如何在pdf中添加自己小工具，以下示范添加一个打圈圈功能的插件

新建文本文档.txt

把下面代码复制粘贴到文件中保存并改名qq.js

插件放在安装目录下

设置一下

工具就出现

global.cs = 1; //count 开始号码

global.cs1 = 8; //字体大小

global.cs2 = 10; //圈圈大小

var dialog1 =

{

initialize: function(dialog){

}

, commit: function(dialog)

{

// called when OK pressed

var results = dialog.store();

global.cs = results["fnum"];

global.cs1 = results["tnum"];

global.cs2 = results["qnum"];

}
