Right. I haven't created code that performs intelligent RGB - CMYK
conversion; rather, I replace specific RGB values with
a PDFStream object, we can decode
the data string and do the replacement Ben suggested,
and then put it back to PDFStream.
I hope I don't miss any piece.

Folks,
If you haven't figured it out yet, let me inform you: FOP suffers from
large memory leaks. A memory leak in Java is nothing mysterious; it
occurs because a program never dereferences objects, which prevents the
Java garbage collector thread from reclaiming them. Thus, no matter how
and has a decent execution speed.
