Package org.locationtech.jtslab.clip

Class RectangleClipPolygon

java.lang.Object

org.locationtech.jtslab.clip.RectangleClipPolygon

public class RectangleClipPolygon
extends Object

Clips polygonal geometry to a rectangle. This implementation is faster, more robust, and less sensitive to invalid input than Geometry.intersection(Geometry). It can also enforce a supplied precision model on the computed result. The inputs do not have to meet the precision model. This allows clipping using integer coordinates in the output, for example.
