Shrink/Grow/Opening/Closing
The Mode, Shape, Radius, and Iterations controls let you refine the edges of mattes in a variety
of ways, shrinking and growing a matte with problem edges, or opening and closing holes that
appear within a matte.
 Mode: Lets you choose how you want to modify the alpha channel/key. You can choose
Shrink or Grow to dilate or erode the edges of the matte with great accuracy. Or, you can
choose Opening or Closing to plug or expand holes to clean up a ragged matte.
 Shape: Lets you choose how corners and angles in the edges of the key are handled
when you grow or shrink it. Circle is the default, and results in even expansion around
the surface of the key that eventually averages all angles into a circular shape if you
use extreme radius settings. Square averages all angles into a more rectangular shape
if you use extreme radius settings. Diamond averages all angles into a diamond shape
if you use extreme radius settings.
 Radius: Adjusts how much to shrink, grow, open, or close the key.
 Iterations: Alters the effect of the Operator Radius setting to create more extreme
adjustments.
