      Note that the tiles in the last (bottom) row can be smaller then other rows. The height of the last row is: 

      
  getBounds().getHeight() - getTileHeight() * (getTileRowCount() - 1)

    • retrieveTile

      public ILcdTile retrieveTile(int aRow, int aColumn)
      Description copied from interface: ILcdRaster
      Retrieves the specified tile.
      Specified by:

      If the geometry does not allow retrieving valid bounds (for example a polyline with 0 points) the return value is unspecified. It is highly recommended to return an undefined bounds. You can create undefined bounds using the default constructors of TLcdLonLatBounds or TLcdXYBounds.

      Specified by:

      Specified by:
      insertIntoCache in interface ILcdCache
