icojs

A JavaScript library to use ICO.

Work on both Node.js and Browser.

var fs = require('fs');
var ICO = require('icojs');

var arrayBuffer = new Uint8Array(fs.readFileSync('favicon.ico')).buffer;
ICO.parse(arrayBuffer).then(images => {
  // do something
});

Install

Node.js:

npm install icojs

Browser:

bower install icojs

And add to HTML:

<script type="text/javascript" src="/path/to/ico.js"></script>

To fully use this library, browsers must support JavaScript typed arrays, Canvas API and Promise.

Chrome, Edge 12, Firefox and Safari 9 support these functions.
