       The following routines return status information about an open TIFF file.

       TIFFCurrentDirectory  returns the index of the current directory (directories are numbered starting at 0). This
       number is suitable for use with the TIFFSetDirectory routine.

       TIFFLastDirectory returns a non-zero value if the current directory is the last directory in the  file;  other-
       wise zero is returned.

       TIFFCurrentRow,  TIFFCurrentStrip,  and TIFFCurrentTile, return the current row, strip, and tile, respectively,
       that is being read or written. These values are updated each time a read or write is done.

       TIFFFileno returns the underlying file descriptor used to access the TIFF image in the filesystem.

       TIFFFileName returns the pathname argument passed to TIFFOpen or TIFFFdOpen.

       TIFFGetMode returns the mode with which the underlying file was opened. On UNIX  systems,  this  is  the  value
       passed to the open(2) system call.

       TIFFIsTiled  returns a non-zero value if the image data has a tiled organization. Zero is returned if the image
       data is organized in strips.

       TIFFIsByteSwapped returns a non-zero value if the image data was  in  a  different  byte-order  than  the  host
       machine.  Zero is returned if the TIFF file and local host byte-orders are the same.  Note that TIFFReadTile(),
       TIFFReadStrip() and TIFFReadScanline() functions already normally perform byte swapping to local host order  if

       TIFFIsUpSampled  returns  a  non-zero value if image data returned through the read interface routines is being
       up-sampled. This can be useful to applications that want to calculate I/O buffer sizes to  reflect  this  usage
       (though the usual strip and tile size routines already do this).

       TIFFIsMSB2LSB  returns  a non-zero value if the image data is being returned with bit 0 as the most significant

       TIFFGetVersion returns an ASCII string that has a version stamp for the TIFF library software.
