Feather

The interactive controls for the native Feather live effect consist of a single slider:

Stylism Feather Controls

A. Blur Slider

The blur slider thumb control may be dragged along the blur arm to change the feather’s blur radius, between 0.2 and 250 pt. The value increases away from the center circle. When the cursor is hovering over the control or dragging it, the current blur radius is displayed. The blur slider can also be clicked anywhere along its length to move the blur thumb immediately to that position. While dragging the blur slider, in addition to the common keypresses (see Stylism Annotated Controls and Common Drag Keypresses), the following keypresses can be used:

• Shift: Constrains the blur radius to integer values.

Doubleclicking the control brings up a dialog which allows you to enter the blur radius numerically.
