non standard tag for structure
by Pablo Rodriguez 10 Apr '25

10 Apr '25

Hans, with the following source, veraPDF-1.29.11 complains about a non-standard tag named /documentpart: \setuptagging[state=start] \setupbackend [format=PDF/A-3a, intent=sRGB IEC61966-2.1, level=0] \starttext whatever \pdfbackendactualtext{abc}{hoh} \stoptext The problematic object reads: 4 0 obj << /K 28 0 R /ParentTree 5 0 R /RoleMap << /break /NonStruct /document /Document /documentpart /DocumentFragment /navigationpage /NonStruct >> /Type /StructTreeRoot >> endobj If I replace (according to https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008…) /documentpart with /Part, validation in veraPDF is perfectly fine. BTW, /DocumentFragment seems not to be included in PDF-1.7 (https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008…) According to https://github.com/veraPDF/veraPDF-model/blob/4c8e855b68546547971121281ff2a…, /DocumentFragment seems to be only available in PDF-2.0. Providing a patch for strc-tag.lmt would be easy, but this would affect to ua-2 (which may use /DocumentFragment). Many thanks for your help, Pablo

regular online meet-up
by Henning Hraban Ramm 09 Apr '25

09 Apr '25

You’re invited to our regular online meet-up, this upcoming Wednesday, April 9th, 19:00 CEST (UTC+2) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://u.mtxrun.eu/ctxmtg) ConTeXt users of all levels are welcome! Looking forward to seeing you, Hraban (Same blurb as always:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the URL above, 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 at a time, 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, esp. with mobile connections. * Sometimes leaving and re-entering helps. * 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/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...

character replace
by Alan Caruanambo 09 Apr '25

09 Apr '25

Hi, I'm using a font (only in the headers) that doesn't have Spanish characters. What I want is for it to automatically replace the text with a custom font when I type it in the header. Sample: \chapter{Peru} ==> Peru (replace ú with u) ========= \definefont[typographercaps][name:typographercaps*default at 35pt] \setuphead [chapter] [align=middle, color=darkred, number=no, style=\typographercaps] \starttext \dorecurse{5}{\chapter{ann chapter} \input knuth} \stoptext
