Apply layer color id based on name

[saikirans54625543]

Hi, can experts here help me with a script that applies layer color id to red if the layer name has exposure, level and layer?

Finally, a script that removes all the layer color id if there are no more layer names that have exposure, level and layer

Hi Saikiran,

Hope this will helps...

if(documents.length>0) main();  
function  main(){  
    var docRef = app.activeDocument;    
    var myLayers=docRef.layers;
    for(i=0;i<myLayers.length;i++){
        if(myLayers.name.indexOf("Layer")!=-1 || myLayers.name.indexOf("Exposure")!=-1 || myLayers.name.indexOf("Levels")!=-1){ 
            docRef.activeLayer=myLayers;
            colorLayer (i, "red"); 
        }
        else{
            docRef.activeLayer=myLayers;
            colorLayer (i, "none"); 
        }
    }
}
function colorLayer (layerIndex, color){    
    var desc1 = new ActionDescriptor();    
    var ref1 = new ActionReference();    
    ref1.putIndex (stringIDToTypeID ("layer"), layerIndex);    
    desc1.putReference (stringIDToTypeID ("target"), ref1);    
    var desc2 = new ActionDescriptor();    
    desc2.putEnumerated (stringIDToTypeID ("color"), stringIDToTypeID ("color"), stringIDToTypeID (color));    
    desc1.putObject (stringIDToTypeID ("to"), stringIDToTypeID ("layer"), desc2);  
    executeAction (stringIDToTypeID ("set"), desc1, DialogModes.NO);  
}

Hi natrev,

Thank you so much for the script.It's working when I open a new document and apply the scripts.But I am getting this error if I open an existing comp and add exposure adjustment or put those layers in a group.Also, it's turning on all layers at the end of the script.

Hi

Could post Layer structure screen shot?

or Try this... code

if(documents.length>0) main();  
function  main(){  
    var docRef = app.activeDocument;    
    var myLayers=docRef.layers;
    for(i=0;i<myLayers.length;i++){
        var layVisible=myLayers.visible;
        docRef.activeLayer=myLayers;
        if(myLayers.name.indexOf("Layer")!=-1 || myLayers.name.indexOf("Exposure")!=-1 || myLayers.name.indexOf("Levels")!=-1){ colorLayer (i, "red"); }
        else { colorLayer (i, "none"); }
        myLayers.visible=layVisible;
    }
}
function colorLayer (layerIndex, color){    
    var desc1 = new ActionDescriptor();    
    var ref1 = new ActionReference();    
    ref1.putIndex (stringIDToTypeID ("layer"), layerIndex);    
    desc1.putReference (stringIDToTypeID ("target"), ref1);    
    var desc2 = new ActionDescriptor();    
    desc2.putEnumerated (stringIDToTypeID ("color"), stringIDToTypeID ("color"), stringIDToTypeID (color));    
    desc1.putObject (stringIDToTypeID ("to"), stringIDToTypeID ("layer"), desc2);  
    executeAction (stringIDToTypeID ("set"), desc1, DialogModes.NO);  
}

Sure, if I have them in a group like this it's not working.BTW group name will change depending on the project

layer "test" turning on when I run the script.

Here is a basic structure and I added level and exposure to the file and I saved it out and then I opened it and ran the script and got the error

Once again thank you for helping me

Amazing!!! Thank you so much.This works perfectly.One more request, please.I would like to run the other script that removes red id but gives an error if one of the layer has exposure, layer or level to it.

[Davide_Barranca]

So you'd like to have two scripts, one that applies red to those layers, and another which resets red, do I get it right?

Davide

[saikirans54625543]

Yes you are correct!

Hi Davide,

The reset is removing the id color in the file even if it has exposure and layer to it.Is it possible to remain the color as it is to those layers that have those names until they are changed?

[Davide_Barranca]

I did get that this was the intended behavior: one script sets the Red for Layers, Levels and Exposure strings, the other script reverts the Red (i.e. removes the Red to those layers and brings them to no color). If that's not the case, I'm not getting what the second script should do – let me know! 🙂

[saikirans54625543]

Sorry, it still has exposure and level to it but named differently like may be.shirt exp and sleeve level.If they are still named as exposure and level then the id color remains the same

[Davide_Barranca]

So basically you'd like to have a  script that sets Red for whatever contains those "layers" "levels" and "exposure" strings, and at the same times resets the color to None to those layers that don't contain the strings, right? No need to split this in two scripts...

