If the image is simple like an ellipse, you can save ellipse parameters in variables or in an array, and just draw the same ellipse on the second canvas.
To copy some random image from one canvas to another you need to save it, load into a sprite and then paste the sprite on canvas. It's a lot of work..
Another option is to make the Canvas1 object global. Then when you switch to another layout, Canvas1 will not be destroyed and you could paste it directly onto Canvas2.
