Dear all,
I need to have a special layout, in which a number (which is not a page number nor a section number or such) is printed in big size on the right when the pagenumber is even (that is on a leftpage) and printed on the left when the pagenumber is odd (that is a rightpage). With the help of examples gleaned here and there in the manuals, I came up with the following minimal example:
%%%% begin
\setupcolors[state=start]
\setuppagenumbering[location=footer,alternative=doublesided]
\definelayer[NumberRight][width=\paperwidth,height=\paperheight]
\definelayer[NumberLeft][width=\paperwidth,height=\paperheight]
%\showframe
\define[1]\myNumber{%
\setlayer[NumberRight][preset=righttop,voffset=45mm,hoffset=3mm,reset] % without reset the problem is the same
{\offset[location=rt,rightoffset=-3mm]
{\tlap{\startcolor[darkgreen]
\switchtobodyfont[ss]
\scale[height=30mm,width=22mm]{#1}
\stopcolor}
}
}
\setlayer[NumberLeft][preset=lefttop,voffset=45mm,hoffset=25mm,reset] % without reset the problem is the same
{\offset[location=tl,leftoffset=-3mm]
{\tlap{\startcolor[darkgreen]
\switchtobodyfont[ss]
\scale[height=30mm,width=22mm]{#1}
\stopcolor}
}
}
}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Maybe the problem is here?
\setupbackgrounds[leftpage] [background=NumberRight]
\setupbackgrounds[rightpage][background=NumberLeft]
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\starttext
\dorecurse{4}{\myNumber{#1}\input knuth.tex \page}
\dorecurse{4}{\myNumber{#1}\dorecurse{5}{\input knuth.tex }\page}
\stoptext
%%%%% end
The problem is that in some cases (for instance on pages 2, 3, 4 of the above example) the big numbers are overprinted.
In particular the behavior seems not to be the same on all pages, that is after the two \dorecurse above.
I guess my lack of knowledge in using and setting layers is the cause, but can anyone tell me please what am I doing wrong?
This problem arises in a document in which I have to use mkiv, but in mkii one ha the same result.
Thanks in advance and best regards: OK

Good example!
\setupcolors[state=start]
\setuppagenumbering[location=footer,alternative=doublesided]
\definelayer[Number][width=\paperwidth,height=\paperheight,doublesided=yes]
\define[1]\myNumber
{\setlayer[Number][odd]
[preset=righttop,voffset=45mm,hoffset=3mm]
{\offset[location=rt,rightoffset=-3mm]
{\tlap{\color[darkgreen]{\scale[height=30mm,width=22mm]{\ss#1}}}}}%
\setlayer[Number][even]
[preset=lefttop,voffset=45mm,hoffset=25mm]
{\offset[location=tl,leftoffset=-3mm]
{\tlap{\color[darkgreen]{\scale[height=30mm,width=22mm]{\ss#1}}}}}}
\setupbackgrounds[page][background=Number]
\starttext
\dorecurse{4}{\myNumber{#1}\input knuth \page}
\dorecurse{4}{\myNumber{#1}\dorecurse{6}{\input knuth }\page}
\dorecurse{4}{\myNumber{#1}\dorecurse{3}{\input knuth }\page}
\stoptext

Thanks Wolfgang!
Somehow I overlooked the two subtleties you are teaching me here:
> \definelayer[Number][width=\paperwidth,height=\paperheight,doublesided=yes]
in which the option doublesided=yes, helps and the options [odd] or [even] in \setlayer:
> \setlayer[Number][odd]
> \setlayer[Number][even]
I will wikify this later this weekend.
Best regards: OK
