org-latex-image-default-width ignored

[Julien Cubizolles]

I'd like all inline images resized during beamer and latex export. I
tried setting org-latex-image-default-width to ".3\\linewidth" but after
export the latex file still uses the default .9\linewidth default. See
the following examples.

Julien.

orgmode file:
--8<---------------cut here---------------start------------->8---
#+begin_src emacs-lisp :exports none
  (setq org-latex-image-default-width ".3\\linewidth")
#+end_src

#+RESULTS:
: .3\linewidth

* hello
[[file:file:/home/wilk/enseignement/schemas/plickers/mvmt-circ-F-faux.png]]
--8<---------------cut here---------------end--------------->8---

gets exported to:
--8<---------------cut here---------------start------------->8---

Your example works for me with up to date org from git.  What version
are you using?

Found the cause of the problem, my default configuration exports in
async mode, so this variable should be set in
org-export-async-init.el.

Is there a way to have a variable set during export to avoid setting it
for all exports?

I've never used the async export so I am not sure but maybe check out
the #+bind: directive?

I tried

--8<---------------cut here---------------start------------->8---
#+BIND: org-latex-image-default-width ".3\\linewidth"
--8<---------------cut here---------------end--------------->8---

with no success in async mode, but it works in synchronous mode. I guess
I'll avoid async mode for now on, or use a set of different
org-export-async-init.el files for different files.

Nevertheless I think it would make sense to have a way to set some
variables during async export. According to the Org Manual:

--8<---------------cut here---------------start------------->8---
Emacs variables can become buffer-local during export by using the BIND
keyword.  Its syntax is ‘#+BIND: variable value’.  This is particularly
useful for in-buffer settings that cannot be changed using keywords.
--8<---------------cut here---------------end--------------->8---

But the options set using #+ keywords are used during async export while
those set using #+BIND are ignored. A "+BIND-ASYNC would come in handy.
