 Example

The following code creates a new MapView using a <DIV> element called "mapview" that we've declared in the HTML code of the page. Then it checks if there are any DecorationLayer-s and if not - adds one with a Marker in it:

JavaScript

var m = MindFusion.Mapping;// create a new instance of the mapView
var view = new m.MapView(document.getElementById("mapView"));
view.theme = "light";
....................
....................if(view.overlays.count() == 0)
{   //add a new DecorationLayer
   var markers = new m.DecorationLayer("Images");   // create some markers with images
   var mark = new m.Marker(new m.LatLong(-22.951916, -43.210487));
   mark.imageSrc = "./images/christ_redeemer.png";
   mark.text = "Christ the Redeemer";
   mark.visible = false;
   markers.decorations.add(mark);   view.layers.add(markers);
}
