Redact (Rectangle ROI)

Anonymize-mode only. Draw a rectangle to mask burned-in PHI.

The Redact tool is visible only in Anon mode. Drag a rectangle anywhere on the image — on export, the pixels inside are set to zero (or to the configured fill value).

Caution Redactions are committed on export. Until then they are previewed as overlays and can be removed via the Annotations or Anonymize panels.
