feat: "secure" export to PDF with rasterized images #111

mahlzahn commented 2026年03月03日 19:11:15 +01:00

Description

Although, rasterized export is not and won't be Censor's core functionality, it maybe added as paranoid saving option without the issues of #5.

This export option should also remove all metadata (Edit: Censor does this anyhow since !140 in v0.5.0).

Implementation

• UI: add a menu entry Save Rasterized As... (enabled even without added redactions)
• Backend:
  1. apply redactions (PyMuPDF)
  2. extract page pixmaps
  3. create new document and add PNG images at certain resolution (e.g., 300 DPI) as pages
  4. save this document

Workaround

1. Use Censor and save normally
2. Use ghostscript to convert document
