Hello all,
I've used the Google maps geometry library to store a route on a map. Now I want to load that route, therefore I use the following code :

C#

var encoded = $("#ContestRouteInfo").val();
map.config.routingPoly = new google.maps.Polyline({
    map: map.config.map,
    strokeColor: '#fc4c02',
    strokeOpacity: 0.75,
});

map.config.path = google.maps.geometry.encoding.decodePath(encoded);
map.config.routingPoly.setPath(map.config.path);

This runs fine, the route is perfectly drawn on the map, however after loading I want to zoom the map and (re)set the center of the map so the route is visible. How can I determine the perfect zoom level and center of the map?

i think you have to use this code inside your "google.maps.event.addListener" function

C#

if (place.geometry.viewport) {
           map.fitBounds(place.geometry.viewport);
       } else {
           map.setCenter(place.geometry.location);
           map.setZoom(14); // you can set perfect zoom level here.
       }
