IOS7: stage.toDataURL and stage.toImage not working with SVG Images

[confile]

I created a stage with a jpg image and an svg image on top. Then I tried to export the stage. It works fine on desktop but not on IOS. I created a JSFiddle to demonstrate this problem http://jsfiddle.net/confile/p6Eey/

Here is the code:

<div id="container"></div>
    <script src="http://d3lp1msu2r81bx.cloudfront.net/kjs/js/lib/kinetic-v5.1.0.min.js"></script>

var stage = new Kinetic.Stage({
        container: 'container',
        width: 1000,
        height: 1000
});
var layer = new Kinetic.Layer();
stage.add(layer);

var bgImage = new Image();
bgImage.onload = function() {
    var bgimg = new Kinetic.Image({
        image: bgImage,
        width: 1000,
        height: 1000
    });

    layer.add(bgimg);
    layer.draw();

    var img=new Image();
    img.onload = function () {
        var image1 = new Kinetic.Image({
            image: img,
            x: 300,
            y: 300
        });
        layer.add(image1);
        layer.draw();

        image1.scale({
            x: 0.3,
            y: 0.3
        });   

        image1.rotate(45);        
        layer.draw();

        stage.toDataURL({
            mimeType: "image/jpeg",
            quality: 1.0,
            callback: function(image) {
                alert("toDataURL");
               // document.body.appendChild(image);
            }
        });

        stage.toImage({
            mimeType: "image/jpeg",
            quality: 1.0,
            callback: function(url) {
                alert("toImage");

            }
        });

    } 
    img.crossOrigin="anonymous";
    img.src = "https://dl.dropboxusercontent.com/u/47067729/sandwich2.svg";

};

bgImage.crossOrigin="anonymous";
bgImage.src =
    "https://dl.dropboxusercontent.com/u/47067729/Foto2.jpg";

It works on IOS only if you don't use SVG images.

@lavrton Convert image to png with canvas is not working because auf security concerns.

[lavrton]

Convert it on server side and use converted png on client or look there https://code.google.com/p/canvg/

@lavrton Why should canvg solve the security problem?

[lavrton]

I was not testing. But I guess it should work (library works as parser). https://code.google.com/p/canvg/#Potential_uses

I works only with Canvg https://code.google.com/p/canvg/ on Safari and ios.
