Build status for branch 'master': 
This library is available on Nuget as Imazen.WebP.
This library offers P/Invoke exposure for webp/decode.h and webp/encode.h, but not demux.h and mux.h.
new Imazen.WebP.SimpleDecoder().DecodeFromBytes(byte[] data, long length)->System.Drawing.Bitmapnew Imazen.WebP.SimpleEncoder().Encode(Bitmap from, Stream to, float quality)Imazen.WebP.SimpleEncoder.GetEncoderVersion() -> String,Imazen.WebP.SimpleDecoder.GetDecoderVersion() -> String
- Expose the power of Imazen.WebP.Extern.WebPConfig and Imazen.WebP.Extern.WebPPreset for better encoding.
- Consider using WebPDecode for better decode error details.
- Animation support
- Make LoadLibrary cross-platform (although it is not strictly neccessary)
- Add .NET Core support. This will likely require introducing a PixelBuffer{width, height, ptr, stride} interface that can wrap System.Drawing.Bitmap via adapter. System.Drawing.Bitmap is currently directly used by the
SimpleDecoderandSimpleEncoderclasses, but these total < 200 lines of code. Or, leave the core API as P/Invoke only. libwebp doesn't have a bad API at all.

You may need vcruntime14 (VS 2015 C++ Redistributable) https://www.microsoft.com/en-us/download/details.aspx?id=48145
This library is binary compatible with as-is NMake builds of libwebp (no custom C/C++).
