用于创建和应用图层蒙版的 Photoshop JS 脚本

我用 JS 编写了一个 Photoshop 脚本，它采用每个图层文件夹并将其像精灵表一样分隔开。我已经弄清楚了这一部分，但我正在尝试在运行脚本时消除任何形式的人为错误。现在，您需要使用每个图层文件夹的正确命名来准备文件，并且还必须对选区应用图层蒙版。

我想消除用户应用图层蒙版的需要。我可以选择图层，然后选择我想要遮罩的部分，但我不知道如何应用或创建遮罩。

我希望它应用到的地方：

function maskIt(){
    if(currentFrameCount < (frameNumber-1)){
        currentFrameCount = currentFrameCount+1;
        currentFrame = ("frame"+currentFrameCount);
        activeDocument.layers[currentFrame].visable;
        activeDocument.selection.selectAll();
        //createMask();
        maskComplete = false;
    } else  if (currentFrameCount == (frameNumber-1)){
        currentFrameCount = currentFrameCount+1;
        currentFrame = ("frame"+currentFrameCount);
        activeDocument.layers[currentFrame].visable;
        activeDocument.selection.selectAll();
        //createMask();
        currentFrameCount = 0;
        maskComplete = true;
    }
}

这是一个更干净的版本try添加以检查掩码是否存在。如果您想应用任何蒙版，只需移动该线即可deleteLayerMask(true); below catch (e) {}

addMasks();

function addMasks(){

    try{
        loadLayerSelection();
        addLayerMask();
        deleteLayerMask(true);
        } catch (e) {}
};

// =======================================================
function loadLayerSelection() {
    var c2t = function (s) {
        return app.charIDToTypeID(s);
    };

    var s2t = function (s) {
        return app.stringIDToTypeID(s);
    };

    var descriptor = new ActionDescriptor();
    var reference = new ActionReference();
    var reference2 = new ActionReference();

    reference.putProperty( s2t( "channel" ), s2t( "selection" ));
    descriptor.putReference( c2t( "null" ), reference );
    reference2.putEnumerated( s2t( "channel" ), s2t( "channel" ), s2t( "transparencyEnum" ));
    descriptor.putReference( s2t( "to" ), reference2 );
    executeAction( s2t( "set" ), descriptor, DialogModes.NO );
}

// =======================================================
function addLayerMask() {
    var c2t = function (s) {
        return app.charIDToTypeID(s);
    };

    var s2t = function (s) {
        return app.stringIDToTypeID(s);
    };

    var descriptor = new ActionDescriptor();
    var reference = new ActionReference();

    descriptor.putClass( s2t( "new" ), s2t( "channel" ));
    reference.putEnumerated( s2t( "channel" ), s2t( "channel" ), s2t( "mask" ));
    descriptor.putReference( s2t( "at" ), reference );
    descriptor.putEnumerated( s2t( "using" ), c2t( "UsrM" ), s2t( "revealSelection" ));
    executeAction( s2t( "make" ), descriptor, DialogModes.NO );
}

// =======================================================
function deleteLayerMask(apply) {
