[NTG-context] Fira Math: goodies needed?
Hi,
I'm trying to use Fira Math (https://github.com/firamath/firamath).
But this small example yields both limits on the same horizontal axis,
i.e. the 0 is far away from the integral sign:
\definefontfamily [mainface] [mm] [Fira Math]
\setupbodyfont[mainface]
\starttext
\startformula
\int_0^1 e^x
\stopformula
\stoptext
Meanwhile, when I use LaTeX, the 0 is moved to the left and close to
the integral sign:
\documentclass{article}
\usepackage{amsmath}
\usepackage[mathrm=sym]{unicode-math}
\setmathfont{Fira Math}
\begin{document}
\[
\int_0^1 e^x
\]
\end{document}
In both cases
/opt/texlive/2023/texmf-dist/fonts/opentype/public/firamath/FiraMath-Regular.otf
is used...

Below are the result showing the number of overfull boxes for these
novels using the setups in the file spac-imp-tests.mkxl . See the manual

Test2 30 8
Test3 62 23
Test4 89 40
Test5 28 9
Optional1 55 19
Quality 74 32
Decent 39 11
From these initial tests one can see that Test2 gave the lowest number
of overfull boxes. So I edited test two, ran it, and the results are below.
Test Novel1 Novel2
Test2b 11 0
My setup for test 2b is as follows:
\startsetups align:pass:test2b

\tolerance 200
\parpasses 3
classes \indecentparpassclasses
threshold 0.025pt

adjustspacing 3
adjustspacingstep 1
adjustspacingshrink 20
adjustspacingstretch 40
emergencystretch .25\bodyfontsize
\relax
% \linebreakpasses\plusone
\stopsetups
The only difference between test 2 and 2b are that I increased the
tolerance in each of the three passes.
In novel 2 this was successful in eliminating the overfull boxes but not
in Novel 1 although I noticed that majority of overfull boxes were above
1pt with the largest about 12pt in Novel 1.
I am at the stage now where I need some kind of strategy to
reduce/eliminate overfull boxes, other than changing the tolerance, and
I'm hoping for some advice from the community. Suggestions for further
reading particularly on the commands in \setupalignpass and their usage
would be appreciated and on the best way to tackle overfull boxes.
you're too tolerant (stick to 200), you can even start out with
pretolerance 50 and tolerance 150 and then in the passes 200

Thomas, I actually set OSFONTDIR=. which seems to be a sane default. I store specific font files with projects (along with a copy of the ConTeXt distribution used to typeset the project).

[NTG-context] Convert tif to jpg (instead of pdf)
Hi, According to the documentation, it is possible to automatically convert TIFF images to a format supported by LMTX via GraphicsMagick. https://wiki.contextgarden.net/Using_Graphics#Image_Conversion However, by default this produces pdf files which are quite huge. is it possible to instruct grapichsmagick to convert tiff images to jpg instead of to pdf ? There's an example on the linked page in the documentation, but I have to admit that I don't quite understand what I should do...

\startxmlsetups xml:fig:graphic
\externalfigure[\xmlatt{#1}{xlink:href}]
\stopxmlsetups
This also works for normal spaces, but is there a way to decode/expand the %20s
to regular spaces?
I've tried with some Lua, but I don't really know how to pass data around.
%
\startluacode
function replaceSpaces(s)
result = string.gsub(s, "%%20", " ")
context(result)
end
\stopluacode
\define[1]\replaceSpaces{\ctxlua{replaceSpaces("#1")}}
\startxmlsetups xml:fig:graphic
\externalfigure[\replaceSpaces{\xmlatt{#1}{xlink:href}}]
\stopxmlsetups
%
Any hints, why this does not work?`
Also, maybe there's a simpler way for this kind of scenario?
Best,
Denis
