Description: libqrencode: fast QR code encoding for Python
        =============================================
        
        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
        
        
        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>'
        
        
        Constants

        * ``ECLEVEL_H`` (30%)
        
        
        Raw data bitmasks:
        
        * ``DATA_BW`` (1=black/0=white)
        * ``DATA_DATA_AND_ECC`` (data and ecc code area)
