Hello all,
I'm typesetting a newsletter where a few fixed-place elements can be
added dynamically.
I have found way to do this by defining a layer that is not part of
the regular backgrounds, so when I want to add it to a specific page I
do something like:
\setupbackgrounds[page][background=speciallayer,state=start]
\setlayer[speciallayer]{extra content}
and this is actually done in a macro/environment (\startsomething
extracontent \ stopsomething) so that it's easier to manage on a
per-use case.
This works very well, but now I find myself in the situation where I
have *two* such layers. So I have special1 and special2,
and a \startsomething1 .... \stopsomething1 this enables special1
but a \startsomething2 ... \stopsomething2 enables special2 ... and
since this is done via setupbackgrounds whichever comes second
DISABLES the other.
So is there a way to specify that the background specified in a
setupbackgrounds should APPEND rather than REPLACE the existing
background specification for a page?
Cheers,
Giuseppe Bilotta
