Best,
Andreas
PS: BTW, it requires tons of header arguments. These can be split over
several lines:
,----
| * Tikz test
| #+name: contents
| #+header: :exports (if (and (boundp 'org-export-current-backend) (eq org-export-current-backend 'latex)) "results" "none")
| #+header: :results latex
| #+begin_src latex
| \begin{tikzpicture}
| \node[red!50!black] (a) {A};
| \node (b) [right of=a] {B};
| \draw[->] (a) -- (b);
| \end{tikzpicture}
| #+end_src
|
| #+header: :exports (if (and (boundp 'org-export-current-backend) (eq org-export-current-backend 'latex)) "none" "results")
| #+header: :results org :file test.png
| #+header: :imagemagick yes :iminoptions -density 600 :imoutoptions -geometry 400
| #+header: :fit yes :noweb yes :headers '("\\usepackage{tikz}")
| #+begin_src latex
| <<contents>>
| #+end_src
