Last active December 31, 2015 02:29 — forked from Zverik/SingleTile.js

Use this with Leaflet map API to request a single dynamic tile to be generated when user stops panning. Request is made to PGRestAPI (Chubbs Spatial Server)

	initialize: function (url, options) {
	L.ImageOverlay.prototype.initialize.call(this, url, null, options);
