TIFFReadRawTile(3TIFF)					TIFFReadRawTile(3TIFF)

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  automatiā€
       cally  does this when converting an (x,y,z,sample) coordinate 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(3TIFF) routine.
