The Circle effect creates a customizable solid disk or ring.

This effect works with 8-bpc color.

Edge

None creates a solid disk. The other options all create rings. Each option corresponds to a different set of properties that determine the shape and edge treatment of the ring:

Edge Radius

The difference between the Edge Radius property and the Radius property is the thickness of the ring.

Thickness

The Thickness property sets the ring’s thickness.

Thickness * Radius

The product of the Thickness property and the Radius property is the ring’s thickness.

Thickness & Feather * Radius

The product of the Thickness property and the Radius property is the ring’s thickness. The product of the Feather property and the Radius property is the ring’s feather.

Feather

The thickness of the feather.

Invert Circle

Inverts the matte.

Blending Mode

The blending mode used to combine the shape and the original layer. These blending modes behave like those in the Timeline panel, except for None, which displays only the shape, without the original layer.
