image with rounded corners
by Henning Hraban Ramm 12 Aug '22

Hi, can ConTeXt make rounded image corners? Both of my approaches don’t work: \externalfigure[mill][ width=3cm, frame=on, corner=round,radius=1cm, backgroundcorner=round,backgroundradius=1cm, ] \defineoverlay[Mill][{% \externalfigure[mill][width=\overlaywidth] }] \framed[background=Mill,width=3cm,height=4cm, corner=round,radius=1cm, backgroundcorner=round,backgroundradius=1cm, offset=overlay]{} Hraban

Re: [NTG-context] Fwd: Typesetting modern Greek (UTF8) with ConTeXt

Actually, we never had a greek hyphenation pattern file, only for ancient greek. Modern greek in mkii has not encoding defined (we're talking 2005 and before when Tomas made the greek encoding that dealt with utf in pdftex). It has to do with 'setting what are letters' and these modern greek patterns have plenty different. You can patch lang-grk.mkii: \installlanguage [\s!gr] [\c!spacing=\v!packed, \c!leftsentence=---, \c!rightsentence=---, \c!leftsubsentence=---, \c!rightsubsentence=---, \c!leftquote=\greekleftquot, \c!rightquote=\greekrightquot, \c!leftquotation=\greekleftquot, \c!rightquotation=\greekrightquot, % we're missing an encoding for greek \s!patterns=\s!agr, \s!mapping=\s!agr, \s!encoding=\s!agr, % but one can use mkiv / lmtx anyway \c!date={\v!day\ \v!month\ \v!year}] At least you get something. In mkiv and lmtx we have both. Just curious: you're still in mkii?

parameters of (setup)externalfigure, conversions etc.
by Henning Hraban Ramm 12 Aug '22

12 Aug '22

Hi Hans, yesterday you told me about the image conversions in grph-con.lua, and I tried to find out how to use them. Up to know I only knew "mp" for SVG images. I found I can use "gray.pdf" or "cmyk.pdf" to convert an image (JPG or PNG) to grayscale/CMYK, but the resolution isn’t used for downsampling (of course, it’s not mentioned in the command template): \externalfigure[hacker][conversion={gray.pdf},resolution=72] I tried to write my own downsampling converter, but don’t understand how I can hook it into the list of converters: """ local downsample = sandbox.registerrunner { name = "downsample", program = "gm", template = [[convert -compress Zip -sampling-factor 1x1 -density %resolution%x%resolution% -resample %resolution%x%resolution% %oldname% %newname%]], checkers = checkers, defaults = defaults, } programs.downsample = { runner = downsample } """ (I’m not sure if I must calculate the desired pixel size beforehand.) -*-*- Apart from converters, there are several parameters of \externalfigure that I don’t understand and thus can’t document in the Wiki; a few are even not yet documented in the interface files: * equalwidth/equalheight * s/sx/sy * xmax/ymax * prefix, label, comment * bodyfont * mask * frames (≠ frame) * interaction, crossreference * resources * display * order * crop, transform * controls, preview: only related to video and thus obsolete? * hfactor/wfactor: When do these make sense? (I know factor) I accidentally learned that I can use parameters of \framed, but the inheritance from \setupframed is not explicit – some are mentioned, like backgroundcolor, others not, even if they work, like corner (but they don’t affect the image).

TIL: figure combinations
by Henning Hraban Ramm 11 Aug '22

11 Aug '22

You probably know about combinations to place images side by side: \startcombination[3*1] {\externalfigure[cow]}{cow} {\externalfigure[mill]}{mill} {\externalfigure[hacker]}{hacker} \stopcombination Now, the widths aren’t calculated automatically. You could define them on your own: \startcombination[3*1] {\externalfigure[cow] [width=.3\textwidth]}{cow} {\externalfigure[mill] [width=.3\textwidth]}{mill} {\externalfigure[hacker][width=.3\textwidth]}{hacker} \stopcombination But that’s ugly and tedious. Hans did it for you: \definemeasure[combination][ (\textwidth -\effectiveleftskip -\effectiverightskip -\numexpr\combinationparameter\nx-\plusone\relax\dimexpr\combinationparameter\distance\relax )/\combinationparameter] So you can say: \startcombination[3*1] {\externalfigure[cow] [width=\measure{combination}]}{cow} {\externalfigure[mill] [width=\measure{combination}]}{mill} {\externalfigure[hacker][width=\measure{combination}]}{hacker} \stopcombination But that’s still tedious. With the power of \defineexternalfigure: \defineexternalfigure[combination][width=\measure{combination}] (That’s predefined, no need to copy!) \startcombination[3*1] {\externalfigure[cow] [combination]}{cow} {\externalfigure[mill] [combination]}{mill} {\externalfigure[hacker][combination]}{hacker} \stopcombination Beautiful. ;) Have fun, Hraban

How to display these characters
by juh+ntg-context＠mailbox.org 10 Aug '22

10 Aug '22

Dear all, I have this: \starttext \starttyping foo └── bar ├── baz │ └── index.html └── index.html \stoptyping \stoptext The source code is generated with the linux command "tree". The special characters which indicate the folder depth are not displayed. I guess that I could define a fallbackfont. Do anyone know the unicode range that should be covered and the font that has these characters? TIA juh

MetaFun keywords extracted by mtxrun --script interface
by Nicola 10 Aug '22

10 Aug '22

I am updating Vim syntax coloring for Metapost/MetaFun, which is now based on the files that are automatically generated with mtxrun --script interface --vim To test the results, I am opening ConTeXt's own MetaPost files in the editor and check how they look. It seems that the output of the above command is missing several "keywords". For instance: beginglyph, endglyph, anglestriped, numberstriped, roundedsquarexy, starring, dashing, pathpoint, primitive, immutable, etc. Is it because MetaFun keywords are picked up manually?

regular online meet-up
by Henning Hraban Ramm 10 Aug '22

10 Aug '22

You’re invited to join next Wednesday, August 10th, 15:00 CEST (UTC+2) at https://lecture.senfcall.de/hen-rbr-rku-oke ConTeXt users of all levels are welcome! There will be no meet-up in September (since it would be during the ConTeXt meeting); and then on October 12th. (Same blurb as every time:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the above URL, accept the privacy statement, * enter your name, * click "join" (or "start" if you’re the first), * click "with microphone", allow your browser to access it, check the audio. * Your microphone is muted if you join. Activate microphone and/or camera with the buttons at the bottom. * Minimize the default presentation with the "screen" button, bottom right. * If you’d like to share your screen or upload a file, you can make yourself the presenter: Click on your user name, change the setting, then you’ll see the "screen sharing" button beside the camera button; also there’s now "manage presentations" behind the "plus" button. Beware there is only one presenter, so don’t kill someone else’s presentation. [Technical hints] * Sound is usually better if you use a headset (less noise for everyone). * Connection problems are mostly due to low bandwidth or high latency on your side, e.g. with mobile connections. * If audio/video doesn’t work for you, you can still use the text chat. * Screen sharing needs a lot of bandwidth. * BigBlueButton documentation applies: https://bigbluebutton.org/teachers/tutorials/ [Netiquette] * Please use a name that we recognize from here. Some feel uncomfortable with anonymous lurkers. * Mute your microphone while you’re not talking. * It’s nice to show your face at least when you join. * If there are connection problems, stop camera sharing. * The room is set to “everyone’s a moderator“, I trust you... See you, Hraban
