Question

我在JS中编写了一个Photoshop脚本，它采用每个图层文件夹，并像精灵表一样将其空出。我已经找到了那个部分，但是我正在尝试在运行脚本时删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准备文件，并且还必须对选区应用图层蒙版。

我想删除用户应用图层蒙版的需要。我可以选择图层，然后选择我要屏蔽的部分，但我不知道如何应用或创建蒙版。

我想要应用的地方：

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;
    }
}

Answer 1

这两个从scriptlistener整理的功能可以帮助你：

// FUNCTION MAKE MASK ()
function makeMask()
{
  // =======================================================
  var id4556 = charIDToTypeID( "setd" );
  var desc983 = new ActionDescriptor();
  var id4557 = charIDToTypeID( "null" );
  var ref657 = new ActionReference();
  var id4558 = charIDToTypeID( "Chnl" );
  var id4559 = charIDToTypeID( "fsel" );
  ref657.putProperty( id4558, id4559 );
  desc983.putReference( id4557, ref657 );
  var id4560 = charIDToTypeID( "T   " );
  var ref658 = new ActionReference();
  var id4561 = charIDToTypeID( "Chnl" );
  var id4562 = charIDToTypeID( "Chnl" );
  var id4563 = charIDToTypeID( "Trsp" );
  ref658.putEnumerated( id4561, id4562, id4563 );
  desc983.putReference( id4560, ref658 );
  executeAction( id4556, desc983, DialogModes.NO );

  // =======================================================
  var id4564 = charIDToTypeID( "Mk  " );
  var desc984 = new ActionDescriptor();
  var id4565 = charIDToTypeID( "Nw  " );
  var id4566 = charIDToTypeID( "Chnl" );
  desc984.putClass( id4565, id4566 );
  var id4567 = charIDToTypeID( "At  " );
  var ref659 = new ActionReference();
  var id4568 = charIDToTypeID( "Chnl" );
  var id4569 = charIDToTypeID( "Chnl" );
  var id4570 = charIDToTypeID( "Msk " );
  ref659.putEnumerated( id4568, id4569, id4570 );
  desc984.putReference( id4567, ref659 );
  var id4571 = charIDToTypeID( "Usng" );
  var id4572 = charIDToTypeID( "UsrM" );
  var id4573 = charIDToTypeID( "RvlS" );
  desc984.putEnumerated( id4571, id4572, id4573 );
  executeAction( id4564, desc984, DialogModes.NO );
}


// FUNCTION APPLY LAYER MASK()
function applyLayerMask()
{
  // =======================================================
  var id1949 = charIDToTypeID( "Dlt " );
  var desc398 = new ActionDescriptor();
  var id1950 = charIDToTypeID( "null" );
  var ref291 = new ActionReference();
  var id1951 = charIDToTypeID( "Chnl" );
  var id1952 = charIDToTypeID( "Chnl" );
  var id1953 = charIDToTypeID( "Msk " );
  ref291.putEnumerated( id1951, id1952, id1953 );
  desc398.putReference( id1950, ref291 );
  var id1954 = charIDToTypeID( "Aply" );
  desc398.putBoolean( id1954, true );
  executeAction( id1949, desc398, DialogModes.NO );
}

如果你试图排除用户错误，你可能需要第三个功能来检测一个图层是否有遮罩（选择该图层，尝试复制并粘贴图层遮罩;如果不是粘贴 - 没有图层蒙版）

Answer 2

这是一个更干净的版本，其中添加了try，以检查是否存在掩码。如果要应用任何遮罩，只需将deleteLayerMask(true);下的行catch (e) {}移至

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

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

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

    reference.putEnumerated( s2t( "channel" ), s2t( "channel" ), s2t( "mask" ));
    descriptor.putReference( c2t( "null" ), reference );
    descriptor.putBoolean( s2t( "apply" ), apply );
    executeAction( s2t( "delete" ), descriptor, DialogModes.NO );
}

Answer 3

将蒙版（剪辑和/或图层）应用到当前选定对象的更简洁的方法：

// Clipping Mask
const applyClippingMask = function () {
    // Grab the needed IDs
    const groupEventID = stringIDToTypeID('groupEvent')
    const nullID = stringIDToTypeID('null')
    const layerID = stringIDToTypeID('layer')
    const ordinalID = stringIDToTypeID('ordinal')
    const targetEnumID = stringIDToTypeID('targetEnum')

    // Prep the action
    const actionDesc = new ActionDescriptor()
    const actionRef = new ActionReference()

    // Prep the mask
    actionRef.putEnumerated(layerID, ordinalID, targetEnumID)
    actionDesc.putReference(nullID, actionRef)
    
    // Apply the mask
    executeAction(groupEventID, actionDesc, DialogModes.NO)
}

// Layer mask from selection
const applyLayerMask = function () {
    // Required internal IDs
    const makeID = stringIDToTypeID('make')
    const newID = stringIDToTypeID('new')
    const channelID = stringIDToTypeID('channel')
    const atID = stringIDToTypeID('at')
    const usingID = stringIDToTypeID('using')
    const userMaskEnabledID = stringIDToTypeID('userMaskEnabled')
    const revealSelectionID = stringIDToTypeID('revealSelection')

    // Prep the action
    const actionDesc = new ActionDescriptor()
    const actionRef = new ActionReference()

    // Setup the mask
    actionDesc.putClass(newID, channelID)
    actionRef.putEnumerated(channelID, channelID, maskID)
    actionDesc.putReference(atID, actionRef)
    actionDesc.putEnumerated(usingID, userMaskEnabledID, revealSelectionID)

    // Apply the mask
    executeAction(makeID, actionDesc, DialogModes.NO)
}
