- /**
- * @typedef {object} WebMapTileServiceImageryProvider.ConstructorOptions
- *
- * Initialization options for the WebMapTileServiceImageryProvider constructor
- *
- * @property {Resource|string} url The base URL for the WMTS GetTile operation (for KVP-encoded requests) or the tile-URL template (for RESTful requests). The tile-URL template should contain the following variables: {style}, {TileMatrixSet}, {TileMatrix}, {TileRow}, {TileCol}. The first two are optional if actual values are hardcoded or not required by the server. The {s} keyword may be used to specify subdomains.
- * @property {string} [format='image/jpeg'] The MIME type for images to retrieve from the server.
- * @property {string} layer The layer name for WMTS requests.
- * @property {string} style The style name for WMTS requests.
- * @property {string} tileMatrixSetID The identifier of the TileMatrixSet to use for WMTS requests.
- * @property {boolean} [enablePickFeatures] If true, {@link WebMapTileServiceImageryProvider#pickFeatures} will invoke
- * the GetFeatureInfo operation on the WMTS server and return the features included in the response. If false,
- * {@link WebMapTileServiceImageryProvider#pickFeatures} will immediately return undefined (indicating no pickable features)
- * without communicating with the server. Set this property to false if you know your WMTS server does not support
- * GetFeatureInfo or if you don't want this provider's features to be pickable.
- * Defaults to true for KVP encoding. For RESTful encoding, defaults to true only when
- * {@link WebMapTileServiceImageryProvider.ConstructorOptions#getFeatureInfoUrl} is specified, and false otherwise.
- * @property {object} [getFeatureInfoParameters] Additional parameters to include in GetFeatureInfo requests. Keys are lowercased internally.
- * @property {Resource|string} [getFeatureInfoUrl] The GetFeatureInfo URL of the WMTS service. If not specified, the value of <code>url</code> is used.
- * @property {GetFeatureInfoFormat[]} [getFeatureInfoFormats=WebMapTileServiceImageryProvider.DefaultGetFeatureInfoFormats] The formats
- * in which to try WMTS GetFeatureInfo requests.
- * @property {Rectangle} [rectangle=Rectangle.MAX_VALUE] The rectangle covered by the layer.
- * @property {TilingScheme} [tilingScheme] The tiling scheme corresponding to the organization of the tiles in the TileMatrixSet.
- * @property {Ellipsoid} [ellipsoid] The ellipsoid. If not specified, the WGS84 ellipsoid is used.
- * @property {number} [tileWidth=256] The tile width in pixels.
- * @property {number} [tileHeight=256] The tile height in pixels.
- * @property {number} [minimumLevel=0] The minimum level-of-detail supported by the imagery provider.
- * @property {number} [maximumLevel] The maximum level-of-detail supported by the imagery provider, or undefined if there is no limit.
- * @property {Array} [tileMatrixLabels] A list of identifiers in the TileMatrix to use for WMTS requests, one per TileMatrix level.
- * @property {Credit|string} [credit] A credit for the data source, which is displayed on the canvas.
- * @property {string|string[]} [subdomains='abc'] The subdomains to use for the <code>{s}</code> placeholder in the URL template.
- * If this parameter is a single string, each character in the string is a subdomain. If it is
- * an array, each element in the array is a subdomain.
- * @property {Clock} [clock] A Clock instance that is used when determining the value for the time dimension. Required when `times` is specified.
- * @property {TimeIntervalCollection} [times] TimeIntervalCollection with its <code>data</code> property being an object containing time dynamic dimension and their values.
- * @property {object} [dimensions] A object containing static dimensions and their values.
