Change individual markers in google maps directions api V3

问题

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.

Do as they say on that page you linked to:

• Set the suppressMarkers option to true to prevent the default start and end markers from showing
• Create the images for the two new markers
• Create the markers with the position set to the start and end positions, and the icon set to the ones you created
