Yes I found this nice piece of code=20=20

It switches to svg if backend is html and to raw latex if backend is
latex. You only have to tweak it your needs.

#+header: :file (by-backend (html "tree.svg") (t 'nil))
#+header: :imagemagick
#+header: :results (by-backend (pdf "latex") (t "raw"))
#+begin_src latex
  \usetikzlibrary{trees}
  \begin{tikzpicture}
    \node [circle, draw, fill=3Dred!20] at (0,0) {1}
    child { node [circle, draw, fill=3Dblue!30] {2}
      child { node [circle, draw, fill=3Dgreen!30] {3} }
      child { node [circle, draw, fill=3Dyellow!30] {4} }};
  \end{tikzpicture}
#+end_src

* COMMENT setup
#+begin_src emacs-lisp :results silent
  (setq org-babel-latex-htlatex "htlatex")
  (defmacro by-backend (&rest body)
    `(case (if (boundp 'backend) (org-export-backend-name backend) nil) ,@b=
ody))
#+end_src
