directory for an open TIFF file
int TIFFSetDirectory(TIFF* tif, tdir_t dirnum)
int TIFFSetSubDirectory(TIFF* tif, uint32 diroff)
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.
On successful return 1 is returned. Otherwise, 0 is
returned if dirnum or diroff specifies a non-existent direc-
tory, or if an error was encountered while reading the

tered 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
