# Picture and animateinline

I would like to have an animation (consisting of three pictures pic-0.jpg, pic-1.jpg, pic-2.jpg) with additional elements added on the top of the animation. What am I doing wrong? And how can I do it right?

\documentclass[xcolor={dvipsnames,svgnames,table},11pt]{beamer}
\usepackage{animate}
\begin{document}
\begin{frame}

\only<1>{Text}
\only<2>
{\begin{animateinline}[autoplay,loop]{6}
\multiframe{3}{i=0+1}{
\begin{figure}[h!]
\centering
\setlength{\unitlength}{0.1\textwidth}
\begin{picture}(0,0)
\put(-6,-3){\includegraphics[height=0.8\columnwidth]{pic-\i} }
\put(4.5,-2){$x$}
\end{picture}
\end{figure} }
\end{animateinline}      }

\end{frame}
\end{document}

• Several issues: (1) figure environment inside animateinline environment; (2) zero picture size – AlexG Jan 31 '18 at 14:09
• Thanks. I got rid of the issues. I still does not work. – Markow Jan 31 '18 at 23:05
• The error is: package animate error content of first frame must not have zero width – Markow Jan 31 '18 at 23:06

1. \begin{picture}(0,0) ... \end{picture} produces a box with zero dimensions, but animate wants non-zero size boxes in order to produce animation frames.

TikZ is better suited for annotating external graphics files. Dedicated TikZ-based packages exist for image annotation, e. g. callouts on CTAN, and non-CTAN onimage, introduced ↗here. I prefer the latter. It can be downloaded as onimage.dtx↗here. Run pdflatex twice on it to get onimage.sty and the documentation onimage.pdf.

1. The figure environment should be moved out of the animateinline environment.
