AfterEffect(AE)插件是Adobe公司开发的特效制作软件，稳定快速的功能和特效，在视频制作领域使用非常广泛，本文向大家介绍如何在项目里进行命令行渲染功能。源代码如下所示：

// The constructor has 3 sections:
// [1] define all the variable-type attributes used by this class;
// [2] define all the functions used by this class;
// [3] assign all the functions to be method-type attributes.
