## 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](https://sourceforge.net/projects/bcmath-js) and
[pdf417-js](https://github.com/bkuzmic/pdf417-js).
### Browser
You can find a complete example at [examples/browser](examples/browser) and a running demo [here](https://pkoretic.github.io/pdf417-generator).
The usage is as simple as providing a canvas element and a text that should be used for barcode generation:
```
```
**HTML**
```
```
**JS**
```
var code = "HRVHUB30\nHRK\n" +
"000000000012355\n"+
"PETAR KORETIĆ\n"+
"PREVOJ DD\n"+
"10000 Zagreb\n"+
"pkoretic J.D.O.O\n"+
"PREVOJ DD\n"+
"10000 ZAGREB\n"+
"HR5041240000000000\n"+
"HR01\n"+
"7336-68949637625-00001\n"+
"COST\n"+
"Uplata za 1. mjesec\n";
var canvas = document.getElementById("barcode")
PDF417.draw(code, canvas)
```
### Node.js
You can find a complete example at [examples/node](examples/node).
The [node-canvas](https://github.com/Automattic/node-canvas) library is used for drawing.
Install the library:
```
npm install pdf417-generator
```
Use it as:
```
const Canvas = require("canvas")
const PDF417 = require("pdf417-generator")
const code =
`HRVHUB30

console.log(`})
`)
```
