You can directly use QgsMapRenderer class to render the map to
whatever target - in your case it would be a QImage that you can save
to a file. PyQGIS cookbook gives an example how to construct and use
map renderer. If you are going to use map canvas contents you may take
advantage of map renderer from map canvas (
qgis.utils.iface.mapCanvas().mapRenderer() ) and only change extents
and trigger the rendering.
