-This plugin renders LaTeX formulas into images.
+This plugin provides a [[ikiwiki/directive/teximg]] [[ikiwiki/directive]],
+that renders LaTeX formulas into images.
-Of course you will need LaTeX installed for this to work. The plugin
-also uses mhchem.sty, which in Debian is in the texlive-science package and
-may not be part of a regular texlive installation.

-## examples
+## configuration
- \[[teximg code="\ce{[Cu(NH3)3]^{2+}}"]]
- \[[teximg code="\frac{1}{2}"]]
- \[[teximg code="E = - \frac{Z^2 \cdot \mu \cdot e^4}{32\pi^2 \epsilon_0^2 \hbar^2 n^2}" ]]
-
-To scale the image, use height=x:
-
- \[[teximg code="\ce{[Cu(NH3)3]^{2+}}" height="17"]]
- \[[teximg code="\ce{[Cu(NH3)3]^{2+}}" height="8"]]
-
-If no height is choosen the default height 12 is used. Valid heights are: 8, 9,
-10, 11, 12, 14, 17, 20. If another height is entered, the closest available
-height is used.
-
-To add an alt text to the image, use alt="text":
-
- \[[teximg code="\frac{1}{2}" alt="1/2"]]
-
-See [this site](http://www.der-winnie.de/opensource/gsoc2007) for rendered images.
+There are several configuration directives that can be used in the setup
+file. `teximg_prefix` can be set to change the LaTeX preamble, and
+`teximg_postfix` to change the LaTeX postfix. The `teximg_dvipng` setting
+can be set to 0 to disable use of `dvipng`, and instead force use of `dvips`
+and `convert`.
