Class: QgsAbstractGeometrySimplifier

class qgis.core.QgsAbstractGeometrySimplifier

Bases: sip.wrapper

Abstract base class for simplify geometries using a specific algorithm

Methods

isGeneralizableByDeviceBoundingBox

Returns whether the device-envelope can be replaced by its BBOX when is applied the specified tolerance

simplify

Returns a simplified version the specified geometry

isGeneralizableByDeviceBoundingBox(envelope: QgsRectangle, mapToPixelTol: float = 1) → bool

Returns whether the device-envelope can be replaced by its BBOX when is applied the specified tolerance

isGeneralizableByDeviceBoundingBox(points: Iterable[Union[QPointF, QPoint]], mapToPixelTol: float = 1) -> bool Returns whether the device-geometry can be replaced by its BBOX when is applied the specified tolerance

Parameters
Return type

bool

simplify(self, geometry: QgsGeometry)QgsGeometry

Returns a simplified version the specified geometry

simplify(self, geometry: QgsAbstractGeometry) -> QgsAbstractGeometry Returns a simplified version the specified geometry.

Will return None if no simplification is to be performed to the geometry.

Caller takes ownership of the returned geometry.

New in version 3.18.

Parameters

geometry (QgsGeometry) –

Return type

QgsGeometry
