I did a python barcode decoder for Code39 a few years ago: http://www.wiredfool.com/2006/07/04/barcode-recognition/ http://www.wiredfool.com/2006/07/04/barcode-recognition/ . Alternate symbologies aren't that hard to do since the decoding instructions are floating about. And helpfully enough, my code needed a pretty good crop on the barcode, and that's what this article gives you.
