Bounding box is not set properly with arrows

[Christophe Jorssen-2]

Hello,

Consider the fellowing example (save the file as test.tex). The arrows
do not show up because (I think) of a bad bounding box. Is there a way
to fix it ?

Thanks in advance.

\documentclass{minimal}

\usepackage{tikz}
\usetikzlibrary{external}
\tikzexternalize{test}

\begin{document}

\tikzset{external/remake next}
\begin{tikzpicture}
   \draw[<->,very thick] (0,0) -- (2,0);
\end{tikzpicture}
\end{document}

Yes there is a problem with bounding box

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{tikzpicture}
   \draw[<->,very thick] (0,0) -- (2,0);
     \draw[<->,very thick,red] (-0.5,1) -- (3.5,1);
\end{tikzpicture}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
"bricolage"


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\documentclass{minimal}

\usepackage{tikz}
\usetikzlibrary{external}
\tikzexternalize{test}

\begin{document}

\tikzset{external/remake next}
\begin{tikzpicture}
\path[use as bounding box] (0,-.25) rectangle (2,.25);
\draw[<->,very thick] (0,0) -- (2,0);
\end{tikzpicture}
\end{document}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


But the problem exists also with


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\documentclass{minimal}

\usepackage{tikz}
% \usetikzlibrary{external}
% \tikzexternalize{test}
\usepackage[active,pdftex,tightpage]{preview}
\PreviewEnvironment[]{tikzpicture}
\begin{document}

% \tikzset{external/remake next}
\begin{tikzpicture}
% \path[use as bounding box] (0,-.25) rectangle (2,.25);
\draw[<->,very thick] (0,0) -- (2,0);
\end{tikzpicture}
\end{document}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
