Embedded Tikz Picture

Embedded Tikz Picture

[Julien Cubizolles]

What would be the best way to use some tikz code in an org-file ?

I've succeeded so far by putting it in a 
#+BEGIN_LaTeX
#+END_LaTeX
structure but from what I understand, this code will only be evaluated
when I export to LaTeX.

I also tried embedding the corresponding LaTeX code, but I only got a
white square for the picture. I guess the relevant packages weren't
loaded. Is it possible to make the embedded LaTeX code use the class
defined by #+LATEX_CLASS ?

Finally it seems Babel could be the way to go but I'm not sure what it
offers for LaTeX source with respect to Embedded LaTeX in this case.

Thanks for your help. I'm trying to make the switch to Orgmode for all
my LaTeX needs and it's quite a steep learning curve.

Julien.

I actually just added this example to worg today, it should answer your
question.

Thanks, I don't need the html export for now (although your example
makes me want to try it) but I guess one could adapt it to display the
corresponding png or pdf image in the org file.

I don't know what the best way is.

That's right, (maybe beamer too?).

Could this be a problem with different paper sizes?  If so, the use of
the standalone class (see below) may fix this.

That should be happening already.

I had been using tikz like this, (note: this may not work and my
intention is not to preclude your ECM):

#+LATEX_HEADER: \usepackage{standalone}
#+LATEX_CLASS: report

#+begin_latex
\begin{figure}[htb]
\centering
\includestandalone[mode=tex,width=5cm]{/home/myles/docs/repo/ve/tex/axisymm}
\caption[1D and axisymmetric model domains]{\label{figure:axisymm}1D model domain and mesh of line elements
(left), and the axisymmetric variant (right) showing the increased
element volumes associated with the line elements.}
\end{figure}
#+end_latex

And then in /home/myles/docs/repo/ve/tex/axisymm.tex :

------------------------------------------------------
\documentclass{standalone}
\usepackage{subfig}
%\usepackage[pdftex,active,tightpage]{preview}
%\setlength\PreviewBorder{2mm} % use to add a border around the image

\usetikzlibrary{shapes,arrows,fit,positioning,backgrounds}
\usetikzlibrary{decorations.pathreplacing} % for braces

\begin{document}
%\begin{preview}
\tikzset{Model axes/.style={color=blue!50,->}}

\begin{tikzpicture}[scale=3,
  %\basicBAxes;

\node (one) at ( 0.25,0.8) [place] {};
  \node (two) at ( 0.35,0.8) [place] {};
  \node (three) at ( 0.55,0.8) [place] {};
  \node (four) at ( 0.8,0.8) [place] {};
  
  \draw (one)--(four);
\end{tikzpicture}
\qquad
\begin{tikzpicture}[scale=3,
  %\basicBAxes;
  % arcs
  % dots
  place/.style={circle,draw=black,fill=black,
    inner sep=0pt,minimum size=1mm}]

  % back

  % horseshoe ends
  \draw[Domain boundary] (-90:0.8) -- (-90:0.25);
  \draw[Domain boundary] (90:0.8) -- (90:0.25);

  \node (two) at ( 0.35,0) [place] {};
  \node (three) at ( 0.55,0) [place] {};
  \node (four) at ( 0.8,0) [place] {};
  
  \draw (one)--(four);

  %\draw[Element boundary] (two) arc (0:90:0.35);
  %\draw[Element boundary] (two) arc (0:-90:0.35);

  \draw (two) arc (0:-90:0.35);
  \draw (three) arc (0:90:0.55);
  \draw (three) arc (0:-90:0.55);
\end{tikzpicture}

%\end{preview}
\end{document}

Hi Myles, and thanks for your input. I've also been playing with
standalone, and successfully got the pictures when exporting to latex
and beamer.

Does this allow you to get the picture displayed in the org-mode ?
