Hmm, works for me. Maybe your layers don't contain projection information? unclear to me how to check this: the raster appears on the right place, however. Try with gdalinfo tool, if raster has projection, this tool will show it. Also raster can be displayed in correct place even it doesn't have assigned projection, but has correct wld file. Maybe this is your case.

This is true only for tools, that are command line utilities. Extract projection is exception, it uses GDAL API and has no independent command line equivalent. Also it is possible to add text field for additional command line arguments in Processing. ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
