3.3.6 The Sharpen Function
The concept of a partially selected pixel was introduced in
Section
3.1.2, in the discussion on antialiasing, and
was extended in Section
3.1.2, in the discussion on
feathering. The function Sharpen, from the Image:Select
menu, removes partially selected pixels in an image by transforming
those that are 50% or more selected into fully selected pixels and by
fully deselecting all the remaining pixels. Thus, this function
sharpens the active selection (not the image).
