An OCG can be used to hide all the content on a page (thus leaving it blank, or
with some sort of "this page intentially left blank" text), but can NOT
actually remove/hide the page itself from the viewer. OCGs can exist on any
set of pages as they are just objects that can be referenced from anywhere.
You are correct that templates can not be used with Reader, unless the file has
been Reader Extended/Enabled.

Subject: [iText-questions] OCG spanning multiple pages or template
Hi,
I have a requirement to hide multiple pages in a pdf based on certain actions
(possibly triggered from javascript). From reading the book and online resources
the two ways to do this is using OCG or templates. the latter would need the
end-user to have acrobat (am I right?). My users typically have just the reader.
Using an OCG,How would I make it span multiple pages and trigger hide/show
from javascript? I see that PdfLayer inherits the Pages fiek from pdfDictionary
but not sure exactly how to do this in code?
think this would be a standard-ish requirement. any pointers are much
appreciated.
thanks
