How to: Create a LineSegment in a PathGeometry

 

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.

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>  

Dim myPathFigure As New PathFigure()  
            myPathFigure.StartPoint = New Point(10, 50)  
  
            Dim myLineSegment As New LineSegment()  
            myLineSegment.Point = New Point(200, 70)  
  
            Dim myPathSegmentCollection As New PathSegmentCollection()  
            myPathSegmentCollection.Add(myLineSegment)  
  
            myPathFigure.Segments = myPathSegmentCollection  
  
            Dim myPathFigureCollection As New PathFigureCollection()  
            myPathFigureCollection.Add(myPathFigure)  
  
            Dim myPathGeometry As New PathGeometry()  
            myPathGeometry.Figures = myPathFigureCollection  
  
            Dim myPath As New Path()  
            myPath.Stroke = Brushes.Black  
            myPath.StrokeThickness = 1  
            myPath.Data = myPathGeometry
