Gwt-query: get an Image from ImageData

I'm trying to accomplish this but I've got no clue about getting a GWT Image from a Canvas ImageData. I'm issuing this piece of code: 

ImageData canvasImageData = canvas.getContext2d().getImageData(0, 0, 500, 500);

My purpose is to get the Image somehow, any idea?

Thanks in advance!

To create an Image from your canvas you should use Canvas.toDataUrl(), which will give you the image data encoded as a string which can be used as the src attribute for an <img> tag.

Image canvasImage = new Image(canvas.toDataUrl());
