Thanks for the compliments.

That's why I named it "covering unwanted sections", see. 

I know very well the difference between "covering" and "removing".
And I know to say "remove" when I mean "remove".

Use-cases may be quite simple: 

 * printing only relevant parts of pages (leaving out ads from
   scanned magazine articles, or parts of articles continued from
   previous pages). Do you get that use case?

 * showing only relevant parts on pages of a PDF presentation.
   (Get it.)

Your surmising guesswork does not help anyone.

But you hopefully can see now that you jumped to your own conclusion
without understanding what was expressed.

No, it's not. And if it is, may I send you a few example files and
ask you to do that trivial job for me? Can you also teach me to do
such trivials thing for myself? - Of course, I'll pay you for your 
effort, according to the time required  (but it indeed needs to be 
a trivial thing to do).
