Page Layout ⇒ beamer | Overlay Area

[mamboreina79]

Hello, I have a problem with the overlayarea environment in "beamer". I don't know if I am not getting what it does, but I understood that it helps to keep the content inside from jumping when the content heights are different.

However, when I use it the content jumps from slide to slide. Here is the code I am using:

Code: Select all

\documentclass[10pt,compress,professionalfonts]{beamer} 
\usepackage[english]{babel}
\usepackage[scaled]{helvet}
\usepackage[T1]{fontenc}
\usepackage[charter]{mathdesign}

\begin{document}

\begin{frame}{Pandemonium}
\begin{overlayarea}{\textwidth}{\textheight}

\begin{onlyenv}<1-2>\includegraphics[width=\textwidth]{pande1.eps}\end{onlyenv}
\begin{onlyenv}<3-> \includegraphics[width=\textwidth]{pande2.eps}\end{onlyenv}

some text

\end{overlayarea}
\end{frame} 

\end{document}

I have also tried with a figure environment:

Code: Select all

\begin{figure}
  \includegraphics<1-2>[height=0.4\textheight]{pande1.eps}
  \includegraphics<3-> [height=0.4\textheight]{pande2.eps}
\end{figure}

I attach the two figures. What I am doing wrong?

Hi,

the overlayarea environment keeps its size regardless of its actual contents. Obviously you would like to put the pictures in this area, which is fine. Within the environment, positions can change, depending on the content. The outside of the area would not be affected though.

So if you simply put the some text after the environment has ended, this text would not jump. Of course you have to reduce the height of the overlayarea.

Code: Select all

\documentclass[10pt,compress,professionalfonts]{beamer}
\usepackage[english]{babel}
\usepackage[scaled]{helvet}
\usepackage[T1]{fontenc}
\usepackage[charter]{mathdesign}

\begin{document}

\begin{frame}{Pandemonium}
\begin{overlayarea}{\textwidth}{.4\textheight}

\begin{onlyenv}<1-2>\includegraphics[width=\textwidth]{pande1.eps}\end{onlyenv}
\begin{onlyenv}<3-> \includegraphics[width=\textwidth]{pande2.eps}\end{onlyenv}

\end{overlayarea}
some text
\end{frame}

\end{document}
