|
* <li><code>{height}</code>: The height of each tile in pixels.</li>

* @property {Resource|String} [pickFeaturesUrl] The URL template to use to pick features. If this property is not specified,
|
* {@link UrlTemplateImageryProviderBJ2000#pickFeatures} will immediately returned undefined, indicating no
|
* features picked. The URL template supports all of the keywords supported by the <code>url</code>
|
* parameter, plus the following:
|
* <ul>
|
* <li><code>{i}</code>: The pixel column (horizontal coordinate) of the picked position, where the Westernmost pixel is 0.</li>
|
* <li><code>{j}</code>: The pixel row (vertical coordinate) of the picked position, where the Northernmost pixel is 0.</li>

|
* <li><code>{format}</code>: The format in which to get feature information, as specified in the {@link GetFeatureInfoFormat}.</li>
|
* </ul>
|
* @property {Object} [urlSchemeZeroPadding] Gets the URL scheme zero padding for each tile coordinate. The format is '000' where
|
* each coordinate will be padded on the left with zeros to match the width of the passed string of zeros. e.g. Setting:
|
* urlSchemeZeroPadding : { '{x}' : '0000'}
|
* will cause an 'x' value of 12 to return the string '0012' for {x} in the generated URL.
|
* It the passed object has the following keywords:
|
* <ul>
|
* <li> <code>{z}</code>: The zero padding for the level of the tile in the tiling scheme.</li>
|
* <li> <code>{x}</code>: The zero padding for the tile X coordinate in the tiling scheme.</li>

|
* <li> <code>{reverseZ}</code>: The zero padding for the reverseZ coordinate of the tile in the tiling scheme.</li>
|
* </ul>
|
* @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 {Credit|String} [credit=''] A credit for the data source, which is displayed on the canvas.
|
* @property {Number} [minimumLevel=0] The minimum level-of-detail supported by the imagery provider. Take care when specifying
|
* this that the number of tiles at the minimum level is small, such as four or less. A larger number is likely
|
* to result in rendering problems.
|
* @property {Number} [maximumLevel] The maximum level-of-detail supported by the imagery provider, or undefined if there is no limit.
|
* @property {Rectangle} [rectangle=Rectangle.MAX_VALUE] The rectangle, in radians, covered by the image.
|
* @property {TilingScheme} [tilingScheme=WebMercatorTilingScheme] The tiling scheme specifying how the ellipsoidal
|
* surface is broken into tiles. If this parameter is not provided, a {@link WebMercatorTilingScheme}
|
* is used.
|
* @property {Ellipsoid} [ellipsoid] The ellipsoid. If the tilingScheme is specified,
|
* this parameter is ignored and the tiling scheme's ellipsoid is used instead. If neither
|
* parameter is specified, the WGS84 ellipsoid is used.
|
* @property {Number} [tileWidth=256] Pixel width of image tiles.
|
* @property {Number} [tileHeight=256] Pixel height of image tiles.
|
* @property {Boolean} [hasAlphaChannel=true] true if the images provided by this imagery provider
|
* include an alpha channel; otherwise, false. If this property is false, an alpha channel, if
|
* present, will be ignored. If this property is true, any images without an alpha channel will
|
* be treated as if their alpha is 1.0 everywhere. When this property is false, memory usage
|
* and texture upload time are potentially reduced.
|
* @property {GetFeatureInfoFormat[]} [getFeatureInfoFormats] The formats in which to get feature information at a
|
* specific location when {@link UrlTemplateImageryProviderBJ2000#pickFeatures} is invoked. If this
|
* parameter is not specified, feature picking is disabled.
|
* @property {Boolean} [enablePickFeatures=true] If true, {@link UrlTemplateImageryProviderBJ2000#pickFeatures} will
|
* request the <code>pickFeaturesUrl</code> and attempt to interpret the features included in the response. If false,
|
* {@link UrlTemplateImageryProviderBJ2000#pickFeatures} will immediately return undefined (indicating no pickable
|
* features) without communicating with the server. Set this property to false if you know your data
|
* source does not support picking features or if you don't want this provider's features to be pickable. Note
|
* that this can be dynamically overridden by modifying the {@link UriTemplateImageryProvider#enablePickFeatures}
|
* property.
|
* @property {Object} [customTags] Allow to replace custom keywords in the URL template. The object must have strings as keys and functions as values.
