      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)
      Specified by:
      getTileHeight in interface ILcdRaster

    • clearCache

      public void clearCache()

    • getTile

      public ALcdBasicImage getTile(long aTileX, long aTileY)
      Description copied from class: ALcdImageMosaic
      Returns a single tile from this image. May return null if no data is available. If the supplied sampling parameters allow it, however, the image may also create a new tile by extrapolating data from other levels of detail.

      Note that this method may require costly IO. Even if data is loaded lazily then some IO may still be required to determine if the tile exists or not. So typically this method should not be invoked from the paint thread. Also note that a mosaic may contain many tiles (ex. millions) so iterating over all tiles may take a very long time.

      Specified by:
      getTile in class ALcdImageMosaic
      Parameters:
      aTileX - the tile x coordinate in [0, getConfiguration().getColumnCount()[
      aTileY - the tile y coordinate in [0, getConfiguration().getRowCount()[
      Returns:
      the tile or null

    • getConfiguration

      public ALcdImageMosaic.Configuration getConfiguration()
      Description copied from class: ALcdImageMosaic
      Returns an image configuration object describing the properties of this image mosaic's data.
      Specified by:
      getConfiguration in class ALcdImageMosaic
      Returns:
      the image's configuration
