Type Definitions

Options{Object}

Properties:

Name	Type	Argument	Default	Description
attributions	module:ol/source/Source~AttributionLike	<optional>		Attributions.
attributionsCollapsible	boolean	<optional>	true	Attributions are collapsible.
cacheSize	number	<optional>		Initial tile cache size. Will auto-grow to hold at least the number of tiles in the viewport.
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.
imageSmoothing	boolean	<optional>	true	Deprecated. Use the interpolate option instead.
interpolate	boolean	<optional>	true	Use interpolated values when resampling. By default, linear interpolation is used when resampling. Set to false to use the nearest neighbor instead.
opaque	boolean	<optional>	false	Whether the layer is opaque.
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.
state	module:ol/source/Source~State	<optional>		Source state.
tileClass	Class.<module:ol/ImageTile~ImageTile>	<optional>		Class used to instantiate image tiles. Default is module:ol/ImageTile~ImageTile.
tileGrid	module:ol/tilegrid/TileGrid~TileGrid	<optional>		Tile grid.
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; };
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.
tileUrlFunction	module:ol/Tile~UrlFunction	<optional>		Optional function to get tile URL given a tile coordinate and the projection.
url	string	<optional>		URL template. Must include {x}, {y} or {-y}, and {z} placeholders. A {?-?} template pattern, for example subdomain{a-f}.domain.com, may be used instead of defining each one separately in the urls option.
urls	Array.<string>	<optional>		An array of URL templates.
wrapX	boolean	<optional>		Whether to wrap the world horizontally. The default, is to request out-of-bounds tiles from the server. When set to false, only one world will be rendered. When set to true, tiles will be requested for one world only, but they will be wrapped horizontally to render multiple worlds.
transition	number	<optional>		Duration of the opacity transition for rendering. To disable the opacity transition, pass transition: 0.
key	string	<optional>		Optional tile key for proper cache fetching
zDirection	number | module:ol/array~NearestDirectionFunction	<optional>	0	Choose whether to use tiles with a higher or lower zoom level when between integer zoom levels. See module:ol/tilegrid/TileGrid~TileGrid#getZForResolution.
