Hello. So, I have found that Wolfram Mathematica provides fonts with complete script, Gothic (Fraktur) and blackboard letters, in styles compatible with Times, Helvetica and Courier, in normal and bold weights. I want to ask a question on the main site asking how to use them in LaTeX as they don't have a MATH table, and the letters are in private use areas.

I wanted to ask if it is permissible to share the font files while asking the question. I couldn't find any official Wolfram site distributing these fonts, and I found them in the system files of my Mathematica distribution.

@ApoorvPotnis In previous versions of Mathematica, those fonts came as type1 (.pfa). I remember that I did have presentations with monotype math and thought that was a bit fun. Since a few releases (time flies) they seem to distribute the fonts in a different way, and as you say, they do not seem to be "real math fonts". I have no clue how to, if possible, use them as math fonts in any of the unicode math engines. If possible. Also, I guess there is a doubt about if one is allowed to.

@ApoorvPotnis if they do not have a MATH table, you are out of luck. there have been other questions - not about these fonts, but e.g. adf fonts (venturis?) and one of the minion-ish fonts - and the answer is the same. I'll see if I can find the question.

Q: Possible to use MnSymbol with LuaTex?

I want to use the Minion Pro font together with math symbols from MnSymbol (http://www.ctan.org/tex-archive/fonts/mnsymbol). Is this possible? It has already been discussed here -> http://www.latex-community.org/forum/viewtopic.php?f=48&t=16231. No solution has been found but this was over 2 year...

@cfr l3build stuff not forgotten - I hope to get to some of it today

Also have L3/L2e issues and some siunitx ones ...

Plus day job of course :)

@JosephWright thanks. I am not sure whether what I have actually works, but I think it does for everything which builds with a tex-based toolchain. i.e. not berenisadf. but even that tests OK with my attempt at isolation. but the way I'm doing it for check is particularly ugly.

  if not checksearch then
    checkopts = checkopts
      .. " --cnf-line=TEXMFAUXTREES={} --cnf-line=TEXMFHOME={} --cnf-line=TEXMFLOCAL={} --cnf-line=TEXMFCONFIG=. --cnf-line=TEXMFVAR=. --cnf-line=VFFONTS=."
      .. localtexmf() .. " --cnf-line=TFMFONTS=."
      .. localtexmf() .. " --cnf-line=TEXFONTMAPS=."
      .. localtexmf() .. " --cnf-line=T1FONTS=."
      .. localtexmf() .. " --cnf-line=AFMFONTS=."
      .. localtexmf() .. " --cnf-line=TTFFONTS=."
      .. localtexmf() .. " --cnf-line=OPENTYPEFONTS=."

whereas for build, I can do

  -- steal from l3build-check.lua
  local preamble =
    -- would it be simpler to copy the typesetting sandbox here?
    -- paths in the logs don't matter and copying localdir complicates things a bit
    -- No use of localdir here as the files get copied to testdir:
    -- avoids any paths in the logs
    os_setenv .. " TEXINPUTS=." .. localtexmf()
    .. (buildsearch and os_pathsep or "")
    .. os_concat ..
    -- no need for LUAINPUTS here
    -- but we need to set more variables ...?
    (buildsearch and "" or

which is not pretty, but at least doesn't require all the --cnf-lines. seems like there should be a more straightforward way ....

@cfr I see. Thank you.

@mickep It seems they provide type1 versions of some fonts, but not the ones I mentioned, in version 14.1. Did they use to provide a type1 version of the MathematicaSans fonts (Helvetical clone)? I suppose that could be very useful in presentations. That Courier-like math looks good to me.

I found out that Micropress used to sell Helvetica Math in type 1. It seems that Micropress is out of business. Are the type1 files available somewhere? Also, is it legal to use fonts of out-of-business foundries?

Hi all, can someone please point me to when and where the error ! error: (writejpg): image dimensions have changed gets thrown? greppin texmf-dist didn't help

David Carlisle

09:14

@JosephWright I see you broke colortbl :-)

@Lupino ./luatexdir/image/writejpg.c: normal_error("writejpg","image dimensions have changed");

Lupino

@DavidCarlisle hm i assume the .c files are not part of a common texlive-distro?

Ulrike Fischer

@DavidCarlisle ?

Lupino

09:30

@DavidCarlisle nevermind, found the files

Joseph Wright

@DavidCarlisle ??

