## Animating TikZ Graphics

After drawing the cubic Bezier a few days ago I wanted to animate it. Using the animate package this is fairly simple:

\documentclass{article} \usepackage[paperwidth=5.5cm,paperheight=5.3cm,left=0cm,right=0cm,bottom=0cm,top=0.25cm]{geometry} \usepackage{tikz} \definecolor{fom}{RGB}{0,153,139}   \newcommand{\dat}{0.7} % 0.67 \usepackage{animate}   \begin{document}   \begin{animateinline}[poster=last, controls, palindrome]{10} \multiframe{70}{Ry=0.1+0.01}{ \begin{tikzpicture}[x=4cm,y=4cm] \draw[line width=1pt,lightgray] (0,0) -- (1,1); \draw (0,0) -- (1,0) -- (1,1) -- (0,1) -- (0,0); \draw (0,0) -- (0.17,0.67); \draw (1,1) -- (0.83,\Ry);   \draw [magenta,fill=magenta](0.17,0.67) circle (.5ex); \draw [fom,fill=fom](0.83,\Ry) circle (.5ex);   \draw[line width=1pt] (0,0) .. controls (0.17,0.67) and (0.83,\Ry) .. (1,1);   \node[label={[label distance=0.0cm,text depth=-1ex,rotate=90]left:Fortschritt in \%}] at (-0.1,.8) {}; \node[label={[label distance=0.0cm,text depth=-1ex]right:Zeit-Achse}] at (0,-0.05) {}; \end{tikzpicture}} \end{animateinline}   \end{document}

I am animating in the TeX code (not externally) so I use animateinline with 10 frames per second. Inside this environment I prepare 70 frames, where I have the y-coordinate of the second point loop from 0.1 in steps of 0.01. The looping is controlled via Ry (that translates to \Ry in the loop). That’s it!

Here is the resulting PDF: bezier

PS: I used pdflatex from the TeX Live 2014.
