How it works
Each pixel is compared with a threshold matrix tiled across the image. Fast, parallel and deliberately textured.
| 0 | 2 |
| 3 | 1 |
- A 2×2 matrix of 4 ranks is tiled across the image; a pixel turns white when its brightness exceeds the threshold at its position.
- That gives 5 distinct gray levels, each reproduced by a fixed dot pattern.
