Hi John,

I use blocks like the following to create standalone pdfs.

#+begin_src latex :file stuff/epr-logo.pdf :border 1.75em :packages '(("" "tikz")) :exports none
  \usetikzlibrary{shapes,arrows,shadows,decorations,decorations.text}
  \tikzstyle{line} = [draw, ultra thick, -latex']
  {\huge
    \begin{tikzpicture}[scale=0.5]
      \path
      [decorate,
      decoration={text along path,
        text={main(int argc, char *argv[]) int a; int b; if(a!=b) a++1;}}]
        (0,2) cos (3,0.5);
        \path
        [decorate,
        decoration={text along path,
          text={argc, char *argv[]) int a; int b; if(a!=b) a++1;}}]
        (4.5,-0.5) sin (8,-2) cos (12,0) sin (16,2) cos (19,0.5);
      \path
      [decorate,
      decoration={text along path,
        text={main(int argc, char *argv[]) int a; int b; if(a!=b) a++1;}}]
        (0,-2) cos (4,0) sin (8,2) cos (11,0.5);
      \path
      [decorate,
      decoration={text along path,
        text={[]) int a; int b; if(a!=b) a++1;}}]
      (12.5,-0.5) sin (16,-2) cos (20,0) sin (24,2);
      \path
      [decorate,
      decoration={text along path,
        text={if(a!=b) a++1;}}]
      (20.5,-0.5) sin (24,-2);
  \end{tikzpicture}
  }
#+end_src

I then normally use the convert command if I want to change the
resulting pdf into a png or other image type more suitable for web
publishing.

Best -- Eric
