TIFFReadRawTile(3tiff)					 Introduction to Library Functions				    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.

       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 num-
       ber. To read a full tile of data, the data buffer should typically be at least as large as the value returned by TIFFTileSize(3tiff).

       All error messages are directed to the TIFFError(3tiff) routine.

RETURN VALUES
       Returns the actual number of bytes of data that were placed in buf. Returns -1 if an error was encountered.
