For adding an existing PDF to a beamer document, it was explained to use \includepdf with the following code:
\documentclass{beamer}
\usepackage{pdfpages}
\usetheme{Montpellier}
\addtobeamertemplate{navigation symbols}{}{%
\usebeamerfont{footline}%
\usebeamercolor[fg]{footline}%
\hspace{0.5cm}%
\raisebox{1.5pt}{\insertframenumber/\inserttotalframenumber}
}
\begin{document}
{
\setbeamercolor{background canvas}{bg=}
\includepdf{filea.pdf}
}
\end{document}
This way, however, no frame is created and thus, the page (or frame) isn't counted for the numbering in the bottom right (I have two pages 0/20). Since this defies the purpose of numbering at a presentation, I'd like to change this.
\addtocounter{frame}{20}
(whatever number of external pages you include)framenumber
and notframe
