Canvas.swf is a polyfill which adds HTML5 Canvas support to Internet Explorer 6-8. Canvas.swf is implemented in Flash, with wider support and faster execution than polyfills that use VML or Silverlight.
Copy canvas.swf and canvas.swf.js from the lib/ directory to your website, and simply
include the JavaScript file in your <head>:
<!--[if lt IE 9]>
<script type="text/javascript" src="path/to/canvas.swf.js"></script>
<![endif]-->
That's it! You are now able to use and script the element as though it were supported natively.
Canvas.swf is released under the MIT License. Based on extensive work by the FlashCanvas Project.
