<p>
<a class="link" href="GnomeScanner.html" title="GnomeScanner"><span class="type">GnomeScanner</span></a> is the base class for backend specific scanner (like
e.g SANE). Following SANE design, Gnome Scan scanner has an

acquisition.
</p>
<p>
Each <a class="link" href="GnomeScanner.html" title="GnomeScanner"><span class="type">GnomeScanner</span></a> should monitor its sensor (e.g. paper-in) and
trigger an event on sensor state changes.</p>
