NAME

6       TIFFSetDirectory,  TIFFSetSubDirectory  - set the current directory for
7       an open TIFF file
8

SYNOPSIS

10       #include <tiffio.h>
11
12       int TIFFSetDirectory(TIFF *tif, tdir_t dirnum)
13       int TIFFSetSubDirectory(TIFF *tif, uint64_t diroff)
14

DESCRIPTION

16       TIFFSetDirectory changes the current directory and reads  its  contents
17       with TIFFReadDirectory.  The parameter dirnum specifies the subfile/di‐
18       rectory as an integer number, with the first directory numbered zero.
19
20       TIFFSetSubDirectory acts like TIFFSetDirectory, except the directory is
21       specified  as  a  file offset instead of an index; this is required for
22       accessing subdirectories linked through a SubIFD tag.
23

RETURN VALUES

25       On successful return 1 is returned. Otherwise, 0 is returned if  dirnum
26       or  diroff  specifies  a non-existent directory, or if an error was en‐
27       countered while reading the directory's contents.
28

DIAGNOSTICS

30       All error messages are directed to the TIFFError(3TIFF) routine.
31
32       %s: Error fetching directory count.  An  error  was  encountered  while
33       reading the ``directory count'' field.
34
35       %s:  Error  fetching  directory  link.   An error was encountered while
36       reading the ``link value'' that points to the next directory in a file.
