Re: [NTG-context] Support for Optional Content Groups

      Thanks Hans and Wolfgang! Yes, it looks like most PDF viewers don't handle layers right now, but I'm fine with Acrobat for this use case.

I am new to ConTeXt (coming from LaTeX), and am really impressed. Great
work!
I am working on a document that has layers that I want to be screen-only,
similar in approach to this:
http://tex.stackexchange.com/questions/167846/implementing-full-page-screen-...
I am assuming that Optional Content Groups would be the best way to do
this. How would I set something up like this in ConTeXt/LuaTeX? I know I
could make a screen-only version and a print version of the output pdf,
but I want to have my cake and eat it too ;)
(also see wolfgangs mail)
I tried this in acrobat:
\defineviewerlayer[visibleandprint]      [printable=yes,state=start]
\defineviewerlayer[visibleandnotprint]   [printable=no, state=start]
\defineviewerlayer[notvisibleandprint]   [printable=yes,state=stop]
\defineviewerlayer[notvisibleandnotprint][printable=no, state=stop]
\setupinteraction[state=start]
\starttext
\startviewerlayer[visibleandprint]       visible and print
\stopviewerlayer \blank
\startviewerlayer[visibleandnotprint]    visible and not print
\stopviewerlayer \blank
\startviewerlayer[notvisibleandprint]    not visible and print
\stopviewerlayer \blank
\startviewerlayer[notvisibleandnotprint] not visible and not print
\stopviewerlayer \blank
\stoptext
and found out that we need an extra piece of info for acrobat to be
happy. I'll upload a beta with that addition.
I wonder if other viewers handle layers well.
