Implement streams as with node-canvas

[GreenFlag31]

Hi.

Your solution has been choosed as replacement for pdfjs-dist of node-canvas. However, it does not implement streams (nodejs) as with node canvas : see here.
Implementing streams improves memory consumption and is not slower according to my tests (tested to convert a PDF into an image with/without streams).

Would it be something you could consider?

I know its not technically the same, but I'm using this as a quick patch.

import { Readable } from 'stream';

import { createCanvas } from "@napi-rs/canvas";

const canvas = createCanvas(100, 100);

const canvasStream = Readable.from(canvas.toBuffer('image/png'));

Yep, this is possible, but this is like paying 2 times to cost of rendering. canvas.toBuffer(...) already has a cost. If you wrap it inside a stream, it means paying 2 times to cost of rendering. The goal is to use a stream instead of canvas.toBuffer().
