MathML转换成图片步骤

MathML转换成图片方法
1. MathML介绍

MathML是什么就不解释了，请参考：

1. IBM：https://www.ibm.com/developerworks/cn/xml/x-mathml3/

2.Wiki百科：http://zh.wikipedia.org/zh/%E6%95%B0%E5%AD%A6%E7%BD%AE%E6%A0%87%E8%AF%AD%E8%A8%80

最近在翻译《High Performance Browser Networking》时，里面有很多的公式采用的是MathML编辑的，但是CSDN这个编辑器不支持MathML，因此复杂的公式无法在博客中展现，研究了一下，发现有一个开源工具jeuclid可以支持将mathML公式转换成各种格式的图片，且支持多种配置，使用起来比较方便。

比如下面这个公式（因为CSDN不支持MathML，只好采用截图）

其对应的MathML描述应该是：

将上面的MathML保存成一个XML文件（文件后缀名其实可以任意），执行脚本
mml2xxx.bat 1.xml 1.png -fontSize 36.0 -backgroundColor gray
可以得到如下图片

效果还不错，更多的效果，等待你自己去发现。
