[NTG-context] layers for odd and even pages

[Pablo Rodriguez]

Dear list,

I have the following sample:

\setuppapersize[A5]
\setuppagenumbering[alternative=doublesided,location=]
\definelayer[testodd][state=start]
\setlayer[testodd]{Odd page}
\definelayer[testeven][state=continue]
\setlayer[testeven]{Even page}
\setupbackgrounds[page][background={testodd, testeven}]
\starttext
\dorecurse{5}{\dorecurse{\recurselevel}{\input zapf\par}\page[right]}
\stoptext

I need different layers in even and odd pages and that they are hidden
on empty pages.

Which is the way to do it?

Many thanks for your help,


Pablo
