LIBGEOTIFF
</title></center>

<h2>Functions</h2>

<ul>
<li> GTIFFree(): Free GeoTIFF access handle.
<li> GTIFGetDefn(): Read and Normalize GeoTIFF Definition.
<li> GTIFKeyGet(): Read GeoTIFF GeoKey.
<li> GTIFKeySet(): Write GeoTIFF GeoKey.
<li> GTIFNew(): Create GeoTIFF access handle.
<li> GTIFWriteKeys(): Flush GeoTIFF Keys.
<li> XTIFFClose(): Close GeoTIFF file.
<li> XTIFFOpen(): Open GeoTIFF file.
</ul>

<h2>General Notes</h2>

The libgeotiff library should compile cleanly with most ANSI-C or 
ANSI C++ compilers.  All headers have appropriate <b>extern "C" {}</b>
protection to ensure that entry points retain C linkage even if compiled
with a C++ compiler. <p>

<h2>Source Tree</h2>

The <a href="http://www.remotesensing.org/cgi-bin/cvsweb.cgi/osrs/geotiff">
current CVS tree</a> is available on the web.  The source can be 
downloaded anonymously using the <tt>cvs checkout osrs/geotiff/libgeotiff</tt>
command after logging in using the instructions on the remotesensing.org
<a href="/docs/howto-cvs.php3">CVS howto page</a>.<p>

<h2>Include Files</h2>

<ul>
<li> xtiffio.h: the primary interface header file for all TIFF
routines, using the extended GeoTIFF tags.<p>

<li> geotiffio.h: the primary interface header file for all GTIF 
routines, keys and code values.<p>

<li> geotiff.h: an interface header file for all GTIF 
routines, if code values are not required.<p>

<li> geokeys.h:   defines all valid GEOTIFF GeoKeys.<p>

<li> geo_normalize.h: Defined all functions and structures related
to normalization of GeoTIFF information based on PROJ database.<p>

</ul>
