graphics for html and latex / pdf export?

Hi

I know this has been asked before, but I can't find it...

I would like to export a document which contains graphs generated in R
as html as well as latex / pdf. For LaTeX, I use output format pdf,
d=which does not work as inline picture for html export. How can I
automate the process, that all graphs which are included in org as e.g.

--8<---------------cut here---------------start------------->8---
#+begin_src R :file graph.pdf :results graphics
  plot(1,1)
#+end_src

#+RESULTS:
[[file:graph.pdf]]
--8<---------------cut here---------------end--------------->8---

are available for the html export as inline images (e.g. png)?

I remember some use of imagemagic? 

I could obviously do this manually in each code block, but I would
prefer a general solution, so that I can forget about it and it is working.

Thanks,

Rainer

Hi Rainer,

One option is to use svg graphics, which are supported in latex (via the
svg package from CTAN) and in HTML (on almost all modern browsers:
<http://caniuse.com/#feat=svg>).  The svg latex package supports
compiling with pdflatex out of the box and lualatex with a little
hackery; xelatex is not supported (you also need to install inkscape and
compile with a flag that allows latex code to execute shell commands).

Otherwise, you might be looking for something like this worg page:
<http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-LaTeX.html#sec-4-3>.

And also search “by-backend” in the mailing list archives for other
relevant examples.

Hope this is helpful,

svg does not work easily, as I have to use the cairo package in R to use
it, so I have to add this manually. Nevertheless, I could do this in a
session in a block before.

That one works nicely when generating the graphs on export - but I
would like to do no evaluations on export to have the org file as a
"output" itself.

Thanks a lot,

Rainer

OK - ignore my comment concerning R - this is working. I am just trying
it out. HTML works perfectly. 

I am just struggling with pdf. I have to set the org-latex-pdf-process
to "pdflatex -shell-escape -interaction nonstopmode -output-directory %o
%f" and, due to security concerns, only want to set it via file local
variable. But I somehow don't manage it.

,----
| # Local Variables:
| # org-latex-pdf-process: "pdflatex -shell-escape -interaction nonstopmode -output-directory %o %f"
| # End:
`----

Does not work ("No valid command to process pdf"). How can I set the
command as a file local variable?

maybe as list like here:

% reftex-ref-style-default-list: ("Fancyref")

Perfect - working.

Thanks a lot,
