Remarks

The OuterShadowEffect class exposes properties that you can use to configure the outer shadow effect:

BlurRadius

Specifies the outer shadow’s blur radius.

Angle

Specifies the angle to offset the shadow.

Distance

Specifies how far to offset the shadow.

ColorSpecifies the outer shadow color.HorizontalScale | VerticalScaleSpecifies the horizontal and vertical scale factors of the shadow.HorizontalSkew | VerticalSkew

Specifies the horizontal and vertical skew angles of the shadow. This property is measured in degrees and can have values in the (-90, 90) range.

RotateWithShapeSpecifies whether the shadow rotates with the shape.

The following code snippet applies an outer shadow effect to a shape:
