t-downsample.lua
by Peter Münster 17 Oct '24

17 Oct '24

Hi, Please find attached a new version of the module, with some ideas from Marco. Later, I'll upload it to modules.contextgarden.net. Here a usage example: \usemodule[downsample] \setupexternalfigures[ location=default, % find hacker.jpg and mill.png cache=/tmp, % where to put the low resolution images resolution=50, % resolution in DPI conversion=downsample.pdf] % use this module \starttext \externalfigure[hacker][width=0.4\textwidth] \setupexternalfigures[resolution=20] \externalfigure[mill][width=4in, height=3in] \setupexternalfigures[resolution=200] \externalfigure[mill][width=4in, height=3in] \stoptext Hans, it would be nice, to apply this patch, to trigger new conversion, when figure dimensions change: --- grph-inc.lua~ 2019-02-14 17:04:12.000000000 +0100 +++ grph-inc.lua 2019-02-17 08:45:38.129971581 +0100 @@ -864,6 +864,14 @@ newbase = prefix .. newbase end local hash = "" + local width = figures.current().request.width + local height = figures.current().request.height + if width then + hash = hash ..

Status of Asymptote
by Alexandre Christe 11 Jan '24

11 Jan '24

Dear all, I'd like to know what is the status of Asymptote in Context. To my knowledge, metapost/metafun only support 2D (except with the additional libraries from Roegel, which would have to be cleaned up a bit). Otherwise, what shall be used for 3D drawings in Context? TikZ? Something else? Thanks in advance. Alex

Re: [NTG-context] checkbox in fields show the word yes
by Andres Conrado Montoya 05 Oct '23

Firefox doesn't show the "yes", nor Acrobat X, but SumatraPDF does. I modified your definition as: \definefield[test][check][cbox][][] And now the "yes" doesn't appear. However, I don't know how this affects the functionality of the form. -- Andrés Conrado Montoya Andi Kú andresconrado(a)gmail.com http://sesentaycuatro.com http://messier87.com http://chiquitico.org ---------------------------------------- Los fines no justifican los medios, porque la medida verdadera de nuestro carácter está dada por los medios que estamos dispuestos a utilizar, no por los fines que proclamamos. ---------------------------------------- “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.

Chemistry in LMTX
by Henning Hraban Ramm 03 Oct '23

03 Oct '23

I tried to update https://wiki.contextgarden.net/Chemistry, since nearly all of the links were dead, and I couldn’t find any documentation about \chemical / \startchemical. In the wiki page you can see that there’s still some working code for chemistry, but it looks very broken. ppchtex.mkiv is apparently still code from 1996 (and can’t work, since neither PicTeX nor PStricks are supported in LMTX any more). chem-str.lua seems to be an updated version by Alan & Hans Did I miss something?

wiki update: Modules
by Henning Hraban Ramm 02 Oct '23

02 Oct '23

I updated the list of included modules in https://wiki.contextgarden.net/Modules and tried to understand what each does. If you know matrices, could you perhaps update the page https://wiki.contextgarden.net/Matrix_in_maths to include the matrix module and the latest enhancements? Hraban

Bug? Text following columns at end of page goes into footer not next page
by Bruce Horrocks 30 Sep '23

30 Sep '23

Two column text that ends near the foot of a page can push the next line into the footer rather than starting a new page. MWE for ConTeXt ver: 2023.09.26 18:19 LMTX :- \setuppapersize [A4] \showframe \starttext Knuth in knolumns \dorecurse{30}{\crlf} \startcolumns \input knuth \stopcolumns This line goes into the footer rather than the next page. \stoptext — Bruce Horrocks Hampshire, UK

formula alignment for mathalign
by Aditya Mahajan 28 Sep '23

28 Sep '23

Hi, The `align` parameter of `\setupformulas` is ignored in mathalign. Consider the following MWE: \setupformulas[align=flushleft,leftmargin=2em] \starttext \startformula A = B \stopformula vs \startformula \startalign \NC A \NC B \NR \NC A \NC B \NR \stopalign \stopformula \stoptext The first display formula is flush left, but the aligned formula is centered on the page. This appears to be a regression compared to MkIV, where the above example works correctly. Aditya

Dear list, I have the following sample: \setuppapersize[A6] \setupitemgroup [itemize][1] [ before={\blank[.125th]}, after={\blank[.125th]}] \starttext one \startblockquote \startitemize \item a \stopitemize \stopblockquote two \stoptext The blockquote disables the space after the list, but not before. Have I hit a bug or am I missing something? Many thanks for your help, Pablo

Issue : compilation error when using mathcases with pagella fonts (and others)
by Vincent Picard 26 Sep '23

26 Sep '23

Hello, Since ConTexT last upgrade (ltmx 2023.09.18 21:13), I have a document that won't compile with ConTexT. The problem seems to occur when using mathcases with some ConTeXt provided fonts, including pagella. This is a minimal not working example : \setupbodyfont[pagella] \starttext \startformula \delta_{ij} = \startmathcases \NC 1 \NC \text{if } i = j \NR \NC 0 \NC \text{otherwise} \NR \stopmathcases \stopformula \stoptext The error is : run callback [44]: ...ext/tex/texmf-context/tex/context/base/mkxl/math-fnt.lmt:56: table index is nil\nstack traceback:\n ...ext/tex/texmf-context/tex/context/base/mkxl/math-fnt.lmt:56: in metamethod 'index'\n ...ext/tex/texmf-context/tex/context/base/mkxl/math-fnt.lmt:104: in function <...ext/tex/texmf-context/tex/context/base/mkxl/math-fnt.lmt:62>\n [C]: in upvalue 'builders_kernel_mlisttohlist'\n [string \"local tonut = nodes.tonut...\"]:43: in function <[string \"local tonut = nodes.tonut...\"]:18>\n (...tail calls...)\n ...ext/tex/texmf-context/tex/context/base/mkxl/math-noa.lmt:2986: in function <...ext/tex/texmf-context/tex/context/base/mkxl/math-noa.lmt:2984> My system is : FreeBSD 64bits Thank you for any help.
