- * @param {Number} [size] The size of the pool. Defaults to the number of CPUs

- * decoding will be done in the main thread.
- * @param {function(): Worker} [createWorker] A function that creates the decoder worker.
- * Defaults to a worker with all decoders that ship with geotiff.js. The `createWorker()`
- * function is expected to return a `Worker` compatible with Web Workers. For code that
- * runs in Node, [web-worker](https://www.npmjs.com/package/web-worker) is a good choice.
- *
- * A worker that uses a custom lzw decoder would look like this `my-custom-worker.js` file:
- * ```js
- * import { addDecoder, getDecoder } from 'geotiff';
- * addDecoder(5, () => import ('./my-custom-lzw').then((m) => m.default));
- * self.addEventListener('message', async (e) => {
- * const { id, fileDirectory, buffer } = e.data;
- * const decoder = await getDecoder(fileDirectory);
- * const decoded = await decoder.decode(fileDirectory, buffer);
- * self.postMessage({ decoded, id }, [decoded]);
- * });
- * ```
- * The way the above code is built into a worker by the `createWorker()` function
- * depends on the used bundler. For most bundlers, something like this will work:
- * ```js
- * function createWorker() {
- * return new Worker(new URL('./my-custom-worker.js', import.meta.url));
- * }
- * ```
