Depends on what you mean by "transparent". 
Obviously, you will have some objects (texts or something) which are the
"transparent" color (black), and due to the fact that they are
transparent, you see what is behind them.
Now, the question is what exactly you would expect to see behind them.
If you want to see the things that are below the *PDF*, then it's not
possible. 
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
text, or something), then it's possible, by tweaking lib/devices/swf.c a
bit (look for gfxcolor_t objects, and rewrite the .a member if
r/g/b are e.g. black).
