Dim m As Marker = gmap.AddMarker(30, 30, "test")
Dim jo As JavaObject = m
jo.GetFieldJO("jsObject").RunMethod("eval", Array($"
 var image = {
   url: 'https://developers.google.com/maps/documentation/javascript/examples/full/images/beachflag.png',
    size: new google.maps.Size(16, 16),
    origin: new google.maps.Point(0, 0),
    anchor: new google.maps.Point(0, 16)
   };

   this.setIcon(image);
"$))

Sub AddSizedMarker(g As GoogleMap,lat As Double,lng As Double, title As String, iconuri As String, iconsize As Int) As Marker
    Dim m As Marker = g.AddMarker(lat,lng, title)
    Dim jo As JavaObject = m
    jo.GetFieldJO("jsObject").RunMethod("eval", Array($"
 var image = {
   url: '${iconuri}',
    size: new google.maps.Size(${iconsize},${iconsize}),
    scaledSize:new google.maps.Size(${iconsize},${iconsize}),
