Photoshop script for verifying layer names

Question

Photoshop script for verifying layer names

I am currently working on a script to verify my images. Here are the criteria I need to validate:

Determine the number of layers and pathItems in the document - relatively straightforward.
Identifying the names of 3 specific layers: I have hit a roadblock here
Ensuring that these 3 layers are of type NORMAL - not smart objects or solid colors...

#target photoshop  

var doc = app.activeDocument;
var pLen = doc.pathItems.length;
var pArray = [];
var nLen = doc.layers.length;
var cArray = [];

if (nLen != 3) 
{alert ("Incorrect structure")}
else if (pLen != 2 )
{alert ("Incorrect path item")}
else {for (var i=0; i<nLen; i++)
{if (doc.layer[i].getByName ("Freisteller") == false || doc.layer[i].getByName ("Hintergrund") == false || doc.layer[i].getByName ("Hintergrund BR") == false )
{alert ("Invalid layer name")}
}
}

I have attempted another solution but it is not functioning as expected

#target photoshop  

var doc = app.activeDocument;
var pLen = doc.pathItems.length;
var pArray = [];
var nLen = doc.layers.length;
var cArray = [];
var layerName = ["Freisteller", "Hintergrund", "Hintergrund BR"];
 
if (nLen != 3) 
{alert ("Incorrect structure")}
else if (pLen != 2)
{alert ("Incorrect path item")}
else {for (var i=0; i<nLen; i++)
{if (doc.layer[i].getByName ("Freisteller") != layerName || doc.layer[i].getByName ("Hintergrund") != layerName || doc.layer[i].getByName ("Hintergrund BR") != layerName )
{alert ("Invalid layer name")}
}
}

Your assistance in resolving this issue would be greatly appreciated

Answer №1

To identify different types of layers in Photoshop, you can use the following conditions: typename == "ArtLayer" for normal art layers,

layer.kind == "LayerKind.SMARTOBJECT"

for smart objects, and layer.isBackgroundLayer == true for background layers.

If your script is not working as expected, it may be due to using the incorrect method like getbyname.

doc.activeLayer = doc.artLayers.getByName("Freisteller");

This code snippet will select the layer named "Freisteller", or the first layer if there are multiple layers with that name. Instead of trying to obtain it from the layer index directly.

I have made some modifications to your script:

#target photoshop  

var doc = app.activeDocument;
var pLen = doc.pathItems.length;
var nLen = doc.layers.length;
var layerName = ["Freisteller", "Hintergrund", " Hintergrund BR"];

if (nLen != 3) 
{
  alert ("Incorrect structure\n" + nLen + " layers found in file.");
}
else if (pLen != 2)
{
  alert ("Incorrect path item count");
}
else 
{
  for (var i = nLen -1; i >= 0; i--)
  {
    var n = doc.layers[i].name;
    if (n == "Freisteller" || n == "Hintergrund" || n == "Hintergrund BR") 
    {
      // All good
    }
    else alert ("Wrong layer name");
  }
}

Additionally, here's a function that might assist you further:

// call the source document
var srcDoc = app.activeDocument;
var numOfLayers = srcDoc.layers.length;

// main loop
for (var i = numOfLayers -1; i >= 0; i--)
{
    var thisLayer = srcDoc.layers[i];
    srcDoc.activeLayer = thisLayer;
    var k = what_type(thisLayer);
    alert(thisLayer.name  + "\nis a " + k);
}


function what_type(alayer)
{
  if (alayer.isBackgroundLayer == true) return "background layer";
  var lk = alayer.kind;
  if (lk == "LayerKind.SMARTOBJECT") return "smart object";
  else if (lk == "LayerKind.TEXT") return "text layer";
  if (alayer.typename == "ArtLayer") return "normal art layer";
  else return undefined;
}
