Utilize Photoshop's Javascript feature to extract every layer within the currently active document

Question

Utilize Photoshop's Javascript feature to extract every layer within the currently active document

Looking for insights on a Photoshop scripting issue. I have written a solution but it's not producing the correct result. Can anyone provide feedback on what might be wrong with the code? The goal is to retrieve all the layers in a document.

Here is the code:

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;  
}

Appreciate any help or discussion on this topic.

Answer №1

Although this discussion is from a while back, I wanted to share some helpful information.

I recently needed a function to retrieve all ArtLayers within a Photoshop composition, even those located within groups. The original function provided was returning undefined for me, so I made some modifications and managed to get it working properly.

var document = app.activeDocument;
var layersArray = [];
var layersArray = getAllLayers(document, layersArray);

function getAllLayers(doc, array){
    for (var i = 0; i < doc.layers.length; i++){
        var currentLayer = doc.layers[i];
        if (currentLayer.typename === "ArtLayer"){
            array.push(currentLayer);
        }else{
            getAllLayers(currentLayer, array);
        }
    }
    return array;
}

Expanding on Ghoul Fool's original post, this script specifically targets only the visible art layers in the active document. :P

// Retrieve all visible layers in the active document
var sourceDocument = app.activeDocument;
var visibleLayers  = [];
var visibleLayers  = collectAllVisibleLayers(sourceDocument, visibleLayers);

// Display total number of visible layers found
alert(visibleLayers.length);


// Function to recursively gather all visible art layers in a given document
function collectAllVisibleLayers(parent, allVisibleLayers)
{
    for (var m = 0; m < parent.layers.length; m++)
    {
        var currentLayer = parent.layers[m];
        if (currentLayer.typename === "ArtLayer")
        {
            if(currentLayer.visible)
            {
                allVisibleLayers.push(currentLayer);
            }
        }
        else
        {
            collectAllVisibleLayers(currentLayer, allVisibleLayers);
        }
    }
    return allVisibleLayers;
}

In order to access all the layers, including sub layers, a recursive function is required.

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


function collectAllLayers (parentLayer, level)
{
  for (var i = parentLayer.layers.length - 1; i >= 0; i--)
  {
    var currentLayer = parentLayer.layers[i];
    if (currentLayer.typename != "ArtLayer")
    {
      layerCollection.push(level + currentLayer.name);
      collectAllLayers(currentLayer, level + 1)
    }
  }
}
