用Emacs MUSE生成HTML报告时包含数学公式

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)但是依赖另一个程序转成png，在Ubuntu下安装：
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.
