TIFFSetDirectory, TIFFSetSubDirectory − set the current directory for an open TIFF file
#include
<tiffio.h>
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 directory, or if an error was encountered while reading the directory’s contents.
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.
