QgsVectorSimplifyMethod () | |
construct a default object | |
bool | forceLocalOptimization () const |
Gets where the simplification executes, after fetch the geometries from provider, or when supported, in provider before fetch the geometries. | |
float | maximumScale () const |
Gets the maximum scale at which the layer should be simplified. | |
void | setForceLocalOptimization (bool localOptimization) |
Sets where the simplification executes, after fetch the geometries from provider, or when supported, in provider before fetch the geometries. | |
void | setMaximumScale (float maximumScale) |
Sets the maximum scale at which the layer should be simplified. | |
void | setSimplifyAlgorithm (Qgis::VectorSimplificationAlgorithm simplifyAlgorithm) |
Sets the local simplification algorithm of the vector layer managed. | |
void | setSimplifyHints (Qgis::VectorRenderingSimplificationFlags simplifyHints) |
Sets the simplification hints of the vector layer managed. | |
void | setThreshold (float threshold) |
Sets the simplification threshold of the vector layer managed. | |
