TileLayer's ZoomOffset option don't work in 1.3.0 #6004
Closed
Description
How to reproduce
- Leaflet version I'm using: 1.3.0
- Browser (with version) I'm using: Chrome
- OS/Platform (with version) I'm using: MacOs
- Add any TileLayer to map.
- Set zoomOffset option to some value
What behaviour I'm expecting and which behaviour I'm seeing
Tile request urls have zoom + offset.
Minimal example reproducing the issue
- this example is as simple as possible
- this example does not rely on any third party code
Mapbox: L.tileLayer('//api.mapbox.com/styles/v1/mapbox/streets-v9/tiles/{z}/{x}/{y}?access_token=' + token, {

tileSize: 512,
zoomOffset: -10,
detectRetina: true,
maxZoom: 21
}),
i think that problem is in z: coords.z ? coords.z : this._getZoomForUrl() in getTileUrl method.
this._getZoomForUrl() is never reached...
// @section Extension methods
// @uninheritable
// Layers extending `TileLayer` might reimplement the following method.
// @method getTileUrl(coords: Object): String
// Called only internally, returns the URL for a tile given its coordinates.
// Classes extending `TileLayer` can override this function to provide custom tile URL naming schemes.
getTileUrl: function (coords) {
var data = {
r: retina ? '@2x' : '',
s: this._getSubdomain(coords),
x: coords.x,
y: coords.y,
z: coords.z ? coords.z : this._getZoomForUrl()
};
if (this._map && !this._map.options.crs.infinite) {
var invertedY = this._globalTileRange.max.y - coords.y;
if (this.options.tms) {
data['y'] = invertedY;
}
data['-y'] = invertedY;
}
return template(this._url, extend(data, this.options));
},
