====== Elaphe ====== .. note:: **Thomas Grainger integrated Python3 support in his fork, see https://pypi.python.org/pypi/elaphe3** 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.
