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.
