Create a Map Line

The following example creates a map line:

Map Line

ItemStorage.Items.Add(new MapLine { Point1 = new GeoPoint(-30, 20),
                                    Point2 = new GeoPoint(-35, 25),
                                    Stroke = Color.Red,

Add Map Line Caps

You can display shapes at the beginning and at the end of map lines. Use the StartLineCap and EndLineCap properties for this purpose.

The following example specifies the end cap template and shows the default arrow for the MapLine start cap:

MapLineCap

MapLine line = new MapLine() { Point1 = new GeoPoint(0, 0), 
                               Point2 = new GeoPoint(-10, -30), 
                               StrokeWidth = 2, 
                               Stroke = System.Drawing.Color.Blue };
line.StartLineCap.Visible = true;
line.StartLineCap.Length = 20;
line.StartLineCap.Width = 10;

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

mapItemStorage1.Items.Add(line);
