timerEvent(self, QTimerEvent)

toCanvasCoordinates(self, point: QgsPointXY) → QPoint

Transforms a point from map coordinates to screen coordinates.

toLayerCoordinates(self, layer: QgsMapLayer, point: QPoint) → QgsPointXY

Transforms a point from screen coordinates to layer coordinates.

toLayerCoordinates(self, layer: QgsMapLayer, point: QgsPointXY) -> QgsPointXY Transforms a point from map coordinates to layer coordinates.
