Example #1
Source File: LiveAtlasTileLayer.ts    From LiveAtlas with Apache License 2.0 6 votes vote down vote up 
// @method createTile(coords: Object, done?: Function): HTMLElement
	// Called only internally, overrides GridLayer's [`createTile()`](#gridlayer-createtile)
	// to return an `<img>` HTML element with the appropriate image URL given `coords`. The `done`
	// callback is called when the tile has been loaded.
	createTile(coords: Coords, done: DoneCallback) {
		const tile = this.tileTemplate.cloneNode(false) as LiveAtlasTileElement;
		this.loadQueue.push(tile);

		tile.onload = () => {
			URL.revokeObjectURL(tile.src); //Revoke the object URL as we don't need it anymore

			this._tileOnLoad(done, tile);
			this.loadingTiles.delete(tile);
			this.tickLoadQueue();
		};

		tile.onerror = () => {
			this._tileOnError(done, tile, LiveAtlasTileLayer.genericLoadError);
			this.loadingTiles.delete(tile);
			this.tickLoadQueue();
		};

		tile.url = this.getTileUrl(coords);
		tile.callback = done;

		this.tickLoadQueue();
