You can possible use setups and use \doifoddpageelse to set the
layers. See

Thanks a lot. I don't know if using presets is actually
going to reduce the coding, though.
In the mean time, I've found that layers have a doublesided
option. This apparently allows you to override the
left/right settings of a layer, so I tried
\definelayer[title][
x=\dimexpr\backspace+\wdall-\wdtit,
y=\topspace,
width=\wdtit,
height=\httit,
state=repeat,
doublesided=true,
]
\setuplayer[lefttitle][
x=\backspace,
]
\definelayer[desc][
x=\backspace,
y=\topspace,
width=\wddesc,
height=\htdesc,
state=repeat,
doublesided=true,
]
\setuplayer[leftdesc][
x=\dimexpr\backspace+\wdall-\wddesc,
]
\definelayer[figs][
x=\dimexpr\backspace+\wdall-\wdfig,
y=\dimexpr\topspace+\makeupheight-\htfig,
width=\wdfig,
height=\htfig,
]
\setuplayer[leftfigs][
x=\backspace,
]
\setupbackgrounds[page][background={color,title,desc,figs},backgroundcolor=elux-ultralight]
However, the 'main' setup is always used, the left one is
never used. Am I doing something wrong?
Apparently, I mistook what the doublesided option does for
layers. I've currently solved the problem in the following
way:
\definelayer[test][doublesided=yes]
\setlayer[test][odd][..,..=..,..]{content}
\setlayer[test][even][..,..=..,..]{content}
Wolfgang
\unexpanded\def\titlexpos{%
\ifodd\realpageno\dimexpr\wdinside+\wdall-\wdtit\else\wdinside\fi
}
\definelayer[title][
x=\titlexpos,
y=\topspace,
width=\wdtit,
height=\httit,
]
\unexpanded\def\descxpos{%
\ifodd\realpageno\wdinside\else\dimexpr\wdinside+\wdall-\wddesc\fi
}
\definelayer[desc][
x=\descxpos,
y=\topspace,
width=\wddesc,
height=\htdesc,
]
\unexpanded\def\figsxpos{%
\ifodd\realpageno\dimexpr\backspace+\wdall-\wdfig\else\wdinside\fi
}
\definelayer[figs][
x=\figsxpos,
y=\dimexpr\topspace+\makeupheight-\htfig,
width=\wdfig,
height=\htfig,
]
\setupbackgrounds[page][background={color,title,desc,figs},backgroundcolor=elux-ultralight]
However, this solution doesn't strike me as particularly
elegant. I've seen in page-lyr.tex that support for
left/right layers is currently in progress, but if I read
the code correctly it just creates three layers (name,
leftname, rightname) and they have to be filled
individually. It would be nice to have a simpler interface
to repeated layers with position recalculated on each page.

Indeed, but if I want both sides to always have the same
content, I need to double-code every content insertion, or
write a macro to do that for me. It just moves the trickery
somewhere else :)
My expectation was that when \setlayer is used without
specification on a doublesided layer, it would set the
content for both sides. Alternatively, a way to specify
(even via presets) a position which is page-parity dependent
would be a good thing.

[NTG-context] Symmetrical layer positioning?
Hello all, is there a secret power switch to tell ConTeXt that a particular layer has different positioning depending on wether it's on a left or right page? I can of course do it manually, either by changing the layer position on each page or by using two layers instead of one, but I wanted to know if there was a more straightforward way that I was missing. -- Giuseppe Oblomov Bilotta ___ 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://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___
