# problems with tikz and arabi package

I have some problems and I hope you can help me.

When I put a tikzpicture and use the arabi package, the picture is not displayed in the dvi or pdf file, and this without a single error.

I have a solution for that (which I don't like), I have to put the TikZ picture inside an english language environment, like this :

\begine{otherlanguage}{english}
\begin{tikzpicture}
...
...
\end{tikzpicture}
\end{otherlanguage}


it is a boring solution and not suitable if I want to create environments like boxed theorems, etc.

Here is a sample :

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\documentclass{report}

\usepackage[Latin1, utf8, cp1256]{inputenc}
%\usepackage[T1, OT1, LAE]{fontenc}
\usepackage[english, arabic]{babel}
\usepackage{amsmath, amsfonts, amssymb, amsthm}
\usepackage{tikz}

\renewcommand{\theenumi}{\textLR{\arabic{enumi}}-}
\renewcommand{\labelenumi}{\theenumi}

\renewcommand{\thesection}{\textLR{\arabic{section}} -}
\renewcommand{\thepage}{\textLR{\arabic{page}}}

\begin{document}

\tikzstyle{mybox} = [draw=red, fill=blue!20, very thick,
rectangle, rounded corners, inner sep=10pt, inner ysep=20pt]
\tikzstyle{fancytitle} =[draw=red, fill=blue!20, text=black, rectangle, rounded corners]
\begin{otherlanguage}{english}
\begin{tikzpicture}
\node [mybox] (box){%
\begin{minipage}{.89\textwidth}
\begin{otherlanguage}{arabic}

لتكن $f$ دالة مستمرة على المجال $[a,b]$ و قابلة للإشتقاق على $]a,b[$,
حيث $f(a)=f(b)$.
إذن, يوجد عدد حقيقي $c \in ]a,b[$ حيث
$$f(c)=0$$.
\end{enumerate}
\end{otherlanguage}
\end{minipage}
};
\node[fancytitle, left=10pt] at (box.north east) {\AR{نظـريـة}};
\node[fancytitle, rounded corners] at (box.east) {$\clubsuit$};
\end{tikzpicture}%
\end{otherlanguage}

\begin{center}
\begin{otherlanguage}{english}
\begin{tikzpicture}
\draw[thick,rounded corners=8pt]
(0,0) -- (0,2) -- (1,3.25) -- (2,2) -- (2,0) -- (0,2) -- (2,2) -- (0,0) -- (2,0);
\end{tikzpicture}
\end{otherlanguage}
\end{center}

\end{document}

you can try to compile this code with pdflatex without

\begin{otherlanguage}{english}

\end{otherlanguage}

in the last picture. this picture isn't displayed in the output pdf file.

• ps: there is no enumerate environnement. – singular Jul 16 '13 at 22:24
• yes, it work well for this example. But each time i must use \begin{otherlanguage}{english} tikz picture ... \end{otherlanguage} and inside the tikz picture there is another \begin{otherlanguage}{arabic} Arabic text .... \end{otherlanguage} – singular Jul 16 '13 at 22:50
• Like i said, this is not suitable if i want to creat a good looking boxed environnements like theorems, lemmas... etc – singular Jul 16 '13 at 23:11
• yes, (\end{enumerate}) is removed now. – singular Jul 16 '13 at 23:32

This seems to be due to an incompatibility between TikZ and babel with the arabic option. It can be rectified reasonably easily, though.

To make TikZ work in a document that's using babel with the arabic option, the tikzpicture environment needs to be in an english environment. To automatically switch to english, you can put

\usepackage{etoolbox}
\AtBeginEnvironment{tikzpicture}{\selectlanguage{english}}


To switch to arabic for the text within the tikzpicture, you can put

\tikzset{font=\selectlanguage{arabic}}


into your preamble. The contents of font are executed at the start of each node.

\documentclass{report}

\usepackage[utf8]{inputenc}
\usepackage[english, arabic]{babel}
\usepackage{amsmath, amsfonts, amssymb, amsthm}
\usepackage{tikz}

\usepackage{etoolbox}
\AtBeginEnvironment{tikzpicture}{\selectlanguage{english}}
\tikzset{font=\selectlanguage{arabic}}

\begin{document}

\section{المتتاليات العددية}

\tikzset{
mybox/.style={
draw=red, fill=blue!20, very thick,
rectangle, rounded corners, inner sep=10pt, inner ysep=20pt
},
fancytitle/.style={
draw=red, fill=blue!20, text=black, rectangle, rounded corners
}
}
\begin{tikzpicture}
\node [mybox] (box){%
\begin{minipage}{.89\textwidth}

لتكن $f$ دالة مستمرة على المجال $[a,b]$ و قابلة للإشتقاق على $]a,b[$,
حيث $f(a)=f(b)$.
إذن, يوجد عدد حقيقي $c \in ]a,b[$ حيث
$$f^\prime(c)=0.$$
\end{minipage}
};
\node[fancytitle, left=10pt] at (box.north east) {\AR{نظـريـة}};
\node[fancytitle, rounded corners] at (box.east) {$\clubsuit$};
\end{tikzpicture}%
