beamergraphics
The following code:
\frame[plain]
{
\frametitle{}
\includegraphics[scale=0.75]{1.jpg}
}
is resulting in an image which is offset to the right. The left margin is larger than the right margin. Wrapping the \includegraphics in a figure or center environment does not solve the problem.
How can I center the image in beamer?
One basic idea could be use a minipage and divide it in two columns: on the right put the image and on the left the text. This method is not perfect, but gives you at least something similar to a wrapped figure.
Here is my code with a test image:
\documentclass[11pt,t,handout]{beamer}
\usepackage{graphicx}
\usetheme{EastLansing}
\author{Max Mustermann}
\begin{document}
\begin{frame}
\frametitle{Folientitel}
\begin{minipage}[0.2\textheight]{\textwidth}
\begin{columns}[T]
\begin{column}{0.8\textwidth}
\begin{itemize}[<+->]
\item Punkt 1 = text blah blah foo bar, text blah blah foo bar, text blah blah foo bar
\item Punkt 2= text blah blah foo bar, text blah blah foo bar, text blah blah foo bar
\item Punkt 3= text blah blah foo bar, text blah blah foo bar, text blah blah foo bar
\end{itemize}
\end{column}
\begin{column}{0.2\textwidth}
\includegraphics[width=2.5cm]{logopolito}
\end{column}
\end{columns}
\end{minipage}
\begin{itemize}[<+->]
\item Punkt 1 = text blah blah foo bar, text blah blah foo bar, text blah blah foo bar
\item Punkt 2= text blah blah foo bar, text blah blah foo bar, text blah blah foo bar
\item Punkt 3= text blah blah foo bar, text blah blah foo bar, text blah blah foo bar
\end{itemize}
\end{frame}
\end{document}
which gives you as result:
Try this:
\documentclass{beamer}
\usepackage[absolute,overlay]{textpos} %for positioning
\usepackage{tikz} %for transparency
\newenvironment{reference}[2]{% %
\begin{textblock*}{\textwidth}(#1,#2) % creates the reference environment
\footnotesize\it\bgroup\color{red!50!black}}{\egroup\end{textblock*}} %
\usetheme{Goettingen}
\begin{document}
\begin{frame}
\begin{reference}{108mm}{70mm}
\tikz\node[opacity=0.4]{\includegraphics{yourjpeg.jpg}};
\end{reference}
\frametitle{Title}
Content
\end{frame}
\end{document}
The solution is based on the tetxpos and TikZ packages. It produces this:
you need to insert the location of you jpeg image and change the reference values according to its size. The beamer slide is 128*96mm. You may also need to scale your jpeg \includegraphics[scale=<value>]
If you instead want the jpeg to appear in every frame, then add this code in the preamble
\setbeamertemplate{sidebar left}{
\begin{reference}{108mm}{70mm}
\tikz\node[opacity=0.4]{\includegraphics{yourjpeg.jpeg}};
\end{reference}
}
notice the sidebar left template. It must be on the opposite side with respect to where your navigation sidebar is, otherwise it will overwrite it.
Best Answer
If you insist on using
scalekey, then find the best value for it. Varying the value in a closed interval (as shown in the following animation) can help you find the best value for thescalekey.
