Using different image format given the export backend

Using different image format given the export backend

[Garrido Xavier]

Dear Orgers,

As explain is this forum thread 
http://stackoverflow.com/questions/13611837/how-can-i-use-different-image-formats-for-different-exports-in-org-mode, 
I'd also like to use different image format given the export backend. I 
have used the answer provided in the forum to have something like that

#+CAPTION: Toto figure
#+NAME: fig::toto
#+ATTR_LATEX: :width 0.38\textwidth
#+BEGIN_SRC emacs-lisp :exports results :results value raw
   (case (and (boundp 'backend) backend)
     (nil "")
     (latex "[[file:./toto.pdf]]"
     (html  "[[file:./toto.png]]"))
#+END_SRC

While the export is fine with html, when I export to latex->pdf, it 
gives me :

\includegraphics[width=.9\linewidth]{./toto.pdf}

not respecting the latex width attribute nor caption. I am using the new 
exporter and I wonder if I can get something working in the same way.

Thanks a lot for your help,
Xavier

I do it like this:

(defun vb-massage-includegraphics (str backend opts)
  (replace-regexp-in-string ".png}" ".pdf}" str))
(add-hook 'org-export-filter-final-output-functions
          'vb-massage-includegraphics)

And then, simply refer to the png file in the .org file. Then nothing
happens for the html output, but on latex export, the regexp matches the
'}' and includes the .pdf file instead.

That is extremely ugly, and makes plenty of assumptions, most of all
that the .pdf file exists. And it should probably test for the value of
'backend'. But for personal use, it is convenient ...

           /v

Hi Vincent,

Thanks for the trick. Until I found something else I will try it ;)
