PDF - 'ImageMalformed: NoEnabledDecoderFound

[AnujAngooral]

I am trying to extract the image from a PDF file. It used to work in ImageResizer with PdfRendererPlugin.

imageResizer = new Lazy<Config>( () => { var config = new Config(); new PdfRendererPlugin().Install(config); return config; }); var job = new ImageJob(sourceStream, destStream, new Instructions { OutputFormat = OutputFormat.Jpeg, Width = 1024 }); imageResizer.Value.CurrentImageBuilder.Build(imageJob);

How can I achieve the same in the Imageflow with .net standard? I tried the following code. But it gives error: Imageflow.Bindings.ImageflowException: 'ImageMalformed: NoEnabledDecoderFound: No ENABLED decoder found for file starting in [25, 50, 44, 46, 2D, 31, 2E, 33, D, 25, E2, E3]

`string imageSourcePath = "https://mywebsite/test.pdf";

        var request = HttpWebRequest.Create(imageSourcePath);
        using (var response = (HttpWebResponse)request.GetResponse())
        {
            using (var responseStream = response.GetResponseStream())
            {
                MemoryStream sourceStream = new MemoryStream();
                responseStream.CopyTo(sourceStream);
                sourceStream.Seek(0, SeekOrigin.Begin);

     using (var b = new ImageJob())
                {
                    try
                    {

                        var r = await b.Decode(sourceStream, false).ResizerCommands("width=1024")

                           .EncodeToBytes(new MozJpegEncoder(100, true)).Finish().InProcessAsync();

                        var bytes = r.First.TryGetBytes();
                        using (var stream = new MemoryStream(bytes.Value.Array))
                        {

                            Image img = Image.FromStream(stream);

                            img.Save(@"D:\temp" + "\\" + Guid.NewGuid() + ".Jpeg", ImageFormat.Jpeg);
                        }

                    }
                    catch (Exception ex)
                    {
                        Console.WriteLine(ex.Message);
                    }
                }

            }
        }

Imageflow does not have a PDF decoder for security reasons; they are easy to exploit.
