This library doesn't allow for configuring some decoders that take extra parameters. The line above shows this explicitly where only one argument is given instead of at least another options object. Decoders such as the jpeg-js one offer extra configurations in the form of another configuration that can be useful for a given context (see here google/eleventy-high-performance-blog#10).

My proposal fix would be to change the constructor function to allow an decoderOptions key that map mimetypes to the respective decoder options. For example:

const decoderOptions = {
  "image/jpeg": {
    maxMemoryUsageInMB: 1024,
  }
};
Jimp.decode({ path: "filepath.jpg", decoderOptions, });
Jimp.decode("filepath.jpg", { decoderOptions }); // alternative
