Re: [NTG-context] repeat layer recto pages
Muchas gracias Pablo, that was most helpful, and of course it works.
The particular part that I was missing (there was already
alternative=doublesided in the preamble) of course was the
\startsectionblockenvironment[bodypart], so thanks for highlighting that.
I was also a bit confused about the difference between state=repeat and
repeat=yes, and I can see that both do work in the snippet you gave me,
so perhaps there is no difference between these?

This is what I have done, just before the first chapter after
\startbodymatter (but unsuccessfully; the layer repeats for every page
at the moment. I must have omitted something).
Hi Julian,
this is what you want:
\startsectionblockenvironment[bodypart]
\setupbackgrounds
[rightpage]
[background=butterfly]
\stopsectionblockenvironment
\startbodymatter
\setupbackgrounds
[rightpage]
[background=butterfly]
\startchapter[title={Chapter title}]
\definelayer[butterfly]
[x=0mm, y=0mm,repeat=yes,width=\paperwidth, height=\paperheight]
\setlayer[butterfly]
[hoffset=.99\textwidth, voffset=1cm]
{\externalfigure[bfly.jpg][width=1.5cm]}
\setupbackgrounds[page][background=butterfly]
The last line adds backgrounds to every page. And without doublesided,
there are not right and left pages.
And you don’t need the \define and \setlayer after \startchapter.
A complete sample would read:
\setuppagenumbering[alternative=doublesided]
\definelayer[butterfly][state=repeat]
\setlayer[butterfly]
[hoffset=.99\textwidth, voffset=1cm]
{butterfly}
\startsectionblockenvironment[bodypart]
\setupbackgrounds
[rightpage]
[background=butterfly]
\stopsectionblockenvironment
\def\rubbish%
{\dorecurse{2}
{\chapter{Chapter}
\dorecurse{25}{\input knuth}}}
\starttext
\startfrontmatter
\rubbish
\stopfrontmatter
\startbodymatter
\rubbish
\stopbodymatter
\startappendices
\rubbish
\stopappendices
\startbackmatter
\rubbish
\stopbackmatter
\stoptext
I hope it helps,
Pablo

[NTG-context] Concerning \installparameterhashhandler and family
Hi. Reading at mult-aux.mkxl, I've seen command handlers define, among others, \installparameterhashhandler, However, in files such as those related with symbol management, only \installparameterhandler and \installsetuphandler are. When writing basic modules, sometimes only the "raw" macros above are actually needed. So, what are "parameterset", "hashhander", "rootparameterhandler", etc. for? Where would they ease module writing? Thank you a lot and sorry for the long question. Best regards, Jairo ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___
