<p style="margin-left:11%; margin-top: 1em">TIFFReadRawTile
− return an undecoded tile of data from an open
<small>TIFF</small> file</p>
<h2>SYNOPSIS
<a name="SYNOPSIS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><b>#include
<tiffio.h></b></p>
<p style="margin-left:11%; margin-top: 1em"><b>tsize_t

<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Read the
contents of the specified tile into the (user supplied) data
buffer. Note that the value of <i>tile</i> is a
‘‘raw tile number.’’ That is, the
caller must take into account whether or not the data is
organized in separate planes (<i>PlanarConfiguration</i>=2).
<i>TIFFComputeTile</i> 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
<i>TIFFTileSize</i>.</p>
<h2>RETURN VALUES
<a name="RETURN VALUES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The actual
number of bytes of data that were placed in <i>buf</i> is
returned; <i>TIFFReadEncodedTile</i> returns −1 if an
error was encountered.</p>
<h2>DIAGNOSTICS
<a name="DIAGNOSTICS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">All error
messages are directed to the <b>TIFFError</b>(3TIFF)
routine.</p>
