This library provides a simple way to create barcodes using only the Python standard lib. The barcodes are created as SVG objects.

Full documentation is published at http://python-barcode.rtfd.io/

Please report any bugs at https://github.com/WhyNotHugo/python-barcode/issues

• Works on Python 3.5 to 3.8
• No visualiser (just use your browser)
• Generate barcodes as SVG files.
• Generate barcodes as images (png, jpeg, etc). Requires Pillow.

The best way is to use pip: pip install python-barcode. Don't forget to add this to our app's dependencies.

If you'll be exporting to images (eg: not just SVG), you'll need additional optional dependencies, so run: pip install python-barcode[images].

• EAN-8
• EAN-13
• EAN-14
• UPC-A
• JAN
• ISBN-10
• ISBN-13
• ISSN
• Code 39
• Code 128
• PZN

PRs for other code formats are welcome!

Programmatic:

from barcode import EAN13
from barcode.writer import ImageWriter

# print to a file-like object:
rv = BytesIO()
EAN13(str(100000902922), writer=ImageWriter()).write(rv)

# or sure, to an actual file:
with open('somefile.jpeg', 'wb') as f:
    EAN13('100000011111', writer=ImageWriter()).write(f)

Interactive:

>>> import barcode
>>> barcode.PROVIDED_BARCODES
['code39', 'code128', 'ean', 'ean13', 'ean8', 'gs1', 'gtin',
 'isbn', 'isbn10', 'isbn13', 'issn', 'jan', 'pzn', 'upc', 'upca']
>>> EAN = barcode.get_barcode_class('ean13')
>>> EAN
<class 'barcode.ean.EuropeanArticleNumber13'>
>>> ean = EAN('5901234123457')
>>> ean
<barcode.ean.EuropeanArticleNumber13 object at 0x00BE98F0>
>>> fullname = ean.save('ean13_barcode')
>>> fullname
'ean13_barcode.svg'
# Example with PNG
>>> from barcode.writer import ImageWriter
>>> ean = EAN('5901234123457', writer=ImageWriter())
>>> fullname = ean.save('ean13_barcode')
'ean13_barcode.png'
# New in v0.4.2
>>> from io import BytesIO
>>> fp = BytesIO()
>>> ean.write(fp)
# or
>>> f = open('/my/new/file', 'wb')
>>> ean.write(f) # Pillow (ImageWriter) produces RAW format here
>>> from barcode import generate
>>> name = generate('EAN13', '5901234123457', output='barcode_svg')
>>> name
'barcode_svg.svg'
# with file like object
>>> fp = BytesIO()
>>> generate('EAN13', '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:

`$ python-barcode create "123456789000" outfile -b ean --text "text to appear under barcode" `
New barcode saved as outfile.svg.

# The following will not work if Pillow is not installed (Pillow is required for exporting to images instead of SVG).
$ python-barcode create -t png "My Text" outfile
New barcode saved as outfile.png.

Try `python-barcode -h` for help.

• Added basic support for multiline text.
• Dropped lots of older compat-only code and other cleanups.
• Fixed a bug in the API when combining certain barcodes and writers.
• Published documentation again and updated all project references.
• Fix python_barcode.get mixups between options as writer_options. Previously, some writer/barcode combinations worked fine, while others failed. Now all work consistently.
• The cli tool has been fixed and should now work as expected again.

• Added support for GS1-128.

• Officially support Python 3.7
• Refer to Pillow in the docs, rather than PIL.

• Removed buggy Barcode.raw attribute.
• Various CLI errors ironed out.
• Make the default value for writer_options` consistent across writers.

• Fix pushing of releases to GitHub.

• Fix crashes when attempting to use the CLI app.
• Properly include version numbers in SVG comments.

• Improve README rendering, and point to this fork's location (the outdated README on PyPI was causing some confusion).

• First release under the name python-barcode.

This project is a fork of pyBarcode, which, apparently, is no longer maintained. v0.8.0 is our first release, and is the latest master from that parent project.

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

• 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.

• 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.

• 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".

• Fixed bug in new write method (related to PIL) and updated docs.

• Added write method to support file like objects as target.

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

• 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).

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

• Support for rendering barcodes as images is implemented. PIL is required to use it.

• Compression for SVG output now works.

• 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).

• API of render changed. Now render takes keyword arguments instead of a dict.

• More tests added.

• First release.
