PenLineCap Enumeration

Describes the shape at the end of a line or segment.

Namespace:  System.Windows.Media
Assembly:  PresentationCore (in PresentationCore.dll)
public enum PenLineCap
<object property="enumerationMemberName" .../>
Member nameDescription
FlatA cap that does not extend past the last point of the line. Comparable to no line cap.
SquareA rectangle that has a height equal to the line thickness and a length equal to half the line thickness.
RoundA semicircle that has a diameter equal to the line thickness.
TriangleAn isosceles right triangle whose base length is equal to the thickness of the line.

The following illustration shows the available cap styles for lines or segments. The red portion of the line shows the extra area added by the line cap setting.

PenLineCap settings

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.

<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"/>
