PDF/UA-2, WTPDF
by Henning Hraban Ramm 20 Sep '24

20 Sep '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/

Table and rotation: push together 45 degree rotated cells
by Gerion Entrup 19 Sep '24

19 Sep '24

Hi, I want to typeset a table where some of the column headings are really long, while in the columns itself consists only of numbers. Therefore, my idea was to rotate the column headings but not 90 degrees (I found some solutions for that) but 45 degree. It then would be beneficial to push together the rotated cells, so the text of one cell actually starts above the previous cell. Do you know, how to achieve that? Here is a minimal example: ``` \startsetups[table:rotated] \setupTABLE[frame=off] \setupTABLE[row][first][bottomframe=on, style=bf, align={center, low}] \setupTABLE[row][2][align=flushright] \stopsetups \starttext \define\tablerotate{\dontleavehmode\rotate[rotation=-45, location=high]} \bTABLE[setups=table:rotated] \bTR \bTD \eTD \bTD \tablerotate{Water buffalo} \eTD \bTD \tablerotate{Mexican redknee tarantula} \eTD \bTD \tablerotate{European turtle dove} \eTD \eTR \bTR \bTD Amount of legs \eTD \bTD \digits{4} \eTD \bTD \digits{8} \eTD \bTD \digits{2} \eTD \eTR \eTABLE \stoptext ``` I would like to achieve that the text "Mexican redknee tarantula" is typeset right and above of "Water buffalo" so that the single columns have a width that is similar to the width of the single digit coming in the second row. Another question in this context: Is is possible to specify a \setupTABLE command that works for column 2-4 starting from row 2? Something like \setupTABLE[row][2-][column][2,3,4][background=color, backgroundcolor=red]. In this example this would cover all numbers but nothing else. Best Gerion

Paste something into https://text.makeup/ and let it explain how an emoji is constructed, what the escaping means etc. You can find examples in the left sidebar. Have fun! HR

Inline equations and html export
by Florent Michel 18 Sep '24

18 Sep '24

Hello, Thanks Hans and everyone who has worked on it for the new upload! I have noticed a change which seems to break XML/html export for inline equations; although I don't know if the issue is with the new version or with how I'm using it. Minimal example: ``` \setupbackend[export=yes] \setupexport[alternative=html] \starttext $1 + 1 = 2$ \stoptext ``` When compiling with ConTeXt 2024.09.17 and opening either the `.html` or `.xhtml` file with Firefox or Chromium, the positions of the 2 and = sign are reversed, while the equation is correctly rendered when using ConTeXt 2024.08.16. The (I think) relevant part of the html code generated by ConTeXt 2024.09.17: ``` <div> <math data-lmtx-blob="1" display="inline" displaystyle="false" xmlns=" http://www.w3.org/1998/Math/MathML"><mrow><mn>1</mn><mo mathcharacter="43" mathclass="binary" mathgroup="everygroup" mathindex="43">+</mo><mn>12</mn></mrow></math>=</div> ``` Code generated by ConTeXt 2024.08.16: ``` <div> <math data-lmtx-blob="1" data-lmtx-meaning="1 plus 1 equals 2" display="inline" displaystyle="false" xmlns=" http://www.w3.org/1998/Math/MathML "><mrow><mn>1</mn><mo>+</mo><mn>1</mn><mo>=</mo><mn>2</mn></mrow></math></div> ``` Am I doing something wrong here, or is html export for inline equations not currently supported? Best regards, Florent

any way to show downloading progress for the `install.sh`?
by hf＠hongfeng.ch 18 Sep '24

18 Sep '24

for the installation of ConTeXt, when the shell script `install.sh` start to run, any way to show the downloading progress when it fetches the zip from the site? For example: ``` mtx-install | fetching 'http://lmtx.pragma-ade.com/install-lmtx//texmf.zip' ``` It looks stopped while the downloading is going on. but the user may wrongly regard something goes wrong When the networking speed is slow. Two options would be nice: a) just how the current percentage of the downloaded data; b) even better, under the line, starting a new line, starting with a percentage, then followed by dash characters plus an arrow like `->` to show the downloading progress dynamically --- while the downloaded data adding up, the number of dash characters prolongs accordingly.

Hello, basically my question is to know if there is a way to use ConTeXt to perform the functions that pdfcrop does. pdfcrop: A Perl script that can either trim pages of any whitespace border, or trim them of a fixed border

(ConTeXt LMTX 2.11.05) how do I make it so that sections, descriptions, and itemizations have just a space between some of the text that they produce
by Felix 16 Sep '24

16 Sep '24

\setuppapersize[letter][letter] \setupalign[normal] \setuplayout[ backspace=0.5in, topspace=0.0in, header=.5in, % No headers footer=.5in, % Space for the footer width=middle, height=middle, ] \definefontfeature[timesfeatures][default][ trep=yes, % Enables single and double quotes to show up correctly in text, perhaps does more dlig=yes, % cpsp=yes, use for all caps only ] \definefontfamily [myfonts] [rm] [Times New Roman] [features=timesfeatures] % dlig enables times new roman ligatures, and cpsp is used by tnr, not aptos \setupbodyfont[myfonts,12pt] \mainlanguage[en-us] \setupindenting[yes,0.5in] \definedescription[description] \setupdescription[description][ alternative=serried, headstyle=bold, style=normal, width=broad, before=, after=, ] \setupheads[indentnext=yes] % To get indentation after section numbers, use this \setuphead[section][ sectionstopper={.}, % Add period after numbers conversion=R, before=, after=, style=sc, % Small caps style align=middle, % Center the section titles ] \startsetups document:start \centerline{\documentvariable{title}} \centerline{\documentvariable{author}} \centerline{\documentvariable{date}} \blank[line] \stopsetups \startdocument[ title={Chapter 4 Quiz}, author={Author}, date={September 16, 2024} ] \startitemgroup[itemize][n] \startitem I'm not a fan of the default spacing \stopitem \stopitemgroup \startdescription{I'm not a fan of the} default spacing \stopdescription \startsection[title={I'm not a fan of the}] default spacing \stopsection \stopdocument This code shows how I am getting the default spacing between the words from itemize, description, and the spacing between the roman numeral and the section title. I tried figuring out how to get the spacing for all of these to be set to a single space worth but it seems to not be possible with `distance`, because it asks for a dimension. How can I get a `\space`'s worth of spacing to be the default in descriptions, itemizations, and sections? for itemizations and descriptions the spacing seems to vary and I really don't like that. I would be thankful to know if there's a way to change the spacing.
