Class RotatablePaperTransform

java.lang.Object

org.jplot2d.transform.PaperTransform

org.jplot2d.transform.RotatablePaperTransform

All Implemented Interfaces:

java.lang.Cloneable

public class RotatablePaperTransform
extends PaperTransform

Defines the conversion between paper units and device units. Every component has its own paper coordinate system, and maintains a PaperTransform object.

The transform is defined by 4 parameters. The xoff is the paper distance between component left bound to device left bound. The yoff is the paper distance between component bottom bound to device top bound. The scale is the factor of device to paper. The theta is the conter-clockwise rotation angle in radians.
