Simplifies a linestring (sequence of points) using the standard Douglas-Peucker algorithm.
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.
nDistanceTolerance | the approximation tolerance to use |
void geos::simplify::DouglasPeuckerLineSimplifier::setPreserveClosedEndpoint | ( | bool | preserve | ) |
Sets whether the endpoint of a closed LineString should be preserved.
preserve | true if the endpoint should be preserved |
