Resize a layer

This is fantastic! The result is amazing.

Great support pixxxel schubser, you're always saving me here and in the Illustrator community. Thank you.

Here is the result:

var dialog = new Window("dialog","Resize Layers");   
    dialog.preferredSize.width = 200;   
    dialog.preferredSize.height = 80;   
    dialog.orientation = "column";   
    dialog.alignChildren = ["center","top"];   
    dialog.spacing = 10;   
    dialog.margins = 16;   
  
  
var group1 = dialog.add("group");   
    group1.orientation = "row";   
    group1.alignChildren = ["left","center"];   
    group1.spacing = 10;   
    group1.margins = 0;   
  
  
var statictext1 = group1.add("statictext");   
    statictext1.text = "New width";   
  
  
var edittext1 = group1.add("edittext");   
    edittext1.preferredSize.width = 40;   
    edittext1.preferredSize.height = 25;   
  
  
var statictext2 = group1.add("statictext");   
    statictext2.text = "centimeters";   
  
  
var button1 = group1.add("button");   
    button1.text = "OK";   
    button1.preferredSize.width = 80;   
    button1.preferredSize.height = 25;   
    button1.justify = "center";   
  
  
  button1.onClick = function(){  
        var startRulerUnits = app.preferences.rulerUnits;  
        app.preferences.rulerUnits = Units.CM;  
        var aDoc = activeDocument;  
        var bds = aDoc.activeLayer.bounds;  
        var w = bds[2].value - bds[0].value;  
        var edittext_width = edittext1.text*1;  
        var f = edittext_width*100/w;  
        aDoc.activeLayer.resize(f, f, AnchorPosition.MIDDLECENTER);  
        app.preferences.rulerUnits = startRulerUnits;     
        app.refresh();
    }
   
  
dialog.show();
