Type Definitions

Options{Object}

Properties:

Name	Type	Argument	Default	Description
extent	module:ol/extent~Extent	<optional>		Extent for the tile grid. No tiles outside this extent will be requested by module:ol/source/Tile sources. When no origin or origins are configured, the origin will be set to the top-left corner of the extent.
minZoom	number	<optional>	0	Minimum zoom.
origin	module:ol/coordinate~Coordinate	<optional>		The tile grid origin, i.e. where the x and y axes meet ([z, 0, 0]). Tile coordinates increase left to right and upwards. If not specified, extent or origins must be provided.
origins	Array.<module:ol/coordinate~Coordinate>	<optional>		Tile grid origins, i.e. where the x and y axes meet ([z, 0, 0]), for each zoom level. If given, the array length should match the length of the resolutions array, i.e. each resolution can have a different origin. Tile coordinates increase left to right and upwards. If not specified, extent or origin must be provided.
resolutions	Array.<number>			Resolutions. The array index of each resolution needs to match the zoom level. This means that even if a minZoom is configured, the resolutions array will have a length of maxZoom + 1.
sizes	Array.<module:ol/size~Size>	<optional>		Sizes.
tileSize	number | module:ol/size~Size	<optional>		Tile size. Default is [256, 256].
tileSizes	Array.<module:ol/size~Size>	<optional>		Tile sizes. If given, the array length should match the length of the resolutions array, i.e. each resolution can have a different tile size.
