Define a layer that takes the whole page
<texcode>
\definelayer [mybg] % name of the layer [x=0mm, y=0mm, % from upper left corner of paper width=\paperwidth, height=\paperheight] % let the layer cover the full paper
</texcode>
Now you can put something in that layer:
<texcode>
\setlayer [mybg] % name of the layer [hoffset=1cm, voffset=1cm] % placement (from upper left corner of the layer) {\framed[frame=on, width=3cm, height=2cm]{LAYER}} % the actual contents of the layer
</texcode>
Now you can test the whole thing:
<texcodecontext source=yes>\setuppapersize[A10,portrait][A9,landscape] % A10 = 2.6x3.7cm -- compact example\setuparranging[2SIDE] % show both pages\showframe % So we can see the pages \definelayer [mybg] % name of the layer [x=0mm, y=0mm, % from upper left corner of paper width=\paperwidth, height=\paperheight] , % let the layer cover the full paper state=continue] % on all pages but the first one
\setupbackgrounds[page][background=mybg]
\setlayer [mybg] % name of the layer [hoffset=1cm0.3cm, voffset=1cm0.7cm] % placement (from upper left corner of the layer) {\framed[frame=on, width=3cm2cm, height=2cm]{LAYER}} % the actual contents of the layer
\starttext
\dorecurse{2}{\page[empty]} % for testing, to get 2 pages, 1st 2nd with layer, 2nd 1st without
\stoptext
</texcodecontext>
You may experience cases where the defined size of your layer is ignored and you can’t get linebreaking or multiple lines at all.
This is due to <cmd>setlayer</cmd> using <cmd>hbox</cmd> internally. You can work around the problem using <cmd>setlayerframed</cmd>:
This does not work:<texcodecontext source=yes>\showframe \definelayer[AddressBg][ x=20mm0mm,y=30mm0mm, width=65mm,height=30mm, state=start] % size is ignored!\setupbackgrounds[paper][ setups=ALayer, background=AddressBg, state=start]
