1.AE定义内部结构
??开发AE插件会用到很多AE对内部数据结构的开发有一个大致的了解AE插件仍然很有帮助。源代码如下：
//CC #define PF_AE141_PLUG_IN_VERSION 13 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit is okay #define PF_AE141_PLUG_IN_SUBVERS 14 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit is okay #define PF_AE140_PLUG_IN_VERSION 13 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit is okay #define PF_AE140_PLUG_IN_SUBVERS 13 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit is okay #define PF_AE138_PLUG_IN_VERSION 13 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit is okay #define PF_AE138_PLUG_IN_SUBVERS 11 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit is okay // AE137 is same plugin version as AE136, below #define PF_AE136_PLUG_IN_VERSION 13 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit is okay #define PF_AE136_PLUG_IN_SUBVERS 10 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit is okay #define PF_AE135_PLUG_IN_VERSION 13 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit is okay #define PF_AE135_PLUG_IN_SUBVERS 9 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit is okay // AE131 and AE132 are the same plugin version as AE130, below #define PF_AE130_PLUG_IN_VERSION 13 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit okay #define PF_AE130_PLUG_IN_SUBVERS 7 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit okay #define PF_AE122_PLUG_IN_VERSION 13 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit okay #define PF_AE122_PLUG_IN_SUBVERS 6 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit okay #define PF_AE121_PLUG_IN_VERSION 13 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit okay #define PF_AE121_PLUG_IN_SUBVERS 5 // auto-set by prep_codeline_for_release.py, adjust comment if manually edit okay #define PF_AE120_PLUG_IN_VERSION 13 #define PF_AE120_PLUG_IN_SUBVERS 4 //CS6.0.1 //Plugins have to make dummy checkout (hack) to fix W3163764 in CS6.

PF_Quality_HI
};
typedef A_long PF_Quality;
enum {
PF_MF_Alpha_PREMUL = 0,
PF_MF_Alpha_STRAIGHT = (1L << 0)
};
typedef A_long PF_ModeFlags;

};
typedef A_long PF_ParamType;
有些参数阈值，有些是分哪些模块，它们都是可以转换成整形的有特定意义的标志。
