I found this interesting note in the article: > HEIC and AVIF can handle larger [than 35MP, 8MP respectively] images but not directly in a single code stream.

I found this interesting note in the article: > HEIC and AVIF can handle larger [than 35MP, 8MP respectively] images but not directly in a single code stream. You must decompose the image into a grid of independently encoded tiles, which could cause discontinuities at the grid boundaries. [demo image follows]. The newest Fujifilm X cameras have HEIC support but also added 40MP sensors--does this mean they are having to split their HEIC outputs into two encoding grids? It seems like the iPhone avoided this, as 48MP output is only available as a "ProRAW" i.e. RAW+JPEG, which previously used regular JPEG and now JPEG-XL, but never HEIC.
