Hello,
I have a document with different backgrounds (external PDFs) for even and
odd pages.
I have found how to get the right background on the right page.
\defineoverlay
[papier]
[{\ifodd\realpageno {\externalfigure[voorkant][width=\overlaywidth,heig
ht=\overlayheight]}
\else {\externalfigure[achterkant][width=\overlaywidth,height=\overlay
height]}
\fi}]
My problem is that the different backgrounds require setting a different
topspace and height for the page.
My question: Where can I place the different setuplayout[topspace=..,height
=..] commands so the are evaluated again for every page (different for
even and odd pages)?
Thanks,
Joop

You can use:
\setupbackgrounds
[leftpage]
[background=LeftPage]
\defineoverlay
[LeftPage]
[\vbox to \overlayheight
{\vskip 1.23cm
\externalfigure[...][]}]
and alike, so: put the fig in a box [watch the leftpage/rightpage option,
it saves you some if's]
i'm my local alpha release i have multiple layouts [page dependent] so that
may be an option for the future

Sorry Hans, This does not give the desired effect.
The right page has a Big header, actually filled in with an other MP
overlay for a lot of fixed information and a footer. The overlays are
realy full A4 scans of some form that I cannot recreate in
ConTeXt/MetaFun. That's the real reason for [width=\overlaywidth,height=\ov
erlayheight].
I did not want to push the overlay down the page, which is what your code
does, but I wanted to make the text area smaller (equivalent to the
setuplayout[topspace=...] setting) so text is not set on top of the
background. The left page has a smaller header and a different footer from
the right page.
Basically I wanted to have de topspace set to different values for left
and right page (really back and front of non-arranged A4). I cannot figure
out where to hook in the topspace adjustment. Is there some hook that is
executed for every new page? I do not force the page with \page otherwise
that would be the place...
\defineoverlay
[vulling]
[{\ifodd\realpageno {\MPfillin{\overlaywidth}{\overlayheight}}\fi}]
\defineoverlay
[voorkant]
[{\externalfigure[voorkant][width=\overlaywidth,height=\overlayheight]}
]
\defineoverlay
[achterkant]
[{\externalfigure[achterkant][width=\overlaywidth,height=\overlayheight
]}]
\setupbackgrounds
[rightpage]
[background={voorkant,vulling}]
\setupbackgrounds
[leftpage]
[background=achterkant]
\setupbackgrounds
[state=repeat]
How do I get the leftpage and right page to alternate repeatedly? That
last statement is ineffective.

Sounds like THE solution, but I understand that I'll have to wait a bit
longer for that... ;-)
