Class MercatorTileImage

  • All Implemented Interfaces:
    CoordinateTransformer 

    public class MercatorTileImage
extends Object
implements CoordinateTransformer
    An image tile that shows a part of the world using Mercator projection. The MercatorTileImage implements the CoordinateTransformer interface and thereby transforms lon/lat coordinates to pixel coordinates on the image.