David Carlisle

@JosephWright github.com/lvjr/tabularray/issues/512#issuecomment-2469539491

@Lupino the souces for the engines are not distributed (but are available on github or tug's svn, and other places)

@DavidCarlisle i get errors like warning (readjpg): Bad Exif resolution 0dpi x 0dpi (zero or negative value of a signed integer) for some images which lead sometimes to arithmetic tex-errors; is this something tex can fix or are the images('s meta data) broken?

also interesting; the readjpg-warnings differ from tex run to tex run…

now i get `warning (file images/ts_std_anth_06758_sl_image20.jpg) (readjpg): Exif resolut
ion 1dpi x 1dpi differs from the input resolution 300dpi x 300dpi
warning (file images/ts_std_anth_06758_sl_image20.jpg) (readjpg): Exif resolut
ion 1dpi x 1dpi looks weird

warning (internal): arithmetic number too big

warning (internal): arithmetic number too big
! Dimension too large.
<recently read> \dimen@`

Rmano

@Lupino how are you including the figure? If the DPI metadata is broken and you ask for any calculation that involves the original DPI you'll get an error...

Lupino

@Rmano basic \includegraphics and some voodoo to get them tagged… other images in the same document work perfectly thou

i just compared the exiftool output from working vs. non-working images, those that work have Exif Image Width/Height set, those that throw the warnings don't, they only set Image Width/Height; could that be it?

oh, and also, exiftool for the broken images returns Warning: Bad offset for IFD0 StripOffsets could that be related to the readjpg warnings?

@DavidCarlisle I'd forgotten about that

@DavidCarlisle The .dtx is a bit vague - why does colortbl use fill glue in the first place?

David Carlisle

@JosephWright it needs to have a higher order than any glue in the entry otherwise the glue balancing to stretch the background panel goes wrong:

% "c" code: This used to use twice as much glue as "l" and "r" (1fil
% on each side). Now modify it to use 1fill total. Also increase the
% order from 1fil to 1fill to dissuade people from putting stretch glue
% in table entries.

@Lupino impossible to say, you can use another tool to interogate the exif data and see if it really is specifyig a resolution of 0 or 1 dpi or whether luatex is just confused.

Hmmm... I can confirm tex.stackexchange.com/q/730649/38080

Joseph Wright

@DavidCarlisle I have a plan and will sort for a v3.3.23 release - I have a few bugs to pick off, then back to v3.4 development

Paulo Cereda

@JosephWright ooh a cunning plan?

Joseph Wright

@PauloCereda Indeed

@PauloCereda Just mentioned youtube.com/watch?v=063jQAM6N8I at work :)

Skillmon

@Rmano so does texlive.net

Paulo Cereda

@JosephWright ooh

@UlrikeFischer I knew i had seen it somewhere:-)

Ulrike Fischer

@DavidCarlisle and I see Herbert is turning to you with my issue ;-)

David Carlisle

@UlrikeFischer naturally I will blame you

Paulo Cereda

@DavidCarlisle ooh

@Rmano fosstodon.org/@[email protected]/113469045616399739

Paulo Cereda

@samcarter olé!

samcarter

14:45

@PauloCereda :)

Rmano

16:13

@PauloCereda Well, ¡olé! to be nitpicking (and yes, @samcarter, I agree that the Spanish factorial does not need brackets around ¡n-k!). (Jokes apart, in my opinion as Italian, ¡ is not very useful --- you can change the intonation at the end anyway, while ¿ is very useful --- the Italian linguist Canepari adopted it in some book).

Paulo Cereda

@Rmano ⸮oh no?

Rmano

@PauloCereda oh, a glottal stop 😆

Paulo Cereda

@Rmano ooh

samcarter

@Rmano too much pre-planing for my taste. How should I know what kind if sentence I'm going to write? :)

Rmano

@samcarter Yes but think about the fine points... marking differences between "¿Do you know it?" and "Do you ¿know it?" ;-)

samcarter

16:35

@Rmano Feature request: \dim_eval:n should be able to convert find points to normal points :P

("find" should have been "fine", sorry)

@DavidCarlisle Very advanced secrets.

Paulo Cereda

18:24

@mickep ooh

mickep

@PauloCereda Indeed, only Australian ducks know them...

Skillmon

20:18

@samcarter Well, in German you know after the second word. Most of the time after the first.

samcarter

20:41

@Skillmon ... still more time than before the first word :P

cfr

21:05

@Skillmon @samcarter in welsh, you usually need to know before the first letter. though in formal stuff, you can delay for a word ....
