and 32-bit data and to reverse the order of bits in
bytes.</td></table>

<i>TIFFSwabShort</i> and <i>TIFFSwabLong</i> swap the bytes
in a single 16-bit and 32-bit item, respectively.
<i>TIFFSwabArrayOfShort</i> and <i>TIFFSwabArrayOfLong</i>
swap the bytes in an array of 16-bit and 32-bit items,
respectively.</td></table>

<i>TIFFReverseBits</i> replaces each byte in <i>data</i>
with the equivalent bit-reversed value. This operation is
done with a lookup table, <i>TIFFBitRevTable</i> which is
declared public. A second table, <i>TIFFNoBitRevTable</i> is
also declared public; it is a lookup table that can be used
as an <i>identity function</i>; i.e. <i>TIFFNoBitRevTable[n]
== n</i>.</td></table>
