Python barcode decoding

[Robocop]

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!

The closest thing I've heard of is the bar code stuff in reportlab.
This post talks a little about it:

I appreciate the effort, but that looks to be for generation of
barcodes if i'm not mistaken. 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.

If you don't mind using a commercial Java lib, use
http://www.tasman.co.uk/bars/readme.html. 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.

The open source OCR software 'gocr' does also implement some 1D
barcode recognition. 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:

How precise are these images? 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 . Look in the
Daycos.Imageproc.Barcode module.
