In Windows 8.0 you would set the ZoomFactor property on the ScrollViewer to scale its content.

In Windows 8.1 the ScrollViewer has a ChangeView() method that takes parameters for zoom factor as well as horizontal and vertical offsets and supports view change animations.

To get it to fill your screen you would compare the ActualWidth or ActualHeight properties of your ScrollViewer and its content and set the zoom factor to the result.
