- <p>The following routines return status information about an
- open <small>TIFF</small> file.</p>
- <!-- INDENTATION -->
- <p><i>TIFFCurrentDirectory</i> returns the index of the
- current directory (directories are numbered starting at 0).
- 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>
