需求如题，现在首先明白，最新版本的emacs自带了muse-latex2png.el文件。该程序会将latex转换成png，然后显示在html图片上。

在~/.emacs中添加：

(require 'muse-latex2png)

apt-get install dvipng

好了，打开Muse文档，输入如下标记：

<latex>
\[
E = mc^2
\]
</latex>

会显示：

觉得生成的公式图片太大了？可以在~/.emacs中设置变量muse-latex2png-scale-factor的值。

(custom-set-variables
  ;; custom-set-variables was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.

 '(muse-latex2png-scale-factor 1.2))
(custom-set-faces
  ;; custom-set-faces was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.

参考这篇文章，有一些选项设置可借鉴。
