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.
