Hi
Thanks for your reporting this problem to us. I managed to reproduce the problem. I have logged this problem to our defect database as issue # 4129. Please expect a reply before the next hotfix (within 2-3 weeks). We might just fix it by then or provide more information
Also note that Aspose.Words.Viewer namespace is currently in beta.
Best regards.

We are happy to tell you that the new Rendering Engine has replaced the “old Viewer Beta”. The Rendering Engine can print, save as images or draw onto .NET Graphics object any document page.

Please see Aspose.Words documentation to learn more about new features.

Saving to image

In additional, new Rendering engine allows you to convert Word document to PDF directly (without using Aspose.Pdf).

The latest version of Aspose.Words is available for download from downloads section or from NuGet
