#poppler — Public Fediverse posts

More efficient every day: #Poppler, the #PDF engine used by #Okular, gets the KDE treatment and can now generate documents with embedded forms that can be more than 10 times smaller thanks to a technique called _subsetting_. Watch the video to see how this works.

This feature was implemented by Ojas Maheshwari's during their KDE Google Summer of Code stint.

The #OpenAI #Codex desktop app (since rebranded to just #ChatGPT ) has 1.7GB of stuff in there in a folder called codex-primary-runtime, including a full #Python installation, a full #NodeJS installation, and native binaries for #Poppler, git, and the #LibreOffice open source office suite

#Debian LTS contributors released 52 DLAs fixing 2159 CVEs in July. Notable security updates were released for the #linux kernel, grub2, imagemagick, jq, nginx, nss, poppler, samba and more.

Debian LTS team took full responsibility of Debian 12 (#bookworm) in July after its last point release.

Debian LTS contributors also prepared updates for the stable release, Debian 13 (#trixie).

And now it is better implemented without without hacks. Screenshot unchanged.
Brotli-support in #poppler (and thus #KDE #Okular #evince #gnome #papers and others) will work when merged (hopefully in next Poppler release)

Apparently, zlib compression in PDF's aren't good enough any longer so new documents might be Brotli-compressed instead. Not many readers implement it yet, so we better get hacking.

This is built with bubblegum and duct tape.

Encountered a #Poppler bug report with an attached sample PDF document that takes over 45 seconds to render its first page on my fastest computer, so I took the opportunity to profile it with #Sysprof : https://gitlab.freedesktop.org/poppler/poppler/-/work_items/1572#note_3592829

#PDF #performance #profiling

Oh wow. Someone found a way to speed up image rendering by ~32x (or more?) in the Poppler PDF library, and their solution sat in this comment thread because they're unable to fork the repository 😬

That's quite unfortunate. I wonder what prevents guest users from forking on the #FreeDesktop GitLab instance?

Невидимый слой PDF с инструкциями для ботов

Невидимый текстовый слой PDF можно редактировать и экспортировать в Markdown, JSON и TXT. Такие документы называются адаптивными PDF , они созданы для чтения и людьми, и роботами. Люди видят обычный PDF, а роботы — отдельный слой ActualText с текстом в Markdown и картинками в base64.

“Secure #redaction by design and through extensive #testing”

#Censor 0.6.0 comes with many more #security improvements, motivated by extensive testing on more then 1,000 #PDF document samples. You may now redact securely also links, form fields and widgets. In rare cases, when partial image redaction fails, the more secure full image removal is used instead.

But even more important, Censor now warns you, when unsuccessful redaction is detected during postprocessing. This reduces the impact of known issues of unsecure redaction.

Polish is the 11th language you may speak with Censor. Thanks to its translators (among them, @mondstern)!

Thanks a lot also to #pypdf, #qpdf, #pikepdf, #Ghostscript, #MuPDF, #PyMuPDF, and #poppler contributors for the great resource of PDF document samples!

My problem is not the computer (hardware) that is broken. My problem is the software that is broken.

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 :owi:

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

So on my laptop there's a program called "poppler" that has updates every few months. It came with the Linux Mint installation and I don't think I've ever gone out of my way to use it.

I keep it installed because every time the name comes up in the update manager I'm reminded of Futurama and smile.

#Linux #LinuxMint #Futurama #Poppler

To find out what fonts are used by a #PDF, you can use, e.g., the "pdffonts" command that comes with #Poppler (in #Debian and Debian-based systems it's in the "poppler-utils" package).

Update:
If I import in #Inkscape with #poppler/#cairo library, the qrcode it's importer and working BUT I lose the multipage import 😞

Maybe @doctormo you have some suggestion about that?

Am really enjoying using Julia as a pseudo-shell.

I needed to chop up some pdfs and rearrange the pages. Poppler-utils is great but I never really learnt Bash scripting so it was going to be a bit of a slog.

Thankfully, Julia makes it really easy to bulk copy or move files in mostly regular sequences

pop a #Poppler in your mouth when you come to Fishy Joe's, what they're made of is a mystery, where they come from no one knows.

You can pick 'em, you can lick 'em, you can chew 'em, you can stick 'em, if you promise not to sue us, you can shove one up your nose.

@jsoriano Please don't thank me (dreua) specifically, I'm just one part of the maintenance team who runs this account 😉

We currently don't accept donations (don't really need them) but @tsdgeos mentioned in his talk about poppler (one of the great libraries PDF Arranger is built upon) that they could use some resources for testing in #poppler or #freedesktop .

Words of appreciation are, of course, always welcome. Thank you ❤️

@tsdgeos Thanks for the cool talk and thanks to you and all the maintainers of #poppler! Our small desktop app is truly standing on the shoulders of giants :)

If anyone from the people who offered us donations is reading this: Sounds like Freedesktop and Poppler could put your money to good use 😉

Long-time KDE developer Albert Astals Cid @tsdgeos is also maintainer of the PDF renderer Poppler and has given a nice lightning talk on #FOSDEM 2025 about this project:

https://fosdem.org/2025/schedule/event/fosdem-2025-6000-poppler-the-pdf-rendering-library/

By the way, at OpenPrinting we use Poppler a lot (thanks a lot, Albert), but we are working on alternatives to avoid C++ and also because of the license.

@timbosteron Best you use pdfimages from #poppler-tools to extract the original images embedded in the PDF file. So no loss ocurs from conversions 😇 ...

@AndiBarth Same on Fedora. I'd say this is likely a bug in evince (maybe #poppler), have you looked for open bugs or reported it?

Fifefox and Okular can zoom in as expected. I'd suggest the latter because Firefox needs quite some time to render these complex PDFs.
