# Google Charts QR Code wrapper [![Build Status](http://travis-ci.org/jhsu/google-qr.png)](http://travis-ci.org/jhsu/google-qr)

Generate url strings and HTML img tags for QR codes from [Google's QR code infographics API](https://developers.google.com/chart/infographics/docs/qr_codes)

## Install

    gem install google-qr

## Usage

    require 'google-qr'

    # data and size are both required. size defaults to "100x100".

    # The default margin is 4 and default error correction level is 'L'

    chart = GoogleQR.new(:data => "SomeDataToQRify", :size => "100x100", :margin => 4, :error_correction => "L")

    chart.to_s

    #=> "https://chart.googleapis.com/chart?cht=qr&chl=SomeDataToQRify&chs=100x100"

    chart.render

    #=> ""

    

You can also use the to_qr and to_qr_image methods on String objects.

    "ExampleQRData".to_qr

    #=> https://chart.googleapis.com/chart?cht=qr&chl=ExampleQRData&chs=100x100

    "ExampleQRData".to_qr_image

    

    "ExampleQRData".to_qr(:size => "200x200")

    #=> https://chart.googleapis.com/chart?cht=qr&chl=ExampleQRData&chs=200x200

    

## Testing

To run the tests just run the rake command from the root of the gem.
