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晕影白色相关功能，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
大家可通过源代码阅读，来掌握相关技巧，源代码如下：
if (app) { try { MainCatch3(); } catch (e) { }}function MainCatch3() { var getName = app.activeDocument.activeLayer.name; var idslct = charIDToTypeID("slct"); var desc410 = new ActionDescriptor(); var idnull = charIDToTypeID("null"); var ref300 = new ActionReference(); var idLyr = charIDToTypeID("Lyr "); ref300.putName(idLyr, "White_Vignetting"); desc410.putReference(idnull, ref300); var idMkVs = charIDToTypeID("MkVs"); desc410.putBoolean(idMkVs, false); var idLyrI = charIDToTypeID("LyrI"); var list239 = new ActionList(); list239.putInteger(94); desc410.putList(idLyrI, list239); executeAction(idslct, desc410, DialogModes.NO); var idsetd = charIDToTypeID("setd"); var desc422 = new ActionDescriptor(); var idnull = charIDToTypeID("null"); var ref309 = new ActionReference(); var idLyr = charIDToTypeID("Lyr "); var idOrdn = charIDToTypeID("Ordn"); var idTrgt = charIDToTypeID("Trgt"); ref309.putEnumerated(idLyr, idOrdn, idTrgt); desc422.putReference(idnull, ref309); var idT = charIDToTypeID("T "); var desc423 = new ActionDescriptor(); var idNm = charIDToTypeID("Nm "); desc423.putString(idNm, "White_Vignetting - old"); var idLyr = charIDToTypeID("Lyr "); desc422.putObject(idT, idLyr, desc423); executeAction(idsetd, desc422, DialogModes.NO); var idsetd = charIDToTypeID("setd"); var desc86 = new ActionDescriptor(); var idnull = charIDToTypeID("null"); var ref54 = new ActionReference(); var idLyr = charIDToTypeID("Lyr "); var idOrdn = charIDToTypeID("Ordn"); var idTrgt = charIDToTypeID("Trgt"); ref54.putEnumerated(idLyr, idOrdn, idTrgt); desc86.putReference(idnull, ref54); var idT = charIDToTypeID("T "); var desc87 = new ActionDescriptor(); var idClr = charIDToTypeID("Clr "); var idClr = charIDToTypeID("Clr "); var idNone = charIDToTypeID("None"); desc87.putEnumerated(idClr, idClr, idNone); var idLyr = charIDToTypeID("Lyr "); desc86.putObject(idT, idLyr, desc87); executeAction(idsetd, desc86, DialogModes.NO); var idslct = charIDToTypeID("slct"); var desc410 = new ActionDescriptor(); var idnull = charIDToTypeID("null"); var ref300 = new ActionReference(); var idLyr = charIDToTypeID("Lyr "); ref300.putName(idLyr, getName); desc410.putReference(idnull, ref300); var idMkVs = charIDToTypeID("MkVs"); desc410.putBoolean(idMkVs, false); var idLyrI = charIDToTypeID("LyrI"); var list239 = new ActionList(); list239.putInteger(94); desc410.putList(idLyrI, list239); executeAction(idslct, desc410, DialogModes.NO);}function White() { function step1(enabled, withDialog) { if (enabled != undefined && !enabled) { return; } var dialogMode = withDialog ?

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：
