APNG at a glance
APNG
APNG started as a Mozilla-driven attempt to bring better animation into the PNG ecosystem. Its practical relevance increased once modern browsers and toolchains treated it as a viable web animation target.
X3F at a glance
X3F
Sigma raw support is closely tied to the company's Foveon sensor story, giving X3F a reputation and workflow profile that differ from more mainstream Bayer-centric raw ecosystems.
