Freezable Features: Because PathSegment objects inherit from the Freezable class, they provide several special features: they can be declared as resources, shared among multiple objects, made read-only to improve performance, cloned, and made thread-safe. For more information about the different features that are provided by Freezable objects, see the Freezable Objects Overview.Notes to Inheritors: Although this class is abstract, it is not publicly extensible.
This example shows how to create a shape using the PathGeometry class. PathGeometry objects are composed of one or more PathFigure objects; each PathFigure represents a different "figure" or shape. Each PathFigure is itself composed of one or more PathSegment objects, each representing a connected portion of the figure or shape. Segment types include LineSegment, ArcSegment, and BezierSegment.
<Path Stroke="Black" StrokeThickness="1"> <Path.Data> <PathGeometry> <PathGeometry.Figures> <PathFigureCollection> <PathFigure IsClosed="True" StartPoint="10,100"> <PathFigure.Segments> <PathSegmentCollection> <LineSegment Point="100,100" /> <LineSegment Point="100,50" /> </PathSegmentCollection> </PathFigure.Segments> </PathFigure> </PathFigureCollection> </PathGeometry.Figures> </PathGeometry> </Path.Data> </Path>
The following illustration shows the shape created in the previous example.
A triangle created with a PathGeometry
The previous example showed how to create a relatively simple shape, a triangle. A PathGeometry can also be used to create more complex shapes, including arcs and curves. For examples, see Create an Elliptical Arc, Create a Cubic Bezier Curve, and Create a Quadratic Bezier Curve.
This example is part of larger sample; for the complete sample, see the Geometries Sample.

|How to: Create a Cubic Bezier Curve|| |
This example shows how to create a cubic Bezier curve. To create a cubic Bezier curve, use the PathGeometry, PathFigure, and BezierSegment classes. To display the resulting geometry, use a Path element, or use it with a GeometryDrawing or a DrawingContext. In the following examples, a cubic Bezier curve is drawn from (10, 100) to (300, 100). The curve has control points of (100, 0) and (200, 200).
