<p><i>TIFFSetDirectory</i> changes the current directory and
reads its contents with <i>TIFFReadDirectory</i>. The
parameter <i>dirnum</i> specifies the subfile/directory as
an integer number, with the first directory numbered
zero.</p>
<!-- INDENTATION -->
<p><i>TIFFSetSubDirectory</i> acts like
<i>TIFFSetDirectory</i>, except the directory is specified
as a file offset instead of an index; this is required for
accessing subdirectories linked through a <i>SubIFD</i>
tag.</p>
