Calculate and Set Bounds (Bounding Box) from Points in Google Maps Flash [Update]

I’ve got a list of points in my database, which I want to show neatly in a Google Maps Flash Map.

Thus, I …

  1. calculate the bounding box around these points
  2. calculate the center of this bounding box
  3. set the zoom level of the map in a way that the zoomed cutout contains all points
  4. set the center of the map

//1.
var bounds:LatLngBounds = new LatLngBounds();
for each(var mapObject in tripMessages){
    var currentLatLon:LatLng = new LatLng(mapObject.latitude, 
	                                       mapObject.longitude);
    bounds.extend(currentLatLon);
}
 
//2.
var center:LatLng = bounds.getCenter();
 
//3.
map.setZoom(map.getBoundsZoomLevel(bounds));
 
//4.
map.setCenter(center);
