<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> | |
