All data in page is not converted to image using ExportAsImage method of PdfLoadedDocument class

I am using ExportAsImage to convert first page of pdf file to image. But all data in first page is not converted to image. Look like issue of multiple layer in pdf page. 

If I use Smallpdf.com tool to first convert pdf to image and then again convert to pdf and then use ExportAsImage method the it work fine.  

using (PdfLoadedDocument loadedDocument = new PdfLoadedDocument(path))
            {
                          Image extractedImage;
             
                        extractedImage = loadedDocument.ExportAsImage(0);
          }

sample pdf is also attached 

I am using version 15.3460.0.26

  • Windows - Syncfusion.EJ2.PdfViewer.AspNet.Core.Windows
  • Linux - Syncfusion.EJ2.PdfViewer.AspNet.Core.Linux
