Thanks for the tip. I am already doing that but for me remembering the changes even after the file is saved and closed is a big challenge.
Anyways I am trying to make a way of this problem.
One last thing I am not able to get what adjustment user has made in effect dialog. I am using this code to bring up Effect Dialog: ImageEnView1.Proc.DoPreviews(ppeEffects)
Any ideas as to how we can extract all the effects that the user has applied and the order in which these effects have been applied?
