Hello all, I'm learning a little bit of metapost language, using metafun manual. I made some background for a title (surely the code is awful, thanks for suggestions of improvement) but it's static, i'd like to adapt it to the widthof the text. I don't know if it is possible from my code and if it is i don't know how to do ! Thanks for any help, best regards, Roland My code : \setuplayout[width=fit,height=fit,header=0cm,topspace=1.8cm,footer=1.2cm,% bottomspace=1cm,backspace=6cm,leftmargin=1.5cm, leftmargindistance=0.5cm,rightmargin=1cm,rightmargindistance=0.5cm, location=singlesided] \startuniqueMPgraphic{essai} path p,p',q,q'; p:=(0,0.1cm)--(12cm,0.3cm); q:=(11cm,-0.7cm)--(11.5cm,2.2cm); p':=(11.7cm,1.3cm)--(-0.4cm,1.4cm); q':=(0.3cm,2.4cm)--(0.2cm,-0.3cm); draw p withpen pencircle scaled 1mm withcolor 0.3white; draw p' withpen pencircle scaled 1mm withcolor 0.3white; draw q withpen pencircle scaled 1mm withcolor 0.3white; draw q' withpen pencircle scaled 1mm withcolor 0.3white; pair A; A:=q'intersectionpoint p'; pair B; B:=q intersectionpoint p'; pair C; C:=p intersectionpoint q; pair D; D:=q'intersectionpoint p; path s; s:= A--B--C--D--cycle; fill s withcolor .8white; \stopuniqueMPgraphic \starttext \defineoverlay[encadrement][\uniqueMPgraphic{essai}] \framed[frame=off,background=encadrement]{\it\tfb\color[darkred]{Devoir de mathématiques}} \stoptext

recalculate background on every page with \uniqueMPgraphic?
by Mikael P. Sundqvist 04 Mar '13

04 Mar '13

Dear list, with the (almost minimal) example below, I hoped that the frame would be recalculated at every page. But it is not (they all look the same in my output pdf). How can I force the frame to be redrawn at every page? Btw, If I change the uniqueMPgraphic to useMPgraphic (everywhere) my file does not compile anymore. I get some lua error. /Mikael \setuppapersize[S6][S6] \setuplayout[ width=fit, height=fit, margin=1pt, topspace=0.5cm, headerdistance=0.3cm, footerdistance=0.5cm, footer=14pt, backspace=1.5cm, location=middle, ] \startuniqueMPgraphic{figram} path q; rr:=7mm; StartPage; q := lrcorner Field[RightMargin][Header] -- llcorner Field[LeftMargin][Header] -- ulcorner Field[LeftMargin][Footer] -- urcorner Field[RightMargin][Footer] -- cycle; draw q withcolor 0.7white; draw (urcorner q)--((urcorner q) xshifted 1bp+(uniformdeviate rr)) withcolor .7white; draw (urcorner q)--((urcorner q) yshifted 1bp+(uniformdeviate rr)) withcolor .7white; draw (ulcorner q)--((ulcorner q) xshifted -1bp-(uniformdeviate rr)) withcolor .7white; draw (ulcorner q)--((ulcorner q) yshifted 1bp+(uniformdeviate rr)) withcolor .7white; draw (llcorner q)--((llcorner q) xshifted -1bp-(uniformdeviate rr)) withcolor .7white; draw (llcorner q)--((llcorner q) yshifted -1bp-(uniformdeviate rr)) withcolor .7white; draw (lrcorner q)--((lrcorner q) xshifted 1bp+(uniformdeviate rr)) withcolor .7white; draw (lrcorner q)--((lrcorner q) yshifted -1bp-(uniformdeviate rr)) withcolor .7white; StopPage; \stopuniqueMPgraphic \defineoverlay[figram][\uniqueMPgraphic{figram}] \setupbackgrounds[page][background=figram] \starttext \dorecurse{10}{\input knuth} \stoptext

FiXme and ConTeXt mkiv
by Janne Junnila 04 Mar '13

04 Mar '13

Hi all, I was trying to use the FiXme module today, but it seems like it is using some macros that are only available in mkii. Does anyone know of any alternatives? (Or is anyone planning on porting FiXme to mkiv?) Thanks, Janne Junnila

