Any thoughts? > > --Steve Hi Steve, the examples are indeed out-dated. 1) 'backend is now 'org-export-current-backend (though I am not sure, I think there was also 'latexp at some time). 2) If the latex block is evaluated at all and a file argument is present, this will be used. So the block meant to go the latex->PDF route should not contain the :file argument. 3) Even if ":results graphics" or ":results file" is specified, the results of a latex block seem to be wrapped in #+begin_latex...#+end_latex. So for the block meant to go to the html, one way is to specify ":results org". But here I get a spurious ORG-ORG-START ... Anyway, besides that ORG-ORG-START thing, this seems to work on my side: ,---- | * Tikz test | #+name: contents | #+begin_src latex :exports (if (and (boundp 'org-export-current-backend) (eq org-export-current-backend 'latex)) "results" "none") :results latex | \begin{tikzpicture} | \node[red!50!black] (a) {A}; | \node (b) [right of=a] {B}; | \draw[->] (a) -- (b); | \end{tikzpicture} | #+end_src | | #+begin_src latex :exports (if (and (boundp 'org-export-current-backend) (eq org-export-current-backend 'latex)) "none" "results") :results file :file test.png :imagemagick yes :iminoptions -density 600 :imoutoptions -geometry 400 :fit yes :noweb yes :headers '("\\usepackage{tikz}") | <> | #+end_src `---- Regards, Andreas
