[O] patch for latex-tikz
Hi all,
attached is a small patch that makes it possible to 'evaluate' latex
source blocks to tikz files.
When the :file header argument has a value ending in '.tikz' the content
of the body of the source block will be copied into the resulting tikz
file.
This makes handling of tikz figures with captions easier.
Here is a use-case:
--8---cut here---start-8---
#+latex_header: \usepackage{tikz}
* 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 results
#+header: :imagemagick (if (and (boundp 'backend) (eq (org-export-backend-name
backend) (intern latex))) no yes)
#+header: :fit (if (and (boundp 'backend) (eq (org-export-backend-name backend)
(intern latex))) no yes)
#+header: :results raw :file (if (and (boundp 'backend) (eq
(org-export-backend-name backend) (intern latex))) flowdiagram.tikz
flowdiagram.png)
#+header: :headers \\usepackage{tikz}
#+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
[[file:flowdiagram.png]]
--8---cut here---end---8---
This example works well besides some weird scaling/placement issue.
Regards,
Andreas

The best way I've found to deal with scaling/placement of raw or inline
tikz is to use the subcaption and adjustbox packages as in the following
example.
% latex
\begin{figure}
\centering
\begin{minipage}[b]{0.32\linewidth}
\adjustbox{width=1.0\linewidth}{
\begin{tikzpicture}
% ...
\end{tikzpicture}
}
\subcaption{\small part 1}
\end{minipage}
\begin{minipage}[b]{0.32\linewidth}
\adjustbox{width=1.0\linewidth}{
\begin{tikzpicture}
% ...
\end{tikzpicture}
}
\subcaption{\small part 2}
\end{minipage}
\begin{minipage}[b]{0.32\linewidth}
\adjustbox{width=1.0\linewidth}{
\begin{tikzpicture}
% ...
\end{tikzpicture}
}
\subcaption{\small part 3}
\end{minipage}

thanks for the pointer. I was not aware of the adjustbox package
before. Definitely interesting.
Playing with it I found the flaw in my patch. The inclusion of
[[foo.tikz]] is wrapped in \begin{tikzpicture} ... \end{tikzpicture}
already during LaTeX export.
So, exporting my example to latex gives a nested tikzpicture. There is
nothing wrong with that, but the outer tikzpicture has these scaling
options, hence the wrong placement/scaling.
The code block that is going to tikz should, thus, *not* contain
the \begin{tikzpicture} and \end{tikzpicture} directives.
That might not render my patch completely useless, but limits its
use at least.
I was hoping for one and the same latex code block to be evaluated to
tikz/pdf/svg/imagemagick giving (more ore less) the same resulting image
in each.
In the moment that is not the case.
To clarify this:
--8---cut here---start-8---
# can be evaluated to tikz (to export to latex)
#+begin_src latex
picturecontents
#+end_src
# can be evaluated to pdf/svg/imagemagick
#+begin_src latex
\begin{tikzpicture}
picturecontents
\end{tikzpicture}
#+end_src
--8---cut here---end---8---

Andreas
