<H2>DESCRIPTION</H2>

<I>TIFFSetDirectory</I>
|

|
||
|
|
<I>TIFFReadDirectory</I>.
|

The parameter
|
||
|
|
<I>dirnum</I>
|
||
|
|
|
||
|
|
specifies the subfile/directory as an integer number, with
|
||
|
|
the first directory numbered zero.

|
|
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>
|

||
|
