</div>Yes that code should work from python console in qgis or within a<br>
plugin. You can also make it working from outside of qgis application<br>
as a command line tool, you will just have to do some bootstrapping:<br>
initialize qgis libraries (QgsApplication: setPrefixPath, initQgis),<br>
load some layers, construct and set up a map renderer<br>
(QgsMapRenderer). The example code omits that for simplicity and uses<br>
map renderer from canvas.<br>

<br>
</div>This is indeed possible - one just has to initialize all the machinery<br>
as briefly described above.<br>
