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, uint32 diroff)
14

DESCRIPTION

16       TIFFSetDirectory changes the current directory and reads  its  contents
17       with  TIFFReadDirectory.   The  parameter  dirnum  specifies  the  sub‐
18       file/directory as an integer number, with the first directory  numbered
19       zero.
20
21       TIFFSetSubDirectory acts like TIFFSetDirectory, except the directory is
22       specified as a file offset instead of an index; this  is  required  for
23       accessing subdirectories linked through a SubIFD tag.
24

RETURN VALUES

26       On  successful return 1 is returned. Otherwise, 0 is returned if dirnum
27       or diroff specifies a  non-existent  directory,  or  if  an  error  was
28       encountered while reading the directory's contents.
29

DIAGNOSTICS

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