Provided by: libtiff5-dev_4.0.9-5ubuntu0.10_amd64 bug

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  automatically 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.
