I now use TikZ to do that. I have the impression it is easier. Though, I have the real impression of writing LaTeX inside an Org buffer... which I dislike. I'd like to write text as text, and still get the ability to convert that to HTML, for review, even if the layout wouldn't be (at all) the same. > I would like something like this in the beamer export: > > \begin{textblock}{10}(3,3) \visible <2-> { > \includegraphics[width=.9\linewidth]{scatterplot2.png} > } \end{textblock} > > I have defined the following beamer environment. > > (add-to-list 'org-beamer-environments-extra > '("textpos1" "w" "\\begin{textblock}{%h}(3,3) \\visible %a {" "} \\end{textblock}")) You normally could use such a block (the old "org-special-blocks", now integrated in Org 8 -- thanks Nicolas): --8<---------------cut here---------------start------------->8--- #+begin_textblock Contents #+end_textblock --8<---------------cut here---------------end--------------->8--- > The problem is (3,3) is fixed in the above specification.

Though, the problem stays the same with what I think is the right way to do it... See how Org gets converted to LaTeX: --8<---------------cut here---------------start------------->8--- #+begin_myenvironment \begin{myenvironment} Test of a new Test of a new environment. environment. #+end_myenvironment \end{myenvironment} --8<---------------cut here---------------end--------------->8--- That's OK. But the environment had no parameters. --8<---------------cut here---------------start------------->8--- #+begin_myenvironment{3} \#+begin\_myenvironment\{3\} Test of a new Test of a new environment. environment. #+end_myenvironment \#+end\_myenvironment --8<---------------cut here---------------end--------------->8--- That's completely invalid LaTeX. --8<---------------cut here---------------start------------->8--- #+begin_myenvironment {3} \begin{myenvironment} Test of a new Test of a new environment. environment. #+end_myenvironment \end{myenvironment} --8<---------------cut here---------------end--------------->8--- That's valid LaTeX, but the arguments of the environment have been ignored! IIRC, that's how we did before, with the original `org-special-blocks' file. > How does one use the escape %o?
