I'am a bit confused by the animate package I compile with LuaTeX. It is a very simple code:
\documentclass{article}
\usepackage{graphicx}
\usepackage{animate}
\begin{document}
\animategraphics[controls]{1}{boot}{01}{11}
\end{document}
and all I want to do is simply switch through the pics (boot01.png to boot11.png) showing them in their original sizes. BUT, after the very first pic (boot01.png), all the other pics come in the same geometry (so, if the first pic is 400 x 100 and the second is 200 x 600, the second will be shown in 400 x 100 too and so on ... completely distorted. There must be an option to prevent this behavior, but I didn't find it. I have found this keepaspectratio, but ... Could anyone give me a hint?
\animategraphics[width=4cm,height=1cm]...
?
