Hello again,

I am trying to get an example that worked with the old exporter to work
with the new exporter.  The aim is to have a tikzpicture exported to
both LaTeX and HTML.  The example is in the following message from over
a year ago now:

http://article.gmane.org/gmane.emacs.orgmode/53900

This example no longer works for either LaTeX or HTML.  For LaTeX, I
would expect the actual tikz code to be inserted into the LaTeX file and
then processed.  Instead, I get the file name in a verbatim
environment.  For HTML, I would expect the image referred to from an
<img> tag but I get a link to the test.png file instead.

The actual test.png file is created in both cases.

Is what I want possible with the new exporter?  If so, I imagine the
test for the backend must be different now.  Any pointers very welcome!

Thanks,
eric

Tikz/pgf works for the latex exporter.  Just insert it as a file link
(with extension tikz or pgf) or as latex verbatim code.

It should be an svg since tikz is a lossless format IMO.

Here's a very rough and ugly function to translate tikz to svg.  I
don't know if there's a more direct approach. . .

#+BEGIN_SRC emacs-lisp
(defun tikz-to-svg (file &optional headers standalone-ops)
  "Convert a tikz picture to a svg picture ready for html
output.

Headers is a string like
 '(pgfplots '(calc tikzlibrary) (kpfonts usepackage oldstylenums). 
Do not include tikz in headers.

Set standalone-ops to t if you want to use the standalone packages conversion.
"
  (let* ((name (file-name-sans-extension (file-name-nondirectory file)))
         (fname (concat "/tmp/" name))
         (fnamet (concat fname ".tex"))
         (final (concat (file-name-directory file) name ".svg"))
         )
    (with-temp-file fnamet
      (insert (format "\\documentclass[tikz,%s]{standalone}\n"
                      (if (not standalone-ops) ""
                        (if (eq t standalone-ops) 
                            "convert={outfile=\jobname.svg}" standalone-ops))))
      (when headers
        (insert
         (mapconcat (lambda (x)
                      (cond ((stringp x) (format "\\usepackage{%s}" x))
                            ((and (listp x) (= 2 (length x)))
                             (apply 'format "\\%s{%s}" (reverse x))
                             )
                            ((and (listp x) (= 3 (length x)))
                             (funcall 'format "\\%s[%s]{%s}"
                                      (second x) (third x) (first x))
                             (t "")

      (insert "\n\\begin{document}\n")

    (call-process "pdf2svg" nil "*tmp*" nil (concat fname ".pdf") (concat fname ".svg"))
    (rename-file (concat fname ".svg") final t)
    (if (file-exists-p final)
        (format "[[file:%s]]" final)
      ""

      )))

It needs to be added to `org-html-inline-image-rules' and some
potential translation should be added to org-html-inline-image-p,
e.g. substitute pgf or tikz with whatever is the output format.
Perhaps the dvipng code in ox-html can utilized to obtain a png
seemingly.

Actually, dvisvgm might be way to go as it may be possible to leverage
upon all of the dvipng code without much loss of generality.  It would
also be useful for equations where one does not want to use mathjax.
It's only packed for Texlive, though.

And did anybody tried the svg backend available from tikz, rather than
relying
on pdf conversion?

Yes, thanks.  However, I guess I didn't explain very well what I was
looking for.  

I use tikz all the time and typically enclose it in a #+begin_LaTeX
... #+end_LaTeX block.  That is fine for most of my documents where I
only wish to export to PDF via LaTeX.

However, what I would like is to be able to use the same code, inline
within the org file and not as a separate .tikz file, in some cases to
export to both LaTeX and HTML (or ODT for that matter).  The code in the
link I posted used to do this by dynamically setting the :exports and/or
:results options using org babel headers with emacs lisp code.  A
variation of this worked with the old exporter but doesn't with the new
one.

Thanks again,
eric

I updated the example again.  Try this:

#+LATEX_HEADER: \usepackage{tikz}

#+name: contents
#+header: :exports (if (and (boundp 'backend) (eq (org-export-backend-name backend) (intern "latex"))) "results" "none")

Building from this example, the attached patch to ob-latex.el combined
with the attached org-mode file should export the latex (tikz) code as
an inline SVG image to HTML and as embedded tikz to latex.

If this works generally I can commit the patch to ob-latex.el.

Brilliant.  Thanks.  This works perfectly.  I can see the changes you've
made and they make sense (in hindsight for me) except for the (intern
"latex") bit... but this is probably to do with how eq works I guess.

Anyway, thanks again.

Looks good to me, although it would make ox-html depend on ox-latex
which may or may not be desirable. . .  For instance math stuff is
handled internally by ox-html, it seems (correct me if I'm wrong).
While TikZ clearly is a LaTeX feature, producing SVGs are more of a
way of support this type of figures in html output, although it
depends on TeX binaries.

