Feathering mask edges
Using the Mask Feather property, you make mask edges hard-edged or soft-edged
(feathered). By default, the feather width straddles the mask edge, half inside and half
outside. For example, if you set the feather width to 25, the feathering extends 12.5 pixels
inside the mask edge and 12.5 pixels outside it. You can also extend or contract the mask
edges to control where the mask feathering appears. See "Adjusting the edges of a mask"
on page 157.
