latex block tikz to svg

[Edouard Debry]

Hello,

I experience some difficulties to export latex src block
consisting of tikz code to svg.

Here is for example the simple code I try to run with `C-c C-c` :

<==================================================>
#+HEADER: :file test1.png
#+HEADER: :imagemagick yes
#+HEADER: :exports results
#+HEADER: :results output silent graphics file
#+HEADER: :headers '("\\usepackage{tikz}")
#+HEADER: :fit yes :imoutoptions -geometry 400 :iminoptions -density 600
#+begin_src latex
\begin{tikzpicture}             %
\draw[->] (-3,0) -- (-2,0) arc[radius=0.5cm,start angle=-180,end angle=0] 
(-1,0) -- (1,0) arc[radius=0.5cm,start angle=180,end angle=0] (2,0) -- (3,0);
\filldraw (-1.5,0) circle[radius=1mm];
\filldraw (1.5,0) circle[radius=1mm];
\end{tikzpicture}
#+end_src
<==================================================>

First of all, for this to work I have to change  `org-latex-pdf-process`
to ("latexmk.exe -pdf -f %f -cd %o"), which unfortunately breaks the
latex to pdf export of org files (C-c C-e l o/p).

Then, it works when image file format is png. However, a close look of
the pdflatex output shows this error :

I wonder why it tries every time to compile a ".tex" file although the
temporary previous pdf file was correctly generated.


Finally, if I change "test1.png" to "test1.svg", such a svg file is
generated but with garbage in it.

I would like to find a way to generate svg images from latex src blocks
(using tikz) which works and is compatible with default orgmode settings
for latex export (at least does not break it)

Did you experience such issues ? do you have some workings settings and
examples ? I googled several times "org latex block tikz svg", but it is
difficult to guess how relevant are the elements found, some of them
seems quiet outdated. Hence my question on this mailing list
