I've an app that takes a picture. It creates 2 subset bitmaps, processes these bitmaps with a distortion, then places the subsets over the original as overlays. Is there a way to save all three bitmaps as one (as it appears on the phone's screen)? I'd like to save what the user sees on the screen as a fourth bitmap on the sdcard? I've a feeling I've done this wrong.

Thanks

```
@Override
    public void onDraw(Canvas canvas){
        super.onDraw(canvas);

        Log.e(TAG, "******about to draw bgr ");
        canvas.drawBitmap(bgr, 0, 0, null);

        if (isLocked == true && bothCirclesInPlace == true){
            if(overLay != null)
             canvas.drawBitmap(overLay, centreX-radius, centreY-radius, null);
            if(overLay2 != null)
             canvas.drawBitmap(overLay2, centreA-radius, centreB-radius, null);
        }
