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 <PIL.EpsImagePlugin.EpsImageFile ... at ...> >>> _.show() # Show rendered bitmap
will invoke some viewer which shows a QRcode symbol with 10px margin.
Remember, barcode() returns PIL image object.
