  PS是一款栅格图像编辑软件，具有许多强大的功能，本文演示如何通过脚本实现蓝蒙板和添加图层蒙板相关功能，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：
在这里插入图片描述

2.关键代码

2.1 蓝蒙板

  大家可通过源代码阅读，来掌握相关技巧，源代码如下：

//
//==================== Blue Mask ==============
//
function BlueMask() {
    // Select
    function step1(enabled, withDialog) {
        if (enabled != undefined && !enabled)
            return;
        var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
        var desc1 = new ActionDescriptor();
        var ref1 = new ActionReference();
        ref1.putEnumerated(PSClass.Channel, PSClass.Channel, PSClass.Mask);
        desc1.putReference(PSString.Null, ref1);
        desc1.putBoolean(PSKey.MakeVisible, false);
        executeAction(PSEvent.Select, desc1, dialogMode);
    };

    // Apply Image
    function step2(enabled, withDialog) {
