Undo and Redo
Undo and Redo provide a simple way of reverting changes to the image as long as they have not yet been saved.
The Undo toolbar button
reverts the
image to the state it had before the previously performed action. The
Image Editor supports unlimited Undo back to the point when the image was
opened or last saved.
The Redo toolbar button
will cancel
the previous Undo, and re-perform the action which has been undone.
If multiple actions have been undone, multiple clicks on the Redo toolbar
button will redo each of the undone actions.
