This template tag allows the generation of arbirary qr code pngs that
can be displayed, for example, in <img src="..."> html tags.
The template tag can be used as follows:
<img src="{% qrcodepng %}
Hello world
{% endqrcodepng %}">
This will produce a qrcode that encodes the
string "\n Hello World\n ". One can use the qrcode parameter
``stripwhitespace`` to strip the extra whitespace at the start and end of
the string:
{% qrcodepng stripwhitespace %}
All supported arguments:
- stripwhitespace: strip whitespace of the qrcode-contents
- border=[int]: Border of the qrcode in pixels (default: 1)
- box_size=[int]: Pixel size of the qr-code blocks (default: 5)
