[fr] Ajouter le support du format APNG
[en] Add APNG support
@zyabin101 Oh really? That's a shame :(.
@Sylvhem However, a few people into wikipedia know how to cheat over GIF's strict limit of 256 colors per image 😉
@zyabin101 @Sylvhem About the APNG format, it was seen as redundant when it was released. There exist an older animated format based on PNG, the MNG. So those who already supported the MNG format were reluctant to support the new format made by Mozilla.
Also, the MNG/APNG format are not good for long animations, as they tend to be heavier than GIF. GIF are already heavy for long animations, and as such, mastodon automatically convert them into a video format.
The only point of using APNG over GIF is for getting a real alpha layer and not just a transparent color. However the alpha layer would be lost if converted to a video format.
@Sylvhem APNG is not as widely supported as GIF: Firefox works, Chrome/Opera require an extension to make it work, and Greenfish Icon Editor Pro requires strictly static PNGs. Classy! 🙁
