The following routines are used by the library to swap 16- and 32-bit
data and to reverse the order of bits in bytes\&.
.PP
\fBTIFFSwabShort\fR and \fBTIFFSwabLong\fR
swap the bytes in a single 16-bit and 32-bit item, respectively\&.
.PP
\fBTIFFSwabArrayOfShort\fR and \fBTIFFSwabArrayOfLong\fR swap the bytes in an array of 16-bit and 32-bit items, respectively\&.
.PP
\fBTIFFReverseBits\fR replaces each byte in data with the
equivalent bit-reversed value\&. This operation is done with a lookup table, \fBTIFFBitRevTable\fR, which is declared public\&. A second table, \fBTIFFNoBitRevTable\fR, is also declared public, and is a lookup table
that can be used as an identity function\&. That is, \fBTIFFNoBitRevTable[n]
== n\fR\&.
