Generating QR codes

QR codes are two-dimensional bar codes that can be scanned with a phone. They provide a simple way of going to a site without having to type in a web address, and so are often found on business cards and in adverts.

To generate a QR code for a page, go into edit mode on the page for which you want a QR code, click the Panels button on the toolbar, and click the QR code button, whose icon is shown in figure 1.

The QR code panel will then open in a new browser tab, displaying a QR code for the page. The QR code is a normal image, and can be saved to your computer by dragging it off the browser window. You can customise the QR code by choosing a size and a level of redundancy. Higher levels of redundancy make it more likely that a corrupted QR code will be read correctly, but increases the number of pixels in the code.
