    • createBand

      Band createBand(int dataType, int rows, int columns, NoData noData, PageManager pageManager) throws BandException
      Creates a Band. If PageManager is null, the band will be in memory, otherwise, the band will be paginated using page manager.
      Parameters:
      dataType - Type of band. Check BufferManager to see what types are available
      rows - Band rows
      columns - Band columns
      noData - NoData of band. If It is null, a undefined NoData will be set.
      pageManager - Page manager to paginate band. It page manager is null, band will be in memory.
      Returns:
      Band A empty band.
      Throws:
      BandException - If there are problems creating the band.
