67<p>The following routines return status information about an
68open <small>TIFF</small> file.</p>
69<!-- INDENTATION -->
70<p><i>TIFFCurrentDirectory</i> returns the index of the
71current directory (directories are numbered starting at 0).
72This number is suitable for use with the
73<i>TIFFSetDirectory</i> routine.</p>
74<!-- INDENTATION -->
75<p><i>TIFFLastDirectory</i> returns a non-zero value if the
76current directory is the last directory in the file;
77otherwise zero is returned.</p>
78<!-- INDENTATION -->
79<p><i>TIFFCurrentRow</i>, <i>TIFFCurrentStrip</i>, and
80<i>TIFFCurrentTile</i>, return the current row, strip, and
81tile, respectively, that is being read or written. These
82values are updated each time a read or write is done.</p>
83<!-- INDENTATION -->
84<p><i>TIFFFileno</i> returns the underlying file descriptor
85used to access the <small>TIFF</small> image in the
86filesystem.</p>
87<!-- INDENTATION -->
88<p><i>TIFFFileName</i> returns the pathname argument passed
89to <i>TIFFOpen</i> or <i>TIFFFdOpen</i>.</p>
90<!-- INDENTATION -->
91<p><i>TIFFGetMode</i> returns the mode with which the
92underlying file was opened. On <small>UNIX</small> systems,
93this is the value passed to the <i>open</i>(2) system
94call.</p>
95<!-- INDENTATION -->
96<p><i>TIFFIsTiled</i> returns a non-zero value if the image
97data has a tiled organization. Zero is returned if the image
98data is organized in strips.</p>
99<!-- INDENTATION -->
100<p><i>TIFFIsByteSwapped</i> returns a non-zero value if the
101image data was in a different byte-order than the host
102machine. Zero is returned if the TIFF file and local host
103byte-orders are the same. Note that TIFFReadTile(),
104TIFFReadStrip() and TIFFReadScanline() functions already
105normally perform byte swapping to local host order if
106needed.</p>
107<!-- INDENTATION -->
108<p><i>TIFFIsUpSampled</i> returns a non-zero value if image
109data returned through the read interface routines is being
110up-sampled. This can be useful to applications that want to
111calculate I/O buffer sizes to reflect this usage (though the
112usual strip and tile size routines already do this).</p>
113<!-- INDENTATION -->
114<p><i>TIFFIsMSB2LSB</i> returns a non-zero value if the
115image data is being returned with bit 0 as the most
116significant bit.</p>
117<!-- INDENTATION -->
118<p><i>TIFFGetVersion</i> returns an <small>ASCII</small>
119string that has a version stamp for the <small>TIFF</small>
120library software.</p>
