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 .

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'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.

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

The closest thing I've heard of is the bar code stuff in reportlab.

Python barcode decoding
Does anyone know of any decent (open source or commercial) python barcode recognition tools or libraries. I need to read barcodes from pdfs or images, so it will involve some OCR algorithm. I also only need to read the code 93 symbology, so it doesn't have to be very fancy. The most important thing to me is that it outputs in some python friendly way, or ideally that it is written in python. Any tips would be great! -- http://mail.python.org/mailman/listinfo/python-list
