Photoshop 脚本 - 获取 Group/Layerset 中可见图层的名称

Question

我被一个脚本困住了，该脚本检测在名称为 "Color".

的（子）层集（又名组）中哪个层是可见的

下面的脚本检查所有可见层并选择它们。我无法让它只在提到的图层集中做同样的事情。

非常感谢任何帮助！

#target photoshop
app.bringToFront();

main();
function main(){
if(!documents.length) return;
var Vis = getVisLayers();
deselectLayers();
for(var a in Vis){
    selectLayerById(Number(Vis[a]),true);
    }
}
function getVisLayers(){ 
   var ref = new ActionReference(); 
   ref.putEnumerated( charIDToTypeID('Dcmn'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') ); 
   var count = executeActionGet(ref).getInteger(charIDToTypeID('NmbL')) +1; 
   var Names=[];
try{
    activeDocument.backgroundLayer;
var i = 0; }catch(e){ var i = 1; };
   for(i;i<count;i++){ 
       if(i == 0) continue;
        ref = new ActionReference(); 
        ref.putIndex( charIDToTypeID( 'Lyr ' ), i );
        var desc = executeActionGet(ref);
        var layerName = desc.getString(charIDToTypeID( 'Nm  ' ));
        var Id = desc.getInteger(stringIDToTypeID( 'layerID' ));
        if(layerName.match(/^<\/Layer group/) ) continue;
        var layerType = typeIDToStringID(desc.getEnumerationValue( stringIDToTypeID( 'layerSection' )));
        var isLayerSet =( layerType == 'layerSectionContent') ? false:true;
        var vis = desc.getBoolean(charIDToTypeID( "Vsbl" ));
        if(!isLayerSet && vis) Names.push(Id);
   }; 
return Names;
};
function selectLayerById(ID, add) {
    add = (add == undefined)  ? add = false : add;
   var ref = new ActionReference();
   ref.putIdentifier(charIDToTypeID('Lyr '), ID);
   var desc = new ActionDescriptor();
   desc.putReference(charIDToTypeID('null'), ref);
   if (add) {
      desc.putEnumerated(stringIDToTypeID('selectionModifier'), stringIDToTypeID('selectionModifierType'), stringIDToTypeID('addToSelection'));
   }
   desc.putBoolean(charIDToTypeID('MkVs'), false);
   executeAction(charIDToTypeID('slct'), desc, DialogModes.NO);
}
function deselectLayers() { 
    var desc01 = new ActionDescriptor(); 
        var ref01 = new ActionReference(); 
        ref01.putEnumerated( charIDToTypeID('Lyr '), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') ); 
    desc01.putReference( charIDToTypeID('null'), ref01 ); 
    executeAction( stringIDToTypeID('selectNoLayers'), desc01, DialogModes.NO ); 
};

团体的麻烦在于你必须跳到最深处。遗憾的是，Photoshop 跟踪其图层的方式并不直观。最好的办法是使用递归函数并查看所有层 - 从中您将能够确定它是否是一个组。然后计算它是否可见。

var allLayers = new Array();
var theLayers = collectAllLayers(app.activeDocument, 0);

// function collect all layers
function collectAllLayers (theParent, level)
{
  for (var m = theParent.layers.length - 1; m >= 0; m--)
  {
    var theLayer = theParent.layers[m];

    if (theLayer.typename == "ArtLayer")
    {
      // find the art layers
      if (theLayer.visible == true)
      {
      //do stuff here
      }
    }
    else
    {
      allLayers.push(level + theLayer.name);
      collectAllLayers(theLayer, level + 1)
    }
  }
}

感谢@Ghoul Fool，我终于成功了。我稍微更改了代码，因为我只需要检查哪个图层可见并将此名称存储为变量。如果更熟练的人可以为将使用它或其中一部分的其他人更正我的代码，那就太好了。

再次感谢

// Checking which layer is visible in layeset (group) "Colors" in "Mockup.psd" aka mockupDoc and store it's name for later use in the "save" part.
var front = mockupDoc.layerSets.getByName("Front");
var colors = front.layerSets.getByName("Colors");
for (var m = colors.layers.length - 1; m >= 0; m--)
{
  var theLayer = colors.layers[m];
  if (theLayer.typename == "ArtLayer")
 {
    if (theLayer.visible == true)
    {
      // Sets a variable for the name of the visible Layer in the "Colors" Group, so i can use it later as a part of the Filename when saving.
      var activeColor = theLayer.name;
    }
  }
};
