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.
