place embedded and scale image in jsx

Hi all,

I have script to replace the smart object image and I just want to scale it before image got replace.. below is the script:-

// replace smart object’s content and save psd;
    // 2011, use it at your own risk;
    #target photoshop
    if (app.documents.length > 0) {
    var myDocument = app.activeDocument;
    var theName= myDocument.name.match(/(.*)\.[^\.]+$/)[1];
    var thePath = myDocument.path;
    var theLayer = myDocument.activeLayer;
    // psd options;
    psdOpts = new PhotoshopSaveOptions();
    psdOpts.embedColorProfile = true;
    psdOpts.alphaChannels = true;
    psdOpts.layers = true;
    psdOpts.spotColors = true;
    // check if layer is smart object;
    if (theLayer.kind != "LayerKind.SMARTOBJECT") {alert ("selected layer is not a smart object")}
    else {
    // select files;
    if ($.os.search(/windows/i) != -1) {var theFiles = File.openDialog ("please select files", "*.png,*.jpeg,*.jpg", true)}
    else {var theFiles = File.openDialog ("please select files", getFiles, true)};
    if (theFiles) {
        //alert(theFiles);
    // work through the array;
              for (var m = 0; m < theFiles.length; m++) {
    // replace smart object;
                        theLayer = replaceContents (theFiles, theLayer);
                       
                        var theNewName = theFiles.name.match(/(.*)\.[^\.]+$/)[1];
    //Raise color picker for Back cover;
    try {
    app.activeDocument.activeLayer = app.activeDocument.layers[app.activeDocument.layers.length - 1];
   
    // =======================================================
    var idsetd = charIDToTypeID( "setd" );
    var desc7 = new ActionDescriptor();
    var idnull = charIDToTypeID( "null" );
    var ref2 = new ActionReference();
    var idcontentLayer = stringIDToTypeID( "contentLayer" );
    var idOrdn = charIDToTypeID( "Ordn" );
    var idTrgt = charIDToTypeID( "Trgt" );
    ref2.putEnumerated( idcontentLayer, idOrdn, idTrgt );
    desc7.putReference( idnull, ref2 );
    var idT = charIDToTypeID( "T   " );
    var desc8 = new ActionDescriptor();
    var idClr = charIDToTypeID( "Clr " );
    var idsolidColorLayer = stringIDToTypeID( "solidColorLayer" );
    desc7.putObject( idT, idsolidColorLayer, desc8 );
    executeAction( idsetd, desc7, DialogModes.ALL );
    } catch (e) {};
    //save jpg;
                        myDocument.saveAs((new File(thePath+"/"+theName+"_"+theNewName+".psd")),psdOpts,true);
                        }
              }
    }
    };
    ////// get psds, tifs and jpgs from files //////
    function getFiles (theFile) {
         if (theFile.name.match(/\.(psd|tif|jpg|jpeg)$/i) != null || theFile.constructor.name == "Folder") {
              return true
              };
         };
    ////// replace contents //////
    function replaceContents (newFile, theSO) {
    app.activeDocument.activeLayer = theSO;
    // =======================================================
    var idplacedLayerReplaceContents = stringIDToTypeID( "placedLayerReplaceContents" );
        var desc3 = new ActionDescriptor();
        var idnull = charIDToTypeID( "null" );
        desc3.putPath( idnull, new File( newFile ) );
        var idPgNm = charIDToTypeID( "PgNm" );
        desc3.putInteger( idPgNm, 1 );
    executeAction( idplacedLayerReplaceContents, desc3, DialogModes.NO );
        return app.activeDocument.activeLayer
    };

I searched a lot, but didnt find anything about it..
