Color Profiles in lmtx
by juh 13 Feb '20

13 Feb '20

Hi all, again I have a question concerning color profiles. I have this to load the ISO Coated v2 300% profile. \setupbackend[ format=PDF/X-3:2003, intent={ISO Coated v2 300\letterpercent\space (ECI)}, ] \setupcolors[cmyk=yes,rgb=no,] But is this profile part of the new lmtx version? I get this in my logs backend > profiles > profile specification 'ISO Coated v2 300% (ECI)' loaded from '/home/juh/context-linux-64/tex/texmf-context/colors/icc/context/colorprofiles.xml' But I am not sure whether the profile is really loaded. In the old context distribution I had to put the profile in texmf-local. There is this in lmtx: ~/context-linux-64/tex/texmf-context/colors/icc/profiles$ ls -l insgesamt 3652 -rw-r--r-- 1 juh juh 416 Jan 6 16:32 default_gray.icc -rw-r--r-- 1 juh juh 1992 Jan 6 16:32 ecirgb_v2.icc -rw-r--r-- 1 juh juh 700 Jan 6 16:32 ecirgb_v2_iccv4.icc -rw-r--r-- 1 juh juh 1829093 Jan 6 16:32 isocoated_v2_300_eci.icc -rw-r--r-- 1 juh juh 1829077 Jan 6 16:32 isocoated_v2_eci.icc -rw-r--r-- 1 juh juh 3144 Jan 6 16:32 srgb.icc -rw-r--r-- 1 juh juh 60960 Jan 6 16:32 srgb_v4_icc_preference.icc I am not sure if the file name matches as in profiles.xml we have this with mixed upper and lower cases: <profile> <filename>ISOcoated_v2_300_eci.icc</filename> <colorspace>CMYK</colorspace> <class>prtr</class> <id>FOGRA39</id> <info>ISO Coated v2 300% (ECI)</info> <checksum>e14f5db955711d914d877df35ad7a1b5</checksum> <version>24000000</version> <url>http://www.color.org</url> <outputcondition>Offset printing, according to ISO 12647-2:2004/Amd 1, OFCOM, paper type 1 or 2 = coated art, 115 g/m2, tone value increase curves A (CMY) and B (K)</outputcondition> </profile> Is there a linux tool to test if the correct profile is part of the pdf? Any hints?

mtxrun
by Rudolf Bahr 12 Feb '20

12 Feb '20

Hello ConTeXters! LuaMetaTeX, Version 2.03.15 ConTeXt ver: 2020.02.07 18:36 MKIV beta fmt: 2020.2.10 works well doing my usual tasks. Now, I put an .otf-font into ".../tex/texmf-local/", and made mtxrun --generate mtxrun --script fonts --reload mtxrun --script fonts --list --all --pattern=<pattern*>, but didn't get the expected information on the new font from the last command. So I investigated the output of the first two commands in more detail and found: 1. mtxrun --generate: resolvers | resolving | warning: no lua configuration files found resolvers | resolving | no texmf paths are defined (using TEXMF) By the way, "TEXMF" seems to be a mtxrun variable and hasn't directly to do with the environmental variable "TEXMF" which gets extinguished. 2. mtxrun --script fonts --reload: mtxrun | the resolver databases are not present or outdated mtxrun | unknown script 'fonts.lua' or 'mtx-fonts.lua' Please, what is to be done? Best wishes, Rudolf

macro that does not work (Metapost)

Hi, I have some problems with the following macro : tex error > mp error on line 23 in file /home/viserion/macro.tex: ! Missing argument to suite. <to be read again> { <*> suite{ 1,0}; suite(2,1); ; That macro has more parameters than you thought. I'll continue by pretending that each missing argument is either zero or null. ! Missing argument to suite. <to be read again> { <*> suite{ 1,0}; suite(2,1); ; That macro has more parameters than you thought. I'll continue by pretending that each missing argument is either zero or null. ! Extra tokens will be flushed. <to be read again> { <*> suite{ 1,0}; suite(2,1); ; I've just read as much of that statement as I could fathom, so a semicolon should have been next. It's very puzzling... but I'll try to get myself back together, by ignoring everything up to the next `;'. Please insert a semicolon now in front of anything that you don't want me to delete.

