Function WebPEncode

pub unsafe extern "C" fn WebPEncode(
    config: *const WebPConfig,
    picture: *mut WebPPicture,
) -> c_int

Main encoding call, after config and picture have been initialized. picture must be less than 16384x16384 in dimension (cf WEBP_MAX_DIMENSION), and the config object must be a valid one. Returns false in case of error, true otherwise. In case of error, picture->error_code is updated accordingly. picture can hold the source samples in both YUV(A) or ARGB input, depending on the value of picture->use_argb. It is highly recommended to use the former for lossy encoding, and the latter for lossless encoding (when config.lossless is true). Automatic conversion from one format to another is provided but they both incur some loss.
