Depends on what you mean by "transparent". 
Obviously, you will have some objects (texts or something) which are the

transparent, you see what is behind them.
Now, the question is what exactly you would expect to see behind them.

If you just want to see the things in the PDF itself that are below the
objects in question (like, the background gradient behind the black
