Hello list, I remember having read something about this, but I can't remember where: I need to prevent the next \par. The context (lowercase) is XML typesetting, where sometimes I want to concatenate two paragraphs in a particular typesetting, while keeping the original structure of the document (two distinct paragraphs). To give you an idea, in XHTML it could be something like this: ----------- <p>This is a paragraph.<?injecttex \preventpar ?></p> <p>This is the next paragraph.</p> ----------- Massi

Alternate text for figures that includes math
by Matthias Weber 20 Jun '25

20 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

Time stamp on PDFs
by John Was 20 Jun '25

20 Jun '25

I have figured out how to place a date stamp on my PDFs (outside of the printable area bounded by crop marks) but I would ideally like to include the time of processing as well. I don't see anything like the plain TeX primitive \time (and when out of curiosity I tried '\the\time' this returned a mysterious number - today it is '691' - which doesn't seem relevant).

Predefined output intents:
by jbf 19 Jun '25

19 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

Diacritic in variable fonts
by paper＠mgrz.de 18 Jun '25

18 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

Using Kurinto: Cursive/Slanted
by Mike Urban 18 Jun '25

18 Jun '25

I continue to be stumped by font stuff. I want to use the cursive-style font (font family Kurinto TRom) for italics, but still use the normal oblique style for slanted. But the naïve/obvious approach doesn't do it—italics are unaffected. Help? Here's what I tried: \starttext \definefontfamily[Kurinto] [rm] [Kurinto Text][it=file:KurintoTMod-It] %\definefontfamily[Kurinto] [it] [Kurinto TRom] % Doesn't work either \definefontfamily[Kurinto] [sl] [Kurinto Text] \definefontfamily[Kurinto] [ss] [Kurinto Sans] \definefontfamily[Kurinto] [mono] [Kurinto Mono] \definefontfamily[Kurinto] [mm] [Latin Modern Math] \setupbodyfont[Kurinto,12pt] \startbuffer[line] The quick brown fox jumps over \stopbuffer \startbuffer[sample] \startTABLE \NC \type{\normal} \NC \normal{\getbuffer[line]} \NC \NR \NC \type{\italic} \NC \italic{\getbuffer[line]} \NC \NR \NC \type{\slanted} \NC \slanted{\getbuffer[line]} \NC \NR \NC \type{\bold} \NC \bold{\getbuffer[line]} \NC \NR \NC \type{\bolditalic} \NC \bolditalic{\getbuffer[line]} \NC \NR \NC \type{\boldslanted} \NC \boldslanted{\getbuffer[line]} \NC \NR \NC \type{\smallcaps} \NC \smallcaps{\getbuffer[line]} \NC \NR \stopTABLE \stopbuffer \startlines \type{\serif} \serif{\getbuffer[sample]} \stoplines \stoptext

Cropmarks
by John Was 18 Jun '25

18 Jun '25

Hello I'm getting to grips with page layout and hope that it will be possible to set up crop marks on all four corners of each page. Currently when I give 'marking=on' I'm getting a crop mark top left on an odd-numbered page and top right on an even-numbered page, and it does look as if these are in the correct position; but the printer will want all four corners of each page to be demarcated, and I haven't found a setting to achieve that.

Can Bytemaps be overwritten?
by Keith McKay 17 Jun '25

17 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
