Hi, thanks for the PR! This is a good improvement, but I think I'd rather have this optimisation upstreamed to ecolor so that we can keep using their implementation and avoid adding other dependencies (even though quite a lightweight one). How do you feel about contributing this directly to Egui's ecolor instead?

Btw, even 33ms looks like a lot.. What's the size of the image you are trying to update? This made me think whether offloading the conversion to a separate task pool would make sense. (Not sure it would make any difference in WASM though...)

Or we can look into implementing a partial image update if that can help in your scenario.

Hello, I’m not very familiar with egui, but I can give it a try.

I’m developing a card game where individual images aren’t very large, but there might be a lot of images and fonts created all at once.
