谷歌地圖API v3箭頭縮放級別

Question

我試圖使用谷歌地圖APT V3繪製多邊形箭頭。見下面的代碼。問題是當我縮小地圖箭頭頭保持不變時。任何方式來調整箭頭的縮放級別？

var myCoordinates = [ 
new google.maps.LatLng(54.065836, -7.415771), 
new google.maps.LatLng(53.219191, -7.261963) 
]; 
     var polyOptions = { 
      path: myCoordinates, 
      strokeColor: "#FF0000", 
      strokeOpacity: 1, 
      strokeWeight: 3 
, icons: [{ icon: { path: google.maps.SymbolPath.FORWARD_OPEN_ARROW, scale: 2 }, offset: "100%"}] 
     } 
     var it = new google.maps.Polyline(polyOptions); 
     it.setMap(map);
