NAME

       TIFFGetBitRevTable,  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 TIFFSwabArrayOfLong 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.
