Predefined output intents:
by jbf 16 Jun '25

16 Jun '25

I know I have raised this before, but I continue to be confused. I spoke with our printer dept and they told me I need to use Coated FOGRA39 (ISO 12647-2:2004) as intent. 1. I checked the wiki and it tells me that Predefined output intents includes the above intent. But my log file tells me: backend > profiles > profile specification 'Coated FOGRA39' not found in 'colorprofiles.xml, colorprofiles.lua'. (I am using ConTeXt ver: 2022.08.25) 2. I checked on the internet re colorprofile files and it tells me that I can download Coated_Fogra39L_VIGC_300.icc as an icc version that is commonly used by Adobe and I feel sure it would be sufficient for my printer's purposes. I placed it where the other profile files are located in the ConTeXt tree /context/tex/texmf-context/colors/icc/profiles 3. It is still not recognised, but perhaps I have to run a command for that to happen. My question(s): - is my procedure correct? In other words, can I place such a file in the profiles subfolder and expect it to work? - do I need to run a particular context -- command for this to happen? Julian

upload
by Hans Hagen 16 Jun '25

16 Jun '25

Hi, I uploaded a new version, this time a bit of beta, because of: -- reworked control over callbacks: more restrictive, some protection against overload, better control; as a side effect context can run a bit faster but it depends on the job and features used; if something is not working as expected it might relate to this (easy to fix) -- some preparations for an upgrade of grid snapping, profiling and spacing (mostly related to math in the new columnsets); we're still working on columnsets (side effect of mikael converting some advanced documents to use it) -- overload protection enabled, for the moment only the warnings but at some point we might become more restrictive; keep an eye on messages so that you can see where your styles actually messes with already defined macros or enter the dangerous zone of changing primitives; fwiw: i've been running the highest level of protection already for years now (error mode) .. you can try \enabledirectives [overloadmode=error] at the top of your file to see how badly you behave -- a few fixes here and there (related to mailing list questions and reports); nothing spectacular -- some preparations wrt the new signalling mechanism(s) ... more about that after the meeting -- additional warnings (or abort) in case one runs from tex live and missing or expected files -- we're playing with some potential speedups but given the litle gain they might not make it into the lot eventually (if you run into bottlenecks, lets me know, with examples) if there are unexpected side effects, let me know and i'll fix and upload again Hans ps. i might reintroduce the beta/current updating scheme at some point .. still undecided ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Diacritic in variable fonts
by paper＠mgrz.de 15 Jun '25

15 Jun '25

Hi, I really like the idea of using a single font and only changing variables and using it for the whole document. Ubuntu Sans (Variable) makes this possible, but upper diacritics (eg. Ä) are not scaled when width is changed, the lower diacritics (eg. ą) seem to work as desired. Unfortunately, I can't narrow down the problem any further. I can change the width with Google Fonts without any errors, and Inkscape doesn't cause any problems either. How can I fix that? Thanks for support mwe : Context Version; 2025.06.12 14:21 \definefontfeature [fntubuntf] [axis={wght=300,wdth=75}] \definefontfamily [ubuntufont] [ss] [Ubuntu] [tf={file:{UbuntuSans[wdth,wght].ttf},features:fntubuntf,}] \setupbodyfont [ubuntufont, ss] \starttext ÄöÖöÜü \stoptext

Can Bytemaps be overwritten?
by Keith McKay 15 Jun '25

15 Jun '25

Hi all, I've been doing some testing to see if bytemaps can be overwritten as a way of reusing them and came up with the code below. The MPpage page 1 should, if my thinking is correct, give three unitsquares coloured red, blue, and green. However it seems the squares are all coloured green. To get what I expected I rewrote the code as in MPpage page 2, but to get the desired outcome I had to create 3 bytemaps. So, does this mean that bytemaps can't be overwritten, or am I missing something? Best Wishes Keith \starttext \startMPpage %page 1 color newColor; newbytemap 1 of (250,250,3); p := 0; for i = 1 upto 3: for x := 0 upto 249: for y := 0 upto 249: if i = 1: newColor := \MPcolor{red}; elseif i = 2: newColor := \MPcolor{blue}; else: newColor := \MPcolor{green}; fi; setbyte (x,y) of 1 to (newColor * 255); endfor; endfor; p := p + 259; fill unitsquare scaled 250 shifted(p - 259,0) withbytemap 1; endfor; \stopMPpage \startMPpage%page 2 color newColor; p := 0; for i = 1 upto 3: newbytemap i of (250,250,3); for x := 0 upto 249: for y := 0 upto 249: if i = 1: newColor := \MPcolor{red}; elseif i = 2: newColor := \MPcolor{blue}; else: newColor := \MPcolor{green}; fi; setbyte (x,y) of i to (newColor * 255); endfor; endfor; p := p + 259; fill unitsquare scaled 250 shifted(p - 259,0) withbytemap i; endfor; \stopMPpage \stoptext

Opening quotation mark
by John Was 15 Jun '25

15 Jun '25

Hello I have found that trep=yes gives me correct closing quotation marks in the commercial font Baskerville MT Pro if I type the simple ' as usual in TeX; but opening quotation marks remain as ` or ``. In XeTeX I could get round this with e.g.: \catcode"0060=\active% 0060 is the position for ` \def`{{\char"2018}}% 2018 is the position for ‘ (opening quote) But this fails in ConTexT. Any idea how to fix this, with or without any \catcode fiddling? (In XeTeX the font works as expected if I just give mapping=tex-text when setting up the font call, but I don't see an obvious version of that in ConTexT.)

