Interface: SharpenEffect

Defined in: attributes/shape/effects/implementations/sharpen.ts:15

Unsharp mask — the standard sharpen: subtract a blurred copy of the content from itself and add the difference back, which exaggerates local contrast at edges.

out = c + amount · (c − blur(c, radius))

radius sets the scale of detail affected (a small radius crisps fine texture, a large one adds "clarity" to broad shapes); amount sets how hard. Past ~2 the classic halo artefact shows up, which is sometimes the point.
