I am writing my thesis presentation using beamer template. I would like to create the following thing:

  • slide 1 -> shows a simple image
  • slide 2 -> shows a different image with a bullet list positioned where i want
  • slide 3 -> same as slide 2

I have red that this can be done by using tikz, but i don't seem to understand how it works. I have used the \only environment for the images and it works, but i need some help for the tikz part. Can any of you give me some tips?

Below the latex code i am working on:

\documentclass{beamer}
\usepackage{amsfonts,amsmath,oldgerm}

\newcommand{\testcolor}[1]{\colorbox{#1}{\textcolor{#1}{test}}~\texttt{#1}}

\usefonttheme[onlymath]{serif}
\usepackage[absolute,overlay]{textpos}
\usepackage{tikz}

\newcommand{\hrefcol}[2]{\textcolor{cyan}{\href{#1}{#2}}}
\begin{document}
\begin{frame}[t]{}
    \only<1>{\begin{tikzpicture}
        \node at (current page.center) {\includegraphics[scale=0.5]{example-image-a}};
    \end{tikzpicture}}
    \only<2->{\begin{tikzpicture}
        {\node at (current page.center) {\includegraphics[scale=0.5]{example-image-a}};
        \node [rectangle, text width=3cm] at (15,9) {\begin{itemize}
 \item item1
 \item item2
 \end{itemize}};
}
\end{tikzpicture}}
\end{frame}

\end{document}

    Welcome. // Which Tikz part do you mean?

    TikZ is a drawing program/language for LaTeX. You must mean something else as you do not write anything about drawing.

  • You don't need the only in your code. It isn't doing anything whatsoever.

  • To combine text and images with tikz, put text in one node and \includegraphics in another node, and place them where you want them relative to each other.

    @MS-SPO I added a tentative code using tikz with the resulting output. Moreover i specify the image to be in the center. Why it is aligned at the left side?

If you want to use page nodes like current page.center you have to use the remember picture option.

I'd either combine this with the overlay option or with visible on=... from the overlay-beamer-styles library to prevent other content of the slide from jumping around between overlays.

\documentclass{beamer}
\usepackage{oldgerm}

\usefonttheme[onlymath]{serif}
\usepackage{tikz}

\begin{document}
\begin{frame}[t]{}
   \begin{tikzpicture}[remember picture,overlay]
     \node<1-> at (current page.center) {\includegraphics[scale=0.5]{example-image-a}};
     \node<2->[rectangle, text width=3cm] at (10,-3) {
        \begin{itemize}
           \item item1
           \item item2
         \end{itemize}
     };
\end{tikzpicture}
\end{frame}

\end{document}

  • Thank you very much. Now the image is positioned in the center of the slide. Now i am trying to add a bullet list to the image side but it gives me the error: LaTeX Error: Something's wrong--perhaps a missing \item. I edited the original code with the new one. Can you give me some advices?

  • Ok thank you i will accept this answer. If you can i would like to ask you another question. What i would like to do is to have in the first slide an image centered (example-image-a) for example, while in slide 2 i would like to have example-image-b with the bullet list. I have to create another \begin{}/end{} tikzpicture or i can include everything inside the one i already have?

  • @AndreaTantucci If you want image a only on the first overlay, use \node<1> ... and then \node<2-> ... with another image
