I have been trying to create a list and a bunch of subfigures (both on each half of the slide). I have used \setbeamercovered{transparent}
to progress along the list per keystroke. I want this keystroke to also be used to draw tikz overlays on the figure. I saw quite a few solutions, but all of them were using just a single figure. I cant seem to get it working for subfigures. Can someone please help me out..
Here is my minimal code..
\frame
{
\setbeamercovered{transparent}
\frametitle{Title}
\begin{minipage}[t]{0.5\linewidth}
\begin{itemize}[<+->]
\item
\item
\item
\item
\end{itemize}
\end{minipage}
\hfill
\vspace{-120pt}
\begin{minipage}[t]{2\linewidth}
\setcounter{subfigure}{0}
\begin{figure}[!th]
\centering
\subfigure[1]{
\includegraphics[scale=.25]{scen-q.pdf}
\label{fig:scen1subfig1}
}
\hspace{-10pt}
\subfigure[2]{
\includegraphics[scale=.25]{scen-b.pdf}
\label{fig:scen1subfig2}
}
\newline
\subfigure[3]{
\includegraphics[scale=.25]{scen-s.pdf}
\label{fig:scen1subfig3}
}
\subfigure[4]{
\includegraphics[scale=.25]{scen-sw.pdf}
\label{fig:scen1subfig4}
}
\hspace{130pt}
\label{fig:scencomp}
\end{figure}
\end{minipage}
}
I have seen this as a solution before
\begin{tikzpicture}
\node[anchor=south west,inner sep=0] at (0,0) {\includegraphics[width=1\textheight]{5.pdf}};
\draw<1>[red,ultra thick,rounded corners] (1.6,1) rectangle (\textheight-1cm,5);
\draw<2>[red,ultra thick,rounded corners] (5.7,4.1) rectangle (7.5,4.9);
\end{tikzpicture}
But how do I do the same for subfigures?
Best Answer
I am not sure if this is the kind of overlay effect that you are trying to achieve; I used
\onslide
so that each image will become visible simultaneously with a corresponding item:Please notice that I included some
%
characters that are essential to suppress spurious blank spaces. Also,subfigure
is an obsolete package, so it would be a good idea to usesubcaption
instead.Since I didn't have your actual figures, I used
\PassOptionsToPackage{demo}{graphicx}
; this simply replaces actual figures with black rectangles; delete that line in your actual document.
