<p><i>TIFFSetDirectory</i> changes the current directory and |
|
57 |
reads its contents with <i>TIFFReadDirectory</i>. The |
|
58 |
parameter <i>dirnum</i> specifies the subfile/directory as |
|
59 |
an integer number, with the first directory numbered |
|
60 |
zero.</p> |
|
61 |
<!-- INDENTATION --> |
|
62 |
<p><i>TIFFSetSubDirectory</i> acts like |
|
63 |
<i>TIFFSetDirectory</i>, except the directory is specified |
|
64 |
as a file offset instead of an index; this is required for |
|
65 |
accessing subdirectories linked through a <i>SubIFD</i> |
|
66 |
tag.</p> |
