VNS 104 Scaling Modes

Each window can be set to one of three scalings: unity, follow, or fill (see figure 20, below).

Follow: The aspect ratio of the source image is maintained: the entire source video is displayed in the available screen or window size.

Fill: The entire source image is scaled to fit the available window or display size. Aspect ratio is not maintained.

Unity: The source will be displayed at its native resolution, positioned at the center of the decoded window as follows:

Display viewing area resolution is less than the source resolution: A reduced size view of the image is displayed, anchored at the center of the image. No scroll bars are shown at the edges and panning of the image is not possible.

Display viewing area resolution is equal to the source resolution: The entire image is displayed at its native resolution.

Display viewing area resolution is greater than the source resolution: The complete image is displayed at the center of the display viewing area with a black border at the video edges as necessary.
