Well done Rob, tiles look very nice and smooth!
You may be interested in the JavaScript tile manager library I'm developing
atm. It already supports event handling (click and mousemove implemented;
mousedown, mouseup, dblclick, mouseover and mouseout are on the way) on
individual objects (circles, rectangles, squares and polygons implemented;
polylines are on the way) drawn server-side on the custom tiles. My library
exposes an API familiar to users of the standard Google Maps API. For
example:
var gm = google.maps;
...
var mgr = new TileMarkerManager(map);
var polypoints = [new gm.Point(20,10), new gm.Point(30,20),new
gm.Point(20,50), new gm.Point(10,40),new gm.Point(20,10)];
// polygon tile marker needs zoom and points
var polygonMarker = new PolyTileMarker(0, polypoints);
// circle tile marker needs zoom, radius and center point
var circleMarker = new CircleTileMarker(0, 20, gm.Point(100,100));
mgr.addMarkers([polygonMarker, circleMarker]);
// now add some listeners
// individual click listener for polygon marker
mgr.bind(polygonMarker, 'click', new function(point) {...});
// individual mouseover listener for circle marker
mgr.bind(circleMarker, 'mouseover', new function(point) {...});
// generic click listener that receives marker clicked as its first argument
mgr.bind('click', new function(marker, point) {...});
TileMarker objects are just container objects (no images or dom elements),
so performance is not a problem comparing with google.maps.Marker objects.
Also TileMarkerManager has some smarts in it to work fast with lots of
markers on all zoom levels.
Let me know if you are interested to be an early adopter. :-)
