Paulo,
I wanted to thank you for the assistance you provided - I ended up
converting everything over to use PdfContentByte rather than mixing
document.add() with PdfContentByte. All works well.
Your dedication and willingness to help are greatly appreciated and
I can not be the only one with such an opinion.
Thanks again,
Jim

Whatever you do with PdfContentByte will never cause a new page. If you
have a new page it was caused by the Document.add().
