Trying to capture stage area using BitmapData

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);

Can't you just call bmd.draw(stage)?

  var stage_snapshot:BitmapData = new BitmapData(600, 120);

  var myRectangle:Rectangle = new Rectangle(0, 0, 600, 120);


  var myMatrix:Matrix = new Matrix();

  var translateMatrix:Matrix = new Matrix();

  translateMatrix.translate(-100, -225);

  myMatrix.concat(translateMatrix);

  stage_snapshot.draw(stage,myMatrix,null,null,myRectangle);

  var encoded_jpg:JPGEncoder = new JPGEncoder(100);

  var jpg_binary:ByteArray = new ByteArray();

  jpg_binary = encoded_jpg.encode(stage_snapshot);
