jQuery ui draggable: saving to canvas

I have a product image (prodimage) and with a button click I can add it to a canvas. For now both the product image and the canvas are on the same html page.

function CanvasIt() {
var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
var img = document.getElementById("prodimage");
ctx.drawImage(img, 10, 10);
};

Open in new window


I also have some draggable images and after the are positioned over the prodimage I would like to add them to the same canvas.

<script type="text/javascript">
$(function() {
	
	$("#graphicCount11").draggable({ 
		containment: "#product-image-wrapper", 
		scroll: false,
		stop: function(event, ui) {
		   };
	 });
</script>

Open in new window


Anyone have an idea of how this can be done?

            ctx.drawImage(img, 10, 10);
        }
	 });
});

function CanvasIt() {
    var c = document.getElementById("myCanvas");
    var ctx = c.getContext("2d");
    var img = document.getElementById("prodimage");
    ctx.drawImage(img, 10, 10);
