<ArcSegment SweepDirection="Clockwise"/> -or- <ArcSegment SweepDirection="CounterClockwise"/>
Property Value
Type: System.Windows.Media.SweepDirectionOne of the enumeration values that specifies the direction in which the arc is drawn. The default is Counterclockwise.
Dependency property identifier field: SweepDirectionProperty
For an ArcSegment with a given Size, RotationAngle, start point, and end Point, four different arcs are possible. Specifying the IsLargeArc property reduces the number of possible arcs to two: an arc drawn from the start point to the end Point in a Clockwise direction and an arc drawn from the start point to the end point in a Counterclockwise direction.
The following illustration shows two elliptical arcs that are identical except for their SweepDirection settings.
