SVG to IMG

vad data = var new XMLSerializer().serializeToString(theSvgDomNode);

var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");

var DOMURL = self.URL || self.webkitURL || self;
var img = new Image();
var svg = new Blob([data], {type: "image/svg+xml;charset=utf-8"});
var url = DOMURL.createObjectURL(svg);
img.onload = function() {
    ctx.drawImage(img, 0, 0);
    DOMURL.revokeObjectURL(url);
};
img.src = url;

The first line should be:

var data = new XMLSerializer().serializeToString(document.getElementById('svg'));
