pyBarcode
This library provides a simple way to create barcodes using only the
Python standardlib. The barcodes where created as SVG objects.
Report bugs at https://bitbucket.org/whitie/python-barcode/issues/

Requirements

Setuptools/distribute for installation (new in version 0.7beta4)
Python 2.6 or above (including Python 3.x)
On Python 2.6, 3.0, 3.1: argparse (for the commandline script)
Program to open SVG objects (your browser should do it)
Optional: PIL to render barcodes as images (PNG, JPG, …)

Installation
Make sure you have setuptools/distribute installed.
Unpack the downloaded file, cd into the pyBarcode directory and run
python setup.py install. Or just copy the barcode dir somewhere in
your PYTHONPATH.
The best way is to use pip: pip install pyBarcode.

Provided Barcodes
EAN-8, EAN-13, EAN-14, UPC-A, JAN, ISBN-10, ISBN-13, ISSN, Code 39, Code 128, PZN

Todo

Add documentation
Add more codes
Improve Python 3 support
Add simple GUI

Usage
Interactive:
>>> import barcode
>>> barcode.PROVIDED_BARCODES
[u'code39', u'code128', u'ean', u'ean13', u'ean8', u'gs1', u'gtin',
u'isbn', u'isbn10', u'isbn13', u'issn', u'jan', u'pzn', u'upc', u'upca']
>>> EAN = barcode.get_barcode_class('ean13')
>>> EAN
<class 'barcode.ean.EuropeanArticleNumber13'>
>>> ean = EAN(u'5901234123457')
>>> ean
<barcode.ean.EuropeanArticleNumber13 object at 0x00BE98F0>
>>> fullname = ean.save('ean13_barcode')
>>> fullname
u'ean13_barcode.svg'
# Example with PNG
>>> from barcode.writer import ImageWriter
>>> ean = EAN(u'5901234123457', writer=ImageWriter())
>>> fullname = ean.save('ean13_barcode')
u'ean13_barcode.png'
# New in v0.4.2
>>> from StringIO import StringIO
>>> fp = StringIO()
>>> ean.write(fp)
# or
>>> f = open('/my/new/file', 'wb')
>>> ean.write(f) # PIL (ImageWriter) produces RAW format here
# New in v0.5.0
>>> from barcode import generate
>>> name = generate('EAN13', u'5901234123457', output='barcode_svg')
>>> name
u'barcode_svg.svg'
# with file like object
>>> fp = StringIO()
>>> generate('EAN13', u'5901234123457', writer=ImageWriter(), output=fp)
>>>
Now open ean13_barcode.[svg|png] in a graphic app or simply in your browser
and see the created barcode. That’s it.
Commandline:
$ pybarcode{2,3} create "My Text" outfile
New barcode saved as outfile.svg.
$ pybarcode{2,3} create -t png "My Text" outfile
New barcode saved as outfile.png.

Try `pybarcode -h` for help.

Changelog

v0.8:
Code 128 added. Data for charsets and bars moved to subpackage
barcode.charsets. Merged in some improvements.

v0.7:
Fixed some issues with fontsize and fontalignment.
Added Python 3 support. It’s not well tested yet, but the tests
run without errors with Python 3.3. Commandline script added.

v0.6:
Changed save and write methods to take the options as a dict
not as keyword arguments (fix this in your code). Added option
to left align the text under the barcode. Fixed bug with EAN13
generation.

v0.5.0:
Added new generate function to do all generation in one step.
Moved writer from a subpackage to a module (this breaks some
existing code). UPC is now rendered as real UPC, not as EAN13
with the leading “0”.

v0.4.3:
Fixed bug in new write method (related to PIL) and updated docs.

v0.4.2:
Added write method to support file like objects as target.

v0.4.1:
Bugfix release. Removed redundancy in input validation.
EAN8 was broken. It now works as expected.

v0.4:
Removed **options from writers __init__ method. These options never
had effect. They were always overwritten by default_options.
New config option available: text_distance (the distance between
barcode and text).

v0.4b2:
Basic documentation included. The barcode object now has a new
attribute called raw to have the rendered output without saving
to disk.

v0.4b1:
Support for rendering barcodes as images is implemented.
PIL is required to use it.

v0.3:
Compression for SVG output now works.

v0.3b1:
Writer API has changed for simple adding new (own) writers.
SVG output is now generated with xml.dom module instead of
stringformatting (makes it more robust).

v0.2.1:
API of render changed. Now render takes keyword arguments
instead of a dict.

v0.2:
More tests added.

v0.1:
First release.
