1709815 - Support progressive decoding for JPEG XL

Status: NEW

(Core :: Graphics: ImageLib, enhancement)

Description

[Kagami Rosylight [:saschanaz] (they/them)]

Currently it renders only after getting the full bytes, but since JXL supports progressive decoding images should be able to be rendered earlier with a lower quality and then get better with more data.

Please, forgive me if it's a dumb question.

Couldn't the browser stops the download when the file reaches the shown resolution, so we could really take advantage of the progressive decoding?

The bug assignee didn't login in Bugzilla in the last 7 months, so the assignee is being reset.

That needs a spec. I think I saw a relevant suggestion somewhere but I don't remember where it was. (Such thing can probably be applied to any progressive format.)
