Я делал так... Качество норм...

	private function loadComplete(e:Event):void
		{
			var loader:Loader = e.target.loader as Loader;
			loader.removeEventListener(Event.COMPLETE, loadComplete);
 
			var bm:Bitmap = new Bitmap((loader.content as Bitmap).bitmapData,"auto",true);

					bm.scaleY = bm.scaleX;
				}
			}

					bm.scaleX = bm.scaleY;
				}
			}
			var bd2:BitmapData = new BitmapData(bm.width, bm.height, true);
			bd2.draw(bm, bm.transform.matrix);
			bm = null;
			encode(bd2);
