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?
Cheers,
Loris

Nonetheless I have ideas what might go wrong here.

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.

After correcting the typo I followed Eric's and Julius's suggestions and I tried adding #+LATEX_HEADER: \newlength\mytextheight\makeatletter\setlength\mytextheight{\beamer@frametextheight}\makeatother to the beginning of the Org file, but in this case \the\mytextheight is 0.0pt.

Using #+LATEX_HEADER: \newlength\mytextheight\AtBeginDocument{\makeatletter\setlength\mytextheight{\beamer@frametextheight}\makeatother} also leads to the error ! Undefined control sequence. <argument> \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 ;-) > After that I tried adding the definition on the slide itself > > #+BEGIN_SRC latex > \newlength\mytextheight\makeatletter\setlength\mytextheight{\beamer@frametextheight}\makeatother > #+END_SRC 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 HTH, Julius ^ permalink raw reply [flat|nested] 13+ messages in thread

However, my understanding is that, if I am exporting to LaTeX, then BEGIN_SRC latex and BEGIN_EXPORT latex do the same thing.
