Create standard barcodes with Python. No external modules needed (optional PIL support included).

Project description

Fork of pyBarcode project.

This library provides a simple way to create barcodes using only the Python standardlib. The barcodes where created as SVG objects.

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 viivakoodi 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 viivakoodi.

Provided Barcodes

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

Todo

  • Add documentation
  • Improve Python 3 support

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 io import BytesIO
>>> fp = BytesIO()
>>> 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.
