| | 62 | <p>The following routines are used by the library to swap |
| | 63 | 16- and 32-bit data and to reverse the order of bits in |
| | 64 | bytes.</p> |
| | 65 | <!-- INDENTATION --> |
| | 66 | <p><i>TIFFSwabShort</i> and <i>TIFFSwabLong</i> swap the |
| | 67 | bytes in a single 16-bit and 32-bit item, respectively. |
| | 68 | <i>TIFFSwabArrayOfShort</i> and <i>TIFFSwabArrayOfLong</i> |
| | 69 | swap the bytes in an array of 16-bit and 32-bit items, |
| | 70 | respectively.</p> |
| | 71 | <!-- INDENTATION --> |
| | 72 | <p><i>TIFFReverseBits</i> replaces each byte in <i>data</i> |
| | 73 | with the equivalent bit-reversed value. This operation is |
| | 74 | performed with a lookup table, which is returned using the |
| | 75 | <i>TIFFGetBitRevTable</i> function. <i>reversed</i> |
| | 76 | parameter specifies which table should be returned. Supply |
| | 77 | <i>1</i> if you want bit reversal table. Supply <i>0</i> to |
| | 78 | get the table that do not reverse bit values. It is a lookup |
| | 79 | table that can be used as an <i>identity function</i>; i.e. |
| | 80 | <i>TIFFNoBitRevTable[n] == n</i>.</p> |
