Remarks

Create a Map Line

The following example creates a map line:

View Example

C#

ItemStorage.Items.Add(new MapLine { Point1 = new GeoPoint(-30, 20), Point2 = new GeoPoint(-35, 25), Stroke = Color.Red, StrokeWidth = 4 });

VB.NET

ItemStorage.Items.Add(New MapLine With {.Point1 = New GeoPoint(-30, 20), .Point2 = New GeoPoint(-35, 25), .Stroke = Color.Red, .StrokeWidth = 4})

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:

C#

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);

VB.NET

Dim line As MapLine = New MapLine() With {
     .Point1 = New GeoPoint(0, 0),
     .Point2 = New GeoPoint(-10, -30),
     .StrokeWidth = 2,
     .Stroke = 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)
