Properties:
Name Type Description
attributions AttributionLike | undefined

Attributions.

cacheSize number | undefined

Initial tile cache size. Will auto-grow to hold at least the number of tiles in the viewport.

crossOrigin null | string
(defaults to 'anonymous')

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.

interpolate boolean
(defaults to true)

Use interpolated values when resampling. By default, linear interpolation is used when resampling. Set to false to use the nearest neighbor instead.

maxZoom number
(defaults to 19)

Max zoom.

opaque boolean
(defaults to true)

Whether the layer is opaque.

reprojectionErrorThreshold number
(defaults to 0.5)

Maximum allowed reprojection error (in pixels). Higher values can increase reprojection performance, but decrease precision.

tileLoadFunction LoadFunction | undefined

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

function(imageTile, src) {
  imageTile.getImage().src = src;
};
transition number
(defaults to 250)

Duration of the opacity transition for rendering. To disable the opacity transition, pass transition: 0.

url string
(defaults to 'https://tile.openstreetmap.org/{z}/{x}/{y}.png')

URL template. Must include {x}, {y} or {-y}, and {z} placeholders.

wrapX boolean
(defaults to true)

Whether to wrap the world horizontally.

zDirection number | NearestDirectionFunction
(defaults to 0)

Choose whether to use tiles with a higher or lower zoom level when between integer zoom levels. See getZForResolution.
