PDF417 HUB3 Barcode Generator

This library provides you with the ability to generate PDF417 HUB3 Barcodes in browser or Node.js apps. The final barcode is drawn into a canvas element and can be used for many different use cases. The code is based on the bcmath-js and pdf417-js.

Browser

You can find a complete example at examples/browser and a running demo here.

The usage is as simple as providing a canvas element and a text that should be used for barcode generation:

<script src="https://cdn.rawgit.com/qaap/pdf417-generator/master/lib/libbcmath.js" type="text/javascript"></script>
<script src="https://cdn.rawgit.com/qaap/pdf417-generator/master/lib/bcmath.js" type="text/javascript"></script>
