Weird (?) float placement for specific widths of image
by denismaier＠mailbox.org 10 Apr '24

10 Apr '24

Hi, another graphics/floats question: consider the following example %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setupexternalfigures [location={local,global,default}] \starttext \placefigure{A Cow}{\externalfigure[cow][ height=.5\textheight, ]} \placefigure{A Cow}{\externalfigure[cow][ height=.3\textheight, %height=.4\textheight, ]} \placefigure{A Cow}{\externalfigure[cow][ width=3cm, %width=2cm, ]} \placefigure{A Cow}{\externalfigure[cow][width=2cm]} \placefigure{A Cow}{\externalfigure[cow][width=2cm]} \stoptext%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% On the first page, the images appear stacked above each other while on the second page they appear next to each other. It took me some time to reproduce this behaviour, and I can't claim to understand what is happening. But it seems to be related to the specific widths of the images. When I change them to other values the behaviour disappears. Is this a bug? Anything I can do about this? Best Denis

You’re invited to our regular online meet-up, this upcoming Wednesday, April 10th, 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! Do you have a subject that you’d like to talk about? 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.

Very bizarre bug
by Thomas A. Schmitz 07 Apr '24

07 Apr '24

Hi everybody, this is bizarre, but hear me out: a file that I have has a mixture of xml, TeX and Lua. It compiles cleanly, no problem, on macos and linux. I also have a little raspberry pi on which I have installed lmtx. The file compiles, BUT: it has one additional page. The first page of the document is empty and has the word "on" in the upper left hand corner of the text area. I have checked several times, it always comes out like this. Everything else is exactly the same - context version, file and environment files (everything under git, so really identical). The "on" does not appear if I just make a "hello world" document on the raspi. So my question is: how can I begin to explore where this word creeps in? I suspect it's something in the linux-aarch64 tree or some test for this architecture that is the culprit, but what would be a good way to trace it? All best Thomas

incosistent output of --- dash
by madiazm.eoicc＠gmail.com 07 Apr '24

07 Apr '24

Hi everyone, I'm a bit puzzled because I usually don't get an em-dash when I type tree hyphens. If I use the command \emdash, no problem but when I use the hyphens some days it works... and somedays I see three small hyphens. I tried it on overleaf and of ContextOnWeb with the same inconsistency. If I create a new file it usually works right; but when I overwrite an existing file subtituting a hyphen for three where the dash should be I sometimes get it right and sometimes wrong. It is not the pdf viewer since I get good or bad results in all, the overleaf pdf preview tool, the context on web preview tool and the mozilla integrated pdf viewer. Am I missing something on the use of this ligature? (the question is just out of curiosity, since I plan to create a command that adds a hairspace after or before the dash, since I don't like it to stick to some letters like "o". thanks

PDF/UA-2, WTPDF
by Henning Hraban Ramm 07 Apr '24

07 Apr '24

Quoting a post by Philipp Kiff, https://mastodon.social/@pkiff/112219488889350928: In amongst the release of PDF/UA-2 (PDF for Universal Accessibility) and the new Well-Tagged PDF (WTPDF) standard last month, some PDF professionals may have missed two other new resources that may help explain and view them: 1. Questions and Answers about Tagged PDF from PDF association 2. Acrobat Custom File Info Panels by Peter Wyatt Last month saw the release of PDF/UA-2 and the new Well-Tagged PDF (WTPDF) standard - neither of which revokes PDF/UA-1. And none of those are the same as PDF 1.7 vs 2.0. To many, the landscape of PDF specs may now seem littered with confusing acronyms and versions! For some help disentangling it all, the PDF association has a Questions and Answers about Tagged PDF: https://pdfa.org/resource/tagged-pdf-q-a/ In related news, Peter Wyatt released Acrobat Custom File Info Panels. This is a free extension for Acrobat that adds new panels to the XMP metadata shown when you view File > Properties in Acrobat Pro. The new panels allow you to view the additional conformance claims and dated revisions of ISO standards that can now be included in PDFs, but that aren't currently visible in the standard Acrobat panels. https://pdfa.org/discovering-pdf-metadata/ One thing I realized in reading through the new standards and looking at various sample files this week is that I should probably spend some time learning LaTeX! Both LaTeX and LibreOffice are already capable of producing PDF/UA-2 files, and with some tweaking, LaTeX can produce what appear to be really good WTPDF files. Kudos to both those development teams! https://github.com/latex3/tagging-project/discussions/72 Finally, in case you missed earlier posts from last month, here are links to the official sources for the two new PDF standards that these other resources relate to: 1. PDF/UA-2 https://pdfa.org/iso-14289-2-pdfua-2/ 2. Well-Tagged PDF (WTPDF) https://pdfa.org/wtpdf/