Did I get it?

[saikirans54625543]

I think the first script actually does that.I still would like to have the reset as the other script as I want to change the name of my layers and run the script just in case if I missed any layers that I need to rename.

Something like this

[Davide_Barranca]

We're getting there... 🙂

So the first script *just* sets the Red:

#target photoshop
app.bringToFront();
app.activeDocument.suspendHistory('Setting Red colortag', 'main()');
function main(){
if(!documents.length) return;
selectAllLayers();
var selLayers = getSelectedLayersIdx();
for(var a in selLayers){
        colorLayer(Number(selLayers));
    }
}
function colorLayer(idx){
    var ref = new ActionReference();
    ref.putProperty( charIDToTypeID("Prpr") , stringIDToTypeID( "name" ));
    ref.putIndex( charIDToTypeID( "Lyr " ), idx);
    var desc = executeActionGet(ref);
    makeActiveByIndex( idx );
    var layerName = desc.getString(stringIDToTypeID('name'));
    if(layerName.indexOf("Layer")!=-1 || layerName.indexOf("Exposure")!=-1 || layerName.indexOf("Levels")!=-1){
        var desc1 = new ActionDescriptor();      
        var ref1 = new ActionReference();      
        ref1.putIndex (stringIDToTypeID ("layer"), idx);      
        desc1.putReference (stringIDToTypeID ("target"), ref1);      
        var desc2 = new ActionDescriptor();      
        desc2.putEnumerated (stringIDToTypeID ("color"), stringIDToTypeID ("color"), stringIDToTypeID ("red"));      
        desc1.putObject (stringIDToTypeID ("to"), stringIDToTypeID ("layer"), desc2);    
        executeAction (stringIDToTypeID ("set"), desc1, DialogModes.NO); 
    }
}
function makeActiveByIndex( idx ){
    var desc = new ActionDescriptor();
      var ref = new ActionReference();
      ref.putIndex(charIDToTypeID( "Lyr " ), idx)
      desc.putReference( charIDToTypeID( "null" ), ref );

   executeAction( charIDToTypeID( "slct" ), desc, DialogModes.NO );
};

        var ref23 = new ActionReference();
        ref23.putEnumerated( charIDToTypeID('Lyr '), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
    desc29.putReference( charIDToTypeID('null'), ref23 );
    executeAction( stringIDToTypeID('selectAllLayers'), desc29, DialogModes.NO );
};
function getSelectedLayersIdx(){
  var selectedLayers = new Array;
  var ref = new ActionReference();
  ref.putEnumerated( charIDToTypeID("Dcmn"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );
  var desc = executeActionGet(ref);
  if( desc.hasKey( stringIDToTypeID( 'targetLayers' ) ) ){
  desc = desc.getList( stringIDToTypeID( 'targetLayers' ));
  var c = desc.count
  var selectedLayers = new Array();
  for(var i=0;i<c;i++){
  try{
  activeDocument.backgroundLayer;
  selectedLayers.push(  desc.getReference( i ).getIndex() );
  }catch(e){
  selectedLayers.push(  desc.getReference( i ).getIndex()+1 );
  }
  }
  }else{
  var ref = new ActionReference();
  ref.putProperty( charIDToTypeID("Prpr") , charIDToTypeID( "ItmI" ));
  ref.putEnumerated( charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );
  try{
  activeDocument.backgroundLayer;
  selectedLayers.push( executeActionGet(ref).getInteger(charIDToTypeID( "ItmI" ))-1);
  }catch(e){

The second script sets the red to those layers, and in case also removes the red from the layers where the strings are missing:

We are almost there Looks like it's working and keeping the layer red if they are not in a group but it's removing the red color if the layer is in a group.

Here is how it looks, level in group is not red

Second script sets the red to those layers, and in case also removes the red from the layers where the strings are missing:
