Thanks. Yes, they are there. The problem is I cannot find a way to get to
the QgisHillshadeRenderer itself, from the QgsRasterLayer.
QgsRasterLayer.renderer() only provides QgsRasterRenderer. Anyways, the
.writeXML approach works well enough. [ It is a bit strange that the
altitude is named angle as an xml attribute. ]
Ideally, I would want to get the lightAzimuth and lightAltitude values from
the hillshaderendererwidget used in the layer properties gui . Is there a
way to get that from a processing python script (or plugin)? The idea is to
use existing values provided in the nice existing GUIs as much as possible.
