no decreasing in file size after changing resolution of avif image

kornelski commented 9 months ago

This library is a low-level component, and isn't really responsible for image resizing.

If you're changed resolution using Apple's Preview.app, you may have edited DPI metadata instead of changing the image.

ok, thank you.

Oh, I think I know what you mean now: this library takes width and height. These properties are supposed to reflect what the size of AV1 data is, not change it.

See the https://lib.rs/ravif crate for encoding AV1 from scratch.
