repeat layer recto pages

repeat layer recto pages

[jbf via ntg-context]

I want a particular layer to repeat on recto pages only, but I don't 
want this to happen in frontmatter, only in bodymatter.

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).

\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]

etc.

Any thoughts?

Julian

Hi Julian,

this is what you want:

  \startsectionblockenvironment[bodypart]
    \setupbackgrounds
      [rightpage]
      [background=butterfly]
  \stopsectionblockenvironment

> \startbodymatter

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

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?

Hi Julian,

I’m glad to read that it worked for you.

I didn’t realize that there was a "repeat" option in \definelayer.

I use "state", since it contains more values to be chosen from.

I guess "state=repeat" and "repeat=yes" get the same result.

Pablo
