should be able to take care of that with imagemagick and cropping easily enough.
http://www.imagemagick.org/Usage/crop/
Bash or python or whatever for the scripting part of it.
You can also do gimp scripts, or there's even a plugin for scripting gimp with python, but that is probably overkill and would take too long to figure out for something as simple as you're doing.

You could modify some of my bbips scripts to do that....
here is the url for the "crop" section dealing with imagemagick
http://www.imagemagick.org/Usage/crop/#crop
Here is a quick bash script I put together...... didn't test it, but it should do the trick i think.... you will need to modify the settings to suit your needs.

#!/bin/bash
# by Crouse 09-02-2008
# Save and run file in directory of images to be changed.
# Crops .png files to size and then changes them to .eps files.
# Check for required programs
if [[ -z $( type -p convert ) ]]; then echo -e "ImageMagick -- NOT INSTALLED !";exit ;fi
if [[ -z $( type -p sed ) ]]; then echo -e "sed -- NOT INSTALLED !";exit ;fi
# Set IFS to correct parameter
export IFS=$'\n';
# Use Imagemagick to crop images
for i in $(find . -maxdepth 1 -type f -iname "*.png");
# Change 32x32 to reflect size of image wanted, and 0+0 is offset if needed.
do
convert ${i} -gravity Center -crop 32x32+0+0 +repage ${i}
done
# Change extentions from .png to .eps
echo "Converting from .png to .eps"
match=".png";
replacewith=".eps";
for i in $( find -iname ".png" );
do
src=$i
tgt=$(echo $i | sed -e "s/$match/$replacewith/")
echo renaming $src to $tgt
mv $src $tgt
done

same but converts the filename at the same time, also saves the original just in case the settings are wrong. (also doesn't depend on sed anymore only coreutils which is a dependency of imagemagick.)

Try removing the colon after the ${i} in this line
| Code: | | convert ${i}: -gravity Center -crop 32x32+0+0 +repage $(dirname ${i})/$(basename ${i} .png).eps |
so that it's | Code: | | convert ${i} -gravity Center -crop 32x32+0+0 +repage $(dirname ${i})/$(basename ${i} .png).eps |
I think it snuck in - at least that got rid of the problem here.
regards,
rumbarg
