Psd文件解析出来的图层对象Layer，无法序列化

对不起，我没有明白你的意思吗？您能解释一下它的意思吗？可以序列化但不能反序列化。

0.场景需求：PsdImage对象-》（(PsdImage) Image.load(sourceFileName,loadOptions)，存储为byte[]，转存new String(bytes, “UTF-8”)，持久化存储，然后再String->byte[]->PsdImage，进行图层的操作（文本层文字替换、图片层图片替换等）。
1.源代码：

public static void main(String[] args) throws FileNotFoundException 
{
    License license = new License();
    String licFileDir = "E:\\mysite\\openproj\\Aspose.PSD-for-Java\\Examples\\src\\main\\resources\\Lic\\Aspose.Total.Product.Family.lic";
    license.setLicense(licFileDir);
    String dataDir = "E:\\mysite\\openproj\\Aspose.PSD-for-Java\\Examples\\src\\main\\resources\\PSD\\";
    String sourceFileName = dataDir + "nvwangJy.psd";
    String exportPath = dataDir + "nvwangNewTextUpdateResult.png";
    PsdLoadOptions loadOptions = new PsdLoadOptions();
    //Try this
    //loadOptions. setLoadEffectsResource(true);
    PsdImage image1 =(PsdImage) Image.load(sourceFileName,loadOptions);

    byte[] layerBytes;
    MemoryStream layerMem = new MemoryStream();
    OutputStream dstStream = layerMem.toOutputStream();
    image1.save(dstStream, new PsdOptions());
    layerBytes = layerMem.toArray();
    //layerMem = new MemoryStream(layerBytes);
    InputStream inputStream = new ByteArrayInputStream(layerBytes);
    PsdImage image = new PsdImage(inputStream);

    for(int i=0; i < image.getLayers().length; i++ )
    {
        Layer layer = (Layer) image.getLayers()[i];
        System.out.println(i + "DisplayName:" + layer.getDisplayName() + "name:" + layer.getName());
        if (i == 11 && image.getLayers()[i] instanceof TextLayer)
        {
            TextLayer textLayer = (TextLayer)image.getLayers()[i];
            Point leftTopCoordinate = new Point();
            leftTopCoordinate.setX(textLayer.getLeft());
            leftTopCoordinate.setY(textLayer.getTop());
            textLayer.updateText("靠你就是我\r我的\r你的", leftTopCoordinate, ((TextLayer)textLayer).getFont().getSize(), ((TextLayer)textLayer).getTextColor());
        }
    }
    PngOptions options = new PngOptions();
    options.setColorType(PngColorType.TruecolorWithAlpha);

    image.save(exportPath,options);
}
