디더링

Uses a dot pattern to represent tones with fewer colors, creating a dithering effect.

It turns continuous tones into the density of small dots. Like newspaper print or an old low-color display, the dots merge into a tone when seen from a distance.

The default `pattern` is `bayer4`; it selects the dithering pattern. `pixelSize` defaults to 4 and ranges from 1 to 20, while `threshold` defaults to 0.5 and ranges from 0 to 1 to set dot size and the brightness boundary. `spread` defaults to 1 and ranges from 0 to 1 to set the tonal range; lowering it creates more solid areas. The default `colorMode` is `custom`.

Place it over an image or video layer. Pair it with `Halftone` for a stronger print look, or use `Pixelate` to make the grid larger. The dots can distract when a smooth gradient needs to remain visible as-is.

When to use

Use it for low-color pixel graphics, print-inspired posters, and icons with simplified tones. Avoid it when smooth color transitions are central to the image.
