<DL>
<DD>Constructs a TIFFDirectory from a SeekableStream.
 The directory parameter specifies which directory to read from
 the linked list present in the stream; directory 0 is normally
 read but it is possible to store multiple images in a single
 TIFF file by maintaining multiple directories.
<P>
<DL>
<DT><B>Parameters:</B><DD><CODE>stream</CODE> - a SeekableStream to read from.<DD><CODE>directory</CODE> - the index of the directory to read.
<DT><B>Throws:</B>

<DL>
<DD>Constructs a TIFFDirectory by reading a SeekableStream.
 The ifd_offset parameter specifies the stream offset from which
 to begin reading; this mechanism is sometimes used to store
 private IFDs within a TIFF file that are not part of the normal
 sequence of IFDs.
<P>
<DL>
<DT><B>Parameters:</B><DD><CODE>stream</CODE> - a SeekableStream to read from.<DD><CODE>ifd_offset</CODE> - the long byte offset of the directory.<DD><CODE>directory</CODE> - the index of the directory to read beyond the
        one at the current stream offset; zero indicates the IFD
        at the current offset.
