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: \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. -- 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 ___________________________________________________________________________________
