I want to resize jpeg images (in order to create thumbnail images for a
webpage) from a bash script and know that I can use 'convert' from the
imagemagick package to achieve this. This will be run on a (headless,
no X) lenny/armel NSLU2 "slug".
However, aptitude says that to install imagemagick requires 78 new
packages, including x11-common, various gtk and font libraries - which
will be irrelevant on the NSLU2. Using the without-recommends switch in
aptitude reduces the package count to 63 and choosing the
'graphicsmagick-imagemagick-compat' package rather than imagemagick
brings it down to "only" 52 packages. This still seems quite a lot and
includes lots of font stuff and x11-common when all I want is the
'convert' command.
Does anyone know of a simpler, slimmer alternative for resizing jpegs
from the command line please?

GIMP ships with a second binary called gimp-console. This binary is a
console-only version and behaves as if gimp was called with the
--no-interface command-line option.

I think you refer to gimp-console. Does it solve the OPs problem of
Imagemagick being too heavy? I suspect that installing Gimp will also
pull in several X and GTK+ based dependencies which offer little value
on a Slug...
As for other options, I cannot think of any myself. However, I suspect
that while Imagemagick convert will stress your SLUG a little, it
might still do the job for you as long as you don't run much else on
the Slug...

Thank you for the suggestion Paul, but you are right Kumar: Gimp wanted to
pull in nearly 70 packages totalling 107MB.

As it happens I have gone ahead and installed imagemagick and it works
fine. I just wanted to avoid installing what seems like unnecessary
packages. They won't actually be doing anything and I am not short of
disk space, so really it does not matter at all I suppose.
The slug is kept busy running motion (movement detecting with a webcam)
and saving the resulting images. Using convert from imagemagick to
reduce these images for viewing on a webpage will only add a bit more
stress ;-)

It all depends on your needs.
djpeg (from libjpeg-progs) Currently the scale factor must be 1/1, 1/2, 1/4, or 1/8.
