    • init

      public void init(SegmentHeader header, SubInputStream sis) throws InvalidHeaderValueException, IntegerMaxValueException, IOException
      Description copied from interface: SegmentData
      Parse the stream and read information of header.
      Specified by:
      init in interface SegmentData
      Parameters:
      header - - The segments' header (to make referred-to segments available in data part).
      sis - - Wrapped ImageInputStream into SubInputStream.
      Throws:
      InvalidHeaderValueException - if the segment header value is invalid
      IntegerMaxValueException - if the maximum value limit of an integer is exceeded
      IOException - if an underlying IO operation fails
