Usage

import { createWeaveImageClient } from '@jiujue/weave-adapter-worker-image'

const client = createWeaveImageClient({
	width: 794,
	height: 1123,
	dpr: 2,
	clearColor: '#ffffff',
	scene,
})

const r = await client.render()
const blob = new Blob([r.data], { type: r.mime })
const url = URL.createObjectURL(blob)

Composition (Typical Usage)

• Reports/Exports/Thumbnails: This package (PNG binary) + business side converting ArrayBuffer to Blob/Download/Upload.
• Interactive Canvas: Use @jiujue/weave-app (it draws results to a canvas instead of exporting PNG).
