maximum size of a sprite in as3?

Question

Is there an upper bound to the size of a sprite in as3 / flash 10?

I know bitmapData has limitations...

Answer 1

it seems, that xScale and yScale may not exceed 0x8000 ...

size itself also seems to be bound ... i found a limit 0x6666660 ...

here the code:

package {
    import flash.display.*;
    public class Main extends Sprite {
        public function Main():void {   
            var size:Number = 1;

            var s:Shape = new Shape();
            s.graphics.beginFill(0xFF00FF);
            s.graphics.drawRect(0, 0, size, size);

            var old:Number = 0;
            while (s.width > old) {
                old = s.scaleX; 
                s.scaleX *= 1.1;
            }
            trace(s.width.toString(16));

            size = 1;
            s.scaleX = 1;
            while (true) {
                size *= 2;
                s.graphics.clear();
                s.graphics.drawRect(0, 0, size, size);
                if (s.width < 0) break;
            }
            var min:Number = size / 2;
            var max:Number = size;

            while (true) {
                size = (min + max) / 2;
                s.graphics.clear();
                s.graphics.drawRect(0, 0, size, size);
                if (s.width < 0) max = size;
                else 
                    if (max - min < 1) break;
                    else min = size;

            }
            trace(s.width.toString(16));
        }
    }   
}

didn't find any documentation about it ... so you may even get other results on your machine ...
