[org-e-beamer-export-to-latex] howto put intra-frame latex?

[Myles English]

Hello again,

Does anyone have a solution to this?  I am attempting to give one slide
only a background image.

I can set the background image but can't unset it because the latex
directive needs to come after the \end{frame} of the slide with the
background and before the \begin{frame} of the slide without the
background.  Like so (this works):

#+begin_latex
\section{Start the slides}
\label{sec-1}
\setbeamertemplate{background canvas}%
                  {\ThisULCornerWallPaper{1}%
                    {/home/myles/me_on_a_horse.jpg}}


\begin{frame}[label=sec-1-1]{A slide}
first slide content
\end{frame}

\setbeamertemplate{background canvas}{\ClearWallPaper}

\begin{frame}[label=sec-1-2]{Another slide}
more content here

\end{frame}
#+end_latex


However when the org example at the end of this mail is exported, I get
this (i.e. the \ClearWallPaper is before the \end{frame}, and it needs
to be after):


#+begin_latex
%[snip]
\begin{frame}[label=sec-1-2]{Another slide}
more content here

\setbeamertemplate{background canvas}{\ClearWallPaper}
\end{frame}
%[snip]
#+end_latex


And finally, the example:

--------------------------------// BEGIN tests.org //--------

#+STARTUP: indent

                      {/home/myles/me_on_a_horse.jpg}}
#+end_latex


** A slide

first slide content


** Another slide

more content here

#+begin_latex
\setbeamertemplate{background canvas}{\ClearWallPaper}
#+end_latex

** Last slide

Content on the last slide


--------------------------------// END tests.org //--------


Freestyling a bit: I am wondering if the use case is a bit like that for
inline tasks; for something that doesn't fully belong in the tree structure,
that is more file-local in scope, but still needs to know it's position in the
file.

Thanks,

Myles

Doesn't ignoreheading work?

** dummy frame                     :B_ignoreheading:
   :PROPERTIES:
   :BEAMER_env: ignoreheading
   :END:

\LaTeX command outside frame

Ah yes it does that is much tidier than my answer.

Thanks,

Well reading the manual/src helped, of course, and I have altered the
example below if any one else is wondering.

Because I have H:2 in the #+OPTIONS line, a level 1 heading does not
make a frame and can be used sneak in some latex.
