SWAB(3TIFF) SWAB(3TIFF) 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.

TIFFswab, TIFFGetBitRevTable, TIFFReverseBits, TIFFSwabShort, TIFFSwabLong, TIFFSwabArrayOfShort, TIFFSwabArrayOfLong - byte- and bit-swap- ping 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) The following routines are used by the library to swap 16- and 32-bit data and to reverse the order of bits in bytes.

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 done with a lookup table, TIFFBi- tRevTable, which is declared public. A second table, TIFFNoBitRevTable, is also declared public, and is a lookup table that can be used as an identity function. That is, TIFFNoBitRevTable[n] == n.
