Question

I’m looking to change the marker icons when using the DirectionsRender within a google map. I’ve figured out from here how to change both the markers to the same icon, but I am looking for custom icons on both the start and end points. Any ideas?

Edit: I’m looking for how to assign separate icons to the start and end markers. I know how to change it for both, but having different marker icons is proving difficult.

For those that need an example like I did, here’s a basic one:

 // Map and directions objects
 var map = new google.maps.Map( element, options );
 var service = new google.maps.DirectionsService();
 var directions = new google.maps.DirectionsRenderer({suppressMarkers: true});

 // Start/Finish icons
 var icons = {
  start: new google.maps.MarkerImage(
   // URL
   'start.png',
   // (width,height)
   new google.maps.Size( 44, 32 ),
   // The origin point (x,y)
   new google.maps.Point( 0, 0 ),
   // The anchor point (x,y)
   new google.maps.Point( 22, 32 )
  ),
  end: new google.maps.MarkerImage(
   // URL
   'end.png',
   // (width,height)
   new google.maps.Size( 44, 32 ),
   // The origin point (x,y)
   new google.maps.Point( 0, 0 ),
   // The anchor point (x,y)
   new google.maps.Point( 22, 32 )
  )
 };

service.route( { origin: origin, destination: destination }, function( response, status ) {
 if ( status == google.maps.DirectionsStatus.OK ) {
  display.setDirections( response );
  var leg = response.routes[ 0 ].legs[ 0 ];
  makeMarker( leg.start_location, icons.start, "title" );
  makeMarker( leg.end_location, icons.end, 'title' );
 }
});
function makeMarker( position, icon, title ) {
 new google.maps.Marker({
  position: position,
  map: map,
  icon: icon,
  title: title
 });
}

The response from a route request returns a leg(s) depending on the number of stops on your route. I am only doing a A to B route, so just take the first leg, and get the position of where the markers need to go, and create markers for those spots.
