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 23 Jun '20

23 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 — currently stored as ‘unpublished’ or ‘misc'.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

I think that i found the reason so i'll do a new upload later. There have been a few (not that large) changes in the engine wrr to (1) font memory used at the tex end (not dramatic but for huge fonts it matters), (2) some (potential) improvements of hz and protrusion (removing dead code and improving directional awareness) and (3) normalzation of node lists (very experimental but won't kick in normally).

Anyone? After updating LMTX to the latest version 2019.11.28, context stopped working, only to produce core dumps ... Any hints as how to resolve this?
