I am looking for a way so that Beamer Presentation will be tiling the image background using module \usebackgroundtemplate
?
So far, this gives a background, but of course, it won't tile (mosaic like) the image.
It should be well widely portable (avoiding the cumbersome multido, which isn't installed on any tex installation!).
\documentclass[bigger]{beamer}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{graphicx}
%Global Background must be put in preamble
\usebackgroundtemplate{\includegraphics[width=\paperwidth,height=\paperheight]{newton.jpg}}
\begin{document}
\begin{frame}{Introduction}
\begin{itemize}
\item 1
\item 2
\item 3
\end{itemize}
\end{frame}
\end{document}
Thank you
