Auto-Zoom/Pan & Scan
These affect the scaling of the live image.
Auto
-
Zoom – this switches to an image scaling function, where
resizing the window automatically scales the whole of the
video image to fit within the window. The aspect ratio of
the image adheres to the chosen shape of the window and
may therefore be distorted vertically or horizontally to
achieve "squashed" or "elongated" effects. To keep the correct
aspect ratio, select the
4:3 Aspect Ratio
button.
Pan & Scan – the live window behaves in the normal R1SC OS
way. Scrolling or resizing the window results in panning
around the image which remains at the current scale. You
can check the current resolution by looking at the live
display Title Bar which shows the resolution in pixels x lines.
4:3 aspect ratio/Free aspect ratio
These, as suggested above, are used in conjunction with Auto-
Zoom.
4:3 aspect ratio – the aspect ratio of the image remains fixed
whatever the display size.
Free aspect ratio – the aspect ratio corresponds to the shape of
the resized window.
