layers in empty pages
by Pablo Rodríguez 08 Oct '13

08 Oct '13

Dear list, I have the following sample: \setuppagenumbering[alternative=doublesided] \definelayer[MyLayer][state=continue] \setlayer[MyLayer]{This is my layer.} \setupbackgrounds[page][background={MyLayer}] \starttext \input knuth \stoptext I need the text to be double-sided, but is there no way that the layer doesn’t show up when the text area is empty? Many thanks for your help, Pablo -- http://www.ousia.tk

wrong positioning of MP graphic in layer
by Pablo Rodríguez 08 Oct '13

08 Oct '13

Dear list, I have the following sample: \definelayer[wrongpositioned][x=0mm, y=0mm, hoffset=0mm, voffset=48mm, state=start] \setuplayer[wrongpositioned]{\startMPcode draw (0mm,0mm)--(8mm,0mm)--(8mm,38mm)--(14mm,38mm) ; \stopMPcode} \setupbackgrounds[page][background={wrongpositioned}] \starttext \input knuth \stoptext No matter what x, y, hoffset, voffset, location or corner, the MP graphic is located where the page margins start. Sorry for the so basic question, but what is wrong there? Besides that, I don’t understand how positioning in layers work. I have read the wiki, but I don’t get it (geometry isn’t my strength). x, y, hoffset and voffset are fine. But location and corner are mysterious to me. Changing them gave me no clue of what they are. The four mentioned options set a point in the paper. The corner could be the point of the graphic or text that would be set in the previously defined point in the paper. Well, if this isn’t wrong, what can location be? Sorry, I know it‘s my lack of geometrical knowledge. Could anyone be so kind to explain me what location and corner mean in layers? Many thanks for your help, Pablo -- http://www.ousia.tk

Question related to the placement of figures
by Flavien Lambert 08 Oct '13

08 Oct '13

Dear all, I would like to wrap text around two figures. I tried to use both placefigure and starthangaround without achieving what I wanted. So I moved towards you to get some explanations on the behavior of the commands. I have two figures and one paragraph. If possible, I would like to place one figure on the top left and the other on the bottom right, the text moving smoothly in between, something like (o is figure, x text) ooooo xxxxxxxx ooooo xxxxxxxx xxxxxxxxxxxxxx xxxxxxxxxxxxxx xxxxxxxxxxxxxx xxxxxxxx ooooo xxxxxxxx ooooo or even better xxxxxxxxxxxxxx ooooo xxxxxxxx ooooo xxxxxxxx xxxxxxxxxxxxxx xxxxxxxxxxxxxx xxxxxxxxxxxxxx xxxxxxxx ooooo xxxxxxxx ooooo xxxxxxxxxxxxxx xxxxxxxxxxxxxx I can, of course, slice the text in two pieces and use either placefigure or hangaround but, then, there's a vertical space between the two paragraphs. Related to the subject, is there way to impose a few lines before a figure with hangaround like the second layout example? Thanks a lot, Flavien.

Hooking stoptext
by Procházka Lukáš Ing. - Pontex s. r. o. 08 Oct '13

08 Oct '13

Hello, I'm trying to hook commands.stoptext()... Here's a minimal example: why only the first image appears? ---- \startluacode local cmd_p local tab = {} f = function(a) if not cmd_p then cmd_p = commands.stoptext commands.stoptext = function(...) context("Hook") for _, v in ipairs(tab) do context.startTEXpage() context.externalfigure{v} context.stopTEXpage() end cmd_p(...) end end table.insert(tab, a) end \stopluacode \starttext A \ctxlua{f("cow")} \ctxlua{f("hacker")} \stoptext ---- When I modify the code: ---- ... for _, v in ipairs(tab) do --context.startTEXpage() context.externalfigure{v} --context.stopTEXpage() end ... ---- all figures are shown OK. Where's the problem? TIA. Best regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

Re: [NTG-context] Breaks in TOC
by "H. Özoguz" 07 Oct '13

07 Oct '13

> http://www.ntg.nl/pipermail/ntg-context/2013/072485.html > > Wolfgang Thanks Wolfgang, so I guess the key I was looking for is "list". But see what happens here: \starttext \completecontent \startsection[ title={Eine sehr, sehr lange Überschrift, die auf jeden Fall irgendeine Art von Formatierung benötigt.}, list={Eine sehr, sehr lange Überschrift,\\die auf jeden Fall irgendeine Art von Formatierung benötigt.} ] \startsection[ title={Eine sehr, sehr lange Überschrift, die auf jeden Fall irgendeine Art von Formatierung benötigt.}, list={Eine sehr, sehr lange Überschrift,\par die auf jeden Fall irgendeine Art von Formatierung benötigt.} ] \stoptext The first try with "\\" has no effect. And the second with "\par" justifies the first line, which is not intended. How to get only a normal break, without new aligning of the first line? Huseyin

Hi, I played around with the new passvariable() option and ran into errors when passing a path. Used the latest beta (01.10.2013). Can someone confirm this? Peter
