After 1.5 years in the making, @gnome Papers 50 will let you create freestanding text & ink annotations on PDFs (using a Wacom tablet stylus, for example), i.e. drawing & handwriting (to circle things or sign documents the old-fashioned way, or highlighting on scanned documents): https://lbaudin.pages.gitlab.gnome.org/blog/posts/drawing-writing-with-papers/

Used it in practice today. I've been hoping for this for about 20 years.
Papers nightly is such a massive improvement!

Thank you @lbaudin for implementing it 

#GNOMEPapers #PDF #Poppler

I stumbled upon a 2300-pages-long PDF document that actually is a fantastic benchmark for slow search performance (1.5 to 5 minutes) in most PDF readers (including GNOME Papers, Evince and Okular)… so I fired up #Sysprof through GNOME Builder to measure the slowness, and reported my findings in #Poppler for all of you performance optimization aficionados: https://gitlab.freedesktop.org/poppler/poppler/-/issues/1660

As I'm doing magazine-style brochure design with #Scribus again lately, I thought I'd report this long-standing #Evince issue in #GNOMEPapers : layout metadata not being respected when opening #PDF documents that explicitly specify they should be viewed as booklets.

Currently, anyone in GNOME receiving a fancy PDF from me would need to intuitively know that they are not meant to be displayed as single pages!

Je sais pas vous, mais moi #GnomePapers ne m'a pas convaincu par rapport à #Evince.

Gnome Papers semble plutôt joli, mais je préfère largement la réactivité que j'ai avec Evince, autant au démarrage qu'à l'utilisation.

#GNOME

If anyone is able to crash #GNOMEPapers Nightly by editing the opened PDF with an external app (ex: Paper Clip), *and* can somehow make that happen under gdb or coredumpctl, please share your backtrace, because I am unable to catch this heisenbug while running with GDB or on machines where systemd-coredump is installed: https://gitlab.gnome.org/GNOME/Incubator/papers/-/issues/353#note_2359761

#GNOME

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: https://gitlab.freedesktop.org/poppler/poppler/-/issues/1555

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.

Wow, #GNOMEPapers Nightly now has luminosity-based colour inversion for its night mode, preserving the general hue of colours!

Now comes the tricky part: having the ability to not invert images at all, particularly for photographic content: https://gitlab.gnome.org/GNOME/Incubator/papers/-/issues/319

#GNOME #PDF #darkmode

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: https://gitlab.gnome.org/GNOME/Incubator/papers/-/issues/236
