TIFFSetDirectory 3TIFF "October 15, 1995" "libtiff"
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 ", uint64 " 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 (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.
