scanify --aggressive --bent --dusty document.pdf| Option | Description |
|---|---|
--aggressive |
Apply stronger scan effects (more noise, rotation, artifacts) |
--bent |
Add paper bend shadow effect (like curved paper under a scanner) |
--dusty |
Add random dust specks and hair particles (like a dirty scanner glass) |

| Effect | Description |
|---|---|
| Paper darkening | Whites become slightly gray (scanned paper is never pure white) |
| Edge shadows | Vignette effect from scanner lid |
| Top shadow | Gradient shadow at top edge |
| Uneven lighting | Slightly off-center lighting variation |
| Noise/grain | Paper texture simulation |
| Slight blur | Optical imperfection |
| Random rotation | Paper feed misalignment |
| Saturation reduction | Scanner color limitations |
Amplifies all base effects for a more dramatic scan appearance:
- Stronger rotation (up to 1.5°)
- More noise and grain
- Heavier paper darkening
- More pronounced edge shadows
Adds a horizontal shadow band across the page to simulate paper that isn't perfectly flat on the scanner glass.
Adds random artifacts to simulate a dirty scanner:
- 15-40 dust specks of varying sizes
- 0-3 thin hair/fiber lines
- Randomly scattered (not uniform)
