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 ..

Undefined control sequence: \pdfpxdimen
by Aditya Mahajan 22 Jun '20

22 Jun '20

The drops module uses the primitive \pdfpxdimen in a couple of places, but that is no longer defined in the current beta. What is the equivalent command now? Examples of usage: \pdfpxdimen1in\relax\divide\pdfpxdimen\numexpr\dropsparameter\c! resolution\relax % set actual pixel dimension Aditya

Outputting custom types in MKiv bibliography
by Mike O'Connor 11 Mar '20

11 Mar '20

Hello, I’m trying to create my first publication using ConTeXt mkiv. All going well except for the bibliography formatting. Previously I have used LaTeX, standard entry types in BibTeX, and custom output formats using Biblatex. My publication cites lots of historical sources, viz.: (1) Newspaper articles — currently stored as ‘article’ types in BibTex. (2) Archival sources (historic letter, some leather-bound volume, a catalogued box of old photographs, etc.) — currently stored as ‘unpublished’ or ‘misc'. I would prefer to store these (in BibTeX, buffer, lua, or xml) as custom types (eg. ‘newspaper’, ‘archivalItem’), create setups for how they are output and which fields I output. I found a ’newspaper’ type (and other non-BibTeX types) defined in publ-imp-apa.mkiv as: \startsetups btx:apa:list:newspaper \fastsetup{btx:apa:list:article} \stopsetups I hoped this would mean I could output something: Boxing. (1903, September 13). The Sunday Times, p.8 However, if I create an item of type 'newspaper’ and \cite it I get an output of all stored fields: newspaper: [day: 13] [journal: {The Sunday Times}] [month: 09] [pages:8][title: {Boxing.}] [type: newspaper article] [year: 1903] A similar thing happens if I try to cite the standard BibTeX type ‘misc’. If I store the newspaper item as type ‘article’ I get: “Boxing.”, The Sunday Times, 8, 1903. (missing day and month) Is it relevant that there is a problem when I include \showbtxfields[rotation=30] in my document? The resulting table has ‘*’ for fields in ‘article’, ‘book’, ‘demo-a’, ‘demo-b’ but the columns for ‘newspaper’ and ‘misc’ are empty. Any pointers gratefully received. Cheers, Mike O’Connor P.S. I am working in TeXShop on OSX (10.11.3), and it reports: This is LuaTeX, Version beta-0.80.0 (TeX Live 2015) (rev 5238) ConTeXt ver: 2015.05.18 12:26 MKIV current fmt: 2016.3.19 int: english/english

body text invades space for notes
by Pablo Rodriguez 04 Mar '20

04 Mar '20

Dear list, I’m afraid to admit that ConTeXt notes are increasily problematic for me. I don’t think this is special to me and I hope we can discuss the general issue. Bottom notes are somewhat tricky in ConTeXt. The user expects that these notes (either footnotes, or linenotes) aren’t moved to the next page. I mean, no reader expects to find a full footnote in the next page from the one that calls it. (At least, I have never seen that in any book read or paged through.) There may be good reasons for that, but ConTeXt doesn’t enable this by default. Both options "split=verystrict" and "scope=text" have to be used in "\setupnote". This translated in wrong space before notes when paragraph form was used. I was very interested to use these (line)notes for critical editions, but sometimes the text run into the notes. I’m afraid that left linenotes extremely problematic to be used. With the arrival of LMTX, space before footnotes is more problematic than before. No paragraph notes, see the attached sample (wrong-6.png). In other cases, ConTeXt seems to ignore totally that the page bottom contains footnotes. I cannot provide minimal samples. Consider that if it were so easy to reproduce, problably the issue would have been gone long ago. Even when one avoids the problematic bottom partition (which I did in that case by removing the "before" option from "\setupnote[footnote]"), there is clearly an issue with the footnote having its space before remaining blank from the body text (wrong-2.png). My first question is why the bottom notes have problems to preserve the space before them (and simultaneously remain in the same page where they come from). This applies also for paragraph notes. My second question is what can be improved to achieve what may be considered as a basic typographic feature. Sorry for not providing more than output samples. Bear with me. I may not be an expert user, but I think I’m a frequent ConTeXt user. And I don’t think it is totally wrong to consider this a basic feature that needs to be improved. Many thanks for your help in advance, Pablo -- http://www.ousia.tk

Some questions regarding math typesetting
by TeXnician 29 Feb '20

29 Feb '20

Dear list, while doing some math typesetting, I have found the following features not working in LMTX: 1. Non-displaystyle operators are simply not shown (try \sum or \lim in text or scriptstyle). This works in MkIV (and iirc in LMTX versions from before november). 2. \underbrace{x}_{y} stopped working. It produces an underbrace but the subscript is not centered below the brace. It will show up as right subscript. This works in MkIV. 3. \startformulas does not allow numbering formulas because the number will run into the next column. I have posted this at https://tex.stackexchange.com/questions/518262/context-number-formulas-side… and Henri Menke tested that it broke in 2017. Aditya Mahajan mentioned that it is a bug. For the upper two cases: Is anything wrong with my LMTX installation or did I miss some upgrade instructions for math in LMTX? Many thanks for an answer.

[HOWTO] spanning xtable cells
by Floris van Manen 07 Feb '20

07 Feb '20

Does anyone knows a hint to get the stacked boxes to the correct size? When usinig non-zero values for the options spaceinbetween and/or columndistance the cells of the xtable will not properly size when spanning over rows and/or columns. e.g. \starttext \startxtable[spaceinbetween=2mm, columndistance=2mm, corner=round] \startxtablebody \startxrow \startxcell[ny=3] a1 \stopxcell \startxcell[nx=2] a2/3 \stopxcell \startxcell[ny=3] a4 \stopxcell \stopxrow \startxrow \startxcell b2 \stopxcell \startxcell b3 \stopxcell \stopxrow \startxrow \startxcell c2 \stopxcell \startxcell c3 \stopxcell \stopxrow \startxrow \startxcell[nx=3] d1/2/3 \stopxcell \startxcell d4 \stopxcell \stopxrow \startxrow \startxcell e1 \stopxcell \startxcell e2 \stopxcell \startxcell e3 \stopxcell \startxcell e4 \stopxcell \stopxrow \stopxtablebody \stopxtable \stoptext
