All Implemented Interfaces:

PathConstructor

Direct Known Subclasses:

PolylinePathConstructor

public abstract class CubicToLinePathConstructor

extends QuadToCubicPathConstructor

Implements cubics by approximating them using a polyline. Useful class for output formats that do NOT implement bezier curves at all, or if you need only straight lines.
