Is there any way to know if annotation is manipulated using undo redo

Hi ,
We are trying to get to know whether annotations in viewer are added/modified/deleted by using AnnotationHistoryManager undo redo methods. Is it possible to know these type of events? if yes then how can we achieve this?

Thank you,
Vivek Sonawane


The annotationChanged event has a third parameter which is an object containing isUndoRedo
