To read a full strip of data the data buffer should typically be at least as large as the number returned by <b>TIFFStripSize</b>(3TIFF). If the -1 passed in <i>size</i> parameter, the whole strip will be read. You should be sure you have enough space allocated for the buffer.</p> <p style="margin-left:11%; margin-top: 1em">The library attempts to hide bit- and byte-ordering differences between the image and the native machine by converting data to the native machine order. Bit reversal is done if the <i>FillOrder</i> tag is opposite to the native machine bit order. 16- and 32-bit samples are automatically byte-swapped if the file was written with a byte order opposite to the native machine byte order,</p> <h2>RETURN VALUES <a name="RETURN VALUES"></a> </h2> <p style="margin-left:11%; margin-top: 1em">The actual number of bytes of data that were placed in <i>buf</i> is returned; <i>TIFFReadEncodedStrip</i> returns −1 if an error was encountered.</p> <h2>DIAGNOSTICS <a name="DIAGNOSTICS"></a> </h2> <p style="margin-left:11%; margin-top: 1em">All error messages are directed to the <b>TIFFError</b>(3TIFF) routine.</p> <h2>SEE ALSO <a name="SEE ALSO"></a> </h2> <p style="margin-left:11%; margin-top: 1em"><b>TIFFOpen</b>(3TIFF), <b>TIFFReadRawStrip</b>(3TIFF), <b>TIFFReadScanline</b>(3TIFF), <b>libtiff</b>(3TIFF)</p> <p style="margin-left:11%; margin-top: 1em">Libtiff library home page: <b>http://www.simplesystems.org/libtiff/</b></p> <hr> </body> </html>
