| 70 | <p><big>The value of <i>strip</i> is a ‘‘raw | |
| 71 | strip number.’’ That is, the caller must take | |
| 72 | into account whether or not the data are organized in | |
| 73 | separate planes (<i>PlanarConfiguration</i>=2). To read a | |
| 74 | full strip of data the data buffer should typically be at | |
| 75 | least as large as the number returned by | |
| 76 | <b>TIFFStripSize</b>(3TIFF). If the -1 passed in <i>size</i> | |
| 77 | parameter, the whole strip will be read. You should be sure | |
| 78 | you have enough space allocated for the buffer.</big></p> | |
| 79 | <!-- INDENTATION --> | |
| 80 | <p><big>The library attempts to hide bit- and byte-ordering | |
| 81 | differences between the image and the native machine by | |
| 82 | converting data to the native machine order. Bit reversal is | |
| 83 | done if the <i>FillOrder</i> tag is opposite to the native | |
| 84 | machine bit order. 16- and 32-bit samples are automatically | |
| 85 | byte-swapped if the file was written with a byte order | |
| 86 | opposite to the native machine byte order,</big></p> | |
