I tried that, but still got the error about \beamer being undefined.
However, my understanding is that, if I am exporting to LaTeX, then
BEGIN_SRC latex
and
BEGIN_EXPORT latex
do the same thing. So if I have the following in my org file:
#+BEGIN_EXPORT latex
\newlength\mytextheight\makeatletter\setlength\mytextheight{\beamer@frametextheight}\makeatother
#+END_EXPORT
#+BEGIN_SRC latex
\newlength\mytextheight\makeatletter\setlength\mytextheight{\beamer@frametextheight}\makeatother
#+END_SRC
I get
\newlength\mytextheight\makeatletter\setlength\mytextheight{\beamer@frametextheight}\makeatother
\newlength\mytextheight\makeatletter\setlength\mytextheight{\beamer@frametextheight}\makeatother
in my tex file.

Using
#+LATEX_HEADER:
\newlength\mytextheight\AtBeginDocument{\makeatletter\setlength\mytextheight{\beamer@frametextheight}\makeatother}
also leads to the error
! Undefined control sequence.
\beamer
So I went with \paperheight instead, which works fine.

That's what I suspected. You could try to wrap this line in an
#+begin_export latex block (as I suggested), then it will be within the
document instead of in the preamble.
I usually refrain from using AtBeginDocument hooks (Gustavo Barros'
suggestion) because I do not know enough about them, so I rather add the
commands to a place I can see ;-)

Hm, src-block? I would have thought you should wrap that in an
export-block, so those commands get added to the exported document, not
quoted within as a source code. That would mean
#+begin_export latex
\newlength\mytextheight\makeatletter\setlength\mytextheight{\beamer@frametextheight}\makeatother
#+end_export

It seems that, if you try to set the length in your preamble,
`\beamer@frametextheight` is not yet defined.
So, you might try the hook `\AtBeginDocument` to see if the
definition comes at
a better timing.
#+LATEX_HEADER:
\newlength\mytextheight\AtBeginDocument{\makeatletter\setlength\mytextheight{\beamer@frametextheight}\makeatother}
As I said, it's a hunch, for I haven't tested. But I think it
may be it.
Why not put the entire thing inside \AtBeginDocument?
To the OP: \paperheight does seem to be available in Beamer.
Couldn't you use that?

Louis,
a hunch, which might work.
It seems that, if you try to set the length in your preamble,
`\beamer@frametextheight` is not yet defined.
So, you might try the hook `\AtBeginDocument` to see if the definition
comes at a better timing.
#+LATEX_HEADER:
\newlength\mytextheight\AtBeginDocument{\makeatletter\setlength\mytextheight{\beamer@frametextheight}\makeatother}
As I said, it's a hunch, for I haven't tested. But I think it may be it.
Best,
Gustavo.

Oh, or perhaps just a typo is involved: is it really

Also, you may need to define your mytextheight as a length and then use
\setlength instead of \let.

Re: [O] Placement of \makeatletter with \beamer@frametextheight
Hi Loris,
I don't know beamer enough to propose an elegant solution. Nonetheless I
have ideas what might go wrong here.
Am 29.11.18 um 08:17 schrieb Loris Bennett:
>> #+latex_header:

First, \let copies the at-the-moment-of-definition version of
\beamer@frametexheight to \mytextheight. This happens in the preamble.
I expect beamer to set up things like frame height at the begin of the
document (exactly the \begin{document} line), not earlier. Thus at the
point of that \let, that length isn't what you want yet.
Solution to this:
#+begin_export latex
\makeatletter...
#+end_export
Second, \let creates a macro whereas it then is used as a length for the
figure. I doubt that is possible.
If that's the reason, you might try
#+begin_export latex
\newlength\mytextheight
\makeatletter
\setlength\mytextheight{\beamer@frametexheight}
\makeatother
#+end_export
Perhaps this gives you a starting point to further play with it.
HTH,
Julius

Thanks, but with that I get
! Undefined control sequence.
\Gin@@eheight ->0.75\mytextheight
However, the tex file looks OK:
...
\usepackage[sfdefault]{Fira Sans}
\makeatletter\let\mytextheight\beamer@frametexheight\makeatother
\definecolor{mFubMainGreen}{HTML}{99CC00}
...
\begin{center}
\includegraphics[height=0.75\mytextheight]{../../common/resources.png}
\end{center}
...
Any ideas what might still be going wrong?

[O] Placement of \makeatletter with \beamer@frametextheight
Hi, I want to specify the size of a graphic in an Beamer presentation generated from my org file. The following #+ATTR_LATEX: :height 0.75\textheight works, but #+ATTR_LATEX: :height 0.75\beamer@frametextheight I get the error ! Undefined control sequence. \Gin@@eheight ->0.5\beamer @frametextheight I assume I need to insert a \makeatletter at the appropriate point. Where would that be?
