Download html2canvas image to desktop
<p>I found this <a href="https://jsfiddle.net/8ypxW/3/" rel="noreferrer">https://jsfiddle.net/8ypxW/3/</a> and I would like to know how to download image to desktop. I only see save png but no download if it's possible can you give me the script? </p>

<pre><code>     $(function() { 
     $("#btnSave").click(function() { 
       html2canvas($("#widget"), {
        onrendered: function(canvas) {
            theCanvas = canvas;
            document.body.appendChild(canvas);

            // Convert and download as image 
            Canvas2Image.saveAsPNG(canvas); 
            $("#img-out").append(canvas);
            // Clean up 
            //document.body.removeChild(canvas);
        }
      });
    });
}); 
</code></pre>
