======
Elaphe
======

Elaphe is a python binding of Barcode Writer In Pure PostScript
(http://www.terryburton.co.uk/barcodewriter/).
It generates barcode symbol as PostScript code fragment using
BWIPP. The generated code is then embedded in encapsulated
PostScript image which can be handled by PIL.

Prerequisites
==============

* Python 2.7 or later (functional decorators, ternary operator, and
generator expressions are used).

.. note::

Except ``setup.py test``, code may still work on 2.5-2.6.

* If you want to render barcode into bitmap image, EpsImagePlugin of
Python Imaging Library (http://www.pythonware.com/products/pil) or
Pillow is required. Note that EpsImagePlugin requires Ghostscript is
correctly installed.

Simple Usage
=============

The following example::

>>> from elaphe import barcode
>>> barcode('qrcode',
... 'Hello Barcode Writer In Pure PostScript.',
... options=dict(version=9, eclevel='M'),
... margin=10, data_mode='8bits')) # Generates PIL.EpsImageFile instance

>>> _.show() # Show rendered bitmap

will invoke some viewer which shows a QRcode symbol with 10px margin.

Remember, barcode() returns PIL image object.
