Class BezierNode

java.lang.Object
org.jhotdraw8.geom.shape.BezierNode
public class BezierNode extends Object
Represents a node of a bezier path. A node has up to three control points:
  • px,py: POINT is the point through which the curve passes.
  • ix,iy: IN controls the tangent of the curve going towards C0.
  • ox,oy: OUT controls the tangent of the curve going away from C0.
A bit mask specifies which control points are in use.
