Human Readable Quick Response Created by Valentin Heun

If you want to embbed HRQR Codes in to your own webpage, you have two possibilities:

1. Go to hrqr.org enter your message and copy past the generated iframe.

2. Do the following steps:

Add the two scripts "HRQRLetterdatabase.js" and "HRQR.js" to your webpage. If you want to stay conform with the main project, you can include the letter database directly from this project.

Example:

 <script src="https://raw.githubusercontent.com/hrqr/hrqr.github.io/master/HRQRLetterdatabase.js"></script>
 <script src="HRQR.js"></script> 

Define a div tag where the tag should be drawn in to.

Example:

  <div id="svgDiv"></div>

Then call the javascript function:

  drawHRQR("svgDiv","message");

• "svgDiv" should be the ID of your div tag.
• "message" should be the message you want to encode in HRQR.

You can change some properties of the library by defining values in an object called: globalStates

Example:

globalStates.color = "0000FF";

The following properties can be changed:

The Width and Height allways should be identical:

• .width
• .height

This defines the left and top white space between the div boarder and the tag.

• .left
• .top

This thefines the color of the tag.

• .color
