PS是一款栅格图像编辑软件，模块众多。提供了脚本，动态连接库等多种扩展机制，本文演示如何通过脚本实现增加细节相关功能，展示从互联网收集而来的一个小插件，供大家学习交流，请勿用于商业用途。
1.插件界面本文界面是一系列功能的一部分，将逐步展示，但是功能界面是共同的，如下图所示：
大家可通过源代码阅读，来掌握相关技巧，源代码如下：

}3.代码转执行
使用记事本或者notepad 等文本编辑器，将代码拷贝至文本文件，然后修改后缀名为js或者jsx，最后再PS软件菜单文件》脚本》浏览，点执行即可，也可以将脚本放在预设文件夹内，会显示再脚本下的二级子菜单。如下图所示：
代码长度过长，如需全部项目或有疑问，请留言。
