Adding a tikz picture to every slide in a beamer presenation

Question

I have a tikz drawing I would like to add to every slide in my beamer presentation. Presenly I have to add it manually to every slide - a bit tedious! Is there a way of using a \newcommand to do this automatically?

The code for the tikz image is :

\begin{tikzpicture}[remember picture,overlay]
     \draw [line width=2mm,MyColor] (current page.south east) rectangle (current page.north west);
\end{tikzpicture}

Cheers!

Answer 1

If you don't mind if it's covered by other text, you can place the picture into the background template.

\documentclass{beamer}
\usepackage{tikz}

\usebackgroundtemplate{
    \tikz \draw[line width=2mm, red] ([shift={(1mm,1mm)}]current page.south west) rectangle ([shift={(-1mm,-1mm)}]current page.north east);}

\begin{document}
\begin{frame}
Test
\end{frame}
\end{document}

\documentclass{beamer}

\usepackage{tikz}

\logo{%
    \begin{tikzpicture}[remember picture,overlay]
        \draw [line width=2mm,black] (current page.south east) rectangle (current page.north west);
    \end{tikzpicture}
}

\begin{document}

    \begin{frame}
        abc
    \end{frame} 

\end{document}
