Disappearing font feature
by Rik Kabel 22 Dec '19

22 Dec '19

List, I have a strange case of a font feature disappearing when many fonts are used. In creating a sampler for the Jost* font (free at https://indestructibletype.com/Jost.html) and using its feature ss01 to get single-storey lower-case a, the font reverts to the default two-storey a when many weights are shown. When I create the fonts with \definefontfamily, the upright weights are fine and the italic weights revert. When I create the fonts with \definefont, the reverse is the case. Below is the demonstration for the \definefont variation and a snip of the failing result. \definebodyfontenvironment[13pt] [interlinespace=15pt] \setuplayout [backspace=0pt, topspace=30pt, width=middle, height=middle, location=middle, header=0pt, footer=0pt] \setuppagenumbering [location=] \definefontfeature [default] [default] [ss01=yes] \definefont [JHair] [jost-100-hairline] \definefont [JThin] [jost-200-thin] \definefont [JLigh] [jost-300-light] \definefont [JBook] [jost-400-book] \definefont [JMedi] [jost-500-medium] \definefont [JSemi] [jost-600-semi] \definefont [JBold] [jost-700-bold] \definefont [JHeav] [jost-800-heavy] \definefont [JBlac] [jost-900-black] \definefont [JHairI][jost-100-hairlineitalic] \definefont [JThinI][jost-200-thinitalic] \definefont [JLighI][jost-300-lightitalic] \definefont [JBookI][jost-400-bookitalic] \definefont [JMediI][jost-500-mediumitalic] \definefont [JSemiI][jost-600-semiitalic] \definefont [JBoldI][jost-700-bolditalic] \definefont [JHeavI][jost-800-heavyitalic] \definefont [JBlacI][jost-900-blackitalic] \startbuffer [Sampler] A B C D E F G H I J K L M N O P Q R S T U V W X Y Z a b c d e f g h i j k l m n o p q r s t u v w x y z à ë í ô ç 1 2 3 4 5 6 7 8 9 0 ` \texttilde\ - = ! @ \# \$ \letterpercent\ ^ \& * ( ) _ + [ ] \textbackslash\ ; ' , . / \{ \} \| : " < > ? \fontname\font \blank [line] \stopbuffer \setupalign [middle] \starttext \obeylines \JHair \getbuffer[Sampler] \JThin \getbuffer[Sampler] \JLigh \getbuffer[Sampler] \JBook \getbuffer[Sampler] \JMedi \getbuffer[Sampler] \JSemi \getbuffer[Sampler] \JBold \getbuffer[Sampler] \JHeav \getbuffer[Sampler] \JBlac \getbuffer[Sampler] \page \JHairI \getbuffer[Sampler] \JThinI \getbuffer[Sampler] \JLighI \getbuffer[Sampler] \JBookI \getbuffer[Sampler] \JMediI \getbuffer[Sampler] \JSemiI \getbuffer[Sampler] \JBoldI \getbuffer[Sampler] \JHeavI \getbuffer[Sampler] \JBlacI \getbuffer[Sampler] \stoptext Below is the demonstration for the \definefontfamily variation and a snip of the expected result, although the italics fail. \definebodyfontenvironment[13pt] [interlinespace=15pt] \setuplayout [backspace=0pt, topspace=15pt, width=middle, height=middle, location=middle, header=0pt, footer=0pt] \setuppagenumbering [location=] \definefontfeature [default] [default] [ss01=yes] \definefontfamily [up-one] [sansserif] [Jost] [tf={style:hairline,features}, bf={style:thin,features}, bi={style:light,features}, it={style:book,features}] \definefontfamily [up-two] [sansserif] [Jost] [tf={style:medium,features}, bf={style:semi,features}, bi={style:bold,features}, it={style:heavy,features}] \definefontfamily [up-three] [sansserif] [Jost] [tf={style:black,features}, bf={style:black,features}, bi={style:black,features}, it={style:black,features}] \definefontfamily [it-one] [sansserif] [Jost] [tf={style:hairlineitalic,features}, bf={style:thinitalic,features}, bi={style:lightitalic,features}, it={style:bookitalic,features}] \definefontfamily [it-two] [sansserif] [Jost] [tf={style:mediumitalic,features}, bf={style:semiitalic,features}, bi={style:bolditalic,features}, it={style:heavyitalic,features}] \definefontfamily [it-three] [sansserif] [Jost] [tf={style:blackitalic,features}, bf={style:blackitalic,features}, bi={style:blackitalic,features}, it={style:blackitalic,features}] \startbuffer [Sampler] A B C D E F G H I J K L M N O P Q R S T U V W X Y Z a b c d e f g h i j k l m n o p q r s t u v w x y z à ë í ô ç 1 2 3 4 5 6 7 8 9 0 ` \texttilde\ - = ! @ \# \$ \letterpercent\ ^ \& * ( ) _ + [ ] \textbackslash\ ; ' , . / \{ \} \| : " < > ? \fontname\font \blank [line] \stopbuffer \setupalign [middle] \setupbodyfont [up-one,13pt] \starttext \obeylines \ss\tf\getbuffer [Sampler] \ss\bf\getbuffer [Sampler] \ss\bi\getbuffer [Sampler] \ss\it\getbuffer [Sampler] \switchtobodyfont [up-two] \ss\tf\getbuffer [Sampler] \ss\bf\getbuffer [Sampler] \ss\bi\getbuffer [Sampler] \ss\it\getbuffer [Sampler] \switchtobodyfont [up-three] \ss\tf\getbuffer [Sampler] \page \switchtobodyfont [it-one] \ss\tf\getbuffer [Sampler] \ss\bf\getbuffer [Sampler] \ss\bi\getbuffer [Sampler] \switchtobodyfont [it-two] \ss\tf\getbuffer [Sampler] \ss\bf\getbuffer [Sampler] \ss\bi\getbuffer [Sampler] \ss\it\getbuffer [Sampler] \switchtobodyfont [it-three] \ss\tf\getbuffer [Sampler] \stoptext Assistance or explanation is welcome.

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

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
