I have a .docx file that is created from a Telerik “DocxFormatProvider” included as an attachment here, it is not recognizing the watermark and show the image without watermark properties, I have tried converting the document from the online Aspose website

but got the same result the output is fine in MS Word but it’s not as expected after converting to pdf.
I am using Aspose.Word 21.1.0 and below is my code snippet

          var doc = new Aspose.Words.Document(data);
          doc.Save("output.pdf");

We have tested the scenario using the latest version of Aspose.Words for .NET 21.9 and have not found any issue with output PDF. Please check the attached output PDF files generated by MS Word and Aspose.Words. Both documents are same. 21.9.pdf (132.7 KB)
