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
       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.
