<p>This is a convenience API using D-Bus for creating and updating
thumbnails for files being mined. It is also used to create
thumbnails for album art found embedded in some medias.</p>
<p>This follows the thumbnailer specification:

tracker_thumbnailer_new (<em class="parameter"><code><span class="type">void</span></code></em>);</pre>
<p>Creates a new <a class="link" href="libtracker-miner-TrackerThumbnailer.html#TrackerThumbnailer" title="struct TrackerThumbnailer"><span class="type">TrackerThumbnailer</span></a> object that can be used to signal
the system's thumbnailing daemon(s) via D-Bus to add or remove
content that needs thumbnailing.</p>
<p>For example, when mounting a USB thumb drive, content may not have
thumbnails and this object allows the content of that thumb drive
to be queued for processing.</p>
