Support for Optional Content Groups

Support for Optional Content Groups

[Chris Chapman]

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-only-print-only-in-pdf

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 ;)

Thanks in advance,

Chris Chapman

You can test if the layers are hidden when you print the following example, I tried the Adobe Reader on my Mac and they where still visible.

\setupinteraction[state=start]

\defineoverlay[PageBackground] [\startMPcode fill fullsquare xyscaled(OverlayWidth,OverlayHeight) withcolor \MPcolor{orange} ; \stopMPcode]
\defineoverlay[FrameBackground][\startMPcode fill fullsquare xyscaled(OverlayWidth,OverlayHeight) withcolor \MPcolor{green} ;  \stopMPcode]

%\setupbackgrounds[page][background=color,backgroundcolor=orange] % doesn’t work because you can only hide the background together with the text
\setupbackgrounds[page][background=PageBackground]

\setupviewerlayer[printable=no]

\defineviewerlayer[mylayer]

%\showlayoutcomponents % use this to enable/disable certain text areas

\starttext

\input knuth

\startviewerlayer[mylayer]
\input ward
\stopviewerlayer

\input tufte

\startframedtext[width=max,background=FrameBackground]
\input weisman
\stopframedtext

\stoptext

(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.

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 tried this today and report the results, curious to see how on my Apple Macintosh the following readers cope with this:

- Adobe Acrobat Reader DC version 15.016.20041 (most recent): does as is intended
- Apple Preview: shows all four, definitely a bad score for Apple here.

Framing multiline equations

[L.S.-Soc&Gam]

Hello together,

I'm having trouble framing multiline equations. Problem is that either I 
get an error or the equation gets framed while the multiline is 
converted into a single line. Here is my code:

---------------------
\starttext

\startformula                                 <- works like a charm
\mframed[offset=1mm,loffset=3mm,roffset=3mm]
     {a + b = c}
\stopformula

\startformula \startalign                         <- that's an example 
multiline equation
\NC c - a = \NC b \NR                            <- unframed it works
\NC d + c - b = \NC a \NR
\stopalign \stopformula

\startformula \framed{\startalign <- \mframed gives an error. \framed 
works, but then the eq
\NC c - a = \NC b \NR           <- gets converted into a single line eq.
\NC d + c - b = \NC a \NR
\stopalign} \stopformula

\stoptext
---------------------

I tried to place \mframed at different locations. But the example above 
is the only one that doesn't give an error.
How would an experienced CTX user frame multiline equations?
I think it would work with natural TABLES. But i would only use that 
way, when nothing else works...


Greetings, Seba

next beta:

\starttext

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

\startformula \startalign
     \NC c - a     = \NC b \NR
     \NC d + c - b = \NC a \NR
\stopalign \stopformula

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

\startformula
\mframed
     [offset=1mm,loffset=3mm,roffset=3mm] {
         a + b = c
     }
\stopformula

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

\startformula
\mframed
     [offset=1mm,loffset=3mm,roffset=3mm] {
         \startalign
             \NC c - a     = \NC b \NR
             \NC d + c - b = \NC a \NR
         \stopalign
     }
\stopformula

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

\stoptext

i'll sort out spacing later
