mahlzahn commented 2026年03月16日 12:51:06 +01:00

Description

Given that there are (and possibly always will be) some insufficient redactions (currently: form fields (widgets), some graphics #134, signatures #98, ...), maybe add warnings for users who want to use Censor for secure redaction.

Context: currently, only (削除) 86-92% (v0.5.0) (削除ここまで) 90-96% (with !151) of test PDF files are redacted properly, see #110!

Implementation

• Generally warn about the limits of Censor
  • from time to time or at first opening or at first opening after an update?
  • in the application description on Flathub (in appstream data
  • in the about dialog or potentially in a help page?
• If a document cannot be opened or saved
• Detect insufficient redaction
  • after opening a document
    • try full page redaction !124 and verify that it works, else warn user that redactions in this document may not be secure
    • or/and check if document contains non-redactable elements
  • after saving a document with redactions
    • check if all rectangles from remaining graphics do not overlap with redactions, else warn user that some graphics redactions may not have been applied properly
    • check for hidden text?
