NAME
       TIFFReadRawTile - return an undecoded tile of data from an
       open TIFF file

SYNOPSIS
       #include <tiffio.h>
       tsize_t TIFFReadRawTile(TIFF* tif, ttile_t  tile,  tdata_t
       buf, tsize_t size)

DESCRIPTION
       Read  the  contents  of	the specified tile into the (user
       supplied) data buffer.  Note that the value of tile  is	a
       ``raw  tile  number.''  That is, the caller must take into
       account whether or not the data is organized  in	 separate
       planes (PlanarConfiguration=2).	TIFFComputeTile automati
       cally does this when converting an (x,y,z,sample)  coordi
       nate  quadruple	to a tile number.  To read a full tile of
       data the data buffer should typically be at least as large
       as the value returned by TIFFTileSize.

RETURN VALUES
       The actual number of bytes of data that were placed in buf
       is returned; TIFFReadEncodedTile returns -1  if	an  error
       was encountered.

DIAGNOSTICS
       All  error messages are directed to the TIFFError(3T) rou
       tine.
