You'd probably be better off asking on sci.image.processing, where you
were posting in the first place. That said, this is a reasonable place
for the following point:

You are presumable after a database of images of characters. You could
synthesize one by rasterizing a number of fonts (automatically) and
then adding various kinds of noise or various distortions.

I have a program for generating rasterizaton from here:

http://linuxfromscratch.org/pipermai...ry/004748.html

look at links-2.1pre32-italic.patch.gz

You can run this patch on an empty directory, to extract the relavent
files.

To add distortions, you may wish to experiment with pnmscale,
pnmrotate, pgmnoise and pnmshear to add distortions. To be honest,
comp.unix.shell is also a good place for this kind of commandline
stuff, so I've cross posted there as well. Maybe some imagemagick
expert can weigh in on adding errors automatically.
