Some JPG files convert to PDF not working

I am using Aspose.pdf to convert JPG to pdf, for most files it works. but some jpg file seems not working. I have attached the jpg file to see if someone can convert to pdf. Below is my code.

            case ".jfif":
            case ".jpe":
            case ".jpg":
            case ".jpeg":
            case ".tif":
            case ".png":
            case ".gif":
                pdfDocument = new Aspose.Pdf.Document();
                asposePdfImage = new Aspose.Pdf.Image();
                Bitmap bitmap = new Bitmap(postFile.InputStream);
                asposePdfImage.ImageStream = postFile.InputStream;

                pdfDocument.Pages[1].PageInfo.Height = bitmap.Height;
                pdfDocument.Pages[1].PageInfo.Width = bitmap.Width;
                pdfDocument.Pages[1].PageInfo.Margin.Left = 1;
                pdfDocument.Pages[1].PageInfo.Margin.Top = 1;
                pdfDocument.Pages[1].PageInfo.Margin.Bottom = 1;
                pdfDocument.Pages[1].PageInfo.Margin.Right = 1;

Great, after upgrade Aspose.pdf from 18.7 to 18.9.1, the issue has been resolved. thanks, Farhan.
