| 55 | <p>The following routines are provided for client-control of | |
| 56 | the I/O buffers used by the library. Applications need never | |
| 57 | use these routines; they are provided only for | |
| 58 | ‘‘intelligent clients’’ that wish to | |
| 59 | optimize memory usage and/or eliminate potential copy | |
| 60 | operations that can occur when working with images that have | |
| 61 | data stored without compression.</p> | |

| 63 | <p><i>TIFFReadBufferSetup</i> sets up the data buffer used | |
| 64 | to read raw (encoded) data from a file. If the specified | |
| 65 | pointer is <small>NULL</small> (zero), then a buffer of the | |
| 66 | appropriate size is allocated. Otherwise the caller must | |
| 67 | guarantee that the buffer is large enough to hold any | |
| 68 | individual strip of raw data. <i>TIFFReadBufferSetup</i> | |
| 69 | returns a non-zero value if the setup was successful and | |
| 70 | zero otherwise.</p> | |
| 71 | <!-- INDENTATION --> | |
| 72 | <p><i>TIFFWriteBufferSetup</i> sets up the data buffer used | |
| 73 | to write raw (encoded) data to a file. If the specified | |
| 74 | <i>size</i> is −1 then the buffer size is selected to | |
| 75 | hold a complete tile or strip, or at least 8 kilobytes, | |
| 76 | whichever is greater. If the specified <i>buffer</i> is | |
| 77 | <small>NULL</small> (zero), then a buffer of the appropriate | |
| 78 | size is dynamically allocated. <i>TIFFWriteBufferSetup</i> | |
| 79 | returns a non-zero value if the setup was successful and | |
| 80 | zero otherwise.</p> | |
