DESCRIPTION
       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 rou-
       tine.

       TIFFLastDirectory returns a non-zero value if the  current
       directory  is  the  last  directory in the file; otherwise
       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 image data and local host byte-
       orders are the same.  Data samples that are  more  than  8
       bits wide must be byte-swapped by the application.

       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  bit.

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

DIAGNOSTICS
       None.
