Answer 1

Finally used this solution to copy part of the stage

(I copied everything that is on stage from (360, 20) and after)

var bitmapdata:BitmapData = new BitmapData(stage.stageWidth, stage.stageHeight);

bitmapdata.draw(stage);

var bitmapDataA: BitmapData = new BitmapData(300, 250);

bitmapDataA.copyPixels(bitmapdata, new Rectangle(360, 20, 320, 240), new Point(0, 0));

var myEncoder:JPGEncoder = new JPGEncoder(90);

var byteArray:ByteArray = myEncoder.encode(bitmapDataA);
