NAME
       TIFFReverseBits, TIFFSwabShort, TIFFSwabLong, TIFFSwabArrayOfShort, TIFFSwabArrayOfLong - byte- and bit-swapping routines

SYNOPSIS
       #include <tiffio.h>
       const unsigned char* TIFFGetBitRevTable(int reversed);
       void TIFFReverseBits(u_char* data, unsigned long nbytes)
       void TIFFSwabShort(uint16* data)
       void TIFFSwabLong(uint32* data)
       void TIFFSwabArrayOfShort(uint16* data, unsigned long nshorts)
       void TIFFSwabArrayOfLong(uint32* data, unsigned long nlongs)

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

       TIFFSwabShort  and TIFFSwabLong swap the bytes in a single 16-bit and 32-bit item, respectively.  TIFFSwabArrayOfShort and TIFFSwabArrayOf-
       Long swap the bytes in an array of 16-bit and 32-bit items, respectively.

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

DIAGNOSTICS
       None.
