<H2>DESCRIPTION</H2>

The following routines are used by the library to swap
16- and 32-bit data and to reverse the order of bits in bytes.
<P>

<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.
<P>

<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>.
