Thanks for your inquiry and sorry for the delayed response.
While using the latest version of Aspose.Words i.e. 11.9.0, I have rendered your ‘GIS Enquiry System User Guide(2).DOCX’ to Pdf format; I then opened the produced Pdf with Adobe Acrobat X version 10.2.0 and Foxit Reader v5.1 and was unable to observe any such problem on my side. It seems the attached ‘Document.pdf’ was first produced using Aspose.Words v11.3.0 and then modified by another third party control iTextSharp 5.1.3. Could you please also double check if you are using the latest version (11.9.0)? You can dynamically check if you’re referencing the correct DLL by using the following code snippet:
System.Reflection.Assembly assemblies = AppDomain.CurrentDomain.GetAssemblies();
foreach (System.Reflection.Assembly assembly in assemblies)
System.Reflection.AssemblyName assemblyName = assembly.GetName();
Console.WriteLine("Aspose.Words Version Number: " + assemblyName.Version.ToString());
Moreover, I have attached the Pdf file that is produced on my side using Aspose.Words v11.9.0 here for your reference. If we can help you with anything else, please feel free to ask.
