Rescaling #+INCLUDES / Not centering #+INCLUDE?

Rescaling #+INCLUDES / Not centering #+INCLUDE?

Hi,

I have Emacs 26.3 + Org mode 9.4.6.

I tried to recompile an org-beamer file I created a few moths ago (see equivalent MCE attached), but it did not succeed.

The thing is I was #+INCLUDing a .dot file (also attached for completeness, but it could be any .dot file). I was putting the result inside a scalebox:

@@latex: \center \scalebox{.85}{@@
#+INCLUDE: test.dot src dot :file test.png
@@latex:}@@

I don't know how it was translated in previous versions of org-mode but it compiled perfectly.

Now I get error "! LaTeX Error: Something's wrong--perhaps a missing \item." during LaTeX compilation.

It seems the problem comes from the fact that the included file is automatically \begin{center}ed, which conflicts with my scalebox, as seen in output .tex file:

\begin{frame}[label={sec:org0a44c10}]{Test Slide}
 \center \scalebox{.85}{
\begin{center}
\includegraphics[width=.9\linewidth]{./images/DesignPatterns/23_DesignPatterns.png}
\end{center}

}
\end{frame}

When I remove the \begin/end{center}, the .tex file compiles fine.

I've tried to add ":center false" in the #+INCLUDE instruction and in a #+ATTR_LATEX preceding the #+INCLUDE. With no success.

I cannot find anything about centering (or not) a #+INCLUDE results in the docs nor in the mailing list.

Maybe there is a way to rescale the output without the \scalebox too, but I couldn't find how. Whatever I put in the #+ATTR_LATEX before the #+INCLUDE or in the #+INCLUDE (:cmdline -Gsize for dot) does not seem to be taken into account.

So any help would be appreciated.

BTW, thanks for the magnificent tools. I use them everyday and I love them!

Regards,

A data point: your example works just fine in org 9.5.

Arg... Yes sorry, I mixed up my MCE with my tests to get rid of the scalebox.

You'll find attached the actual non working .org file with the \scalebox that conflicts with the  \begin{center} that is automatically inserted by #+INCLUDE


My (unsuccessful) approaches so far to find a solution:
1. remove the automatic \begin{center} inserted by #+INCLUDE
   => using :center nil in #+INCLUDE or in additional #+ATTR_LATEX added above #+INCLUDE does not work
2. remove the use of \scalebox by using a more "org-mode"'s way of doing things
   => using :width in #+INCLUDE or in additional #+ATTR_LATEX or even passing options to dot have no effect (see previously attached file) 

Thanks for any help

PS: Sorry for my other mistake: I thought MELPA had latest org-mode, but I've now switched to actual lastest org-mode using git clone. Same problem occurs.

Confirmed: this version does not work for me either.

It is kind of late, but I think that the problem is not with Org. Rather
with LaTeX. Org uses \begin{center}..\end{center} around the image,
which cannot be used inside \scalebox. See

I have not tried to reproduce the issue, but provided latex snippet is 
quite strange. Accordingly to ORG-NEWS, \scalebox was added in 9.3 for 
tikz and pdf, while \includegraphics appeared in the example. In this 
case scale should be applied through \includegraphics option.

Anyway I expect \begin{center} around \scalebox, not inside it.

Finally it should be possible to pass :center nil through ob-dot to the 
generated image.
