== rqr

* http://rubyforge.org/projects/rqr/

== DESCRIPTION:

A ruby library to create QR codes. Output: PS, JPEG, PNG, EPS, TIFF.

A QR code is a 2-dimensional "barcode" of a type popular in Japan.
It is intended for transferring chunks of data such as long URLs
using a camera (Eg. on a phone), together with decoding software.

There is more information at http://en.wikipedia.org/wiki/QR_Code
and at http://www.denso-wave.com/qrcode/index-e.html.


== SYNOPSIS:

require "rubygem"
require "rqr"

# Block is available from version 0.2.1
RQR::QRCode.create do |qr|
  qr.save("http://www.amazon.com", "path/to/qrcode.jpg")
end


# QRCode options (passed to RQR::QRCode.new())
# Use options with hash values:
#   :level        L:0, M:1(default), Q:2, H:3 
#     Determines how fault tolerant the code is.
#   :version      S:0(default), M:1, L:2
#   :auto_extend  true|false 
#     Auto extend the version if data is too large for selected version
#   :masking      masking pattern 0-7, -1(default auto)
#   :length       data length
#   :module_size  module size (pixel)
#   :eps_preview  true|false

# This sample creates an EPS with preview.
RQR::QRCode.create(:eps_preview => true, :auto_extend => false) do |qr|
	qr.save("http://www.ebay.com", "path/to/qrcode.eps")
end


# Old style (0.2.0, 0.1.1, 0.1.0)

qr.save("http://www.google.com", "path/to/qrcode.jpg")
