8.24 Intelligent Scissors
8.24.1 Overview
The Intelligent Scissors can be used to select contiguous areas of similar color
weight in a fashion similar to the Fuzzy Selection Tool. The primary difference is that
the scissor tool creates the selection area one line at a time. Clicking with Button1 will
create nodes that are intelligently joined using lines that attempt to follow color weights.
Once the area is closed, clicking inside the new area will render the selection area. It is
at this time that the key modifications can be used to change the selection method.

Feather The Feather slider sets the amount of feathering to create around the ren-
dered selection area. Feathering softens the edge of the selection by the speci-
fied number of pixels. See also:Feather Selection.
Antialiasing The Antialiasing button toggles the rendering of aliased edges on the
selection boundary. Aliasing produces smoother curves and angles and is rec-
ommended for most uses.
