                  int directory)
           throws IOException
        Constructs a XTIFFImage that acquires its data from a given SeekableStream and reads from a particular IFD of the stream. The index of the first IFD is 0.
        Parameters:
        stream - the SeekableStream to read from.
        param - an instance of TIFFDecodeParam, or null.
        directory - the index of the IFD to read from.
        Throws:
        IOException
