WebbA geometry is the spatial representation of a feature. QgsGeometry acts as a generic container for geometry objects. QgsGeometry objects are implicitly shared, so making … WebbThe Simplification Tolerance parameter value determines the degree of simplification. The larger the tolerance, the more coarse the resulting geometry. Smaller tolerances generate geometry that more accurately represents the input. The MinSimpTol and MaxSimpTol fields will be added to the output to store the tolerance that was used.
