Class View

java.lang.Object
  com.tensegrity.graphics.View

All Implemented Interfaces:

java.io.Serializable

public class View

extends java.lang.Object

implements java.io.Serializable

This class defines a view on a given child component.

A View consists of the following attributes:

• tx - translation in x direction
• ty - translation in y direction
• sx - scaling in x direction defaults to 1.0
• sy - scaling in y direction defaults to 1.0
• angle - rotation defaults to 0.0
• rot_tx - the rotation pivot point's x coordinate, defaults to 0.0
• rot_ty - the rotation pivot point's y coordinate, defaults to 0.0
