You can always use the only environment. https://github.com/suvayu/.emacs.d/blob/master/org-mode-config.el#L215 That said, I think overlays with only is not as smooth as with simple overlay specifications to regular environments or macros like \includegraphics, \item, etc. As for an :overlay specification, I believe it is already supported but only for lists (ox-beamer.el:725). I would love to have that for images too! Cheers, -- Suvayu Open source is the future. It sets us free.
[O] Overlay in beamer?
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}
\includegraphics1[width=.7\textwidth]{figure1}
\includegraphics2[width=.7\textwidth]{figure2}
\includegraphics3-[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

The following works for me:

[[file:figure1.png]]
#+beamer: }\only2{
[[file:figure2.png]]
#+beamer: }\only3-{
[[file:figures3.png]]
#+beamer: }
Not pretty but...

Re: [O] Overlay in beamer?
Dear Eric,
thank you for your very fast answer!
I solved by using directly latex code, but I will also consider your
solution.
Since overlays are very much used in beamer, I was just wondering if it
would be easy (or even desirable) to add one more property to ATTR_LATEX
(or ATTR_BEAMER), so to specify overlays for figures ... something like
#+ATTR_BEAMER: :overlay 1-
(Was it available before? I just found this old thread:
http://stackoverflow.com/questions/6974560/how-do-i-use-overlay-specifications-for-lists-in-org-modes-beamer-export-featur
)
Thanks again,
Giuseppe Lipari

Of course, you could put each figure in a separate block. The following/attached will match what you had originally. #+options: H:1 * The slide ** figure 1 :PROPERTIES: :beamer_act: 1 :END: [[file:chromosome.png]] ** figure 2 :PROPERTIES: :beamer_act: 2 :END: [[file:diagram.png]] ** figure 3 :PROPERTIES: :beamer_act: 3- :END: [[file:equation1.png]] What may not be easy or possible is to use the \only directive, which is what I used in my previous response to you. -- : Eric S Fraga (0xFFFCF67D), Emacs 24.4.50.2, Org release_8.2.6-923-g233c11
