    • filePos

      public int filePos
      Position in file

    • isFullyRead

      public boolean isFullyRead
      Flag to say image has been read fully. It's quite possible that there is a file catalogue which just has the basic info (time and device id) without the full image and bearing table data to save on memory.

      public double[] bearingTable
      Bearing table

    • imageData

      protected byte[] imageData
      Uncompressed image data.
