Description
The soft edges are created on the distorted image, i.e. it is available at the borders of the distorted image.
Using the Soft Edge user interface, you can create a Soft Edge area and/or a blanked area on each of the four edges of the image.
Each edge where the blending is to be applied has a
grid of anchor points . Depending on the selected level, the amount of anchor
points can vary from 4 to 25. By default the grid is rectangular, symmetric and it covers 12.5% of the width or height of the image.

Soft Edge anchor points
The anchor points are numbered from 0 to 24 and can be moved to the desired location to determine the size and shape of the Soft
Edge area on the selected edge. By moving anchor points zero to four, a blanked area is created.
