MapPolylineBase.EndLineCap Property

Specifies end cap settings.

Namespace: DevExpress.Xpf.Map

Assembly: DevExpress.Xpf.Map.v21.2.dll

Declaration

public MapLineCap EndLineCap { get; set; }

Property Value

Type Description
MapLineCap

Contains end cap settings.

Remarks

Display the Default Arrow

Use the EndLineCap property to display a shape at the end of a MapPolylineBase descendant. The default cap shape is an arrow. Set the Visible property to true to display the arrow:

Map polyline and spline caps

Display a Custom Shape

To display a custom shape, set the MapLineCap.Geometry property to the PathGeometry object that defines a cap shape.

Use the MapLineCap.Width and MapLineCap.Length properties to specify dimensions of the default arrow or a custom shape.

The following example defines a custom end cap shape and its dimensions:

<Window.Resources>
  <PathGeometry x:Key="CapShape" Figures="M-0.38,-0.5 L 0.44,-0.05 C 0.44,-0.05 0.5,0 0.44,0.05 
                               L 0.44,0.05 L -0.38,0.5 C -0.38,0.5 -0.44,0.5 -0.41,0.4 L -0.41,0.4 
                               L -0.13,0 L -0.41,-0.4 C -0.41,-0.4 -0.44,-0.475 -0.38,-0.5 Z"/>
</Window.Resources>
<Grid>
  <!--...-->
  <dxm:MapPolyline Stroke="Blue">
    <dxm:MapPolyline.EndLineCap>
      <dxm:MapLineCap Visible="True" Length="18" Width="8" Geometry="{StaticResource CapShape}"/>
    </dxm:MapPolyline.EndLineCap>
    <!--...-->
  </dxm:MapPolyline>
  <dxm:MapSpline Stroke="Blue">
    <dxm:MapSpline.EndLineCap>
      <dxm:MapLineCap Visible="True" Length="10" Width="10" Geometry="{StaticResource CapShape}"/>
    </dxm:MapSpline.EndLineCap>
    <!--...-->
  </dxm:MapSpline>
  <!--...-->
</Grid>

Result:

Map polyline and spline custom caps
