Can't be done. Not part of pdf, unless one goes to quite some troubles
defining all annotations as widgets while using the default button
things. Far from ideal. Just generate a nice A4 version as parallel
document.

It completely depends on what you want to do. When you mix text and
figures in the way I think you do, I would not use backgrounds, because
that way you have no way of telling where the text should start. Just
use something like:

\externalfigure[name][factor=max,height=.6\textheight]

which gives you name scaled to the max, unless the height
>.6\textheight

Niet afdrukbare buttons in pdftex?

[Gilbert van den Dobbelsteen]

Hi there,

I need to put a button on a page which is available normally, but does 
not appear on the printed output. 

Does anybody know how this can be done in \CONTEXT?
I couldn't find it in core-ref, though I guess it is pretty straight 
forward.

Another one: I am creating A4 single page .pdf files from png scans. 
Besides the scan some text (and the button mentioned before) needs to 
be present. To accomplish this I setup the png scan as a page-
background (haven't done that yet but I use the s-pre-xx as an example)
so normal text can be present on the page. Is this the way to do that, 
or are there other methods which I didn't see?

Gilbert.
