Thanks for the reply.
yes you are right I really dont need to shrink it. Only scale it down wrt to
the new page size. Is that what you are saying?
I am not inclined to the image idea since, it wont retain all the
interactive features, without a lot of work as you pointed out.
Basically I am trying to add headers and footer to every page. Now it so
happens that in some pages, the bottom/top margins are very low and this
content overlaps my footer/header table
So I thought, lets try the idea, where in we scale/shrink the page to a
smaller size including the form fields, without loosing their functionality.
This is more difficult than I thought.
is there a way to detect this overlap .. given a reference rectangle? Then I
can possibly increase the height of the document and add my contents? Is
this a feasible idea?
Thanks again for your time.
Subhro.
