Moving horizontally a whole ensemble of layers in the same run?
by Rudolf Bahr 17 Dec '19

17 Dec '19

Hi Hans, assume we fixed between "\definelayer" and "\flushlayer" a whole ensemble of layers on a page. And by calculating per luacode we determined the leftmost and the rightmost edge of the ensemble and would now like to horizontally centre the ensemble. We don't know the rightmost edge before we placed the last layer. By luacode we can calculate how much the centring movement should be, because we know "\textwidth", but we cannot save the calculated centring value in the context program for another run. Saving the luacode values of hundred of pages in flattened lua tables would be possible, but rather awkward; the problem of relating pages to tables would arise, especially when pages are taken out or additional pages are inserted. Do you know a way to settle the centring in the same context run in which the layers are placed? Could "\flushlayer" perform it somehow? Rudolf

Very strange behaviour of itemize, \quotation and \dots
by Otared Kavian 17 Dec '19

17 Dec '19

Hi Hans, Last week I sent you a PDF showing a strange behaviour of \startitemize and \quotation in LMTX. I finally could nail down the origin of the problem: it seems that if the command \setupsynctex[state=start] is present twice at the beginning of the document, then the combination \item and \quotation and \dots prevents the item to be shown correctly… (In my case I was typesetting a document with the above command in which a file containing it also was \input). Below is the minimal example and its PDF. Best regards: OK % begin file: bug-itemize-lmtx.tex \setupsynctex[stat=start] \setupsynctex[state=start] % if this is removed then everything is fine… \setupquotation[style=italic,left={«~},right={~»}] \showframe \starttext \startitemize[n] \dorecurse{4}{\item This item \quotation{is shown correcly\dots} \item This item \quotation{\dots is not shown correctly}} \stopitemize \stoptext % end file: bug-itemize-lmtx.tex

Dear Hans, I reinstall a new beta and test the previous file. (LuaMetaTeX: version 2.03.4, ConTeXt version: 2019.12.16 18:54, format: 2019.12.17) The problem is gone! The space in the aligned display math mode is normal. Thank you so much. Best regards, Dalyoung

Dear Hans, Here is a small example which shows a strange spacing in the aligned display math mode. The same code is OK in both inline mode and just display mode, but it is not good in aligned mode. I hope that it helps your fix . Thank you.

Thank you

ConTeXt is not causing me any problems. I just wanted to thank the developers for creating such a useful tool, and for providing such excellent support. I have just received copies of my 730 page hard cover book that chronicles part of my immediate family's life together, created by programmatically converting Libre Office documents to ConTeXt, and a bit of manual tweaking. It would never have been possible to produce such a book in such a short time without a tool like ConTeXt, and, unfortunately, time is short for me. Thank you again for making it possible to create such an important book for me and my family.

Dear Mikael, I also confirm your problem. I am using "ConTeXt ver: 2019.12.06 21:40 MKIV beta fmt: 2019.12.9 int: english/english” However, if you change “\Bigl(“ to “\left(“, then the space between left parenthesis and text become narrower. I hope that it will be fixed soon. Best regards, Dalyoung

"error not related to input file"
by Rudolf Bahr 16 Dec '19

16 Dec '19

Hello All, In: LuaMetaTeX, Version 2.03.3 ConTeXt ver: 2019.12.12 19:35 MKIV beta fmt: 2019.12.12 int: english/english I get the following error message: tex error > error not related to input file: tex error > tex: ! Emergency stop tex error > lua: ? tex error > mps: - Sorry, no MWE available. What does this message mean? [1] shows only an empty page. To this point my programm does all what it should with the exception of creating a grey pdf-file-page. My pdf-programs are okular and xpdf. In: LuaTeX, Version 1.11.2 (TeX Live 2020/dev) ConTeXt ver: 2019.12.12 19:23 MKIV beta fmt: 2019.12.13 int: english/english I get a "*" instead of the error message above. And again my program does all what it should, but a grey pdf-page too. Shure, there must be an error in my program. But where should I look for it? I tried several MWEs, but they all worked at their best. Please, any ideas? Best wishes, Rudolf [1] https://wiki.contextgarden.net/error_not_related_to_input_file

