setPrefetchZoomDelta

abstract fun setPrefetchZoomDelta(delta: Byte)

When loading a map, if prefetch zoom `delta` is set to any number greater than 0, the map will first request a tile at zoom level lower than `zoom - delta`, with requested zoom level a multiple of `delta`, in an attempt to display a full map at lower resolution as quick as possible.

Parameters

delta

The new prefetch zoom delta.
