Interface SmootherControl

public interface SmootherControl

Defines methods to control the smoothing process. LineSmoother has a default implementation that specifies a constant number of vertices in smoothed segments and no lower bound on the distance between input vertices for smoothing.

To customize smoothing, pass your own implementation to AbstractSmoother.setControl(org.jaitools.jts.SmootherControl)

Method Summary

Modifier and Type	Method and Description
double	getMinLength() Gets the minimum distance between input vertices for the segment to be smoothed.
int	getNumVertices(double length) Given an input segment length, returns the number of vertices to use for the smoothed segment.

Method Detail

getMinLength

double getMinLength()

Gets the minimum distance between input vertices for the segment to be smoothed. Segments smaller than this will be copied to the output unchanged.

Returns:

minimum segment length for smoothing

getNumVertices

int getNumVertices(double length)

Given an input segment length, returns the number of vertices to use for the smoothed segment. This number includes the segment end-points.

Parameters:

length - input segment length

Returns:

number of vertices in the smoothed segment including the end-points
