title: how to call methods of excanvas?
body: <p>I need a little help from you. I have created a canvas image using <a href="http://excanvas.sourceforge.net/" rel="nofollow">excanvas.js</a> and it was rendered properly. Now i want to use that same canvas to draw another image but before that i need to clear that same canvas otherwise images will be overlapped over each other.
  Can anyone please explain how can i call <a href="http://excanvas.sourceforge.net/" rel="nofollow">fillRect()</a> or any another method from <a href="http://excanvas.sourceforge.net/" rel="nofollow">excanvas.js</a> for the same canvas element ?? I am using IE 8 as browser. </p>
