“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!
