// 下面的代码创建了 'documentFolder' 文件夹，其中包含 document.html，'css' 文件夹内有 'style.css' 文件，'images' 文件夹内有图像，'fonts' 文件夹内有字体。
// 'style.css' 文件将在末尾包含以下字符串 "/* This line is appended to stream manually by user */"
var savingCallbacks = new UserSavingCallbacks()
                          {
                              RootFolder = "documentFolder",
                              CssFolder = "css",
                              KeepCssStreamOpened = true,
                              ImagesFolder = "images",
                              FontsFolder = "fonts"
                          };
var options = new HtmlSaveOptions
              {
                  FontFaceTypes = FontFaceType.Ttf,
                  CssSavingCallback = savingCallbacks,
                  FontSavingCallback = savingCallbacks,
                  ImageSavingCallback = savingCallbacks
              };

if (!Directory.Exists(savingCallbacks.RootFolder))
{
    Directory.CreateDirectory(savingCallbacks.RootFolder);
}

string dataDir = RunExamples.GetDataDir_LoadingAndSaving();
var document = new Document(Path.Combine(dataDir, "Aspose.one"));

using (var stream = File.Create(Path.Combine(savingCallbacks.RootFolder, "document.html")))
{
    document.Save(stream, options);
}

using (var writer = new StreamWriter(savingCallbacks.CssStream))
{
    writer.WriteLine();
    writer.WriteLine("/* This line is appended to stream manually by user */");
}
