This is a bug or a feature? Hi Sergey I would recommend not to use the distanceArea() instance from QgsMapRenderer at all. It was supposed to be a convenient instance, however it's better to construct your own QgsDistanceArea instance when doing anything with measuring. The main problem with that instance is that other code (e.g. plugin) could modify your parameters and the measuring will be wrong. Anyway that instance currently reacts only when on-the-fly projections are turned on/off and when project CRS got changed.

Hi Sergey Ticket is assigned. > mTool->canvas()->mapRenderer()->distanceArea()->ellipsoid() return always > WGS84 If maprenderer does not take the ellipsoid from settings, it's probably a bug.

[Qgis-developer] Measure tool ignore 'measure\ellipsoid' QGis settings
Hi. I'm author measure_ellipsoid.diff ( http://trac.osgeo.org/qgis/ticket/3240 ) . In file src/app/qgsmeasuredialog.cpp, line 139 mTool->canvas()->mapRenderer()->distanceArea()->ellipsoid() return always WGS84. It not depend on project coordinate systems or "measure\ellpsiod" settings. I know not good code QGIS. This is a bug or a feature? P.S. For measure tools I have a path to use 'measure\ellipsoid' ( http://trac.osgeo.org/qgis/ticket/3384 ) -- Thanks ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
