Octopress QR-Code in sidebar

This is a simple aside for Octopress that uses the Google Code-API to automatic generate and dislay the QR Code-image of the actually visible page or post in the sidebar.

Preview

Check my blog for a preview in the sidebar and background-information (in german).

Setup

First of all you need to copy the file:

  • qrcode.html into source/_includes/custom/asides/

After that you need to update these file:

_config.yml

  • add 'custom/asides/qrcode.html' to default_asides

That's it. More options:

Option Change color

To change the color of the QR-Code-image substitute in file qrcode.html in the part

img src="http://chart.apis.google.com/chart?chs=100x100&cht=qr&chld=|0
&chco=0000FF&chl=...

&chco=0000FF

e.g. to

  • red: &chco=FF0000
  • green: &chco=00FF00
    or any other color marked in hexcode (without the #).

Option Change size

To change the size of the QR-Code-image substitute in file qrcode.html in the part

img src="http://chart.apis.google.com/chart?chs=100x100&cht=qr&chld=|0
&chco=0000FF&chl=...

100x100

in the size you want. It size is given in pixels (pt). Height and width must be the same, eg. 150x150, 200x200 etc.
