In what way could it be incorrect?

Provided that you remember the size of the original image in pixels,
you can always provide a mapping from the bounding box of a rendered
graphic back to the original image by just multiplying coordinates by
(original size/scaled size)

I would have thought that this was obvious - or am I overlooking some
vital piece of information here?
