Point geometry type, with support for z-dimension and m-values.
The QgsQuickMapSettings class encapsulates QgsMapSettings class to offer settings of configuration of...
void extentChanged()
Geographical coordinates of the rectangle that should be rendered.
void outputSizeChanged()
The size of the resulting map image.
double mapUnitsPerPoint
Returns the distance in geographical coordinates that equals to one point unit in the map.
void rotationChanged()
The rotation of the resulting map image, in degrees clockwise.
Q_INVOKABLE QPointF coordinateToScreen(const QgsPoint &point) const
Convert a map coordinate to screen pixel coordinates.
void mapPointChanged()
Point in map coordinates.
QPointF screenPoint
Point in screen coordinates (read-only)
QgsQuickMapSettings * mapSettings
Map settings used to define the map canvas CRS and detect any extent change.
void mapDistanceChanged()
