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.</big></p> <!-- INDENTATION --> <p><big>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,</big></p> </td> </table> <a name="RETURN VALUES"></a> <h2>RETURN VALUES</h2> <!-- INDENTATION --> <table width="100%" border=0 rules="none" frame="void" cols="2" cellspacing="0" cellpadding="0"> <tr valign="top" align="left"> <td width="8%"></td> <td width="91%"> <p><big>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.</big></p> </td> </table> <a name="DIAGNOSTICS"></a> <h2>DIAGNOSTICS</h2> <!-- INDENTATION --> <table width="100%" border=0 rules="none" frame="void" cols="2" cellspacing="0" cellpadding="0"> <tr valign="top" align="left"> <td width="8%"></td> <td width="91%"> <p><big>All error messages are directed to the <b>TIFFError</b>(3TIFF) routine.</big></p> </td> </table> <a name="SEE ALSO"></a> <h2>SEE ALSO</h2> <!-- INDENTATION --> <table width="100%" border=0 rules="none" frame="void" cols="2" cellspacing="0" cellpadding="0"> <tr valign="top" align="left"> <td width="8%"></td> <td width="91%"> <p><big><b>TIFFOpen</b>(3TIFF), <b>TIFFReadRawStrip</b>(3TIFF), <b>TIFFReadScanline</b>(3TIFF), <b>libtiff</b>(3TIFF)</big></p> <!-- INDENTATION --> <p><big>Libtiff library home page: <b>http://www.remotesensing.org/libtiff/</b></big></p> </td> </table> <hr> </body> </html>