Alternate text for figures that includes math
by Matthias Weber 15 Jun '25

15 Jun '25

Dear All, When tagging an image, it looks like the provided alternative text is used verbatim. That means no TeX commands are interpreted, nor any math is being interpreted. Is it possible to serialize the math in an alternate text (as the tracker does with the non-ALT math in the example below)? I can do this manually, but my figures contain quite a bit of math, and it would be nice if alternate text for math is provided consistently throughout the document. Thanks, Matthias \usemodule[mathml] \enabledirectives [backend.usetags=testing] \setuptagging[state=start] \setupstructure[state=start] \setupbackend [format=PDF/A-3a] \setupbackend[format=pdf/ua-1] \setupexternalfigures[location=default] \setupnote[mathnote][location=page] \enabletrackers[math.textblobs] \starttext \placefigure [here] [] % label {} % legend {\externalfigure[cow][label={A cow, contemplating $e^{\pi i}+1=0$}]} % path A human, contemplating $e^{\pi i}+1=0$. \stoptext

New user here!

Good day, Contexters I've been using plain TeX for many years (EmTeX, if anyone can remember that, and latterly XeTeX), but my motivation for getting acquainted with ConText, rather late in life, is the need to produce tagged PDFs that will be accessible to the visually impaired (generally using an audio reader), and I understand (or at least hope) that ConText can help with that. I'm only just getting started with the *Not so Short Introduction*, and of course have many questions which I think/hope I will be able to answer myself from the documentation: I've not managed to load pstricks or edmac, for example, but this must be possible, and some primitives such as \baselineskip seem to have disappeared, together with the font-call system I'm used to: \font\umirtenpointsevenfive = "MinionPro-Regular:+onum:mapping=tex-text:letterspace=1.6" at 10.75pt All that will come as I read the instructions, but what I'm most interested to achieve is tagging that will not only produce the usual column of bookmarks at the left-hand side but will also allow an audio reader to read such things as alt-text for illustrations and, crucially, read a heavily footnoted text in the correct order. For this I take it that the footnotes will have to be tagged in a special way, allowing visually impaired readers either to suppress them as the text is read out, or else to include them at the point where the cue occurs, then revert back to the main text. With my XeTeX-produced PDFs an audio reader will simply read all of the main text on a page, then the footnotes (the last of which may be split between pages), and then start again on the next page - clearly annoying and unacceptable to those who can't see the PDF. I'd be most grateful to be pointed in the right direction - or is what I've outlined simply not achievable?

line breaks within *section title
by damien＠thiriet.web4me.fr 14 Jun '25

Hi, My presentations are using the luciole font (https://luciole-vision.com/) a font designed for eyed-impaired people and big sizes. It is quite appreciated by my pupils. However, some titles are overboxed. There is certainly a way to force line break and avoid such breaks, but I don't know it (although I attended Hans and Mikael's brilliant speeches about \penalty ). I designed a MWE reproducing this with Latin Modern Sans. \setuppapersize [S3] \setupbodyfont [sans,24pt] \setupalign[nothyphenated] \setuptolerance[verytolerant,stretch] \starttext \startsection[title={Don't be hyphenated, no overfullboxes}] \input ward \stopsection \stoptext Thanks, Damien PS: For those interested in Luciole, my typescripts: %\starttypescript [luciole] % \definefontsynonym [Luciole-Regular] [file:Luciole-Regular] % \definefontsynonym [Luciole-Italic] [file:Luciole-Regular-Italic] % \definefontsynonym [Luciole-BoldItalic] [file:Luciole-Bold-Italic] % \definefontsynonym [Luciole-Bold] [file:Luciole-Bold] %\stoptypescript % %\starttypescript [luciole] % \setups [font:fallback:sans] % \definefontsynonym[Sans] [Luciole-Regular] [features=default] % \definefontsynonym[SansItalic] [Luciole-Italic] [features=default] % \definefontsynonym[SansBoldItalic] [Luciole-BoldItalic] [features=default] % \definefontsynonym[SansBold] [Luciole-Bold] [features=default] %\stoptypescript % %\starttypescript [luciole] % \definetypeface [luciole] [ss] [sans] [luciole] [default] %\stoptypescript % %\usetypescriptfile [luciole] %\setupbodyfont[luciole,sans,24pt]
