When you say PdfDocument, do you mean
"writer.getDirectContent().getPdfDocument()"?
Before I forget to say it....THANK YOU for spending the time to help me
understand my issue and your willingness to share.

OK, I see that the values of the current and the next margins are stored

If you want to add a voucher using the current margin, you'd need to
find a way to ask PdfDocument for its bottom margin.
