Data tile loading function. The function is called with z, x, and y tile coordinates and returns data for a tile or a promise for the same.

Options{Object}

Properties:

Name	Type	Argument	Default	Description
loader	Loader	<optional>		Data loader. Called with z, x, and y tile coordinates. Returns data for a tile or a promise for the same. For loaders that generate images, the promise should not resolve until the image is loaded.
attributions	AttributionLike	<optional>		Attributions.
attributionsCollapsible	boolean	<optional>	true	Attributions are collapsible.
maxZoom	number	<optional>	42	Optional max zoom level. Not used if tileGrid is provided.
minZoom	number	<optional>	0	Optional min zoom level. Not used if tileGrid is provided.
tileSize	number | Size	<optional>	[256, 256]	The pixel width and height of the source tiles. This may be different than the rendered pixel size if a tileGrid is provided.
gutter	number	<optional>	0	The size in pixels of the gutter around data tiles to ignore. This allows artifacts of rendering at tile edges to be ignored. Supported data should be wider and taller than the tile size by a value of 2 x gutter.
maxResolution	number	<optional>		Optional tile grid resolution at level zero. Not used if tileGrid is provided.
projection	ProjectionLike	<optional>	'EPSG:3857'	Tile projection.
tileGrid	TileGrid	<optional>		Tile grid.
opaque	boolean	<optional>	false	Whether the layer is opaque.
state	State	<optional>		The source state.
wrapX	boolean	<optional>	false	Render tiles beyond the antimeridian.
transition	number	<optional>		Transition time when fading in new tiles (in miliseconds).
bandCount	number	<optional>	4	Number of bands represented in the data.
interpolate	boolean	<optional>	false	Use interpolated values when resampling. By default, the nearest neighbor is used when resampling.
