Bob, could you please elaborate on the advantages of using Webp inside TIFF, rather than using Webp directly?

TIFF provides a way to store and retrieve attributes via an integer tag. It supports multiple image frames without introducing a wrapper.

Most importantly, WebP is only useful for images with small/medium dimensions. Since TIFF supports strips and tiles and each strip/tile is its own WebP image, many smaller WebP images can make up a very large TIFF image.

It is not difficult for software already supporting TIFF to support WebP-compressed TIFF.

I see that TIFF using WebP compression is advantageous for TIFF users and does not compete with the original intended purpose of WebP.
