jimmy-collazos / TrajectoryMarkers.js
Created July 18, 2012 11:17
Esta librería se usa para poner multiples marcas (generalmente flechas indicando la dirección) en un trayecto y mostrar sólo las que no colapsan entre si; dejando una distancia en pixeles entre dos marcas.
var TrajectoryMarkers = function(map, arrayMarkers, separation){
this.set('markers', arrayMarkers || []);
this.set('separation', separation || 50);//pixeles de separación
this.setMap(map);
}
TrajectoryMarkers.prototype = new google.maps.OverlayView();
TrajectoryMarkers.prototype.onAdd = function(){
var self = this;
google.maps.event.addListener(this.getMap(), 'zoom_changed', function(){
self.draw();
