Member Function Documentation

◆ setDistanceTolerance()

void geos::simplify::DouglasPeuckerLineSimplifier::setDistanceTolerance ( double  nDistanceTolerance)

Sets the distance tolerance for the simplification.

All vertices in the simplified linestring will be within this distance of the original linestring.

Parameters
nDistanceTolerancethe approximation tolerance to use

◆ setPreserveClosedEndpoint()

void geos::simplify::DouglasPeuckerLineSimplifier::setPreserveClosedEndpoint ( bool  preserve)

Sets whether the endpoint of a closed LineString should be preserved.

Parameters
preservetrue if the endpoint should be preserved
