[Tex/LaTex] beamer: how to use \pause with textblock* environment

beamerfloatspause

I'd like to show the parts of my slides one after the of the other. I found the \pause command, but it doesn't work with my graphics, which are in the textblock* environment for being in the position they are supposed to be because that was the only solution I could find.

When I have a slide with\pause, the figures (graphics) appear all before the first \pause can "show" them. It feels like they ignore that command.

\documentclass[10pt]{beamer}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}
\usepackage{lmodern}
\usepackage{ngerman}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{textcomp}
\usepackage{lipsum}
\usepackage{gensymb}
\usepackage[absolute,overlay]{textpos}
\usepackage{graphicx}

\begin{document}
\begin{frame}
    \frametitle{Try 1}
    \begin{textblock*}{\textwidth}(0.8\textwidth,1cm)%specific position, I hope the numbers cannot matter...
        \includegraphics[width=4cm,keepaspectratio]{tryone.eps}
    \end{textblock*}\vfill\pause
\lipsum[1]
\pause
\lipsum[2]
\end{frame}
\end{document}

Pretty nailed it.
Is the solution with\begin{textblock*}a good one at all for positioning the graphics?

You can instruct \includegraphics on which overlays your image should be displayed, e.g. if you want it to act like of there had been a \pause before the image, use <+(1)->.

And as you have already been told in comments, you don't need graphicx in beamer.

\documentclass[10pt]{beamer}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}
\usepackage{lmodern}
\usepackage{ngerman}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{textcomp}
\usepackage{lipsum}
\usepackage{gensymb}
\usepackage[absolute,overlay]{textpos}
%\usepackage{graphicx}

\begin{document}
\begin{frame}
    \frametitle{Try 1}
    \begin{textblock*}{\textwidth}(0.8\textwidth,1cm)%specific position, I hope the numbers cannot matter...
        \includegraphics<+(1)->[width=4cm,keepaspectratio]{example-image}
    \end{textblock*}\vfill\pause
\lipsum[1]
\pause
\lipsum[2]
\end{frame}
\end{document}

[Tex/LaTex] Beamer \pause with TikZ

The easiest way to do this that I have found is to provide overlay specifications to the elements of the picture. The basic commands, \path, \draw, \node and so forth are all overlay-aware. The one thing to be ware of is that the bounding box might jump around a bit as different parts of the drawing are put in or taken out. However, once you're aware of that then it's easy to fix. Either specify the bounding box at the start (using the \useasboundingbox) or litter your drawing with lots of \coordinates which are there all the time but only use them on specific slides.

Here's a fairly detailed example with the \useasboundingbox technique.

\documentclass{beamer}
\usepackage{tikz}

\begin{document}
\begin{frame}
\begin{center}
\begin{tikzpicture}
\useasboundingbox (-5.2,-3.1) rectangle (5.2,3.1);
\fill[gray!25] (-5.2,-3.1) rectangle (-0.2,3.1);
\draw[ultra thick,red] (-5,0) -- (-0.4,0);
\draw[ultra thick] (-2.7,-3) -- (-2.7,3);
\foreach \t in {-1.5,-1.4,...,1.5} {
\pgfmathsetmacro{\l}{abs(\t/1.5)}
\pgfmathsetmacro{\m}{1 - \l}
\definecolor{currentcolor}{rgb}{\l,0,\m}
\draw[color=currentcolor] (-5,\t) -- (-0.4,\t);
};
\foreach \t in {1.6,1.7,...,3} {
\pgfmathsetmacro{\l}{2-abs(\t/1.5)}
\pgfmathsetmacro{\m}{1 - \l}
\definecolor{currentcolor}{rgb}{\l,0,\m}
\draw<.(4)->[color=currentcolor] (-5,\t) -- (-0.4,\t);
\draw<.(4)->[color=currentcolor] (-5,-\t) -- (-0.4,-\t);
};
\fill<.(2)->[gray!25] (5.2,-3.1) rectangle (0.2,3.1);
\draw<.(2)->[ultra thick,red] (5,0) -- (0.4,0);
\draw<.(2)->[ultra thick] (2.7,-3) -- (2.7,3);
\foreach \t in {-2,-1.9,...,2} {
\pgfmathsetmacro{\l}{abs(\t/2)}
\pgfmathsetmacro{\m}{1 - \l}
\pgfmathsetmacro{\x}{2.3*cos(90*\t)};
\pgfmathsetmacro{\y}{2.3*sin(90*\t)};
\definecolor{currentcolor}{rgb}{\l,0,\m}
\draw<.(3)->[color=currentcolor] (2.7,0) -- +(\x,\y);
};

\end{tikzpicture}

\visible<2->{\(z \mapsto e^{z}\)}
\end{center}

\end{frame}
\end{document}

First frame:

first frame of exponential

Last frame:

last frame of exponential

[Tex/LaTex] In beamer, how to use \pause inside \only

I don't have my LaTeX here, but this ought to work. You have to rewrite each \pause to proper <n-m> syntax.

\begin{frame}
\frametitle{An example}
\only<1>{
insert a picture for instance
}
\only<2-3>{
\begin{itemize}
\item<2-3> here is my first remark
\item<3-3> and here is my second
\end{itemize}
}
\only<4>{
insert a 2nd picture
}
\only<5-6>{
\begin{itemize}
\item<5-6> bla bla bla
\item<6-6> ...
\end{itemize}
}
\end{frame}