File links to tikz files [[file:pix.pgf]] (e.g. produced with R or
matplotlib) won't be understood with this patch.  It should
automatically convert the picture to an svg figure, I think.  Perhaps
support for file links can be added later.

This is very nice and works well for me.  I would very much like to see
that in orgmode.  Thanks a lot!

How do I extend your example to output latex for latex, svg for html and
png in all other cases?

I tried that simple combination with my previous example, which failed:

#+header: (by-backend (html 'nil) (latex 'nil) (t :imagemagick yes :iminoptions -density 600 :imoutoptions -geometry 400 :fit yes :noweb yes :headers '("\\usepackage{tikz}")))

I actually dropped the intern bit from the previous approach.

I'm happy this looks useful, I will go ahead and commit.

Nope, this patch only touches ob-latex not ox-latex (easily mistaken

Correct.  I think that users of R or gnuplot should use R or gnuplot to
produce SVG or PDF images directly.  I don't think htlatex makes sense
in those use cases.

Great, I've just committed this patch.  Thanks for your original example
which this simply extends.

The attached does this.  The catch is that the :imagemagick header
argument is required for png (and other) image types to be used.

thanks for the quick answer.  I am aware, that imagemagick is needed.
Let me rephrase my question using your example:

I seem not to be able to apply (by-backend ) at the 'top-level, like so:

#+header: (by-backend (html 'nil) (pdf 'nil) (t ":imagemagick"))

Why is that?

Andreas

Because elisp evaluation is available for header argument *values*, not
for the entire header argument line.  Instead you could do the
following, or just use the example in my previous email which sets
:imagemagick in all cases.

    #+header: :imagemagick (by-backend ((html pdf) 'nil) (t "yes"))

Thanks for this Eric!  I've tried it out just now (on a real document)
and it works well.

I do have a problem in the SVG creation in that I need a special package
included to generate the figure in question.  Time to search on the list
as I think this has come up before for LaTeX snippets.

Thanks again,
eric

My patch introduced a new variable `org-babel-latex-htlatex-packages'
which controls the packages added to these latex to SVG code block
snippets.  The following should work.

  (push "{your-package}" org-babel-latex-htlatex-packages)

Yes, thanks, I found this soon afterwards by carefully reading your
previous email!

I still have some problems but I think they are due to my various other
customisations.

Thanks again,

Hi Eric et al.,

I now have a system I am happy with mostly for using LaTeX code blocks
heading to multiple export targets.  The solution I am using is a
combination of what has been discussed in this thread (by-backend
customisation of headers for babel) and using noweb substitution for the
main content.  I have two LaTeX babel source blocks, one for PDF export
and the other for HTML export.  Each of these has a tikzpicture
environment which then includes the actual instructions for drawing
brought in using noweb.

The problem I have remaining is how to get the version used to export to
PDF via LaTeX to use a figure environment with captioning.  I had
thought that something along these lines would work:

#+begin_src org
  ,#+name: picturecontents
  ,#+begin_src latex :noweb yes :exports none
    \node[red!50!black] (a) {A};
    \node (b) [right of=a] {B};
    \draw[->] (a) -- (b);
  ,#+end_src
  
  ,#+name: flowdiagram
  ,#+header: :exports (if (and (boundp 'backend) (eq (org-export-backend-name backend) (intern "latex"))) "results" "none")
  ,#+header: :results latex
  ,#+header: :noweb yes
  ,#+begin_src latex
    \begin{tikzpicture}
      <<picturecontents>>
    \end{tikzpicture}
  ,#+end_src
  
  ,#+caption: Testing figure caption for figure going to multiple destinations
  ,#+results: flowdiagram
#+end_src

as I expected the export to put the results of the flowdiagram code
block after the results line.  This doesn't work: the exported LaTeX
has no figure environment etc.  The diagram does come out but it is
placed directly into the document.

I hope this all makes sense?  Any suggestions?

thanks,
eric

I actually think, that it would be cool, if latex supported the tikz
output as R does.

But since you have a dedicated latex export-only block, the simplest
solution would be to put the caption inside:

--8<---------------cut here---------------start------------->8---
#+latex_header: \usepackage{tikz}
#+latex_header: \usepackage{hyperref}

* Test

#+name: picturecontents
#+begin_src latex :noweb yes :exports none
 \node[red!50!black] (a) {A};
 \node (b) [right of=a] {B};
 \draw[->] (a) -- (b);
#+end_src

#+name: flowdiagram
#+header: :exports (if (and (boundp 'backend) (eq (org-export-backend-name backend) (intern "latex"))) "results" "none")
#+header: :results latex
#+header: :noweb yes
#+begin_src latex
  \begin{figure}
   \begin{tikzpicture}
     <<picturecontents>>
   \end{tikzpicture}
   \caption{Testing figure caption for figure going to multiple destinations}
  \end{figure}
#+end_src
--8<---------------cut here---------------end--------------->8---


Regards,
Andreas

D'uh!  That is so obvious (in hindsight ;-) <blush>...  thanks!