MWE: \starttext The famous result (and again) is given by \placeformula[formulalabel] \startformula c^2 = a^2 + b^2. \stopformula And now we can refer to formula \ref[][formulalabel]. \stoptext There is a blank where the formula label should be at “now we can refer to formula ---“. Regards Jon

Side effects with \startformula \stopformula

Hi, I composed a large document and I often use \ startformula \ stopformula. I have the impression that this creates untimely page breaks or white spaces. Fabrice

issues with \attachment when specifying name
by Pablo Rodriguez 08 Feb '20

08 Feb '20

Hi Peter, here you have a minimal sample with file name changed inside the attachment command: \setupinteraction[state=start] \starttext an attachment\attachment[file=secret-name.pdf, type={application/pdf}, %~ method=hidden, name=other-name] \stoptext If method is hidden (no annotation), /EmbeddedFiles doesn’t honor the "name" option. If method is normal (generating an annotation), /T in /FileAttachment doesn’t "honor the "name" option. Would it be possible that both cases contain the value from the name "option" instead of file? Many thanks for checking this, Pablo -- http://www.ousia.tk

Fonts from various .otf to work with \bold, \emph, \bf, \bfa ...
by context＠vivaldi.net 08 Feb '20

08 Feb '20

Hello, although font switching used to be discussed here and I studied wiki about font changing, I don't switch fonts in ConTeXt very often and my "maximum" font change was provided by \setupbodyfont[(e.g. termes)]. Now I am in the situation that I need to use fonts defined in: work-sans.bold.otf work-sans.bold-italic.otf work-sans.light.otf work-sans.light-italic.otf (all from https://www.1001fonts.com/work-sans-font.html) so that: - normal text and math (nothing special - just subscripts) would be typeset with work-sans.light.otf - \bold (\bf) would use work-sans.bold.otf, - \emph (\em and \it) would use work-sans.light-italic.otf, - \bi would use work-sans.bold-italic.otf - also commands \bfa, \bfc, ... would use work-sans.bold.otf scaled somehow (probably by multiples of 1.2). Some help setting it up and making it work would be appreciated... Best regards, Lukas

suggestions for \definefontfamily and \definefallbackfamily
by Pablo Rodriguez 07 Feb '20

07 Feb '20

Hi Wolfgang, would it be possible that \definefontfamily could load fonts directly (not defined in the font database), like \definefont? \definefont[Test][file:texgyrepagella-regular.otf at 10pt] \definefont[TestOne][file:texgyrepagella-regular-500.otf at 10pt] \definefontfamily [mainface] [rm] [Pagella] [tf={file:texgyrepagella-regular.otf}, bf={file:texgyrepagella-regular-500.otf}] \setupbodyfont[mainface] \starttext normal\\ \bf bold not working\\ \Test this works \TestOne this works \stoptext The second improvement would be to allow "method=uppercase" with \definefallbackfamily to be able to fake smallcaps (as used with \definefontfallback in https://mailman.ntg.nl/pipermail/ntg-context/2018/092878.html) Many thanks for your help, Pablo -- http://www.ousia.tk

[HOWTO] spanning xtable cells

Does anyone knows a hint to get the stacked boxes to the correct size? When usinig non-zero values for the options spaceinbetween and/or columndistance the cells of the xtable will not properly size when spanning over rows and/or columns. e.g. \starttext \startxtable[spaceinbetween=2mm, columndistance=2mm, corner=round] \startxtablebody \startxrow \startxcell[ny=3] a1 \stopxcell \startxcell[nx=2] a2/3 \stopxcell \startxcell[ny=3] a4 \stopxcell \stopxrow \startxrow \startxcell b2 \stopxcell \startxcell b3 \stopxcell \stopxrow \startxrow \startxcell c2 \stopxcell \startxcell c3 \stopxcell \stopxrow \startxrow \startxcell[nx=3] d1/2/3 \stopxcell \startxcell d4 \stopxcell \stopxrow \startxrow \startxcell e1 \stopxcell \startxcell e2 \stopxcell \startxcell e3 \stopxcell \startxcell e4 \stopxcell \stopxrow \stopxtablebody \stopxtable \stoptext
