ImageResizer 水印未出现

Question

我有一个 Azure Function，它正在尝试使用 ImageResizer 3.4.3 版向现有图像添加水印。该函数执行无误，但未应用水印。这是代码，紧随 here:

private static void ApplyWatermark(Stream inputStream, string blobName)
{
    var imageConfiguration = Config.Current;
    var plugin = imageConfiguration.Plugins.Get<WatermarkPlugin>();
    if (plugin == null)
    {
        plugin = new WatermarkPlugin();
        plugin.Install(imageConfiguration);
    }
    plugin = imageConfiguration.Plugins.Get<WatermarkPlugin>();
    var imageLayer = new ImageLayer(imageConfiguration)
    {
        Path = HostingEnvironment.MapPath(_configuration.Get<string>("BadgeUrl")),
        Align = ContentAlignment.MiddleCenter
    };
    plugin.NamedWatermarks["badge"] = new Layer[]
    {
        imageLayer
    };
    inputStream.Position = 0;
    var outputStream = new MemoryStream();
    imageConfiguration.CurrentImageBuilder.Build(inputStream, outputStream,
        new ResizeSettings("watermark=badge"));
    outputStream.Position = 0;
    _blobStorageRepository.AddorUpdateAsync(_configuration.BlobStorageContainer,
        blobName, outputStream).Wait();
}

关于为什么不应用水印有什么想法吗？

Watermark 插件需要类似“~/azure/blobimage.jpg”的虚拟路径。它不接受可能位于应用程序根目录或已安装文件夹之外的物理路径。
