OOF2: The Manual
OOF.Image.Undo — Undo an Image modification.
Image in a
Microstructure has associated with it a stack of
modified versions of the
Image. When the
Image is modified, the new
version is pushed onto the stack. The Undo
command pops the topmost version off the stack, thereby reverting
to the next older version. The popped version is not destroyed,
however. It can be recovered with OOF.Image.Redo.
