<p>The value of <i>tile</i> is a &lsquo;&lsquo;raw tile
number.&rsquo;&rsquo; That is, the caller must take into
account whether or not the data are 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
be at least as large as the value returned by
<i>TIFFTileSize</i>.</p>
<!-- INDENTATION -->
<p>The library attempts to hide bit- and byte-ordering
differences between the image and the native machine by
converting data to the native machine order. Bit reversal is
done if the <i>FillOrder</i> tag is opposite to the native
machine bit order. 16- and 32-bit samples are automatically
byte-swapped if the file was written with a byte order
opposite to the native machine byte order,</p>
