I am trying to clear several properties of an existing PDF document, but the keywords field doesn't get cleared when I also clear the subject and title fields. Is this a bug?
Here's some VB code that shows the issue:
Dim Document = New Aspose.Pdf.Document(FileName)
Document.Info.Title = ""
Document.Info.Subject = ""
Document.Info.Keywords = ""
If you comment out the second or third lines, then it works correctly. But, if you leave it as is, the keywords field isn't cleared - it simply adds a new blank keyword to the keywords list ("keywords" becomes " ; keywords"). Is there a way to remove the keywords from the PDF properties?
