[iText-questions] How to display page numbers if more than 1 page only?

[Eric B.]

Hi, I'm trying to figure out how to do this and am not sure of the proper technique to use.  I'd like to display a footer "Page X of Y" only if there are more than 1 pages in the document.   I realize I need to use PageEvents (onEndPage and onCloseDocument) to create this footer and template for "Y", but how do I only enable it if there are more than 1 pages in the document?  ie:  if only 1 page, I don't want anything to be displayed.   Thanks! Eric
