import {optionsFromCapabilities} from 'ol/source/WMTS';

Generate source options from a capabilities object.

Name	Type	Description
wmtsCap	Object	An object representing the capabilities document.
config	Object	Configuration properties for the layer. Defaults for the layer will apply if not provided. Required config properties: layer - {string} The layer identifier. Optional config properties: matrixSet - {string} The matrix set identifier, required if there is more than one matrix set in the layer capabilities. projection - {string} The desired CRS when no matrixSet is specified. eg: "EPSG:3857". If the desired projection is not available, an error is thrown. requestEncoding - {string} url encoding format for the layer. Default is the first tile url format found in the GetCapabilities response. style - {string} The name of the style format - {string} Image format for the layer. Default is the first format returned in the GetCapabilities response. crossOrigin - {string|null|undefined} Cross origin. Default is undefined.

Returns:

WMTS source options object or null if the layer was not found.

Type Definitions

Options{Object}

Properties:

Name	Type	Argument	Default	Description
attributions	module:ol/source/Source~AttributionLike	<optional>		Attributions.
cacheSize	number	<optional>		Tile cache size. The default depends on the screen size. Will increase if too small.
crossOrigin	null | string	<optional>		The crossOrigin attribute for loaded images. Note that you must provide a crossOrigin value if you want to access pixel data with the Canvas renderer. See https://developer.mozilla.org/en-US/docs/Web/HTML/CORS_enabled_image for more detail.
tileGrid	module:ol/tilegrid/WMTS~WMTSTileGrid			Tile grid.
projection	module:ol/proj~ProjectionLike	<optional>		Projection. Default is the view projection.
reprojectionErrorThreshold	number	<optional>	0.5	Maximum allowed reprojection error (in pixels). Higher values can increase reprojection performance, but decrease precision.
requestEncoding	module:ol/source/WMTSRequestEncoding | string	<optional>	'KVP'	Request encoding.
layer	string			Layer name as advertised in the WMTS capabilities.
style	string			Style name as advertised in the WMTS capabilities.
tileClass	Class.<module:ol/ImageTile~ImageTile>	<optional>		Class used to instantiate image tiles. Default is module:ol/ImageTile~ImageTile.
tilePixelRatio	number	<optional>	1	The pixel ratio used by the tile service. For example, if the tile service advertizes 256px by 256px tiles but actually sends 512px by 512px images (for retina/hidpi devices) then tilePixelRatio should be set to 2.
format	string	<optional>	'image/jpeg'	Image format. Only used when requestEncoding is 'KVP'.
version	string	<optional>	'1.0.0'	WMTS version.
matrixSet	string			Matrix set.
dimensions	Object	<optional>		Additional "dimensions" for tile requests. This is an object with properties named like the advertised WMTS dimensions.
url	string	<optional>		A URL for the service. For the RESTful request encoding, this is a URL template. For KVP encoding, it is normal URL. A {?-?} template pattern, for example subdomain{a-f}.domain.com, may be used instead of defining each one separately in the urls option.
tileLoadFunction	module:ol/Tile~LoadFunction	<optional>		Optional function to load a tile given a URL. The default is function(imageTile, src) { imageTile.getImage().src = src; };
urls	Array.<string>	<optional>		An array of URLs. Requests will be distributed among the URLs in this array.
wrapX	boolean	<optional>	false	Whether to wrap the world horizontally.
transition	number	<optional>		Duration of the opacity transition for rendering. To disable the opacity transition, pass transition: 0.
