Class RasterTileReader<T, P>

constructor

• new RasterTileReader<
      T extends Properties = RGBA
      | ElevationPoint,
      P extends Properties = T,
  >(
      zoom: number,
      x: number,
      y: number,
      image: ImageData,
      tmsStyle?: boolean,
      converter?: ElevationConverter,
  ): RasterTileReader<T, P>

  Type Parameters

  • T extends Properties = RGBA | ElevationPoint
  • P extends Properties = T

  Parameters

  • zoom: number

    the zoom level of the tile
  • x: number

    the x coordinate of the tile
  • y: number

    the y coordinate of the tile
  • image: ImageData

    the raw RGB(A) image data
  • tmsStyle: boolean = false

    if true, the y is inverted
  • Optionalconverter: ElevationConverter

    the elevation converter (if provided its not an RGBA image but rather elevation data)

  Returns RasterTileReader<T, P>

Optional Readonlyconverter

Readonlyimage

ReadonlytmsStyle

Readonlyx

Readonlyy

Readonlyzoom

[asyncIterator]

• "[asyncIterator]"(): AsyncGenerator<VectorFeature<TileMetadata, T, P>>

  Iterate over all tiles in the archive

  Returns AsyncGenerator<VectorFeature<TileMetadata, T, P>>

  Yields

  • the each of the tile's pixel RGBA data as lon-lat coordinates with the RGBA as m-values
