Here's a guess: I think of a "drawable" as an area on the screen. I
think you're pulling the image from the wrong object.
It's hard to do better than guessing because I can't tell exactly what
type the "$area" variable is, and what the "window" member is. Please
post more detail. If possible, post a working, but concise, example of
the problem. This will make more info available *and* people will be
able to test it.
