[Tex/LaTex] Border or frame around figure

floatsframed

I'd like to place a border / frame around my figure.

The figure is a bunch of equations:

\begin{figure}[ht]
    \[ eqn 1 \]

    \[ eqn 2 \]

    \[ eqn 3 \]

    \caption{\label{myfig} My caption.}
\end{figure}

I've tried putting an \fbox{...} and \framebox[\textwidth]{...} around the equations but it doesn't work.

Preferably, I'd like the border to not include the caption.

Any hints are welcome…

With the package mdframed or framed this is possible

\documentclass{article}
\usepackage{mdframed}
\begin{document}
\begin{figure}[ht]
\begin{mdframed}
    \[ eqn 1 \]

    \[ eqn 2 \]

    \[ eqn 3 \]
\end{mdframed}
    \caption{\label{myfig} My caption.}
\end{figure}
\end{document}

The framed or mdframed packages allow you to put text in frames. Here's a way to do what you want with mdframed.

\documentclass{article}
\usepackage{caption}
\usepackage{listings}
\lstset{extendedchars=true,
    tabsize=3,
    frame=none,
    showspaces=false,
    boxpos=c,
    float=h,
    escapechar=\%
}
\usepackage[style=1]{mdframed}
\newcounter{boxctr}
\DeclareCaptionType{boxx}
\usepackage{needspace}
\newenvironment{Boxx}[2]{%
  \captionsetup{type=boxx}
  \begin{mdframed}[%
    linewidth=1pt,
    roundcorner=10pt,%
    leftmargin=.05\textwidth,
    rightmargin=.05\textwidth,
    skipabove=.7\baselineskip]%
    \refstepcounter{boxctr}%
    \label{#1}%
    \gdef\boxxcaption{\caption{#2}}
    \needspace{2\baselineskip}
  }{%
  \end{mdframed}%
  \boxxcaption%
}
\usepackage{lipsum}
\begin{document}
This is a reference to Box~\ref{box:one}!
\vspace{1.5cm}
\lipsum[1-4]
\begin{Boxx}{box:one}{This is a caption}
  \begin{enumerate}
  \item One
  \item Two
  \item Three
  \end{enumerate}
\end{Boxx}
\lipsum[1]
\begin{Boxx}{box:two}{This is also a caption}
  \begin{lstlisting}
    Also works with listings

    \foo is escaped!
  \end{lstlisting}
\end{Boxx}
\lipsum[2]
\end{document}

Boxes take two extra arguments: a label and a caption, just like the environment defined in the question. They use the caption package's captioning magic. So this should make doing lists of boxes easier. The label should stick with the bottom of the box now. This might lead to some ugly whitespace, but other than making the boxes float, this is probably as good as it gets.

[Tex/LaTex] Border around figure does not fit

There is no difference between a line of text made up of characters and a line that includes a graphic. TeX will consider it as just a single box; it will also consider all line endings as an extra space. You will have to use percentage characters as shown in the minimal below:

\documentclass{article}
\usepackage{graphicx,xcolor}
\begin{document}
\begin{figure}[htb]
\centering
\setlength\fboxsep{0pt}
\setlength{\fboxrule}{1pt}
\framebox{%
\color{red}
  \rule{35pt}{35pt}%
}
\end{figure}
\end{document}

I have used a rule to indicate the includegraphics. It is a good idea to always provide a minimal working example for other's to use to test their answers and a rule is convenient in this respect.
