[Qgis-user] coordinate system of a raster layer

[Peter Ersts]

 Hi Stefanie,

Are you just trying to define a coordinate system or are you trying to 
change one? It kind of sounds like you are actually trying to reproject 
your raster layer on the fly which is not currently supported.

Right now QGIS is heavily reliant on GDAL for most of the raster 
capabilities and all of the functionality in QgsRasterLayer except the 
pyramid building is read only.
