Transparency in PNGs becomes black in PDF/X
by Henning Hraban Ramm 20 Dec '19

20 Dec '19

I think this is the same problem that I had in Bassenge: The transparent part of PNGs like the attached one becomes black if I try to make an PDF/X. I hope that is solvable... \setupbackend[format=PDF/X-1a:2001] \starttext \externalfigure[kinder/esel_kl] \stoptext Best, Hraban

Layer presets / size of type area
by Henning Hraban Ramm 20 Dec '19

20 Dec '19

Hi, I setup a layer to the size of the typearea and expect the corner presets to place my figures into the corners, but \makeupwidth/height are smaller than the typearea (same with \textwidth). Why? Hraban \setuplayout[ width=120mm, backspace=16mm, height=192mm, topspace=6mm, header=8mm, footer=6mm, ] \showframe \definelayer [TA] [x=16mm, y=14mm, width=\makeupwidth, height=\makeupheight] \setupbackgrounds[page][background=TA] \def\Square{\framed[width=1cm,height=1cm]{S}} \starttext \strut \setlayer[TA][preset=leftbottom]{\Square} \setlayer[TA][preset=rightbottom]{\Square} \setlayer[TA][preset=lefttop]{\Square} \setlayer[TA][preset=righttop]{\Square} \stoptext

Style for captions
by Otared Kavian 18 Dec '19

18 Dec '19

Hi all, In the example below, I would like to have the style of the figure's caption to be \itx, but the inline formula is set with a larger body font: is it possible to setup the caption of a float so that a smaller size applies also to the math formula? Best regards: Otared PS: here is the example (not so minimal, sorry…) % begin example-caption.tex \setupcaption[figure][ headstyle={\bix}, style={\itx}] \starttext \startluacode function weierstrass(n,x) local S = 0 for k = 0, n do S = S + 2^(-k)*math.cos(3^k*x) end return S end \stopluacode \startplacefigure[title={The Weierstrass function $\sum_{k=0}^n 2^{-k}\cos(3^kx)$}] \startMPcode{doublefun} draw lmt_function [ xmin = 0, xmax = 4*355/113, xstep =.001, ymin = -2, ymax = 2, sx = 1mm, xsmall = 80, xlarge = 20, sy = 4mm, ysmall = 40, ylarge = 4, xlabels = "yes", ylabels = "yes", linewidth = .015mm, offset = .1mm, code = "weierstrass(5,x)", frame = "sticks", xcaption = "$n = 5$", functions = { [ drawcolor = "darkred", ] } ] xsized .5TextWidth ; \stopMPcode \stopplacefigure \stoptext % begin example-caption.tex

Think of a photo album. To make it interesting the pages should all be different. To this purpose layers are a good means. I'd like to centre the layers on their page without doing so manually and without changig the distances between them. Using luacode one can calculate the distance d between the leftmost and the rightmost edge. Half the difference (\textwidth - d) is the amount to move the whole layer ensemble. My question is now: Does in context exist a possibility to move all layers jointly without correcting all their x-values subsequently? I append the pdf-file of my MWE.

getting modules working on luametatex on Mac Catalina

Thanks to Otared Kavian’s instructions I have luametatex working on my Mac OS 10.15.2 (Catalina). I have a file making use of the annotation module but it fails and the log says that it can’t be found (the texmf-modules folder is empty). What command do I need to download the modules? Thanks for any help, Charlie

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
