Not quite. PDF is based on postscript (version 3). While it doesn't
have to be compressed, it can be (flate or zip encoding).
Additionally, PDFs may be "encrypted". This means that it's not as
simple to create PDFs as straight postscript, but it isn't too
difficult (I wrote a simple Java library that creates line art PDFs
without too much trouble).
