Package: viivakoodi
Viivakoodi(barcode in Suomi)
is the fork ofpyBarcodeproject.This library provides a simple way to create barcodes using only the
Python standardlib. The barcodes where created as SVG objects.Report bugs athttps://github.com/kxepal/viivakoodi/issues/RequirementsSetuptools/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, …)InstallationMake sure you have setuptools/distribute installed.Unpack the downloaded file, cd into the viivakoodi directory and runpython setup.py install. Or just copy the barcode dir somewhere in
your PYTHONPATH.The best way is to use pip:pip install viivakoodi.Provided BarcodesEAN-8, EAN-13, UPC-A, JAN, ISBN-10, ISBN-13, ISSN, Code 39, Code 128, PZNTodoAdd documentationAdd more codesImprove Python 3 supportAdd simple GUIUsageInteractive:>>> import barcode

>>> 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.Changelogv0.8:Code 128 added. Data for charsets and bars moved to subpackage
barcode.charsets.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 calledrawto 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.
