Class: QgsGeometrySnapper¶

class qgis.analysis.QgsGeometrySnapper¶

Bases: PyQt5.QtCore.QObject

QgsGeometrySnapper allows a geometry to be snapped to the geometries within a different reference layer. Vertices in the geometries will be modified to match the reference layer features within a specified snap tolerance.

snapFeatures(self, features: object, snapTolerance: float, mode: QgsGeometrySnapper.SnapMode = QgsGeometrySnapper.PreferNodes) → object¶: Snaps a set of features to the reference layer and returns the result. This operation is multithreaded for performance. The featureSnapped() signal will be emitted each time a feature is processed. The snap tolerance is specified in the layer units for the reference layer.

snapGeometry(self, geometry: QgsGeometry, snapTolerance: float, mode: QgsGeometrySnapper.SnapMode = QgsGeometrySnapper.PreferNodes) → QgsGeometry¶

Snaps a geometry to the reference layer and returns the result. The geometry must be in the same CRS as the reference layer, and must have the same type as the reference layer geometry. The snap tolerance is specified in the layer units for the reference layer.

snapGeometry(geometry: QgsGeometry, snapTolerance: float, referenceGeometries: object, mode: QgsGeometrySnapper.SnapMode = QgsGeometrySnapper.PreferNodes) -> QgsGeometry Snaps a single geometry against a list of reference geometries.
