WebP library for C#

Take a look at http://webp.codeplex.com/. There is a library that allows you to easily encode into WebP format. Check out this question for more information:

Convert Bitmap to WebP Image?

The library allows you to save into WebP format like so:

using (Image image = Image.FromFile("image.jpg"))
{
   Bitmap bitmap = new Bitmap(image);
   WebPFormat.SaveToFile("image.webp", bitmap);
}

WebP-wrapper

Wrapper for libwebp in C#. The most complete wapper in pure managed C#. Exposes Simple Decoding API, Simple Encoding API, Advanced Encoding API (with stadistis of compresion), Get version library and WebPGetFeatures (info of any WebP file). In the future I´ll update for expose Advanced Decoding API. The wrapper is in safe managed code in one class. No need external dll except libwebp_x86.dll and libwebp_x64.dll (included v6.1). The wrapper work in 32, 64 bit or ANY (auto swith to the apropiate library).

The code is full comented and include simple example for using the wrapper.
