Remarks

Create a Map Polyline

The following example creates a map polyline:

Map Polyline

MapPolyline polyline = new MapPolyline() { StrokeWidth = 4,
                                           Stroke = Color.Yellow };
polyline.Points.AddRange(new GeoPoint[] { new GeoPoint(-29,130),
                                          new GeoPoint(-40,140),
                                          new GeoPoint(-20,150)});
ItemStorage.Items.Add(polyline);

Add Polyline Caps

You can display shapes at the beginning and at the end of map polylines. Use StartLineCap and EndLineCap properties for this purpose. The following example specifies the end cap template and shows the default arrow for the polyline start cap:

Map Spline Caps

MapPolyline polyline = new MapPolyline() { StrokeWidth = 2,
                                           Stroke = System.Drawing.Color.Blue };
polyline.Points.AddRange(new GeoPoint[] { new GeoPoint(-6, -4),
                                          new GeoPoint(-3, -10),
                                          new GeoPoint(-6, -20) });

polyline.StartLineCap.Visible = true;
polyline.StartLineCap.Length = 20;
polyline.StartLineCap.Width = 10;

polyline.EndLineCap.Visible = true;
polyline.EndLineCap.Template = new MapUnit[] { new MapUnit(-0.5, 0),
                                               new MapUnit(0, 0.5),
                                               new MapUnit(0.5, 0),
                                               new MapUnit(0, -0.5)};
polyline.EndLineCap.Length = 10;
polyline.EndLineCap.Width = 10;

ItemStorage.Items.Add(polyline);
