[Tex/LaTex] Inserting a portrait page into landscape presentation using beamer

Question

I am doing the presentation of my PhD using beamer. I have done the diagram flux of my algorithm and I want to show it in my presentation. The problem that I have is that when I wrote down the diagram flux in my phd_doc.tex file I didn't have any problem because the orientation of it was portrait.

But when I use the same LaTeX code of the diagram flux into beamer.tex file I have the problem of the orientation.

I would like to know how I can change the orientation (landscape) of a single frame in beamer into portrait? Because as I know, the orientation default in beamer is landscape.

Answer 1

Also with beamer you could use the landscape environment of the lscape or the pdflscape package for changing the frame orientation - this time to portrait, since landscape is the default.

For example:

\documentclass{beamer}
\usetheme{Rochester}
\title{The title}
\subtitle{A subtitle}
\author{Author}
\institute{TeX LaTeX StackExchange}
\date{\today}
\usepackage[english]{babel}
\usepackage{blindtext}
\usepackage{pdflscape}
\begin{document}
\maketitle
\begin{landscape}
  \begin{frame}
    \frametitle{Landscape}
    \begin{itemize}
      \item Some blindtext
      \item \blindtext
      \item more
      \item and
      \item more
      \item text
    \end{itemize}
  \end{frame}
\end{landscape}
\begin{frame}
\blindtext
\end{frame}
\end{document}
