[Tex/LaTex] Animating TikZ without beamer

animationstikz-pgf

I have the following code:

\documentclass{beamer}

\usepackage{tikz}
\usetikzlibrary{calc}

\begin{document}

\begin{frame}
  \begin{tikzpicture}
    \fill[white] (1,1) circle (2pt);
    \foreach \n in {1,2,...,10}{
      \pgfmathsetmacro{\ang}{(10-\n)*90/10}
      \draw<\n>[thick,dashed,->] (1,0) node[below]{%
        Rotating by $90^\circ$%
      } arc (0:\ang:1);
    }
    \end{tikzpicture}
\end{frame}

\end{document}

Which yields a nice(?) animation of a growing arrow. Now, I want to generate one PDF file where each page contains one cropped slide – as if I was using standalone. Cropped means for me that it will contain only the result of the tikz environment, and nothing else (not even border or something like that).

I tried to use standalone with the multi=true but then it doesn't crop the page, and I don't know how to generate a loop there…

What is the best way to do it?

Best Answer

E. g., by means of the preview package.

Instead of placing an invisible dot at the top edge you could use something like

%\fill[white] (1,1) circle (2pt);
\useasboundingbox (-0.25,-0.45) rectangle (2.2,1.05);

to fine-tune the picture bounding box.

\documentclass{article}

\usepackage[active,tightpage]{preview}
\usepackage{tikz}
\usetikzlibrary{calc}

\PreviewEnvironment{tikzpicture}

\begin{document}

\foreach \n in {1,2,...,10}{%
  \begin{tikzpicture}
    \fill[white] (1,1) circle (2pt);
    \pgfmathsetmacro{\ang}{(10-\n)*90/10}
    \draw[thick,dashed,->] (1,0) node[below]{%
      Rotating by $90^\circ$%
    } arc (0:\ang:1);
  \end{tikzpicture}%
}

\end{document}
