Attributions.

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>
'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 <optional>
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 <optional>
19

Max zoom.

opaque boolean <optional>
true

Whether the layer is opaque.

reprojectionErrorThreshold number <optional>
0.5

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

tileLoadFunction LoadFunction <optional>

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

function(imageTile, src) {
  imageTile.getImage().src = src;
};
transition number <optional>
250

true

Whether to wrap the world horizontally.

zDirection number | NearestDirectionFunction <optional>
