===SUMMARY=== libwebp-sharp is a simple managed warpper around Googles WebP image decoding and encoding library libwebp.

===FEATURES=== Currently libwebp-sharp can only decode WebP image files into the RGB, RGBA, BGR and BGRA format. YUV is currently not implemented. It can return a byte array with the raw image data or a Bitmap object so you direct display the image.

===HOW TO USE=== Simply download the precompiled binaries to start. The download also contains a dynamic build of libwebp.dll (x86) so you don't need any additional software.

Load a WebP image into a Picturebox: LibwebpSharp.WebPDecoder dec = new LibwebpSharp.WebPDecoder(); PictureBox1.Image = dec.DecodeBGRA(@"X:\PATH\TO\YOUR\IMAGE.webp");

Check if WebP header is valid and get image width and height: int width; // e.g 100 int height; // e.g 100 LibwebpSharp.WebPDecoder dec = new LibwebpSharp.WebPDecoder(); bool result = dec.GetInfo(@"X:\PATH\TO\YOUR\IMAGE.webp", out width, out height); // e.g true

Get WebP decoder version: LibwebpSharp.WebPDecoder dec = new LibwebpSharp.WebPDecoder(); string version = string version = dec.GetDecoderVersion(); // e.g. 0.1.2

===SPECIAL NOTES=== A Bitmap object use the BGR or BGRA format, so if you display the Bitmap in a picturebox red and blue are mixed up.

===TODO=== Implement YUV decoding und the whole encoding functions.
