Class: QgsTopologyPreservingSimplifier¶
Implementation of GeometrySimplifier using the Douglas-Peucker algorithm.
Simplifies a geometry, ensuring that the result is a valid geometry having the same dimension and number of components as the input. The simplification uses a maximum distance difference algorithm similar to the one used in the Douglas-Peucker algorithm.
