Aha! I figured it out, closing. I had to set createCanvas
:
const pica = (await import('https://esm.sh/pica')).default({ createCanvas: (w, h) => new OffscreenCanvas(w, h) })
const b = await pica.resize(from, to, options).then(r => pica.toBlob(r, mimeType, quality))
from pica.
If I try to do it manually, I get LinkError: WebAssembly.Instance(): Import #0 "env" "memory": memory import must be a WebAssembly.Memory object
:
const { file, size, options, mimeType, quality } = event.data
const u = URL.createObjectURL(file)
const from = await createImageBitmap(await fetch(u).then(r => r.blob()))
URL.revokeObjectURL(u)
const pica = (await import('https://esm.sh/pica')).default()
const ctx = (new OffscreenCanvas(from.width, from.height)).getContext('2d')
ctx.drawImage(from, 0, 0)
const src = new Uint8Array(ctx.getImageData(0, 0, from.width, from.height).data)
const b = await pica.resizeBuffer({ src, toWidth: size[0], toHeight: size[1], quality, ...options })
console.log(b)
from pica.
