You don't.  The canvas is just a bitmap; it has no attached metadata.

This could be changed, but various things would need to be defined about 
what happens when multiple images are drawn in, when images are drawn on 
top of other things in the canvas, when stuff is drawn on top of images 
in the canvas, etc.
