You'll want to wrap the x coordinate. Assuming you're using the default
projection, you can calculate the number of tiles horizontally across the
earth at a particular zoom level with:
1 << zoom
or
Math.pow(2, zoom)
Then use the mod operator. Something like:
{
getTileUrl: function(coord, zoom) {
var wrappedX = coord.x % (1 << zoom);
return "/tiles/" + zoom + "/" + wrappedX + "/" + coord.y;
},
tileSize: ...
...
}
BTW - you may want to take a look at the ImageMapType. Seems like it does
pretty much what you're doing right now.
The above code is untested, but should work!
