Properties

  Name Description
Dispatcher Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.)
IsClosed Gets or sets a value that indicates whether this figure's first and last segments are connected.
IsFilled Gets or sets a value that indicates whether the contained area of this PathFigure is to be used for hit-testing, rendering, and clipping.
Segments Gets or sets the collection of segments that define the shape of this PathFigure object.
StartPoint Gets or sets the Point where the PathFigure begins.

Methods

  Name Description
CheckAccess Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)
ClearValue Clears the local value of a dependency property. (Inherited from DependencyObject.)
Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
GetAnimationBaseValue Returns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
GetType Gets the Type of the current instance. (Inherited from Object.)
GetValue Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
ReadLocalValue Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
SetValue Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
ToString Returns a string that represents the current object. (Inherited from Object.)

Fields

  Name Description
IsClosedProperty Identifies the IsClosed dependency property.
IsFilledProperty Identifies the IsFilled dependency property.
SegmentsProperty Identifies the Segments dependency property.
StartPointProperty Identifies the StartPoint dependency property.

Remarks

The defining property of a PathFigure is its StartPoint, because it specifies the point from which the first contained line segment starts.

If you want a geometry where various figures are not connected to one another, you would specify multiple PathFigure objects within the PathFigureCollection, each with different StartPoint values.

Examples

The following example creates a simple PathGeometry made up of a single PathFigure with a LineSegment and displays it using a Path element. The PathFigure object's StartPoint is set to 10,20 and a LineSegment is defined with an end point of 100,130. The following illustration shows the PathGeometry created by this example.

A PathGeometry that contains a single LineSegment

<Canvas>
  <Path Stroke="Black" StrokeThickness="1">
    <Path.Data>
      <PathGeometry>
        <PathGeometry.Figures>
          <PathFigure StartPoint="10,20">
            <PathFigure.Segments>
              <LineSegment Point="100,130"/>
            </PathFigure.Segments>
          </PathFigure>
        </PathGeometry.Figures>
      </PathGeometry>
    </Path.Data>
  </Path>
</Canvas>

This example uses multiple segments in a PathFigure.

            <PathFigure.Segments>
              <BezierSegment Point1="100,0"
                Point2="200,200"
                Point3="300,100"/>
              <LineSegment Point="400,100" />
              <ArcSegment Size="50,50" RotationAngle="45"
                IsLargeArc="True" SweepDirection="Clockwise"
                Point="200,100"/>
            </PathFigure.Segments>
          </PathFigure>
        </PathGeometry.Figures>
      </PathGeometry>
    </Path.Data>
  </Path>
