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.

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…

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.

📱 On my way to #Debconf22 and it was the first time I could show the QR code of a train ticket on #phosh's lockscreen to the conductor (had to resort to unlock ➡️ nautilus ➡️ evince so far).

For that I stitched together a lockscren plugin that leverages #evince's libevince. Hope the other tickets will works just as well tomorrow.
