    • Example

    The following example creates a map and changes its size from 640 by 400 pixels to 800 by 600 pixels. 
    <div id="mapContainer"  style="width: 640px; height: 400px;"></div>
<script type="text/javascript">
    var map0 = new TMap(mapContainer, 25.7590256665386, -80.3738769902151, 15, mapLoaded, 1, true, "", "hybrid");
   
    function mapLoaded() {
        var layer0=map0.AddLayer();
        polygon0=layer0.AddPolygon("25.7609634245936,-80.3810464518457;" + //You need to add the vertexes of
                                       "25.7611702422549,-80.3686484471929;" +  //the polygon in a string.
                                       "25.7469942429429,-80.3680055121408;" +

                                       "FILL_COLOR=0xAACCFF;FILL_ALPHA=50;LINE_COLOR=0xFFFFFF;LINE_WIDTH=2;LINE_ALPHA=100");
            //Set polygon on click listener
         polygon0.SetOnClickListener(
                function(){
                    alert("polygon0 clicked.");
