My mistake.... I have been duped by a Jpeg XR demo which also uses javascript for image rendering.
Effectively, there's only IE supports for JXR, so it's worst than WebP.
I want to avoid PNG because of the poor compression quality and efficiency in lossy mode, and the big file size in lossless mode.
And I'm looking for a format supporting a good compression ratio and alpha channel at the same time.
I also tried BPG but i think it's too young and the compression times are really too slow... And there's no Magick support at all.
I think I'll stick with WebP and JS decoder.
Thanks.
