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 ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 6+ messages in thread

See > http://archive.contextgarden.net/thread/20061102.171506.2fa793e2.en.html 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: \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 ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 6+ messages in thread

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. -- 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 ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 6+ messages in thread
