How to: Modify the Cap at the End of a Line or Segment

This example shows how to modify the shape at the start or end of an open Shape element. To change the cap at the beginning of an open Shape, use its StrokeStartLineCap property. To change the cap at the end of an open Shape, use its StrokeEndLineCap property. To view the available line caps, see the PenLineCap enumeration.

NoteNote:

This property only affects an open shape, such as a Line, a Polyline, or an open Path element.

The following example draws four Polyline elements and uses a different set of shapes on the ends of each.

Example

<TextBlock Grid.Column="3" Grid.Row="0" Grid.ColumnSpan="2">
  <Bold>Line Caps</Bold>
</TextBlock>
<TextBlock Grid.Column="3" Grid.Row="1">Flat</TextBlock>
<Polyline
  Points="50,50 75,30 100,100 130,40"
  Stroke="Red"
  StrokeThickness="20"
  StrokeStartLineCap="Flat"
  StrokeEndLineCap="Flat"
  Grid.Row="1" Grid.Column="4"/>

<TextBlock Grid.Column="3" Grid.Row="2">Square</TextBlock>
<Polyline
  Points="50,50 75,30 100,100 130,40"
  Stroke="Red"
  StrokeThickness="20"
  StrokeStartLineCap="Square"
  StrokeEndLineCap="Square"    
  Grid.Row="2" Grid.Column="4"/>

<TextBlock Grid.Column="3" Grid.Row="3">Round</TextBlock>
<Polyline
  Points="50,50 75,30 100,100 130,40"
  Stroke="Red"
  StrokeThickness="20"
  StrokeStartLineCap="Round"
  StrokeEndLineCap="Round"  
  Grid.Row="3" Grid.Column="4"/>

<TextBlock Grid.Column="3" Grid.Row="4">Triangle</TextBlock>
<Polyline
  Points="50,50 75,30 100,100 130,40"
  Stroke="Red"
  StrokeThickness="20"
  StrokeStartLineCap="Triangle"
  StrokeEndLineCap="Triangle"     
  Grid.Row="4" Grid.Column="4"/>
