New hardcore #PDF rendering performance benchmark for #Poppler:
"Jesus Christ it's a #Lyon (map), get in the car!" 
That map takes 26 seconds to render with Poppler on #Linux, but only 6 seconds with PDFjs, or 15 seconds with XPDF: gitlab.freedesktop.org/poppler…
I've profiled the issue on the various Poppler rendering backends, and there are some hypotheses about the slowness. If anyone can help fix this, that would be fantastic.

Very slow rendering of the Lyon public transit map with lots of vector shapes (#1555) · Issues · poppler / poppler · GitLab
Hi! I have encountered a single-page PDF file that takes a very long time (over 25 seconds on my old desktop workstation) to render with any Poppler-based PDF...GitLab
#GNOME Papers finally becomes a PDF viewer that can digitally sign documents and verify signatures.
The latter was implemented by Marek Kašík from our team. It was several years in the making. He originally implemented it for Evince, but Evince is pretty much dead and it's been waiting to be merged upstream for 1.5 years. When Papers were forked from Evince, Marek rewrote it in #Rust and implemented it there. It's currently under review and should be merged soon. ✌️

I've always envied Adobe Reader/Acrobat users and tablet apps users who have forever been able to freely write on PDFs as if they are physical sheets of papers. Yes, you can use #Xournal++, but I want it as a streamlined UX built into my day-to-day #GNOME PDF reader app.
Although it was not implemented in #Evince, the #Poppler library has some support for ink-like handwritten #PDF annotations.
I have now put together usecases & broad ideas into this #GNOMEPapers ticket: gitlab.gnome.org/GNOME/Incubat…
More ISO standards on PDF accessibility are now available for free!
Today the @PDFassociation announced they are making three additional ISO standards - ISO 14289-1 (PDF/UA-1), ISO 14289-2 (PDF/UA-2) and ISO TS 32005 - available for download at no cost.
Big kudos to the PDF Association and to the following companies for making this possible: Allyant, Axes4, CDP Communications, and TargetStream Technologies.

Today I discovered a new PDF reader, that I think folks doing research will like a lot.
It's called Sioyek [^1] and it's something of a software for power users. It minimal, with VIM style key bindings and hidden keyboard shortcuts. The website shows a great deal of the cool features, I will just mention a very nice addition I'm enjoying.
You can right click a reference in the document, and a small rectangle overlay will show you the linked content without moving your current view, so you do not lose track of where you started.
It's very useful to peek at an equation or a citation and keep reading afterwards.

"Making a positive change: PDF to HTML
The Government Digital Service (GDS) states “Compared with HTML content, information published in a PDF is harder to find, use and maintain”."
Consider the needs of the people you are publishing the information for. Engage with them early to explore alternative options that may better meet their needs.

I know it is not going to resonate much with people in English speaking countries, but this has been a major issue for people who use alphabets with special characters (my native Czech included).
For years #PDF viewers on #Linux such as #Evince couldn't save characters outside the basic charsets in PDF forms. It turned out to be a complex problem and multi-year effort, but it's finally done and you can use unicode in PDF forms. First available in #Fedora 37 where we've already backported it.
Just found out that the open source Python library for converting webpages to PDF, Weasyprint, has recently added experimental support for creating tagged PDFs that conform with PDF/UA:

This is really exciting as there aren’t many open source options for doing this. I’m going to have a play and try creating an @eleventy plugin for this!
