This repository contains a Windows Runtime Component that wraps up libwebp and allows to decode static and animated WEBP images.
The code is released under the MIT/X11, so feel free to modify and share your changes with the world.
You can use WebPImage.DecodeFromByteArray method to get a WriteableBitmap directly from a static WEBP.
If you want to decode an animated WEBP (or you need to decode both) you can use instead WebPImage.CreateFromByteArray.
This method returns a reference to a WebPImage object instance that exposes an array of WebPFrames via its Frames property.
You can simply loop the collection and get a WriteableBitmap from every frame using its RenderFrame method.
You can install the library via NuGet.
