TImageEnProc.RedoAt

Declaration

procedure RedoAt(Position: Integer; AutoUndoRedo: Boolean = False);

Description

Replaces the current image with the image at Position in the redo stack.

Parameter	Description
Position	Redo index to restore: 0 = last saved redo, 1 = second to last saved redo, 2... up to RedoCount - 1
AutoUndoRedo	Set to true for automatic undo support. Saves the current state (before redo) to the undo stack (i.e. SaveUndo is called) and removes this and prior entries from the Redo stack

Note: AutoUndoRedo should always be set to true if you support multiple undo (i.e. UndoLimit > 1 )
