blank[\lineheight] works with LMTX, fails with MkIV
by Rik Kabel 21 Dec '19

21 Dec '19

MkIV fails with tex error > tex error on line 3 in file c://Users/micro/Desktop/fail.tex: ! Missing \endcsname inserted given the following mwe: \starttext a \blank[\lineheight] z \stoptext Not critical as there are lots of ways to do this, but it seems strange that it should work in one and not the other. -- Rik

by mf 20 Dec '19

20 Dec '19

Hello list, \setuplayout[marking=on] typesets crop marks that are in grayscale black. Can I change their color, in particular into a CMYK black (0,0,0,1.0)? Thanks, Massi

Transparency in PNGs becomes black in PDF/X
by Henning Hraban Ramm 20 Dec '19

20 Dec '19

I think this is the same problem that I had in Bassenge: The transparent part of PNGs like the attached one becomes black if I try to make an PDF/X. I hope that is solvable... \setupbackend[format=PDF/X-1a:2001] \starttext \externalfigure[kinder/esel_kl] \stoptext Best, Hraban

Layer presets / size of type area
by Henning Hraban Ramm 20 Dec '19

20 Dec '19

Hi, I setup a layer to the size of the typearea and expect the corner presets to place my figures into the corners, but \makeupwidth/height are smaller than the typearea (same with \textwidth). Why? Hraban \setuplayout[ width=120mm, backspace=16mm, height=192mm, topspace=6mm, header=8mm, footer=6mm, ] \showframe \definelayer [TA] [x=16mm, y=14mm, width=\makeupwidth, height=\makeupheight] \setupbackgrounds[page][background=TA] \def\Square{\framed[width=1cm,height=1cm]{S}} \starttext \strut \setlayer[TA][preset=leftbottom]{\Square} \setlayer[TA][preset=rightbottom]{\Square} \setlayer[TA][preset=lefttop]{\Square} \setlayer[TA][preset=righttop]{\Square} \stoptext

Style for captions
by Otared Kavian 18 Dec '19

18 Dec '19

Hi all, In the example below, I would like to have the style of the figure's caption to be \itx, but the inline formula is set with a larger body font: is it possible to setup the caption of a float so that a smaller size applies also to the math formula? Best regards: Otared PS: here is the example (not so minimal, sorry…) % begin example-caption.tex \setupcaption[figure][ headstyle={\bix}, style={\itx}] \starttext \startluacode function weierstrass(n,x) local S = 0 for k = 0, n do S = S + 2^(-k)*math.cos(3^k*x) end return S end \stopluacode \startplacefigure[title={The Weierstrass function $\sum_{k=0}^n 2^{-k}\cos(3^kx)$}] \startMPcode{doublefun} draw lmt_function [ xmin = 0, xmax = 4*355/113, xstep =.001, ymin = -2, ymax = 2, sx = 1mm, xsmall = 80, xlarge = 20, sy = 4mm, ysmall = 40, ylarge = 4, xlabels = "yes", ylabels = "yes", linewidth = .015mm, offset = .1mm, code = "weierstrass(5,x)", frame = "sticks", xcaption = "$n = 5$", functions = { [ drawcolor = "darkred", ] } ] xsized .5TextWidth ; \stopMPcode \stopplacefigure \stoptext % begin example-caption.tex

Re: [NTG-context] Moving horizontally a whole ensemble of layers in the same run?

Think of a photo album. To make it interesting the pages should all be different. To this purpose layers are a good means. I'd like to centre the layers on their page without doing so manually and without changig the distances between them. Using luacode one can calculate the distance d between the leftmost and the rightmost edge. Half the difference (\textwidth - d) is the amount to move the whole layer ensemble. My question is now: Does in context exist a possibility to move all layers jointly without correcting all their x-values subsequently? I append the pdf-file of my MWE.
