Examples

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.

The following example uses a PathGeometry to create a triangle. The PathGeometry is displayed using a Path element.

XAML

<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 How to: Create an Elliptical Arc, How to: Create a Cubic Bezier Curve, and How to: Create a Quadratic Bezier Curve.

This example is part of larger sample; for the complete sample, see the Geometries Sample.
