Using the History Window

Every action performed on an image in the current session is added to the list in the History Window.


Closing or closing the image itself removes the entire editing history, clearing it entirely.  There is no way to recover an images' editing history once or the image is closed.

The history list can be used to step backward or forward through the changes made to the image.

To review the changes to the image, use Undo, Redo or click on an entry in the History Window.  The image will be rewound to the chosen point.


Toggle between one entry and the previous one by clicking repeatedly on the same entry in the History Window.  This is an easy way to review the changes that the target action made to the image

If an action has been undone, it appears in the list with a grey background. These actions may be redone by using Redo.


If a new action is performed while reviewing previous History actions, the new action will replace and erase all the remaining actions.  It is not possible to recover history items replaced in this way.
