# Inserting a portrait page into landscape presentation using beamer

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.

If you do this, the page will display incorrectly in the presentation. The projector won't turn round to fit the page orientation. So the page itself probably shouldn't be changed, what should change is how your diagram fits on the page. If you could post the code or upload a picture that would help us see what the problem is. (As you're new to this site then to upload a picture, click the icon that looks vaguely like a picture and follow the instructions. Then remove the exclamation mark from the code that's been automatically inserted.) –  Loop Space Nov 2 '11 at 13:19
In order to display a beamer-formatted page in portrait mode, one would have to rotate the projector by 90 degrees (and do something with the screen too, in all likelihood). Incidentally, while it's usually OK to list an algorithm's pseudo-code on a single page, this is not the case when giving presentations (using beamer or any other display method). Unless your audience is already thoroughly familiar with the algorithm in question, you should work hard to break it up into smaller chunks (each with probably no more than 7 or 8 lines) and then show these smaller chunks, one per beamer page. –  Mico Nov 2 '11 at 14:38
Here is a (positive) suggestion: Post your "diagram flux" in portrait mode, shrunk down to fit in your landscape presentation, and use beamer's zooming capability to click on the "diagram flux" and zoom to fit. –  Werner Nov 3 '11 at 5:29

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}

Is there a way to preserve the all other elements (navigation buttons, blue frame) as in landscape while rotating the content to portrait? –  Majoko Aug 19 '14 at 15:37
