rQRCode-image is a library for encoding QR Codes, and render images using RMagick in Ruby. It has a simple interface with all the standard qrcode options. It is a fork of whomwah(Duncan Robertson's rqrcode gem).
Let's clear up some rQRCode-image stuff.
- rQRCode-image is NOT a standalone library It requires RMagick and thus ImageMagick.
- It is an encoding library. You can't decode QR codes with it.
- The interface is simple and assumes you just want to encode a string into a QR code, then render an image of the QR Code
- QR code is trademarked by Denso Wave inc

To run the tests:
$ rake
You have installed the gem already, yeah?
require 'rubygems'
require 'rqrcode-image'
qr = RQRCodeImage::QRCode.new( 'my string to generate', :size => 4, :level => :h )
puts qr.to_image
## Simple QRCode generation to template (RubyOnRails)
```erb
# Controller
@qr = RQRCodeImage::QRCode.new( 'my string to generate', :size => 4, :level => :h )
