<p>The following routines are used by the library to swap

16- and 32-bit data and to reverse the order of bits in

|
|
|
bytes.</p>

<!-- INDENTATION -->
|
|
|
|
|
<p><i>TIFFSwabShort</i> and <i>TIFFSwabLong</i> swap the
|
|
|
|
|
bytes in a single 16-bit and 32-bit item, respectively.
|
|
|
|
|
<i>TIFFSwabArrayOfShort</i> and <i>TIFFSwabArrayOfLong</i>
|
|
|
|
|
swap the bytes in an array of 16-bit and 32-bit items,

respectively.</p>

<p><i>TIFFReverseBits</i> replaces each byte in <i>data</i>
|
|
|
|
|
with the equivalent bit-reversed value. This operation is
|
|
|
|
|
performed with a lookup table, which is returned using the
|
2005-03-06 06:11:43 -05:00
|
|
|
<i>TIFFGetBitRevTable</i> function. <i>reversed</i>

parameter specifies which table should be returned. Supply
|
|

|
<i>1</i> if you want bit reversal table. Supply <i>0</i> to

get the table that do not reverse bit values. It is a lookup

table that can be used as an <i>identity function</i>; i.e.

|
|
|
|
<i>TIFFNoBitRevTable[n] == n</i>.</p>
