Uncovering figures

[kmalysiak]

Hi everyone!

I am somehow newbie into the Beamer, so maybe the question is naive, but...
I've tried to google quite hard, looked up previous posts and got through the Manual...
Is there any environment for figures that would be overlay-specification aware?
I just want to get the following: on the first overlay text + reserved place for a figure
on the next overlay: text + visible figure.

I've tried to work with commands like \onslide, \pause, etc. but none of the worked...

Thanks for any help,
Chris

Dear Chris,

Welcome to beamer.  I think you can get what you want like this:

\begin{frame}
Text goes here

\uncover<2>{\includegraphics{figure} % figure goes here}
\end{frame}

You can put anything inside the uncover argument.  But \pause in  
place of the \uncover<2>{...} should work the same way, too.

Hope that helps!

To my experience with:

  \setbeamercovered{transparent}


uncover on figures does not work because uncovers working mechanisms
seems to change text color. That *might* work on some (eps) images
which are not setting color internally. But png/jpg will not "cover".

If you want the transparency,

You can use \only<1>{\includegraphics[]{...}}

that will not reserve the space and you would have to improvise with
sabe boxes.


or you can set

  \setbeamercovered{invisible}

just around the frame with the image. Then uncover works on all image
types.

Matthew and Karl-Heinz have given you a few alternatives. I'll add one more:

------

\documentclass{beamer}
\begin{document}

\begin{frame}
This is some text visible on all frames.
\begin{figure}
% Load figure on frame one but don't show it. Just reserve the space
\phantom{\includegraphics<1>{testimg}}
% From frame 2 show the figure
\includegraphics<2->{testimg}
\end{figure}
Some more text.

\end{frame}
\end{document}

----

The above code will first load the figure inside a \phantom. This
command creates an empty box with the same size as its content. Very
useful when you want to reserve some space. From the next frame we can
show the figure as normal. I'm not sure how smart the \includegraphics
command. It may be that the image is loaded twice. If this is a
problem there are workarounds.

You can write the above pattern in a macro if you want:

-------

\documentclass{beamer}
\begin{document}

% Include a graphics, reserve space for it but
% show it on the next frame.
% Parameters:
% #1 Options to \includegraphics (optional)
% #2 Name of graphic
\newcommand{\reserveandshow}[2][]{%
    \phantom{\includegraphics<+>[#1]{#2}}%
    \includegraphics<+->[#1]{#2}%
}

\begin{frame}
This is some text visible on all frames.
\begin{figure}
\reserveandshow[width=6cm]{testimg}
\end{figure}
Some more text.

\end{frame}
\end{document}

--------

Hope this helps.

Dear all,

yet another alternative (which works also in conjunction with \setbeamercovered{transparent}):


  \onslide<1-2>{
      Text shown on slides 1-2.\\
  }
  \invisible<1>{
       % The figure only shown on slide 2:
         \begin{figure}
           ...
         \end{figure}
  }


This makes the figure invisible before slide 2, but reserves the space.
It is important to use \uncover<1-2> and not \uncover<1->, because this would not produce a second slide.

Hope that helps!
