Photoshop Javascript To Get All Layers In The Active Document
I'm sure it should be discussed before by Photoshop scripters. I write a solution as following. I think it's logically right, but the result is not correct. Anybody can help to che
Solution 1:
I know this is an old thread, but this might be useful for someone.
I was looking for a function that would get me all the ArtLayers in a Photoshop comp, including layers nested in groups. The above function was returning undefined, so I modified it and got it to work.
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;
}
Solution 2:
To get all the layers (and sub layers) you have to have a recursive function
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)
}
}
}
Solution 3:
Minor expansion on Ghoul Fool's post to only get all VISIBLE art layers in the active document. :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;
}
Solution 4:
function selectAllLayers() {
var desc29 = new ActionDescriptor();
var ref23 = new ActionReference();
ref23.putEnumerated(charIDToTypeID('Lyr '), charIDToTypeID('Ordn'), charIDToTypeID('Trgt'));
desc29.putReference(charIDToTypeID('null'), ref23);
executeAction(stringIDToTypeID('selectAllLayers'), desc29, DialogModes.NO);
}
