org.jhotdraw.draw.event.TransformRestoreEdit

All Implemented Interfaces:

public class TransformRestoreEdit
extends javax.swing.undo.AbstractUndoableEdit

An UndoableEdit event which can undo a lossy transform of a single Figure by restoring the figure using its transform restore data.

This object is useful for undoing lossy transformations, such as the rotation, scaling or shearing of a figure.

The transform restore data may consume a lot of memory. Undos of lossless transforms, such as translations of a figure, should use TransformEdit.