About Chapter head definition and FunnyFrame
by Jeong Dalyoung 03 Mar '13

03 Mar '13

Dear all, I have two questions. 1. I defined \Myheader and use it to shape the chapter head as following: \def\Myheader#1#2{% \framedtext [width=\overlaywidth, height=9\bodyfontsize, background=color, backgroundcolor=lightgray, offset=2pt, strut=no, frame=off, align={middle, middle}] { {\tfb 제 #1 장} \blank[big] {\sans #2} }} \startsectionblockenvironment[bodypart] \setupheadertexts[][{\tfx COUNTING}] \setuppagenumber[number=1] \setuppagenumbering[alternative={singlesided,doublesided},location={footer,right}] \setuphead[chapter][command=\Myheader,before={\dontleavehmode\blank[2*big]},after={\blank[5*big]}, page=right] \stopsectionblockenvironment …. \chapter{The Addition Principle \crlf {\tfx Sum Rule}} …. But it produces an error which is … ! Argument of \Myheader has an extra }. system > tex > error on line 94 in file SumRule.tex … What is wrong in this code? 2. I used "funnyFrame" defined in the MetaFun book. It works fine except that it is left aligned. I'd like to put such a frame in the middle. But \startalignment[middle] didn't work. Is there any way to make FunnyFrame center aligned? Thank you for the reading. Best regards, Dalyoung

A trouble with setupbodyfontenvironment
by Alasdair McAndrew 01 Mar '13

01 Mar '13

So I've come back to using ConTeXt after a year away from it (publishers preferring LaTeX, y'know), and in revising some student notes I'm getting errors which seem new. For a collection of overheads, I've set up \setupbodyfontenvironment[default][em={\slanted\color[red]}] However, when I run context on my files, a command such as {\em elephant} produces: l.3 The {\em elephant} is a large gray animal ? h The control sequence marked <to be read again> should not appear between \csname and \endcsname. What's going on here, and how do I fix it? Thanks, Alasdair

vertical position in itemize and math
by Mikael P. Sundqvist 01 Mar '13

01 Mar '13

Hi, I have two problems with vertical position, one in itemize and one in math. The example below show them both. \starttext \startitemize[n] \item \startitemize[a][left={},right={)},stopper=] \item Bla bla $\theta = \arctan\bigl(\frac{\bar{y}^2}{\bar{x}^2}\bigr)$ % comment this line out to see the problem disappear \stopitemize \stopitemize Let \startformula A=I-2\frac{NN^T}{N^TN}\,N=\frac{1}{9}X. \stopformula \stoptext The first one is the vertical position of the a) and the following formula. This is pushed down (because of the formula it seems). What if I want the a) aligned with the 1.? (I wrote about this problem some time ago, and it got solved, but that time no math was included) The second one is the "division line" in \frac{NN^T}{N^TN} that look pushed down to me. I'm not sure how it should be, but my guess is aligned with the minus sign or so. All this with the latest ConTeXt suite. /Mikael

[***SPAM***] float placement riddle
by Meer, H. van der 01 Mar '13

01 Mar '13

Please can someone explain why the column before the floating figure is empty? I thought that the figure would float through the text to the first location with sufficient space. That appears not te be the case: the input behind the figure does not typeset before it although there is ample space for the text that now follows the picture. The code is roughly: \setupcolumns[n=2] \startcolumns <several paragraphs> \placefigure[][figuur:zw]{Street.} {\externalfigure[zw][width=0.8\textwidth]} \par <small paragraph following picture> <several paragraphs extending to next page> \stopcolumns How to get Hans van der Meer [cid:796264A3-FA21-43EB-894F-3C74D1E4D519@fritz.box]

Arranging framed text without gaps
by Matthias Weber 28 Feb '13

28 Feb '13

Dear all, I am trying to create a table where the entries have determined width and height. They typically are something like \framed[width=5cm,height=4cm,align={center,middle}{Text} and I understand that I will be responsible for making the dimensions so that everything fits nicely. After playing around without much success with the various tables, I came up with the following which is not exactly ConTeXt-like: \setupframed[ width=5cm, height=4cm, location={middle}, align={center,middle} ] \setupbodyfont[24pt] \starttext \hbox{{\framed{Jim}}{\framed{Mary}}{\framed{John}}} \hbox{{\framed{Patsy}}{\framed{Bob}}{\framed{Linda}}} \hbox{{\framed{Mike}}{\framed{Babsy}}{\framed{Bill}}} \hbox{{\framed{Liz}}{\framed{Dave}}{\framed{Jenny}}} \hbox{{\framed{Dick}}{\framed{Sue}}{\framed{Chuck}}} \hbox{{\framed{Maggie}}{\framed{Joe}}{\framed{Dolley}}} \hbox{{\framed{Tom}}{\framed{Lisa}}{\framed{Chris}}} \hbox{{\framed{Nancy}}{\framed{Paul}}{\framed{Betty}}} \stoptext I get small gaps between the horizontal rows which I don't like. Also, in my (possibly not quite up to date) MkIV, the texts isn't centered. In MkII it is. My questions: How do I -- achieve the desired layout (exact dimensions, frames, no gaps) the right way, -- without gaps between horizontal rows -- with text centered in the frames also in MkIV? Thanks a lot - Matthias
