Javascript 如何将智能对象层中心与画布对齐？

我整天都在谷歌上搜索，想找到一种方法，通过脚本将转换为智能对象中心的层与画布对齐，但到目前为止还没有找到解决方案。我最终得到了下面的代码，但它不起作用。有人能帮忙吗

var baseFile = new File(openDialog()); //open base JPEG file
var workFile = new File(openDialog()); //open work JPEG file
var baseDoc = app.open(baseFile);
var workDoc = app.open(workFile);

createSO(workDoc.layers[0]);
workDoc.resizeImage(280,280);
workDoc.artLayers[0].duplicate(baseDoc, ElementPlacement.INSIDE);
app.activeDocument = baseDoc;

var Hoffset = (baseDoc.width - workDoc.width) / 2;
var Voffset = (baseDoc.height - workDoc.height) / 2;
baseDoc.layers[1].position = Array(Hoffset, Voffset);

function createSO(){
    var doc = app.activeDocument;
    var idnewPlacedLayer = stringIDToTypeID( "newPlacedLayer" );
    executeAction( idnewPlacedLayer, undefined, DialogModes.NO );
    return doc.activeLayer;
}

我想你可以这样简化一下：

var baseFile = new File(openDialog()); //open base JPEG file
var workFile = new File(openDialog()); //open work JPEG file
var baseDoc = app.open(baseFile);
var workDoc = app.open(workFile, undefined, true);

workDoc.resizeImage(280, 280);
var duplicated = workDoc.artLayers[0].duplicate(baseDoc, ElementPlacement.INSIDE);
var Hoffset = (baseDoc.width - workDoc.width) / 2;
var Voffset = (baseDoc.height - workDoc.height) / 2;

app.activeDocument = baseDoc;

duplicated.translate(Hoffset, Voffset);

这里的重点是使用翻译方法；但是，您也可以避免使用app.open的第三个参数（即asSmartObject）创建createSO函数
