Dear list,
I am having some trouble in using the beamer export.
First of all, I have problems in finding documentation on the exporter on-line. Is there an up-to-date manual of this exporter, and the list of options? By searching for a solution to my problem, I found many different notation around the web (the wiki, stackoverflow, etc.) but I could not find a solution to my very simple problem.
I have three images to show in my slide, one after the other (or one on top of the other).
In Latex beamer, I can write something like:
--------- begin-snippet-------------
\begin{figure}
\begin{center}
\includegraphics<1>[width=.7\textwidth]{figure1}
\includegraphics<2>[width=.7\textwidth]{figure2}
\includegraphics<3->[width=.7\textwidth]{figure3}
\end{center}
\end{figure}
--------- end-snippet-------------
and it works. How do I do the same in org-beamer?
I tried several options, for example this one:
--------- begin-snippet-------------
#+ATTR_BEAMER: :overlay <1>
[[ file:figure1 ]]
#+ATTR_BEAMER: :overlay <2>
[[ file:figure2 ]]
#+ATTR_BEAMER: :overlay <3>
[[ file:figure3 ]]
--------- end-snippet-------------
or
--------- begin-snippet-------------
*** :B_ignoreheading:
:PROPERTIES:
:BEAMER_env: ignoreheading
:BEAMER_act: <+>
:END:
[[file:figure1]]
[[file:figure2]]
[[file:figure3]]
--------- end-snippet-------------
and several other combinations of blocks, properties and attributes, but the generated latex output is always more or less the same:
--------- begin-snippet-------------
\includegraphics[width=.9\linewidth]{figure1}
\includegraphics[width=.9\linewidth]{figure2}
\includegraphics[width=.9\linewidth]{figure3}
--------- end-snippet-------------
Can someone help me to understand how to put overlays on figures?
I am using org-mode version 8.2.5h (pulled from the git repository about one month ago I guess) on Emacs 24.3.1
Thanks in advance,
Giuseppe Lipari
