Generates various barcodes using barcode.ps and pillow.
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.
Python 2.7 or later (functional decorators, ternary operator, and generator expressions are used).
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.
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.
