Resize selected layers

  • February 2, 2022

welcome everybody
I have code that resizes a layer by a value
The code only works on one layer
I found a code that implements action on selected layers, but it doesn't work for me
It only works on one layer, and when implemented on more than one layer, it gives a very different result from what I want
I don't know where the problem is... and this is the code

 

    Width = 100
    Hight = 200
   
  //- Resize Layer With  Value - //
var startRulerUnits = app.preferences.rulerUnits;  
    app.preferences.rulerUnits = Units.PIXELS;  
    var bounds = activeDocument.activeLayer.bounds;  
    var width = bounds[2].value - bounds[0].value;
    var height = bounds[3].value - bounds[1].value;
    var newWidth = (100 / width) * Width;  
    var newHeight = (100 / height) * Hight;  
    
    
var layers = getSelectedLayers();
for (var i = 0; i < layers.length; i ++){
	layers[i].resize(newWidth, newHeight, AnchorPosition.MIDDLECENTER);
}    
    
function getSelectedLayers(){ 
	var idGrp = stringIDToTypeID( "groupLayersEvent" );
	var descGrp = new ActionDescriptor();
	var refGrp = new ActionReference();
	refGrp.putEnumerated(charIDToTypeID( "Lyr " ),charIDToTypeID( "Ordn" ),charIDToTypeID( "Trgt" ));
	descGrp.putReference(charIDToTypeID( "null" ), refGrp );
	executeAction( idGrp, descGrp, DialogModes.ALL );
	var resultLayers=new Array();
	
    for (var ix=0;ix<app.activeDocument.activeLayer.layers.length;ix++){resultLayers.push(app.activeDocument.activeLayer.layers[ix])}
	var id8 = charIDToTypeID( "slct" );
    var desc5 = new ActionDescriptor();
    var id9 = charIDToTypeID( "null" );
    var ref2 = new ActionReference();
    var id10 = charIDToTypeID( "HstS" );
    var id11 = charIDToTypeID( "Ordn" );
    var id12 = charIDToTypeID( "Prvs" );  
    ref2.putEnumerated( id10, id11, id12 );
	desc5.putReference( id9, ref2 );
	executeAction( id8, desc5, DialogModes.NO );
	return resultLayers;
}

I would recommend converting all the Layers to Smart Objects (if they are not already) before transforming. 

Does this help?

        @Stephen Marsh 

        very nice sir but i'm sorry
        This code converts the layers of the Smart Object and then Restrizelayer

        I want the specific layer code I need to perform more than one action on these specific layers
        for example
        - Change fonts for selected layers
        - Make a specific filter on the selected layers, etc.
        Thank you very much for your interest, appreciation and outstanding work

        You didn't mention that!

         

        So, is it just that you need code to apply a specific function* to multiple selected layers?

         

        * The function could be anything, you were just using resize as one example of many possible operations that need to be performed to multiple selected layers?

          The function getSelectedLayers seems antiquated, I suspect it precedes some changes that made evaluating the selected Layers easier. 

           

          when implemented on more than one layer, it gives a very different result from what I want

          What is that result and how does it differ from your expectations?
