NAME

       cols="2" cellspacing="0" cellpadding="0">

TIFFSetDirectory, TIFFSetSubDirectory − set the

current directory for an open <small>TIFF</small> file

SYNOPSIS

       cols="2" cellspacing="0" cellpadding="0">

#include <tiffio.h>

int TIFFSetDirectory(TIFF *tif,

tdir_t dirnum)

int TIFFSetSubDirectory(TIFF *tif, uint32

diroff)

DESCRIPTION

       cols="2" cellspacing="0" cellpadding="0">

TIFFSetDirectory changes the current directory and

reads its contents with TIFFReadDirectory. The

parameter dirnum specifies the subfile/directory as

an integer number, with the first directory numbered

zero.

TIFFSetSubDirectory acts like

TIFFSetDirectory, except the directory is specified

as a file offset instead of an index; this is required for

accessing subdirectories linked through a SubIFD

tag.

RETURN VALUES

       cols="2" cellspacing="0" cellpadding="0">

On successful return 1 is returned. Otherwise, 0 is

returned if dirnum or diroff specifies a

non-existent directory, or if an error was encountered while

reading the directory’s contents.

DIAGNOSTICS

       cols="2" cellspacing="0" cellpadding="0">

All error messages are directed to the

TIFFError(3TIFF) routine.

%s: Error fetching directory count. An error was

encountered while reading the ‘‘directory

count’’ field.

%s: Error fetching directory link. An error was

encountered while reading the ‘‘link

value’’ that points to the next directory in a

file.
