D View, Save and Restore View Methods

2D views now have 4 view stores that allow storage and retrieval of the current view state. They can be accessed by the saveview() and restoreview() methods:

!myview.SaveView( !storeNumber )

!myview.RestoreView( !storeNumber )

where !StoreNumber must be in the range 1 to 4.

If the view’s picture is deleted or changed then the view-stores are all cleared. The stored view settings should survive saving and restoring to a binary-save file.
