  • Method Details

    • createTileOperation

      OPERATION createTileOperation(int tileIndex, TileArea area)
      Creates a new instance of the supported parallel tile operation for a specifictile
      Parameters:
      tileIndex - the sequential index of the tile
      area - the location and size of the tile in the full image
      Returns:
      a new parallel operation for processing the particular 2D image tile.

    • init

      void init(OPERATION tileOperation)
      Initializes the parallel tile operation before it can be executed. For example to set particular options / parameters for the processing.
      Parameters:
      tileOperation - the parallel operation that processes a specific 2D image tile.

    • tileCount

      void tileCount(int tileCount) throws FitsException
      Sets the total number of 2D image tiles to be processed.
      Parameters:
      tileCount - the total number of image tiles to be
      Throws:
      FitsException - if the operation cannot support the desired number of tiles, for example because data stored in a FITS file is for fewer tiles.
