python-barcode

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

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

Requirements

Setuptools/distribute for installation.
Python 3.5 or above
Program to open SVG objects (your browser should do it)
Optional: Pillow to render barcodes as images (PNG, JPG, ...)

Installation

The best way is to use pip: pip install python-barcode.

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

Provided Barcodes

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

Usage

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 "My Text" outfile
New barcode saved as outfile.svg.
$ python-barcode create -t png "My Text" outfile
New barcode saved as outfile.png.

Try `python-barcode -h` for help.

Changelog

v0.9.1

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

v0.9.0

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

v0.8.3

Fix pushing of releases to GitHub.

v0.8.2

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

v0.8.1

Improve README rendering, and point to this fork's location (the outdated README on PyPI was causing some confusion).

v0.8.0

First release under the name python-barcode.

Previous Changelog

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.

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.
