What each control does
Section titled “What each control does”- Length is the length of the blur.
- Angle adjusts the angle of the blur.
- Repeat edge pixels: on holds the layer’s edge pixels outward. Off streaks the edge into transparency and past it, and the layer grows to hold the streak.
- Mix: how much of the result replaces the original.
- Matte and Invert drive the blur amount from another layer’s brightness, scaled by the blur amounts you set; see Effects.
