Merging background

Merging background

[Cecil Westerhof]

I have a template for a letter in which I use \setupbackgrounds. I
also have a tenplate for a watermark which also uses
\setupbackgrounds. The background from the last include is used. Is
there a way to merge the backgrounds?

\setupbackgrounds[page][background={template,watermark}]

In my letter template I now do:
    \setupbackgrounds[page][background={myAddr,WatermarkOverlay}]

That even works if the watermark template is not included. So, so far so good.

But I was wondering if it could be generalized. I was thinking about
the following. A variable backgroundList is defined and in every
template where layers are defined, those layers are added to
backgroundList. And then the following statement is used:
    \setupbackgrounds[page][background=\@backgroundList]

Is something like this possible?

Perhaps you're looking for something like this:

That means: a template adds a background.

Cheers, Peter

Works like a charm. In t-defaults.tex I have:
    \setupbackgrounds[page][state=start]

In t-watermark.tex I have:
    \expandparameters
    \setupbackgrounds[page][background={\currentvalue,WatermarkOverlay}]

In t-privebrief.tex I have:
    \expandparameters
    \setupbackgrounds[page][background={\currentvalue,myAddr}]

And in my document I have:
    \usemodule[defaults]
    \usemodule[watermark]
    \usemodule[privebrief]

And both backgrounds are displayed.
