Graphics, Figures & Tables ⇒ help with animate package and tikz

[fenghedo]

Hi all,

I have the following code that TeXnicCenter has been complaining "Package animate error: contents of first frame must not have zero width." I have no idea what is wrong. Please help.

Code: Select all

\documentclass{beamer}
\usepackage{tikz}
\usepackage{animate}

\usetikzlibrary{mindmap,trees}

\begin{document}

\begin{frame}
	\frametitle{test animation}
	\begin{animateinline}[controls,
	begin={\begin{tikzpicture}},
	end={\end{tikzpicture}}]{10}
		\path[remember picture,overlay,mindmap,concept color=red!50]
		node[concept,shift={(2cm,1cm)}] at (current page.west) {My first line};
		\newframe
		\path[remember picture,overlay,mindmap,concept color=red!50]
		node[concept,shift={(2cm,1cm)}] at (current page.west) {My second line};
		\newframe
		\path[remember picture,overlay,mindmap,concept color=red!50]
		node[concept,shift={(2cm,1cm)}] at (current page.west) {My 3rd line};
	\end{animateinline}
\end{frame}

\end{document}

Any ideas?

Hi,

I did some tests and discovered that the use of the overlay option was problematic (creates an empty frame); if you suppress that option, your code compiles OK (although I don't know if it will still produce the desired result):

Code: Select all

\documentclass{beamer}
\usepackage{tikz}
\usepackage{animate}

\usetikzlibrary{mindmap,trees}

\begin{document}

\begin{frame}
   \frametitle{test animation}
   \begin{center}
   \begin{animateinline}[controls,
   begin={\begin{tikzpicture}},
   end={\end{tikzpicture}}]{1}
     \path[remember picture,mindmap,concept color=red!50]
      node[concept,shift={(2cm,1cm)}] at (current page.west) {My first line};
      \newframe
      \path[remember picture,mindmap,concept color=red!50]
      node[concept,shift={(2cm,1cm)}] at (current page.west) {My second line};
      \newframe
      \path[remember picture,mindmap,concept color=red!50]
      node[concept,shift={(2cm,1cm)}] at (current page.west) {My 3rd line};
     \end{animateinline}
   \end{center}
\end{frame}

\end{document}

Thanks gmedina for your reply. I did try your suggestion with a somewhat more complicated plotting. However, after the compile, I get a blank page. So I am giving up on this idea of using animate package. I tried the beamer animate command and it worked, although that gives us a lot more pages and the coding is a little bit too tedious (you have to use \only <n-> for each page and my animation gives me like 90 pages.
