How to get width and height object in library in Actionscript 3?

Answer 1

To get width and height of a library asset during runtime, you need to create an instance of it, add it to stage, and then query getRect() or getBounds() of the created instance. If you don’t need that instance right now, just remove it from stage.

var temp:DisplayObject=new YourLibraryAsset();
stage.addChild(temp); 
var r:Rectangle=temp.getRect(stage);
stage.removeChild(temp);

This does not work if the current class does not have an access to stage.
