That's where the power of unix/Linux helps out. The gerbv stuff is
tested nightly using scripts which compare newly rendered Gerber files
against pre-existing "golden" ones. Differences between the
newly rendered image and the golden one are automatically flagged
using the script, so no human intervention is required.
Here's the script:
http://gerbv.cvs.sourceforge.net/gerbv/gerbv/test/run_tests.sh?revision=1.5&view=markup
Maybe this will give you some ideas about how to use gerbv/ImageMagick
to perform your task.
Cheers,
Stuart
