How can I set the properties like "Author" and "Title" in a new PDF?

[PeterCodar]

Where can I find a code example to set all the possible properties for a new PDF?

Currently, the "Title", "Author", "Application" will be set automatically.
How can I delete them or set them to my own values and format string?

What about all the other PDF properties like "Subject", "Keywords", "Created", "Modified", "PDF producer".

For those looking for a code example how to write this 3 available properties into a new PDF using VB.NET:

...
     images.Write(PDFFileName, New Formats.PdfWriteDefines With
               {.Author = "My Author",
                .Producer = "My Producer",
                .Title = "My Title"})
...

Would be great if we could set "Subject", "Keywords", "Created", "Modified" and "Application" too.
