displayWindow Background The frame size to output in the event that the fg and bg inputs
are different sizes:
• Background - output the frame size of the /jointfilesconvert/368881/bg input.
• Foreground - output the frame size of the fg input.
• Union - output a combination of the bg and fg inputs' frame
sizes.
• Intersection - output an intersection of the /jointfilesconvert/368881/bg and fg inputs'
frame sizes. This restricts the output to the area where the
two frame sizes overlap.
clampAlpha enabled When enabled, the output alpha channel is clamped to the 0-1
range. Color channels (RGB) are not affected.
ImageOver
This node layers images together using the Over compositing algorithm: F+B(1-f). This layers the foreground over
the background according to the alpha of the foreground. This is the most commonly used operation. It's used when
layering a foreground element over a background plate.
Also see ImageUnder on page268.
