Get the page size of the pdf from autolisp

[S_S_SS]

Hello every one 

I've a lisp that convert more pages from pdf file to autocad 

But i must make scale command reference to any dimension in the drawing to get the actual size of the page 

But if i get the pdf page size (A4, A3, A2.......) i can make the lisp decide the the scale required 

How can i get the pdf page size?? 

Thanks in advance
