How can I make a SurfaceView larger than the screen?

Question

I would like to effectively make a simple digital zoom for the camera preview, so I thought I would simply resize my SurfaceView to be larger than the screen. Other questio

Here's my TouchSurfaceView's onMeasure that performs zoom:

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
    {
        int width = MeasureSpec.getSize(widthMeasureSpec);
        int height = MeasureSpec.getSize(heightMeasureSpec);
        setMeasuredDimension((int) (width * scaleFactor), (int) (height * scaleFactor));
    }

This properly zooms in and out depending on scaleFactor.

I haven't tested this with camera, but it works properly with MediaPlayer (behaving as VideoView).
