Maps for WPF
図形の表示
KML > 図形の表示

A user can add various shapes to a map. In maps terminology, a shape is an object, which is tied to a latitude or longitude coordinate on a map. Many shapes are available, such as lines, polygons, circles and rectangles. You can also configure your shapes in a way that users can drag or edit them.

Adding a Polyline

You can connect geographic coordinates with a polyline by adding a VectorPolyline to the VectorLayer (see Vector data for more information). In this topic, you will create a 3-point polyline using XAML and code.

In XAML

Complete the following steps:

  1. Place the following XAML markup between the <c1:C1Maps> and </c1:C1Maps> tags:   
    <c1:VectorLayer Margin="2,0,-2,0">
         <c1:VectorPolyline Points="-80.15,42.12 -123.08,39.09, -3.90,30.85" StrokeThickness="3" Stroke="Red">
         </c1:VectorPolyline>
    </c1:VectorLayer>
    
  2. Press F5 to run the project.

In Code

Complete the following steps:

  1. In XAML view, add x:Name="C1Maps1" to the <c1:C1Maps> tag so that the object will have a unique identifier for you to call in code.
  2. Add the following code beneath the InitializeComponent() method:
    InitializeComponent();
                // Create layer and add it to the map
                VectorLayer VectorLayer1 = new VectorLayer();
                c1Maps1.Layers.Add(VectorLayer1);
                // Initial track
                Point[] pts = new Point[] { new Point(-80.15,42.12), new Point(-123.08,39.09),
    new Point(-3.90,30.85)};
                // Create collection and fill it
                PointCollection pcoll = new PointCollection();
                foreach (Point pt in pts)
                    pcoll.Add(pt);
                // Create a polyline and add it to the vector layer as a child
                VectorPolyline VectorPolyline1 = new VectorPolyline();
                VectorLayer1.Children.Add(VectorPolyline1);
                // Points
                VectorPolyline1.Points = pcoll;
                // Appearance
               VectorPolyline1.Stroke = new SolidColorBrush(Colors.Red);
               VectorPolyline1.StrokeThickness = 3;
    
  3. Press F5 to run the project.

Polygons

You can connect geographic coordinates with a polygon by adding a VectorPolygon to the VectorLayer (see Vector Data for more information). In this topic, you will create a 3-point polygon using XAML and code.

In XAML

Complete the following steps:

  1. Place the following XAML markup between the <c1:C1Maps> and </c1:C1Maps> tags:
    <c1:C1Maps x:Name="c1Maps1">
            <c1:VectorLayer Margin="2,0,-2,0">
                <c1:VectorPolygon Points="-80.15,42.12 -123.08,39.09, -3.90,30.85" StrokeThickness="3" Stroke="Red">
                </c1:VectorPolygon>
            </c1:VectorLayer>
        </c1:C1Maps>
    
  2. Press F5 to run the project.

In Code

Complete the following steps:

  1. In XAML view, add x:Name="C1Maps1" to the <c1:C1Maps> tag so that the object will have a unique identifier for you to call in code.
  2. Add the following code beneath the InitializeComponent() method:
                // Create layer and add it to the map
                VectorLayer VectorLayer1 = new VectorLayer();
                c1Maps1.Layers.Add(VectorLayer1);
                // Initial track
                Point[] pts = new Point[] { new Point(-80.15,42.12), new Point(-123.08,39.09),
    new Point(-3.90,30.85)};
                // Create collection and fill it
                PointCollection pcoll = new PointCollection();
                foreach (Point pt in pts)
                    pcoll.Add(pt);
                // Create a polygon and add it to the vector layer as a child
                VectorPolygon VectorPolygon1 = new VectorPolygon();
                VectorLayer1.Children.Add(VectorPolygon1);
     
                // Points
                VectorPolygon1.Points = pcoll;
                // Appearance
                VectorPolygon1.Stroke = new SolidColorBrush(Colors.Red);
                VectorPolygon1.StrokeThickness = 3;

Labels

In this topic, you will add a label to a geographic point ? the geographic coordinates of Erie, Pennsylvania (USA) - using a C1VectorLayer and a C1VectorPlacemark. For more information on vector layers, see Vector Layer.

In XAML

  1. Add the following XAML between the <c1:C1Maps> and </c1:C1Maps>tags:
    <c1:VectorLayer>
                <c1:VectorPlacemark LabelPosition="Left" GeoPoint="-80.107008,42.16389" StrokeThickness="2" Foreground="#FFEB1212" PinPoint="-80.010866,42.156831" Label="Erie, PA"/>
            </c1:VectorLayer>
    
  2. Run the project.

                //Create a vector placemark and add it to the layer
                VectorPlacemark vp1 = new VectorPlacemark();
                vl.Children.Add(vp1);
                // Set the placemark to a set of geographical coordinates
                vp1.GeoPoint = new Point(-80.107008, 42.16389);
                // Set the placemark's label and properties
                vp1.Label = "Erie, PA";
                vp1.FontSize = 12;
                vp1.Foreground = new SolidColorBrush(Colors.Red);
                vp1.LabelPosition = LabelPosition.Center;
