π Tips & Best Practices
| Problem | Cause | Solution |
|---------|-------|----------|
| Watermark still visible | Position/size doesn't match detection thresholds | Adjust --x-threshold, --min-w/max-w, --min-h/max-h |
Watermark still visible after adjustment | Watermark may be text-based, not image-based | This skill only handles image watermarks; for text watermarks, use redaction or content stream editing |
| Other images accidentally removed | Detection thresholds too broad | Narrow the width/height/position ranges |
| Black/white rectangle appears | Old approach used image replacement instead of content stream deletion | This skill uses content stream deletion β this should not happen |
