Hard edge: this option gives a hard contour to the smudged area.

割合

This option could be called "Smudge length" since it sets the length of the smudging effect in a stroke.

1: Rate=20 2: Rate=60 3: Rate=90


No erasing effect

If smudging will decrease alpha of some pixels; this alpha is not decreased if this option is checked, and so pixels are not erased. This is useful to fill a gap between two color areas.
