XeLaTeX: how do I make paper to be exactly the size of the content?

Question

In LaTeX I can make a document to be exactly the size of the content:

\documentclass{article}
\usepackage[active]{preview}
\begin{document}
\begin{preview}
  \[
  \pi = \sqrt{12}\sum^\infty_{k=0} \frac{(-3)^{-k}}{2k+1}
  \]
\end{preview}
\end{document}

And compile that with

latex foo.tex
dvipng -T tight -D 231.26 -o foo.png foo.dvi

it makes an image exactly the size of the content (formula).

How do I get the same with XeLaTeX?

I need that because I use inkscape export to latex for images -- and sometimes I need the images as standalone files, not inside a tex document.

Edit:

Here's a full MWE:

\documentclass{article}
\usepackage{todonotes}

\begin{document}

\missingfigure[figwidth=6cm]{}

\end{document}

I actually use

\begin{figure}
  \centering
  \def\svgwidth{1\columnwidth}
  \input{2dSqFermi_2el.pdf_tex}
\end{figure}

as a figure (that's what "inkscape export to latex" is about) -- but that's not important. So in the initial MWE I've just used formula. I see that the given answers already solve that.

Question is not understandable. – kiss my armpit Mar 26 '13 at 05:40 — kiss my armpit, Mar 26 '13 at 05:40

Method 1 (Using standalone document class)

enter image description here

\documentclass[preview]{standalone}
\begin{document}
$
  \displaystyle
  \pi = \sqrt{12}\sum^\infty_{k=0} \frac{(-3)^{-k}}{2k+1}
$
\end{document}

Method 2 (Using geometry package)

enter image description here

\documentclass{article}
\usepackage{graphicx}
\newsavebox\IBox
\savebox\IBox{\raisebox{\depth}{$\displaystyle\pi = \sqrt{12}\sum^\infty_{k=0} \frac{(-3)^{-k}}{2k+1}$}}
\usepackage[paperwidth=\wd\IBox,paperheight=\ht\IBox,margin=0pt]{geometry}

\begin{document}
\noindent\usebox\IBox
\end{document}

Another posibility is to use the magnífic Latexit program. – jpayansomet Mar 26 '13 at 06:14

I end up using Your standalone approach. – Adobe Mar 26 '13 at 06:30

Take the look into the standalone package.

Example:

\documentclass[varwidth]{standalone}
\begin{document}
  \[
  \pi = \sqrt{12}\sum^\infty_{k=0} \frac{(-3)^{-k}}{2k+1}
  \]
\end{document}

Result:

Yours solution works too sir. It's sad I can't accept multiple answers. – Adobe Mar 26 '13 at 06:30
