3-5. Image Size (Projector-to-Screen Distance)

Adjust the size of the projected image using the zoom control buttons. The projected image size values, as they relate
to the distance-to-screen value, are shown for focal lengths of f=25mm and f=45mm. Also shown is the maximum
image height shift value that can vary depending on the focal length and the distance-to-screen. Figure 3.4.
