Are there any plans to add support for the AVIF image format?
This format seems to be in its infancy, not well-defined, but I a impressed that I can save an image from Zoner Photo Studio (ZPS)—which is the main program that I use for image editing—in 12-bit lossless AVIF format, and have it often come out smaller, and very rarely any larger, than a 24-bit lossy JPG with 95% quality.
As I said, though, it doesn’t seem well-defined, yet, and not widely or consistently supported. I have discovered, for example, that between ZPS and GIMP, if I save an image from one of these programs in AVIF format, the other program usually cannot read it.
