Description

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.

Edge area on the selected edge. By moving anchor points zero to four, a blanked area is created.
