It looks like something is wrong with the Python bindings there. In render() method there is optional second parameter "forceWidthScale" which is interpreted incorrectly and it seems to override the DPI settings. Even if I add /In/ annotation to it, there are still some issues. It seems it has been broken like this probably for long time. If you want to do map rendering with different DPI settings I would suggest one of these options: - use QgsMapSettings / QgsMapRendererJob - if you target 2.4 and above - use map composer Regards Martin _______________________________________________ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
