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 ..

Re: [NTG-context] checkbox in fields show the word yes

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.

arm osx
by Hans Hagen 30 May '22

30 May '22

Hi, Thanks to Mojca's persistent efforts we now generate arm osx binaries on the build infrastructure, so lmtx now ships native arm bins for apples. There are also intel solaris builds now but no installers for those platforms (yet).

XML Namespaces and XML Setups
by Christoph Reller 24 May '22

24 May '22

Dear List, Consider the following MWE: \startxmlsetups xml:demo:base \xmlsetsetup{#1}{tag}{xml:demo:tag} \stopxmlsetups \xmlregisterdocumentsetup{demo}{xml:demo:base} \startxmlsetups xml:demo:tag %\doif{\xmlnamespace{#1}}{o}{NameSpaceO:} \xmlflush{#1} \stopxmlsetups \starttext \startbuffer[test] <?xml version="1.0"?> <root xmlns="NameSpaceA" xmlns:o="NameSpaceO"> <tag>text</tag> <o:tag>text</o:tag> </root> \stopbuffer \xmlprocessbuffer{demo}{test}{} \stoptext My questions: - Is there a good way to have a separate XML setup for each XML namespace? - Alternatively, one has to do the distinction within the same XML setup. In this case, how do we get the complete namespace? (In this example: "NameSpaceA" and "NameSpaceO") Thanks in advance for your help! Cheers, Christoph

Fuzzy lines
by Henning Hraban Ramm 21 Jan '22

21 Jan '22

Hi MetaFans, is it possible to get lines with Metapost that look like they were drawn with a pencil or brush? Some vector graphics apps (in my case: Affinity Designer) can use such naturally looking brushes for vector graphics (and I don’t know how they do it), but I’d like to automate/parametrize some designs, and that would finally be a reason to learn Metapost...

Hyphenation on digits
by Jairo A. del Rio 03 Nov '21

03 Nov '21

Hi, list. I want to know if ConTeXt provides an option to automatically hyphenate/break digits as if they were alphabetic characters. Example, in a narrow page I expect something like that (I've used (-) for an optional hyphen): *π = *3.141592653(-) 58979323846264(-) 33832795028841(-) 97169399375105(-) ... I found myself unable to read a satisfactory solution in the mailing list archive nor other TeX related resources. Maybe LMTX has some magic for that? Cordially, Jairo

mp-geo Metapost package with ConTeXt
by Gavin 22 Oct '21

22 Oct '21

Hello ConTeXters, I’d like to use the mp-geo Metapost package with ConTeXt to draw simple globes viewed from various directions. The package is here: https://melusine.eu.org/syracuse/poulecl/mp-geo/ It looks like the last update was 2008 and I don’t read French, so I though my chances of getting anything to work were pretty small. However, I was pleasantly surprised that this MWE found the mp-geo package, the necessary Metapost files in the ConTeXt installation, and the data files. \starttext \startMPcode input mp-geo; figure(-10u,-10u,10u,10u); Mercator(3,48,30); fin; end \stopMPcode \stoptext While all of the files were found, it did not produce a globe. Instead I got an error complaining about an invalid character in the data files. This error is repeated for about 20 files (a small fraction of the total). I put the first error and its data file below. All the others are identical with different .dat files. Maybe it’s just an encoding mismatch or a hidden character I can easily delete or replace. On the other hand, maybe I shouldn't even be attempting this? 2008 is a long time ago in ConTeXt time. Feel free to tell me this project is crazy, but if you have an idea how I can make this work, I’d really appreciate it! It looks like a fun package. Thanks! Gavin Error Log: (This error log below is actually from running Metapost directly on just the .mp file with the metapost code above. This error log is slightly more clear in its formatting than the ConTeXt log, but contains the same information.) !
