Merge and invert features (polygons only)
static QgsMergedFeatureRenderer * convertFromRenderer(const QgsFeatureRenderer *renderer)
Creates a QgsMergedFeatureRenderer by a conversion from an existing renderer.
QgsMergedFeatureRenderer * clone() const override
Create a deep copy of this renderer.
The class is used as a container of context for various read/write operations on other objects.
