Imports

import { hatchParallel, hatchCross, hatch, type ParallelHatchOptions } from 'pattapatta'
// or from 'pattapatta/hatch'

hatchParallel(path, options?: ParallelHatchOptions) → Segment[]

Option	Default	Meaning
angle	π/4	Line direction (radians)
spacing	0.15	Perpendicular spacing
count	auto	Line count; omit to cover the whole path AABB
length	bbox diagonal	Pre-clip half-length
center	bbox center	Field center

hatchCross(path, options?)

Two perpendicular parallel fields.

Examples

Parallel

const strokes = hatchParallel(createRect(15, 15, 70, 70), {
  spacing: 6, angle: Math.PI / 4,
})

Cross

const strokes = hatchCross(createRect(15, 15, 70, 70), { spacing: 8 })

Serialize with toSvg(group(segmentsToOpenPaths(strokes))).
