Apply Image with layer.id or layer.itemIndex

[Guest]

Hi,

I want to use the "Apply Image" function in my JavaScript.
Since this function is not available in the API, I recorded the function calls with the "ScriptListener.8li"
Here is the code, that has been generated (I reformated the code a bit to make it more readable):

function testIt() {
    var ref24 = new ActionReference();

    var idChnl = charIDToTypeID( "Chnl" );
    var idChnl = charIDToTypeID( "Chnl" );
    var idRGB = charIDToTypeID( "RGB " );
    ref24.putEnumerated( idChnl, idChnl, idRGB );

    var idLyr = charIDToTypeID( "Lyr " );
    ref24.putName( idLyr, "My Layer Name" );
        
    var desc30 = new ActionDescriptor();
    var idT = charIDToTypeID( "T   " );
    desc30.putReference( idT, ref24 );

    var idClcl = charIDToTypeID( "Clcl" );
    var idClcn = charIDToTypeID( "Clcn" );
    var idSbtr = charIDToTypeID( "Sbtr" );
    desc30.putEnumerated( idClcl, idClcn, idSbtr );

    var idScl = charIDToTypeID( "Scl " );
    desc30.putDouble( idScl, 2.000000 );

    var idOfst = charIDToTypeID( "Ofst" );
    desc30.putInteger( idOfst, 128 );

    var desc29 = new ActionDescriptor();
    var idWith = charIDToTypeID( "With" );
    var idClcl = charIDToTypeID( "Clcl" );
    desc29.putObject( idWith, idClcl, desc30 );

    var idAppI = charIDToTypeID( "AppI" );
    executeAction( idAppI, desc29, DialogModes.NO );
}

The Problem: The function is based on the layer name.
This can lead to problems if two layers have the same name:

ref24.putName( idLyr, "My Layer Name" );

How can I get this function work with "layer.id" or "layer.itemIndex"?
I tryed for more than 6 hours and haven't found a solution.
Please help!

Something on the lines of.

function apply(ID) {
var ref = new ActionReference();  
ref.putEnumerated( charIDToTypeID('Chnl'), charIDToTypeID('Chnl'), charIDToTypeID('RGB ') );  
ref.putIdentifier(charIDToTypeID('Lyr '), ID); //Layer ID
//ref.putIndex( charIDToTypeID('Lyr '), idx ); //Layer Index
var desc = new ActionDescriptor();  
desc.putReference( charIDToTypeID('T   '), ref );  
desc.putEnumerated( charIDToTypeID('Clcl'), charIDToTypeID('Clcn'), charIDToTypeID('Sbtr') );  
desc.putDouble( charIDToTypeID('Scl '), 2.000000 );  
desc.putInteger( charIDToTypeID('Ofst'), 128 );  
var desc2 = new ActionDescriptor();  
desc2.putObject( charIDToTypeID('With'), charIDToTypeID('Clcl'), desc ); 
try{
executeAction( charIDToTypeID('AppI'), desc2, DialogModes.NO );  
}catch(e){}
};
