Tent style cards
by Pavneet Arora 22 Dec '19

22 Dec '19

Hello. I am trying to do up some tent style table place holder cards for my daughter's wedding, and have been wracking my brain for a solution for a couple of days now. Having tried many alternatives, this is the closest I have come up with. But mirroring doesn't work. If I use \setuparranging[2*4] mirroring works, but I only need tent style (1*2 head-to-head) so that I can trim to size. Any template that could be suggested would be most helpful as the wedding is on Mon (yikes!). advTHANKSance. >>>MWE<<< \definepapersize[tblcard][width=4in,height=3in] \setuppapersize[tblcard][letter,portrait] \setuparranging[2TOP] \setuplayout[ height=3in, width=4in, topspace=0in, header=0in, bottomspace=0in, footer=0in, backspace=0.0in, %% location=middle, marking=on, ] \startbuffer[tblcard] \strut \tfd A Name \stopbuffer \starttext \showframe \adaptpapersize[tblcard,mirrored][letter,portrait]\getbuffer[tblcard] \page \getbuffer[tblcard] \stoptext -- Pavneet Arora m: +1 647-406-6843 Waroc Informatik e: pavneet_arora(a)waroc.com

How to use together lmt_axis, lmt_grid and lmt_function
by Otared Kavian 22 Dec '19

22 Dec '19

Hi, I am experimenting the new LuaMetaTeX features introduced recently, but I can't get the built-in features together. To explain the problem I encounter, I want to draw the graph of a function on a grid in which the x-axis and the y-axis are alos drawn. Now lmtx has the « instances » (if I am not wrong…) named lmt_axis, lmt_grid and lmt_function which separately work fine, but I dont see how to use them simultaneously by keeping the correct scaling. In the minimal example below, copied from luametafun.pdf, the graph of the function $f(x) := (x - 1)^2$ should be drawn by showing its minimum at $x = 1$, and its value at $x = 0$ should be equal to 1. However the graph on the grid does not show this. Moreover the axes do not match the grid. This means that I have not understood how to give the same units and scales in the three instances lmt_axis, lmt_grid and lmt_function. Thanks for any help: Otared K. PS: here is a minimal example % begin grid-axis-function.tex \starttext \startplacefigure \startMPcode{doublefun} draw lmt_grid [ nx = 10, ny = 10, dx = 1, dy = 1 ] xsized 5cm withpen pencircle scaled .1pt withcolor "darkblue" ; draw lmt_axis [ nx = 10, ny = 10, dx = 1, dy = 1, ] xsized 5cm withpen pencircle scaled .5pt withcolor "darkred" ; draw lmt_function [ xmin = 0, xmax = 2, xstep = .05, ymin = 0, ymax = 1.5, code = "(x - 1)*(x - 1)", ] xsized 5cm withpen pencircle scaled .75pt ; \stopMPcode \stopplacefigure \stoptext % end grid-axis-function.tex

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?

Dear list, I have the following sample: \definefontfamily[emoj][rm][Noto Emoji] \setupbodyfont[emoj] \starttext 🔔💻🔨🔩 \utfchar{0x23f0} \utfchar{0xfe4eb}󾓦󾓧󾓨󾓩󾓪󾓫󾓬󾓭󾓮 \utfchar{0xfe4eb}󾓦󾓧󾓨󾓩󾓪󾓫󾓬󾓭󾓮 \stoptext Is there any way to access glyphs from the private area (0Xfe4eb in the sample) in ConTeXt? I would need to use these glyphs for a presentation I have. Many thanks for your help, Pablo -- http://www.ousia.tk

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
