Fast, robust, and less incomplete cffi-based bindings for libqrencode (Py2, Py3, and PyPy)
Project description
Fast, robust, and slightly less incomplete cffi-based Python bindings for libqrencode (http://fukuchi.org/works/qrencode/index.en.html).
Python 2, Python 3, and PyPy compatible!
Installing
$ pip install libqrencode-cffi
Examples
>>> import libqrencode as qr >>> qrc = qr.QRCode("Hello, world!") # The raw QR code can be accessed, where each item is a bitfield containing # information about that portion of the code (see DATA_* constants). >>> qrc.get_raw_data() [193, 193, 193, 193, ... 3, 2, 2, 3, 3] # If PIL is installed, a PIL image of the QR code can be created: >>> qrc.get_im(border=3) <PIL.Image.Image image mode=L size=81x81 at ...> # And if lxml.etree / xml.etree is available, an SVG can be generated: >>> qrc.get_svg_etree() <Element g at ...> >>> qrc.get_svg_string() '<g><rect fill="white" height="21" width="21" x="0" y="0"/>...<rect fill="black" height="1" width="1" x="20" y="19"/></g>'
