====== Generate png images of equations ======

You can use the ''tex2png.sh'' to generate images of your equations. Add your
equation to a small tex file like ''equation.tex'' and run this command to generate
the ''png'' file (replacing ''equation'' with the name of your tex file excluding ''.tex''):

<code>
tex2png.sh equation
</code>

You may want to create and keep seperate tex files for each formula.
This works well if you are using eg. Google Docs for drafting your report
and then at the end you would like to switch to LaTeX for proper typesetting.
This way you don't have to key in the formulas twice.

''tex2png.sh''
<code>
#!/bin/bash
texi2dvi $1.tex
dvips -E $1.dvi
convert -density 110x110 $1.ps $1.png
rm $1.ps $1.dvi $1.aux $1.log
</code>

''equation.tex''
<code>
\documentclass{article}
\pagestyle{empty}
\begin{document}

$\mathbf{c^2} = \mathbf{a^2} + \mathbf{b^2}$

\end{document}
</code>
