Class Transformation

  • public class Transformation
extends java.lang.Object
    Transformation between device-independent coordinates and standard Java coordinates. The aspect-ratio will be the same. The position in the canvas is determined by a Rectangle defining a (virtual) paper which is placed in the canvas according to an anchor point. Depending on the aspect ratio of the canvas the paper width or height occupies the canvas width or height.
