Each PathGeometry object defines a collection of PathFigure objects. Each of the PathFigure objects is composed of one or more PathSegment objects, such as ArcSegment and LineSegment, which actually define their shape.
The filled area of the PathGeometry is defined by taking all of the contained PathFigure objects that have their IsFilled property set to true and applying the FillRule to determine the enclosed area.
This example shows how to create a line segment. To create a line segment, use the PathGeometry, PathFigure, and LineSegment classes.
The following examples draw a LineSegment from (10, 50) to (200, 70). The following illustration shows the resulting LineSegment; a grid background was added to show the coordinate system.

[xaml]
In Extensible Application Markup Language (XAML), you may use attribute syntax to describe a path.
<Path Stroke="Black" StrokeThickness="1" Data="M 10,50 L 200,70" />
[xaml]
(Note that this attribute syntax actually creates a StreamGeometry, a lighter-weight version of a PathGeometry. For more information, see the Path Markup Syntax page.)
In XAML, you may also draw a line segment by using object element syntax. The following is equivalent to the previous XAML example.
<Path Stroke="Black" StrokeThickness="1"> <Path.Data> <PathGeometry> <PathFigure StartPoint="10,50"> <LineSegment Point="200,70" /> </PathFigure> </PathGeometry> </Path.Data> </Path>
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.

The curve has control points of (100, 0) and (200, 200). |

| How to: Create Multiple Subpaths Within a PathGeometry | This example shows how to create multiple subpaths in a PathGeometry. To create multiple subpaths, you create a PathFigure for each subpath. |
| How to: Control the Fill of a Composite Shape | The FillRule property of a GeometryGroup or a PathGeometry, specifies a "rule" which the composite shape uses to determine whether a given point is part of the geometry. There are two possible values for FillRule: EvenOdd and Nonzero. The following sections will describe how to use these two rules. |
