemagick.org/script/convert.php
file://localhost/usr/share/doc/ImageMagick-6.2.2.0/www/convert.html
Oh, BTW, gimp has an option for jpeg compression, too. But convert seems
like a nicer thing to script -- if it would only do what you want <heh>.

OK this is interesting... doing this:
convert -density 600% Pg13of13.pdf -quality 100% -resize 25%
Pg13of13-test.jpg
Gets you a good quality JPG but the output is a fraction of the letter
size that you started with. You can scale this in the GIMP and the
quality remains good. With some fiddling (maybe a lot of fiddling) with
the command line above I think I may be able to skip the scan step
altogether where the PDF to be modified is a downloaded file.
(Note: this command uses a lot of CPU time, in the range of 95%, and in
a couple instances where I had a lot of other things open the other apps
exited or this "convert" process segfaulted. Nothing broke however...)
For me the goal is to work on docs my way ( the Linux way) and the
WinDoze person I am interacting with doesn't ever have a clue anything
other than M$ went on which means no discussions about things in which
they have no knowledge or interest (i.e I'm no longer entertained with
justifying my use of Linux in response to their questions in defense of
their use of M$ apps... ;^P ).
