redact annots can not remove overlap contents

[marc-chin]

hi there,

i tried to use the below code to remove the contents in my pdf document, add redact annot can mask the content(drawing), but once i use adobe PDF pro DC to edit the document(Touch up tool ), after delete the redact annot, the drawing appeal again, which mean the redact annot can not remove the contents completely, right?

rect=fitz.Rect(2,2,200,27)
page.wrap_contents()
page.add_redact_annot(rect,text='xxxxxx',fill=None)
page.apply_redactions(images=1)

doc.scrub(redactions=True,redact_images=2)
doc.save('removelogo.pdf',garbage=3)

how can remove the contents in the document completely?

You are right:
The redaction logic only removes

• links that overlap a redact rect
• text characters whose (somewhat reduced) bbox overlaps a redact rect
• images ...
  • either completely if overlapping a redact rect and fitz.PDF_REDACT_IMAGE_REMOVE is specified,
  • or not at all if fitz.PDF_REDACT_IMAGE_NONE is specified,
  • or the overlapping part if fitz.PDF_REDACT_IMAGE_PIXELS is specified.

Other overlapping objects, e.g. drawings, remain untouched - there is no way out.
