Class: QgsVectorSimplifyMethod¶

Contains settings for simplifying geometries fetched from a vector layer.

class qgis.core.QgsVectorSimplifyMethod[source]¶

Bases: object

forceLocalOptimization(self) → bool[source]¶

Gets where the simplification executes, after fetch the geometries from provider, or when supported, in provider before fetch the geometries

maximumScale(self) → float[source]¶

Gets the maximum scale at which the layer should be simplified

setForceLocalOptimization(self, localOptimization: bool)[source]¶

Sets where the simplification executes, after fetch the geometries from provider, or when supported, in provider before fetch the geometries

setMaximumScale(self, maximumScale: float)[source]¶

Sets the maximum scale at which the layer should be simplified

setSimplifyAlgorithm(self, simplifyAlgorithm: Qgis.VectorSimplificationAlgorithm)[source]¶

Sets the local simplification algorithm of the vector layer managed

Sets the simplification hints of the vector layer managed

Parameters:: simplifyHints (Union[Qgis.VectorRenderingSimplificationFlags, Qgis.VectorRenderingSimplificationFlag])

setThreshold(self, threshold: float)[source]¶

Sets the simplification threshold of the vector layer managed

setTolerance(self, tolerance: float)[source]¶

Sets the tolerance of simplification in map units. Represents the maximum distance in map units between two coordinates which can be considered equal

Gets the local simplification algorithm of the vector layer managed

Gets the simplification hints of the vector layer managed

threshold(self) → float[source]¶

Gets the simplification threshold of the vector layer managed

tolerance(self) → float[source]¶

Gets the tolerance of simplification in map units. Represents the maximum distance in map units between two coordinates which can be considered equal
