NAME
       TIFFGetBitRevTable,  TIFFReverseBits,  TIFFSwabShort, TIFFSwabLong, TIFFSwabArrayOfShort, TIFFSwabArrayOfLong - byte- and bit-swapping rou-
       tines

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 performed with a lookup table, which
       is returned using the TIFFGetBitRevTable function.  reversed parameter specifies which table should be returned. Supply 1 if you  want  bit
       reversal  table.  Supply  0 to get the table that do not reverse bit values. It is a lookup table that can be used as an identity function;
       i.e.  TIFFNoBitRevTable[n] == n.

DIAGNOSTICS
       None.
