Class RContour

java.lang.Object

geomerative.RGeomElem

geomerative.RContour

public class RContour
extends RGeomElem

RContour is a reduced interface for creating, holding and drawing contours. Contours are ordered lists of points (RPoint) which define the outlines of polygons. Contours can be self-intersecting.
