I’m trying to draw the second half of the screen into the first using bitmap data. here is my code:

```auto

var screenData:BitmapData = new BitmapData(275,400);
screenData.draw(root,null,null,null,new Rectangle(275,0,275,400));

var screenBitmap:Bitmap = new Bitmap(screenData);

addChild(screenBitmap);

```

this image explains my problem:

1. this is what the stage looks like
2. this is what I want the stage to look like after the code executes
3. this is what actually happens

I have a suspicion that it might involve using a matrix, but they’re pretty foreign to me…  
thanks for any help!
