Render Latex formula to image
Notice: This plugin is unmaintained and available for adoption.
20060420 update: This was originally created for a project which was using Trac 0.8. However, that project went away and so I haven't been using Trac. I haven't done anything with the latex hack since then, but other people have provided some patches for newer versions of Trac & other features. If someone wants to take over this page and continue development, please do.

Description
Render a latex formula to an image using Latex, dvips, and ImageMagick.
The images are named based on a sha1 hash of the formula and parameters, so that images don't have to be regenerated every time they are viewed.
In order to create the image from the formula text, the following is performed:
 create .tex file in temporary directory
 run latex on .tex file to produce .dvi file
 run dvips on .dvi file to produce .eps file
 run convert on .eps file to produce .jpg file
Requirements
 latex
 dvips
 convert (from the ImageMagic package)
 ghostscript

You can check out LatexFormulaMacro from here using Subversion, or browse the source with Trac.
Example
By default, the latex code is rendered in math mode. This allows for quick math expressions. There is also a builtin macro called "mat" which is used for formatting matricies, like this:
[[formula(\mat{R'\\G'\\B'} = \mathbf{A} \mat{R\\G\\B} + \mathbf{x})]]
For more complicated usage, use the {{{ ... }}} format and the "nomode" command to disable the displaymath mode:
{{{ #!formula #nomode A more complicated equation should be typeset in {\em displayed math\/} mode, like this: \[ z \left( 1 \ +\ \sqrt{\omega_{i+1} + \zeta \frac{x+1}{\Theta +1} y + 1} \ \right) \ \ \ =\ \ \ 1 \] }}}
