src/ol/source/wmts.js, line 24
Name Type Description
options

WMTS options.

Name Type Description
attributions ol.AttributionLike | undefined

Attributions.
cacheSize number | undefined

Cache size. Default is 2048.
crossOrigin string | null | undefined

The crossOrigin attribute for loaded images. Note that you must provide a crossOrigin value if you are using the WebGL renderer or 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.
logo string | olx.LogoOptions | undefined

Logo.
tileGrid ol.tilegrid.WMTS

Tile grid. Required.
projection ol.ProjectionLike

Projection.
reprojectionErrorThreshold number | undefined

Maximum allowed reprojection error (in pixels). Default is 0.5. Higher values can increase reprojection performance, but decrease precision.
requestEncoding ol.source.WMTSRequestEncoding | string | undefined

Request encoding. Default is KVP.
layer string

Layer name as advertised in the WMTS capabilities. Required.
style string

Style name as advertised in the WMTS capabilities. Required.
tileClass function | undefined

Class used to instantiate image tiles. Default is ol.ImageTile.
tilePixelRatio number | undefined

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. Default is 1.
version string | undefined

WMTS version. Default is 1.0.0.
format string | undefined

Image format. Default is image/jpeg.
matrixSet string

Matrix set. Required.
dimensions Object | undefined

Additional "dimensions" for tile requests. This is an object with properties named like the advertised WMTS dimensions.
url string | undefined

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 ol.TileLoadFunctionType | undefined

Optional function to load a tile given a URL. The default is

function(imageTile, src) {
  imageTile.getImage().src = src;
};
urls Array.<string> | undefined

An array of URLs. Requests will be distributed among the URLs in this array.
wrapX boolean | undefined

Whether to wrap the world horizontally. Default is false.
Fires:

Extends

Methods

ol.source.WMTS.optionsFromCapabilities(wmtsCap, config){olx.source.WMTSOptions}

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.
