Question

我需要创建一个Photoshop脚本（我正在使用Java脚本），它会拍摄一些图像并对所有图像应用相同的蒙版。

（Here is what I mean by applying a mask）

使用此代码加载图像后

var sourceImageDoc = app.open(new File("./image.png"))
var maskImageDoc = app.open(new File("./mask.png"))

如何设置 maskImageDoc 作为 sourceImageDoc 的掩码？

以下是我的一个适用于CS3 +的脚本的一些片段。正如您所看到的，它使用丑陋的脚本侦听器代码 - 如果您将其应用于图层而不是组，您可能需要调整该部分？我不确定我是否记得曾经在图层而不是图层集上使用该功能。

//mask group to paper area 
app.activeDocument.activeLayer = lyr;   
selectRasterLayerContents();
app.activeDocument.activeLayer = grp;
AddMaskToGroup();   


//Selects the contents of the active layer.
function selectRasterLayerContents() {
var id47 = charIDToTypeID( "setd" );
    var desc11 = new ActionDescriptor();
    var id48 = charIDToTypeID( "null" );
        var ref11 = new ActionReference();
        var id49 = charIDToTypeID( "Chnl" );
        var id50 = charIDToTypeID( "fsel" );
        ref11.putProperty( id49, id50 );
    desc11.putReference( id48, ref11 );
    var id51 = charIDToTypeID( "T   " );
        var ref12 = new ActionReference();
        var id52 = charIDToTypeID( "Chnl" );
        var id53 = charIDToTypeID( "Chnl" );
        var id54 = charIDToTypeID( "Trsp" );
        ref12.putEnumerated( id52, id53, id54 );
    desc11.putReference( id51, ref12 );
executeAction( id47, desc11, DialogModes.NO );
}


//adds a mask revealing the selection to the active group
function AddMaskToGroup() {
    var id42 = charIDToTypeID( "Mk  " );
    var desc8 = new ActionDescriptor();
    var id43 = charIDToTypeID( "Nw  " );
    var id44 = charIDToTypeID( "Chnl" );
    desc8.putClass( id43, id44 );
    var id45 = charIDToTypeID( "At  " );
        var ref10 = new ActionReference();
        var id46 = charIDToTypeID( "Chnl" );
        var id47 = charIDToTypeID( "Chnl" );
        var id48 = charIDToTypeID( "Msk " );
        ref10.putEnumerated( id46, id47, id48 );
    desc8.putReference( id45, ref10 );
    var id49 = charIDToTypeID( "Usng" );
    var id50 = charIDToTypeID( "UsrM" );
    var id51 = charIDToTypeID( "RvlS" );
    desc8.putEnumerated( id49, id50, id51 );
executeAction( id42, desc8, DialogModes.NO );
}

应用图层蒙版很痛苦，因为脚本侦听器不会直接听到它。

你会想要这个

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 );
}

这是我的代码，用于将图层蒙版应用到当前选定的对象（前提是它有一个选择）。

const layerMask = function () {
    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')

    const actionDesc = new ActionDescriptor()
    const actionRef = new ActionReference()

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

    executeAction(makeID, actionDesc, DialogModes.NO)
}
