Properties

DefiningGeometry

Gets a value that represents the Geometry of the Shape.

protected override Geometry DefiningGeometry { get; }

Property Value

Geometry

The Geometry of the Shape.

EndAngle

Gets or sets the final angle from which the arc will be drawn.

public double EndAngle { get; set; }
