+.TH TIFFReadRawTile 3T "October 15, 1995"
+.SH NAME
+TIFFReadRawTile \- return an undecoded tile of data from an open
+.SM TIFF
+file
+.SH SYNOPSIS
+.B "#include <tiffio.h>"
+.br
+.B "tsize_t TIFFReadRawTile(TIFF* tif, ttile_t tile, tdata_t buf, tsize_t size)"
+.SH DESCRIPTION
+Read the contents of the specified tile into the
+(user supplied) data buffer.
+Note that the value of
+.I tile
+is a ``raw tile number.''
+That is, the caller must take into account whether or not the
+data is organized in separate planes (\c
+.IR PlanarConfiguration =2).
+.I 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
+.IR TIFFTileSize .
+.SH "RETURN VALUES"
+The actual number of bytes of data that were placed in
+.I buf
+is returned;
+.IR TIFFReadEncodedTile
+returns \-1 if an error was encountered.
+.SH DIAGNOSTICS
+All error messages are directed to the
+.IR TIFFError (3T)
+routine.
+.SH "SEE ALSO"

+.IR TIFFOpen (3T),
