Re: How to remove drawn elements on the canvas?

Followed your suggestion using front and drag/back-canvas. Works really nice.

If someone else is looking for this: you can dublicate a canvas just by:
desintationCanvas.getCtx().drawImage(sourceCanvas.getCanvasElement(), 0, 0);

Don't create an image from the source canvas to draw it on the destination, this will take too much time and resources!
