I'ts not exactly cheap, but it works very well, and support is good. The only suggestion I can give you is: stay away from mixed OCR/Barcode recognition software; usually they are much slower.

In my experience it does this better then recognizing the text: http://jocr.sourceforge.net/ I know about only one open source library for the DataMatrix 2D code, but this certain library is excellent: http://www.libdmtx.org/ Wolfgang Draxinger -- E-Mail address works, Jabber: [EMAIL PROTECTED], ICQ: 134682867 -- http://mail.python.org/mailman/listinfo/python-list

I mean, are they computer-generated, or scanned in from other material? If they're nice and crisp, I wrote a simple and pretty quick decoder at http://pypi.python.org/pypi/Daycos/1.0 .

What i'm looking for is a barcode DECODER, not an ENCODER (i'm currently using the purepostscript barcode script for generation, very slick stuff), so i'm looking for something along the lines of some barcode specific OCR libraries. -- http://mail.python.org/mailman/listinfo/python-list
