Member Enumeration Documentation

enum QgsVectorSimplifyMethod::SimplifyHint

Simplification flags for fast rendering of features.

Enumerator:

NoSimplification	No simplification can be applied.
GeometrySimplification	The geometries can be simplified using the current map2pixel context state.
AntialiasingSimplification	The geometries can be rendered with 'AntiAliasing' disabled because of it is '1-pixel size'.
FullSimplification	All simplification hints can be applied ( Geometry + AA-disabling )
