I want to create a desktop application, whose functioning is as follows :
1. user opens a pdf file in the form
2. then, it gets opened up on the UI. After that, user performs certain editing using mouse
like drawing a rectangle, crossing a certain region (similar to paint)
3. Then, after doing all the editing, he saves that file into another pdf (edited one)
I am doing it in c#. Can you suggest, how to do it ?
