Just use the fromDivPixelToLatLng() function :)
(passing in the pixel coordinates you have calculated as per the image)
I know I strugged, to find a good example, of its use, from one of my
sites...
var overlay = null;
function update_map() {
if (overlay == null) {
overlay = new google.maps.OverlayView();
overlay.draw = function() {};
overlay.setMap(map);
}
var center = map.getCenter();
if (prevCenter && map.getZoom() == prevZoom) {
var point1 =
overlay.getProjection().fromLatLngToContainerPixel(center);...
shows one way to get a MapCanvasProjection object.
(you could possibly store the projection in a variable, rather than
calling overlay.getProjection()
each time)
