TIFFReverseBits,  TIFFSwabShort, TIFFSwabLong, TIFFSwabAr­
       rayOfShort, 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.   TIFFSwabArrayOf­
       Short  and  TIFFSwabArrayOfLong swap the bytes in an array
       of 16-bit and 32-bit items, respectively.

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


DIAGNOSTICS

       None.
