[iText-questions] Landscape or Portrait

[AMOL]

 
Hello
Well i m dealing with a layout problem

Scenario:I am creating overlay watermark pdf
(XML->XSL-FO->PDF) to overlay it on source PDF document.
Now i can have my source document either Portarit or
Landscape....and accordingly I have to create watermark PDF.
I am using jdk1.3.1,itext and fop(for XSL-Fo to PDF Convesion).
Can itext provide any api by which i can get the page layout
dynamically?
Any help in this context will be greatly appreciated.
Thnaks
