Convert from WebP?

[binarykitchen]

Hello there

In your examples I do not see if the module is able to convert from WebP to another format like JPEG?

Can you add such an example or at least state that this is not possible?

Thx!

Hi!

This module is a wrapper around cwebp utility for compressing images to WebP format.

To decompress images back you should use dwebp instead.

Right now node-webp supports only cwebp. Though, It's not very difficult to extend it to support dwebp as well.

thanks - yes, dwebp support would be great! do you think you could add that?

I'm extremely busy right now, but I'll try to find time to implement it.

Meanwhile, you may hack node-webp by changing Webp.bin from cwebp to dwebp:

CWebp = require('cwebp');

function DWebp (source, bin) {
  CWebp.constructor.call(this, source, bin)
}

DWebp.bin = 'dwebp';
DWebp.verbose = false;

Promise.prototype.__proto__ = DWebp.prototype;

But you won't be able to use node-webp build-in methods with this new class, only raw command method.

@binarykitchen just realized that you can specify binPath in a constructor:

var Webp = require('cwebp');
var dwebp = new Webp(source, 'dwebp');

It's much simpler. But build-in methods won't work without proper dwebp support, anyway.

thanks for the comment but i think i rather wait - take your time

I started working on dwebp support.

The most difficult problem I'm facing right now is to decide whether I should rename this project on npm or not.

On the one hand, it will no longer be cwebp, because it'll support other webp utils.
On the other hand, it may confuse node-webp users.

Any ideas?

Another problem with renaming the project is that all good webp-related names are already taken.

why not have a fantasy name but mention webp under keywords + description in the package.json?
