[v2] apply quality without resizing #26

Closed tanc closed 3 years ago

tanc commented 3 years ago

The nuxt image module uses ipx to provide the image processing endpoint and it passes through a quality option like q=65 in the url. From what I can tell this is ignored at the ipx end. Is it possible to use this to tell sharp to resize/process at a specific quality level?

Looking through the code there does seem to be a q option but in my tests it didn't change the file size at all: https://github.com/nuxt/image/issues/184

Hi dear @tanc. Actually there is quality support but you need to provide dimensions (width and/or height) in order to make it applied. BTW both ipx and image module are WIP so this is expected.

@pi0 thanks for responding! No problem, I understand its in beta, I just wanted to report findings so that things can be worked out and improved!

Just to be sure, is it supposed to work (resizing) in develop mode? I'm trying width and height with quality like this:

http://localhost:3000/_ipx/images/rich.jpg?f=jpeg&q=95&w=1000&h=1000

The results are always the same file size when I vary the value of q.

Hi @tanc. Quality handling fixed in ipx 0.6.0 / image 0.4.0.
