Hi I’m generating quite a complex BitmapData object and drawing a lot of symbols into it using copyPixels. Now, there’s always a delay from when I start drawing until it’s actually rendered and appears on the screen.

So, the question is, is it possible to add some kind of listener for when it’s all done? I can’t seem to find a listener in the Flash API.
