[HOW TO] Create QR Codes in Xubuntu 12.04

A QR code is a type of barcode that consists of black modules arranged in a square pattern on a white background. It's a compact way of providing information and a smartphone can be used for reading that information.

Qreator is an application that can create QR codes for URL, Text, Location and Wifi Settings. The QR code can be saved as a PNG image file or copied to the clipboard.

Qreator running on Xubuntu 12.04

Install

Open a terminal window and run:

sudo apt-get install qreator -y

OR

Click here to install Qreator

Usage

Qreator is available at Applications Menu > Accessories > Qreator.

It can also be accessed with the command /opt/extras.ubuntu.com/qreator/bin/qreator, supplying it one of the following options:

Usage: qreator [options]

Options:
  --version       show program's version number and exit
  -h, --help      show this help message and exit
  -v, --verbose   Show debug messages (-vv debugs qreator_lib also)
  -u, --url       Create a QR code for a URL
  -t, --text      Create a QR code from text
  -l, --location  Create a QR code for a location
  -w, --wifi      Create a QR code for WiFi settings

Tip: this website can be used to read information from QR code images (and create codes as well).

Here's a nice video (from ubuntued.info) that exemplifies Qreator usage:
