Photoshop Javascript来获取活动文档中的所有图层

Question

我确信它应该由Photoshop脚本编写人员讨论过。我写一个解决方案如下。我认为这在逻辑上是正确的，但结果是不正确的。任何人都可以帮助检查代码中的错误，或者对这个主题有想法？我想要获取文档中的所有图层。

代码：

function getAllLayersInLayerSets(layerNodes) { 

var retList = []; 

for (var i=0; i<layerNodes.length; i++) { 

    if(layerNodes[i].layerSets.length > 0) 
    { 
     var tmp = getAllLayersInLayerSets(layerNodes[i].layerSets); 

     var j = (tmp == null) ? -1 : tmp.length-1; 
     while(tmp && j>=0) 
     { 
      retList.push(tmp[i]); 
      j--; 
     } 
    } 
    for(var layerIndex=0; layerIndex < layerNodes[i].artLayers.length; layerIndex++) 
    { 
     var layer=layerNodes[i].artLayers[layerIndex]; 
     retList.push(layer); 
    } 

} 

return retList; 
} 

非常感谢任何帮助或讨论。

要获取所有层（以及子层），你必须有一个递归函数

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


function collectAllLayers (theParent, level) 
{ 
    for (var m = theParent.layers.length - 1; m >= 0; m--) 
    { 
    var theLayer = theParent.layers[m]; 
    if (theLayer.typename != "ArtLayer") 
    { 
     allLayers.push(level + theLayer.name); 
     collectAllLayers(theLayer, level + 1) 
    } 
    } 
}

我知道这是一个古老的线程，但是这可能是有用的人。

我正在寻找一个函数，它可以让我在Photoshop中的所有ArtLayers，包括嵌套在组中的图层。上面的函数返回undefined，所以我修改它并让它工作。

var doc = app.activeDocument; 
var allLayers = []; 
var allLayers = collectAllLayers(doc, allLayers); 

function collectAllLayers (doc, allLayers){ 
    for (var m = 0; m < doc.layers.length; m++){ 
     var theLayer = doc.layers[m]; 
     if (theLayer.typename === "ArtLayer"){ 
      allLayers.push(theLayer); 
     }else{ 
      collectAllLayers(theLayer, allLayers); 
     } 
    } 
    return allLayers; 
}

在Ghoul Fool的帖子上进行了一些小扩展，只在活动文档中获得所有可见的艺术图层。 ：P

// Get layers in a document 
var sourceDocument = app.activeDocument; 
var visibleLayers = []; 
var visibleLayers = collectAllLayers(sourceDocument, visibleLayers); 

// Print out total layers found 
alert(visibleLayers.length); 


// Recursively get all visible art layers in a given document 
function collectAllLayers (parent, allLayers) 
{ 
    for (var m = 0; m < parent.layers.length; m++) 
    { 
     var currentLayer = parent.layers[m]; 
     if (currentLayer.typename === "ArtLayer") 
     { 
      if(currentLayer.visible) 
      { 
       allLayers.push(currentLayer); 
      } 
     } 
     else 
     { 
      collectAllLayers(currentLayer, allLayers); 
     } 
    } 
    return allLayers; 
}