LMTXL Tagging and overlay
by Rik Kabel 16 Dec '19

16 Dec '19

Dear list, With the example below (perhaps not minimal, but I have stripped out as much as I could), the second page is set completely in the color of the overlay. This also happens when a layer is used instead of an overlay. When tagging is turned off, the colors are what they should be. When a few lines are removed from the first page, the colors are correct as well, but ... Attached is the resulting pdf. LMTX 20191206 only. MKIV 20191206 is fine. Error on my part, or bug? % \definelayer [WatermarkOverlay] % [repeat=yes, % width=\paperwidth, % height=\paperheight] % \setlayerframed [WatermarkOverlay] % [preset=center] % [foregroundcolor=red,frame=off] % {\scale[factor=max]{\rotate[rotation=60.0]{~Oops!~}}} \defineoverlay [WatermarkOverlay] [{\framed[frame=off, foregroundcolor=red] {\scale[factor=max] {\rotate[rotation=60.0] {~Oops!~}}}}] \setupbackgrounds [page] [background=WatermarkOverlay] %setuptagging [state=stop] \setuptagging [state=start] \setuplanguage [en] [spacing=packed] \setupinterlinespace [2.2ex] \definenarrower [MidOneEm] [middle=1em] \setuplayout [topspace=0.25in, footerdistance=0in, height=fit, width=27em, footer=0.5in, bottom=0.25in, backspace=1.1in] \definepapersize [octavo] [width=6in, height=9in] \setuppagenumbering [location=] \setuppapersize [octavo] \setupbodyfont [Termes,10pt] \starttext \starttitle [title={Naaaa aa aaa aaaa}] \startsubject [title={Baaaaaaaa}] Faaa aaa {\em Naa Yaaa Taaaa} aaaaaaaa aa Caaaa 22, 9990 (aaaa 999): \startnarrow [MidOneEm] {\bi Maaaaaaa Faaaaa, 86; Raaaa Laaa aaa Paaaaa Ta Baaaaa a Laaaaa} Da.~Faaaaa, a aaaaaaaa aa aaa Jaaaaa Iaaaaaaaa aa Raaaaaaa, aaaaaa aa aaaaa aaaa Taaaaa Iaaaaa aa Waaaaaaaaa Haaaaaa aaaa 1925 aa 1928.

GraphicsMagick corrupts TIFF upon PDF conversion
by Thangalin 16 Dec '19

16 Dec '19

FYI, there appears to be a bug with GraphicsMagick. gm convert -density 600x600 illustration.tif m_k_i_v_illustration.tif.pdf Produces: 38812848 Dec 15 22:51 m_k_i_v_illustration.tif.pdf https://i.imgur.com/EByrH6r.png Whereas ImageMagck: convert -density 600x600 illustration.tif m_k_i_v_illustration.tif.pdf Produces: 42343236 Dec 15 22:52 m_k_i_v_illustration.tif.pdf https://i.imgur.com/9DxRVW2.png Re: https://wiki.contextgarden.net/Using_Graphics#Image_Conversion Since GraphicsMagick is used by ConTeXt, is there a way to force ConTeXt to use ImageMagick instead? Thank you!

math align broken
by Mikael P. Sundqvist 15 Dec '19

15 Dec '19

Hi, I hope this report is not a duplicate of another one. I updated lmtx today (from http://lmtx.pragma-ade.nl/install-lmtx/context-linux-64.zip, a fresh install in the folder), and found some strange things with math: The file %%% EXAMPLE \starttext \startformula \startalign \NC \int e^{2x}\sin 3x\,dx\NC=\int\Im e^{(2+3i)x}\,dx\NR \NC\NC =\Im\int e^{(2+3i)x}\,dx\NR \NC\NC = \Im\Bigl(\frac{1}{2+3i}e^{(2+3i)}\Bigr)\NR \stopalign \stopformula >From this we see that $\lim_{n\to+\infty}f(n)=0$. \stoptext %%% gives the attached ex1.pdf. As we can see the spacing inside \startalign \stopalign is wrong. Also, the "lim" in the example after the displayed formula has disappeared. Any clues? /Mikael (I tried in any case to remove cache and rebuild, but since it was a fresh install, I could not see why it could help here. Thought I mention it anyways.)
