Method Detail

• getBoundingBox

  public static BBox getBoundingBox(Tile tile)

  Get the bounding box that the given tile covers.

  Parameters:

  tile - the tile to compute a bounding box for.

  Returns:

  a BBox instance.

• getBoundingBox

  public static BBox getBoundingBox(double txStart,
                                    double txEnd,
                                    double tyStart,
                                    double tyEnd,
                                    int zoom)

  Get the bounding box that is covered by the given tile coordinates. Fractional tile-numbers are possible here to allow the computation of bounding boxes across partly covered tiles.

  Parameters:

  txStart - the start of the box in fractional tile-coordinates.

  txEnd - the end of the box in fractional tile-coordinates.

  tyStart - the start of the box in fractional tile-coordinates.

  tyEnd - the end of the box in fractional tile-coordinates.

  zoom - the zoom level the tile coordinates are to be resolved on

  Returns:

  a BBox instance.

• isValid

  public static boolean isValid(Tile tile)

  Check if a tile is valid, i.e. its coordinates are within the range [0..2^zoom].

  Parameters:

  tile - the tile to check

  Returns:

  whether the specified tile is valid.

• valid

  public static <T extends Tile> Iterable<T> valid(Iterable<T> iterable)

  Create an Iterable that contains all Tiles that are valid as of isValid(Tile).
