Even with my scanner software I produce always .jpg-images though it is capable to produce .pdf-output too. The only .pdf-files I'm doing are made by ConTeXt-LMTX! I shall append another, interesting MWE. There is a .png-image which is, as it occasionally happens, represented as it should, by ConTeXt. And then the same .png-image to which I added a red frame by GIMP2.10. This one shows artefacts in ConTeXt! I'm adding the .log-file too. There again is a luatex-warning, as I could observe them often in ConTeXt-LMTX: -------------------------------------------------------------- luatex warning > pdfe: invalid 11 0 R object at offset 385741 -------------------------------------------------------------- Please, what does mean it? I fear there is something wrong with the .png-handling of ConTeXt/luatex. The outputs of feh image----red-frame.png gm display image----red-frame.png are looking ok. And GIMP2.10 has produced all image-files.

UTF8 chars in attribute values (XML)
by Pablo Rodriguez 21 May '19

21 May '19

Hi Hans, I’m afraid I found another issue with UTF8 chars in attribute values when printing them. \starttext \startTEXpage[offset=1em] \startXML <tag value="aä" /> \stopXML \stopTEXpage \stoptext Inspecting buff-imp-xml.lua, I understand that "alsoname" should be added to "key". But I don’t know where or how this could be achieved. Sorry for not providing a patch, Pablo -- http://www.ousia.tk

problem with UTF8 chars in XML elements
by Pablo Rodriguez 19 May '19

19 May '19

Dear list, I have the following sample: \startbuffer[demo] <?xml version="1.0" encoding="UTF-8"?> <doc> <título>Title</título> </doc> \stopbuffer \startxmlsetups xml:sample \xmlsetsetup{#1}{doc|título}{xml:*} \stopxmlsetups \xmlregistersetup{xml:sample} \startxmlsetups xml:doc \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:título \title{\xmlflush{#1}} \stopxmlsetups \starttext \xmlprocessbuffer{main}{demo}{} \stoptext ConTeXt has problems parsing <título>. To the best of my knowledge, this is a valid XML element name (sorry, but I don’t have a better reference: https://en.wikipedia.org/wiki/XML#International_use]). How can I get this parsed with ConTeXt? Many thanks for your help, Pablo -- http://www.ousia.tk

interactive link area and scale in LMTX
by Pablo Rodriguez 19 May '19

19 May '19

Dear list, I have the following sample: \setupinteraction[state=start] \enabledirectives[references.border] \def\mypersonalurl#1{\bgroup% \tt\goto{\hyphenatedurl{#1}}[url(#1)]\egroup}% \unexpanded\def\href#1#2{\goto{#2} [url(#1)]} \starttext \mypersonalurl{wiki.contextgarden.net} \scale[width=.5\textwidth] {\mypersonalurl{wiki.contextgarden.net}} \stoptext Interactive link areas are fine in latest beta (2019.05.18 10:57) with LuaTeX-1.10, but with LuaTeX-2.0, they aren’t scaled. Could anyone confirm the issue? Many thanks for your help, Pablo -- http://www.ousia.tk

EB Garamond works in TL2016 ConTeXt but not in latest ConTeXt
by nyssus 19 May '19

19 May '19

In my source ConTeXt file I have the lines: \usetypescriptfile[type-ebgaramond] \setupbodyfont[ebgaramond,10pt] ConTeXt from TL 2016 correctly formats the text in EB Garamond, as can be shown by the prescence of mkiv lua stats > loaded fonts: 2 files: ebgaramond12-regular.otf, texgyrebonum-math.otf whereas the latest ConTeXt gives: fonts > defining > font with asked name 'EBGaramond12-Regular' is not found using lookup 'file' fonts > defining > unknown font 'EBGaramond12-Regular', loading aborted fonts > defining > unable to define 'EBGaramond12-Regular' as 'ebgaramond-10pt-rm-tf-0--0' and typesets the text with TeX Gyre Bonum Math. I have the EBGaramond fonts installed, set the OSFONTDIR path in setuptex, etc. What exactly is wrong here?

Creating one's own style
by Dmitry Starostin 18 May '19

18 May '19

Thank you for the instructions on how to make one's own style. I only need to change the formatting in the bibliography list, the formatting of the notes in the text is entirely up to the requirement. A strange effect (full MWE in attachment): \btxdoifelse {address} { {\btxspace \emdash \btxspace \btxflush{address} \btxcomma} } \btxdoifelse {year} { {\btxspace \btxflush{year} \btxperiod} } gives "year 2000", but throw out the "address" part, and the year goes straight without the 'year' part. \btxdoifelse {year} { {\btxspace \btxflush{year} \btxperiod} } if you add publisher between the address and the year, then it says "publisher Brill" \btxdoifelse {publisher} { {\btxspace \btxflush{publisher} \btxcomma} } Where does it pull it up from?

Questions on columnsetspan (and grids and backgrounds)
by Mikael P. Sundqvist 18 May '19

18 May '19

Hi, I have for some hours tried to understand how to work with columnsetspans (I'm trying with an updated lmtx), and have some questions. 1) Is it only the floats that has the long list of placement options (given on p. 18 in the columnsets manual), or should they also apply to columnsetspans and columnsetareas? (I cannot get it to work with "default=fxtb:2*10" and similar options for other elements than floats). It would be useful to have it for other type of elements as well. 2) What is the current correct way to get back on grid after formulas? The only key that had lead me to something that seems to work in \setupformulas is "option=depth". Is that the way to go? 3) This is a bit unrelated, but is it possible to set page backgrounds on specific page. Something like \setupbackgrounds[page][page=3, ...] (I cannot find any keys for this in setup-en.pdf). Right now I can set it for an odd and an even page, but then if I want a background on the page after that, I have to put that code at the place where it will be used. (I got an error with \startpostponing[+1] ... \stoppostponing) 4) To be a bit more concrete on the first issue: In the example below, how can I place the columnsetspan at the bottom right? Second and third column, 10 lines down? I attach the result of running this file. /Mikael \setuplayout[grid=yes] \showgrid \definecolumnset[three][n=3] \definecolumnsetspan[two][ n=2, background=color, backgroundcolor=lightgray, ] \starttext \startcolumnset[three] \samplefile{knuth} \startcolumnsetspan[two][default=btrl] \samplefile{ward} \stopcolumnsetspan \dorecurse{5}{\samplefile{knuth}\par} \stopcolumnset \stoptext

Remove italics from bibliography list

I tried several variants, but I cannot find where exactly the switch happens. \definebtx[apa:list:title:incollection][apa:list:title][style=] \definebtx[apa:list:title:book][apa:list:title][style=] \definebtx[apa:list:journal][apa:list][style=]
