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 buf-
       fer 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) routine.
