NAME
TIFFSetDirectory, TIFFSetSubDirectory - set the current directory for an open
TIFF
file
SYNOPSIS
#include <tiffio.h>
int TIFFSetDirectory(TIFF* tif, tdir_t dirnum)
int TIFFSetSubDirectory(TIFF* tif, uint32 diroff)
DESCRIPTION
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
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
All error messages are directed to the
TIFFError(3T)
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.
