Replaces the current image with the one at Position in the Undo stack.
Parameter
Description
Position
Undo index to restore: 0 = last saved undo, 1 = second to last saved undo, 2... up to UndoCount - 1
AutoUndoRedo
Set to true for automatic redo support. Saves the current state (before undo) to the redo stack (i.e. calls SaveRedo) and removes this and prior entries from the Undo stack
Note: AutoUndoRedo should always be set to true if you support multiple undo (i.e. UndoLimit > 1 )
// Undo the last item (same as calling ImageEnView1.Proc.Undo) ImageEnView1.Proc.UndoAt( 0, True );
// Undo All ImageEnView1.Proc.UndoAt( ImageEnView1.Proc.UndoCount, True );
Compatibility Information
In v6.2.1 and older versions, AutoUndoRedo would only assign the current state to the Redo List, and the undone item is not cleared. From v6.3.0, AutoUndoRedo clears all undone entries and assigns them to the redo list.
