Detailed Description

Simplifies a linestring (sequence of points) using the standard Douglas-Peucker algorithm.

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

nDistanceTolerance

the approximation tolerance to use

setPreserveClosedEndpoint()

void geos::simplify::DouglasPeuckerLineSimplifier::setPreserveClosedEndpoint

(

bool

preserve

)

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

Parameters

preserve

true if the endpoint should be preserved
