Hello context-community,
I have an image as a layer and want it to place on every page of a book
with some offset.
My minexample:
\setlayer[mybg]
[hoffset=2cm, voffset=0.2cm, doublesided=yes] {\framed[frame=off,
width=2cm,
height=1cm]{\externalfigure[bilder_bearbeitet_png/32.png][width=\textwidth]}}
That works in principle, but I want the hoffset to be relative to the
cutspace/backspace: different on right and left page, such that the
layer is set equally on every page relative to the textbody.
In the example above I use "doublesided=yes", but that has no effect.
How to achieve proper double-sided behavior?
You have to set the content for the layer twice, once for
the left pages and a second time for the right pages.
\setuppagenumbering
[alternative=doublesided]
% \setupexternalfigures
% [directory=images_bearbeitet_png]
\definelayer
[backgroundimage]
[width=\paperwidth,
height=\paperheight,
state=repeat,
doublesided=yes]
\setupbackgrounds
[page]
[background=backgroundimage]
\setlayer
[backgroundimage]
[right]
[x=\backspace,
y=\dimexpr\topspace+\headerheight+\headerdistance\relax]
{\externalfigure[32.png]}
\setlayer
[backgroundimage]
[left]
[x=\cutspace,
y=\dimexpr\topspace+\headerheight+\headerdistance\relax]
{\externalfigure[32.png]}
\showframe [text] [text]
\starttext
\dorecurse{10}{\dontleavehmode\page}
\stoptext
