topic: webp
10 modules sharing the webp name family (derived from the tree's prefix discipline).
The 'webp' topic family in the Nishi sovereign ecosystem provides tools for handling WebP images within the NishiLang framework, supporting both lossy and lossless compression. The nx_webp module manages the WebP container and VP8L decoding, while nx_webp_alpha extends this with VP8X and alpha channel support. nx_webp_decode serves as the core decoder, building from the first byte, ensuring robustness and compliance with the format's specifications.
