In this example, the CornerPin node is composited over the original RGrad node.

As shown in the above image, manipulating the RGrad1 node while viewing the Over1
node results in the display of multiple controls. Changes made with one control modify
both. To break this link, copy the original RGrad node and connect it to the new node.

Important:

The MatchMove node is the only exception to this behavior. For nodes

above the MatchMove node, the onscreen controls appear without transformation.

Scaling Images and Changing Resolution

There are two types of scaling functions:

Functions that scale the size of the image in the frame, but do not change the actual
resolution (Scale, Move2D)

Functions that scale the size of the image in the frame, and also change the output
resolution (Resize, Zoom, Fit)

Additionally, the Crop, Window, and ViewPort nodes can be used to change the image
resolution by cutting into an image or expanding its borders.

Finally, the SetDOD node crops in an area of interest, called the Domain of
Definition (DOD).

The following tables discuss the differences between the scaling functions.
