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 routine.

       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 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 needed.

       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.
