This number is suitable for use with the <i>TIFFSetDirectory</i> routine.</p> <!-- INDENTATION --> <p><i>TIFFLastDirectory</i> returns a non-zero value if the current directory is the last directory in the file; otherwise zero is returned.</p> <!-- INDENTATION --> <p><i>TIFFCurrentRow</i>, <i>TIFFCurrentStrip</i>, and <i>TIFFCurrentTile</i>, return the current row, strip, and tile, respectively, that is being read or written. These values are updated each time a read or write is done.</p> <!-- INDENTATION --> <p><i>TIFFFileno</i> returns the underlying file descriptor used to access the <small>TIFF</small> image in the filesystem.</p> <!-- INDENTATION --> <p><i>TIFFFileName</i> returns the pathname argument passed to <i>TIFFOpen</i> or <i>TIFFFdOpen</i>.</p> <!-- INDENTATION --> <p><i>TIFFGetMode</i> returns the mode with which the underlying file was opened. On <small>UNIX</small> systems, this is the value passed to the <i>open</i>(2) system call.</p> <!-- INDENTATION --> <p><i>TIFFIsTiled</i> returns a non-zero value if the image data has a tiled organization. Zero is returned if the image data is organized in strips.</p> <!-- INDENTATION --> <p><i>TIFFIsByteSwapped</i> returns a non-zero value if the image data was in a different byte-order than the host machine. Zero is returned if the TIFF file and local host byte-orders are the same. Note that TIFFReadTile(), TIFFReadStrip() and TIFFReadScanline() functions already normally perform byte swapping to local host order if needed.</p> <!-- INDENTATION --> <p><i>TIFFIsUpSampled</i> returns a non-zero value if image data returned through the read interface routines is being up-sampled. This can be useful to applications that want to calculate I/O buffer sizes to reflect this usage (though the usual strip and tile size routines already do this).</p> <!-- INDENTATION --> <p><i>TIFFIsMSB2LSB</i> returns a non-zero value if the image data is being returned with bit 0 as the most significant bit.</p> <!-- INDENTATION --> <p><i>TIFFGetVersion</i> returns an <small>ASCII</small> string that has a version stamp for the <small>TIFF</small> library software.</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>None.</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><i>libtiff</i>(3TIFF), <i>TIFFOpen</i>(3TIFF), <i>TIFFFdOpen</i>(3TIFF)</p> </td> </table> <hr> </body> </html>
