Access ConTeXt dimensions in Lua
by Henning Hraban Ramm 09 Oct '16

09 Oct '16

Hi all, I’m trying to write some dimensions to a file, e.g. \startluacode io.savedata("settings.txt", context("\\textwidth")) \stopluacode But that context() construct is nil. There’s probably a simple solution... ;) Greetlings, Hraban --- http://www.fiee.net http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer) GPG Key ID 1C9B22FD

How do I compile a "flat" pdf?
by Bomber K. 09 Oct '16

09 Oct '16

Hi guys, I am trying to create a pdf which contains some graphics that I created. I want to pass my PDF digitally but I don't want users to be able to right-click on a gfx and save it. I think this is called "flattening". Is there a way in CTX to create such a file or do I have to recompile the PDF with 3rd party software? Is there maybe even a way to flatten only specific objects like, only one picture of many or all, and leave form fields unflattened? Thanks, Sebastian

Recommendations on presentations
by Jan U. Hasecke 08 Oct '16

08 Oct '16

Hi all, Keynote is the only software that ties me to MacOS X. I would like to copy some of its presentations styles to ConTeXt (MKIV). What is the best way to do this? I read about simpleslides and looked into the code but I am unsure whether I start from a simpleslides example. Is it better to simply define the layout from scratch? juh

Underlining formulas and units
by Florian Leupold 07 Oct '16

07 Oct '16

Dear list, underbar behaves weirdly when it comes to indexes, exponents, and units: \starttext \underbar{$F_C=\unit{1e2 newton}$} or \underbar{\unit{1e2 newton}} \stoptext Am I doing something wrong? Is there maybe a setting to correct for this? Thanks, Florian

Bug in \usetikzlibrary{datavisualization}?
by Florian Leupold 07 Oct '16

07 Oct '16

Dear list, Sorry for posting a duplicate, but I guess my previous post got lost during the conference... When one tries to load the TikZ data visualization library, the documents does not compile anymore. The error is “.../tikzlibrarydatavisualization.code.tex: ! Missing number, treated as zero”. I have also tried this using ConTeXt online, to the same end: http://live.contextgarden.net/cgi-bin/output.cgi?id=jSjLZO \usemodule[tikz] \usetikzlibrary{datavisualization} \starttext Hello world! \stoptext Is this a known bug or could I somehow fix this to get data visualization to work? Best, Florian

"marking=one" with marks on more than the first page
by Pablo Rodriguez 07 Oct '16

07 Oct '16

Hans, the following sample puts the cut marks on each page: \showframe \setuppapersize[A5][A4] \setuplayout [marking=one, location=middle] \starttext \ctxlua{for i=1,10 do tex.print("\\startpagemakeup\\filterpages[setup-en.pdf][" .. i .. "][width=0cm]\\stoppagemakeup") end} \stoptext Page makeups is the only way I have to get full pages imposed. But with those, "marking=one" doesn’t work. Is there a way to solve this? Many thanks for your help Pablo -- http://www.ousia.tk

Taking extensible math accents from fallback font
by Aditya Mahajan 07 Oct '16

07 Oct '16

Hi, Is it possible to take particular math accents from the fallback font. In praticular, I want to use NeoEuler as the math font, but want the \widehat and \widetilde accents to be taken from Pagella. This is because the widetilde accent of neo euler does not change the the size of the glyph. Until that is fixed, using the accent from another font is a stopgap solution. Thanks, Aditya

not understanding basic imposition
by Pablo Rodriguez 06 Oct '16

06 Oct '16

Dear list, sorry, but I don’t understand why the second imposed page is reduced from margins in this sample: \showframe \setuppapersize[A5][A4] \setuplayout [backspace=0pt, topspace=0pt, marking=page, location=middle, header=0pt, footer=0pt] \starttext \startpagemakeup \filterpages[setup-en.pdf][1][width=0cm] \stoppagemakeup \filterpages[setup-en.pdf][1][width=0cm] \stoptext Could anyone explain me why this happens and how to get the result from first page (no reduction) without the makeup? Many thanks for your help, Pablo -- http://www.ousia.tk

marks on the first page only
by Pablo Rodriguez 06 Oct '16

06 Oct '16

Hans, would it be possible to have a "first" value added to the "marking" key from \setuplayout that prints cut marks only on the first page of the document? In some cases, having cut marks in all pages is unnecessary. Or even unpractical, because some printers slightly move the marks when printing (they don’t print the text exactly on the same position on each page [it happens in most copyshops]). I would need this for the imposition I asked about yesterday (https://mailman.ntg.nl/pipermail/ntg-context/2016/087038.html) Sorry for insisting, but I need to solve the issues for something I have to send to a copy shop today. Many thanks for your help, Pablo -- http://www.ousia.tk

floating figure hanging into the margin
by Csikos Bela 06 Oct '16

06 Oct '16

Dear list members: How can I make floating figures hang into the side margin area in context? That is, part of the figure in the text area and other part of the figure in the margin? Is it possible? I attach a pdf showing an example. I don't need compete solution, only a hint where to start. Thanks in advance, bcsikos
