In a related question, is there any guarantee that when we draw an image

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.
Seems easier to take care of this by allowing extraction of metadata (some
W3C WG is working on this I think) and maybe a way to put it back in...
