Xamarin iOS / Mac bindings for WebP decoding NuGet package can be found here: https://www.nuget.org/packages/WebP.Touch
Original WebP framework comes from http://downloads.webmproject.org/releases/webp/index.html Content is extracted from the framework and bindings are created for the native libraries. Currently we use libwebp-1.0.3 from SDWebImage (https://github.com/SDWebImage/libwebp-Xcode)
This project is used to expose some simple methods to use the original WebP.framework At the moment it will only expose methods for decoding
Some inspiration came from WebP decoding project from Sean Ooi https://github.com/seanooi/iOS-WebP
