.TH TIFFReadRawTile 3TIFF "October 15, 1995" "libtiff"
.SH NAME
TIFFReadRawTile \- return an undecoded tile of data from an open
.SM TIFF
file
.SH SYNOPSIS
.B "#include <tiffio.h>"
.sp
.BI "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
.BR TIFFError (3TIFF)
routine.
