Class BoxToBound  

java.lang.Object
  com.port80.graph.dot.impl.BoxToBound

---

public class BoxToBound

extends java.lang.Object

Construct bounding polygon from path boxes. . Since the code make assumption on the constant values, the constants and routine are packed into this class to decouple them from others.
