[Francophone] Transform et OpenLayer

[Pierre Muckensturm]

Aloha,
Mon php génère le javascript de ma page web, notamment la partie "openlayer".
...
<script type='text/javascript'>
     var map;
         function init() {
       map = new OpenLayers.Map("map_id", {});
       //map.addControl(new OpenLayers.Control.MousePosition());
       var osm_layer = new OpenLayers.Layer.OSM();
       map.addLayer(osm_layer);

       map.zoomToExtent(new OpenLayers.Bounds(446909,6316526,451696,6318943));
               map.zoomToScale(12000);
//              map.events.register("mousemove", map, function(e) {
//                      var position = this.events.getMousePosition(e);
//                      OpenLayers.Util.getElement("coords").innerHTML
= position;
//              });
               var markers = new OpenLayers.Layer.Markers( "Markers" );
               map.addLayer(markers);
               var size = new OpenLayers.Size(125,26);
               var size2 = new OpenLayers.Size(12,26);
               var offset = new OpenLayers.Pixel(-(size.w/2), -size.h);
               var offset2 = new OpenLayers.Pixel(0,0);
               var icon = new
OpenLayers.Icon('./galerie/logo-small.png',size,offset);
               markers.addMarker(new OpenLayers.Marker(new
OpenLayers.LonLat(448835,6318174),icon));
               var halfIcon = icon.clone();
               var icon2 = new
OpenLayers.Icon('./galerie/icon_marker.png',size2,offset2);

               //recupération des coordonnées des centroides depuis la
base oracle
en EPSG:2154 et transformation en EPSG:900913
               markers.addMarker(new
OpenLayers.Marker(OpenLayers.Projection.transform(OpenLayers.Point(775133.95,6907235.95),
EPSG:2154,EPSG:900913),icon2);
[...]
};

   </script>
La partie "marker" vous semble-t'elle correcte, notamment la transformation ?
Ma carte reste désespérément blanche.

D'avance merci pour tout conseil donné au jeune padawan que je suis.
