Class View2D

java.lang.Object

ur_rna.StructureEditor.services.drawing.View2D

public class View2D
extends java.lang.Object

Encapsulates the AffineTransform that converts from model coordinates to screen coordinates along with its inverse transform and allows conversion of points between the two. Also contains the bounds of the screen in both coordinate systems.
