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全尺寸锐化和网页锐化相关功能，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：

2.关键代码

2.1.全尺寸锐化

  大家可通过源代码阅读，来掌握相关技巧，源代码如下：

cTID = function (s) {
    return app.charIDToTypeID(s);
};
sTID = function (s) {
    return app.stringIDToTypeID(s);
};

//
//==================== High Pass Sharpen Full Size ==============
//
function HighPassSharpenFullSize() {
    // Layer Via Copy
    function step1(enabled, withDialog) {
        if (enabled != undefined && !enabled)
            return;
        var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
        executeAction(sTID('copyToLayer'), undefined, dialogMode);
    };

    // Set
    function step2(enabled, withDialog) {
        if (enabled != undefined && !enabled)

        var desc1 = new ActionDescriptor();
        desc1.putUnitDouble(cTID('Rds '), cTID('#Pxl'), 10);
        executeAction(sTID('highPass'), desc1, dialogMode);
    };

    HighPassForWebSharpen();

HighPassForWebSharpen.main();

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：
