<para><literal>TIFFSetDirectory</literal> changes the current directory and

reads the directory contents with <literal>TIFFReadDirectory</literal>. The

parameter <literal>dirnum</literal> specifies the subfile/directory as an

integer number, with the first directory numbered zero.</para>

<para><literal>TIFFSetSubDirectory</literal> acts like <literal>TIFFSetDirectory

</literal>, except that the directory is specified as a file offset instead

of an index. This is required for accessing subdirectories linked through

a <literal>SubIFD</literal> tag.</para>
