“Annotation censoring everywhere”

#Censor, the #PDF document #redaction tool for the #GNOME desktop, got a minor update to v0.7.1. Find it at @flathub: https://flathub.org/apps/page.codeberg.censor.Censor and @Codeberg: https://codeberg.org/censor/Censor

Censor’s #Flatpak package comes with the latest version of the upstream library #PyMuPDF (1.27.2.3). This solves an issue with annotations that could not be redacted in some files. Thanks to Julian Smith from #Artifex for fixing it upstream. In case you do not use the Flatpak package, you may need to wait for your distribution maintainers to update PyMuPDF’s version.

Hindi has been added to the languages you may now speak with Censor. Thanks to the translators!

“Zoom in, zoom out, redact your points!”

#Censor v0.7.0 ships improved zooming with pinch-to-zoom gesture on touchpads and touchscreens and various security bug fixes. Find it at @flathub: https://flathub.org/apps/page.codeberg.censor.Censor and @Codeberg: https://codeberg.org/censor/Censor

You may now redact safely also #PDF documents with cropped, scaled, or rotated pages. The upstream #PyMuPDF library has some issues treating these documents. Thus, I implemented manual transformation and drawing of the redaction rectangles, and verified the proper redaction with a specially created sample document, submitted to the collection by #pypdf: https://github.com/py-pdf/sample-files/pull/36

Additionally, point- or line-like elements are now properly redacted. Sanitization during post-processing keeps now entries in form fields (note: this changes previous behavior).

Thanks to the translators, Censor is now available in 13 languages including Croatian and Russian.

“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!

That said and celebrated ;), there are things that #Censor is not yet well redacting.

The upstream library #MuPDF (with its #Python bindings in #PyMuPDF) supports by default only redaction of text, vector graphics and images. Testing on a variety of PDF files (thanks to #pypdf, #qpdf, #ghostscript, and their issue reporters, as well as @pdfarranger for their hint) let me discover that some vector graphics are not properly redacted and an upstream issue has been reported for that.

Also, form fields (widgets), signatures and links may be incompletely redacted.

You can find an updated list of “What is redacted? What not?” here: https://codeberg.org/censor/Censor/issues/120

“Better safe than sorry”

For release 0.5.0 of #Censor, a lot of work went into improving the security of PDF redaction.

PDF documents are tricky, and irrevocably removing elements from them is even more. With this release, before saving a redacted document, garbage is now properly collected and documents are sanitized, which means that metadata, page thumbnails, etc. are removed.

Also, vector graphics are now removed with a more strict option when they overlap with redaction rectangles. On top of that, I added redaction of PDF annotations.

The user interface was refreshed: with undo and redo buttons in the toolbar and improved document saving experience. Drawing rectangles is now indicated by a crosshair cursor.

Thanks to the translators, you may now talk also Czech with Censor!

“A historic moment for Censor”

#Censor – the PDF redaction tool for the @gnome desktop – comes now with a new edit history. It allows you to undo and redo redactions using the right-click context menu or keyboard shortcuts. Also, a bug that prevented repeated saving to the same file path was fixed.

Get the new version from @flathub: https://flathub.org/apps/page.codeberg.censor.Censor, and find it on @Codeberg: https://codeberg.org/censor/Censor/releases/tag/v0.4.0

You may now talk Chinese, Dutch, English, Estonian, Finnish, French, German, Italian, and Vietnamese with Censor (thanks a lot to the translators!). If your language is missing from this list I invite you to contribute at Codeberg Translate: https://translate.codeberg.org/engage/censor

Once I saved as PDF some emails from my previous job (Outlook). Those PDF come in a weird form factor, it looks they save the email as attachment, but they could also handle the cronological history.

Such "format" isn't read by the #GNU #Linux #PDF readers I usually use: #Atrill, #MuPDF, and #XPDF.

Rather than see the real content I get a slide that invites me to download Acrobat Reader...

Needless to say that not even the web browser and #Inkscape are able to open properly this PDF.

Eventually I had to use Acrobat Pro from my $WORK computer...

Besides being annoying and frustrating how do you ooen, if you suucceded, those bastard PDF with #Opensource software, preferably on GNU/Linux and #BSD?

Thanks... 🙏

Как удалить JavaScript из файлов PDF

Как известно, внутри файлов PDF можно размещать скрипты JavaScript, которые будут запускаться на исполнение в браузере. Например, если загрузить этот PDF , то вы увидите результат выполнения скрипта: Это стандартная функция формата. Все разработчики браузеров знают, что PDF подобно HTML является активным контентом и может содержать исполняемые скрипты.

Hoje recomendei uma app para ler pdf, singela, open source e que está na Play Store (e que procurei de forma rápida): MuPDF Mini.

#app #apps #android #foss #MuPdf #MuPdfMini #pdf

Prinzipiell ist #broot ein feiner Dateimanager für #Linux, aber dessen Dokumentation ist einfach Schrott. Um ihm abzugewöhnen PDFs immer mit #GIMP zu öffnen, habe ich mich mal eingelesen. Aber die Doku fängt schon mit einem Fehler an: dort steht als Beispiel "default_flags: -gh", doch damit erhält man beim Start des Programm nur ein "Unable to parse"-Error, weil das Minus "-" falsch ist. Ohne klappt es. Egal, ob definierte Verzeichnisse nach Datum zu sortieren oder eben PDFs mit #muPDF zu öffnen, alle meine Versuche in verschiedensten Varianten waren erfolglos. Ist natürlich Schade, so ein gutes Programm zu entwickeln und bei der Doku dann derartig zu pfuschen.

Na gut, #vifm und #ranger reichen mir grundsätzlich natürlich ;-)

@mwfc @claudi @dchsg_le Ja, die vernuenftigsten digitalen Tickets kann man einheitlich mit #muPDF darstellen...

Es muesste sich eigentlich mal jemand die Muehe machen, eine Musterklage wegen des Semesterbeitrages zu fuehren. Die einzige schluessige Rechtfertigung dafuer, dass alle Studierenden den #Semesterbeitrag bezahlen muessen, ist, dass alle Studierenden die _Moeglichkeit_ erhalten, davon finanzierte Dienstleistungen zu nutzen. Was wir hier beobachten, ist, dass Beitragszahlende ausgeschlossen werden von der Nutzungsmoeglichkeit. So gesehen ein Dammbruch, was das Prinzip "#Solidarbeitrag" angeht.
