So, when loading a swf file the Event.INIT event is dispatched when the first frame of the swf file has been loaded. Does this work with bitmaps ? can you access, say, the width and height of a bitmap in an Event.INIT event, or is it just the same if you wait for the Event.COMPLETE event ?
No Event.INIT does not fire for Bitmaps since there is no code execution with them. However, in AS3 the Event.COMPLETE is always fired after the Event.INIT so you can use Event.COMPLETE for everything and not worry much
