<h2>DESCRIPTION</h2>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em">The following
|
|
routines return status information about an open
|
|
<small>TIFF</small> file.</p>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em"><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>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em"><i>TIFFLastDirectory</i>
|
|
returns a non-zero value if the current directory is the
|
|
last directory in the file; otherwise zero is returned.</p>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em"><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>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em"><i>TIFFFileno</i>
|
|
returns the underlying file descriptor used to access the
|
|
<small>TIFF</small> image in the filesystem.</p>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em"><i>TIFFFileName</i>
|
|
returns the pathname argument passed to <i>TIFFOpen</i> or
|
|
<i>TIFFFdOpen</i>.</p>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em"><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>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em"><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>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em"><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>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em"><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>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em"><i>TIFFIsMSB2LSB</i>
|
|
returns a non-zero value if the image data is being returned
|
|
with bit 0 as the most significant bit.</p>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em"><i>TIFFGetVersion</i>
|
|
returns an <small>ASCII</small> string that has a version
|
|
stamp for the <small>TIFF</small> library software.</p>
