Re: [Qgis-developer] destinationSrsChanged, custom srs

Hi Martin, QgsMapSettings is a data only object, meaning that new map settings objects are created from a map canvas "snapshot" for every rendering job and therefore they don't change and don't need to (and cannot) emit signals. That also means: map canvas is the one who manages CRS information

[Qgis-developer] destinationSrsChanged, custom srs

Hi all, when working with students on new QGIS plugin some questions raised. First we use destinationSrsChanged signal from QgsMapRender (which is DEPRECATED). We couldn't find similar signal in QgsMapSettings class. In the code we also transform coordinates using QgsCoordinateTransform class.
