This is mainly just one function to call:

Please have a look at the file src/webp/decode.h for the details.

pre-allocated buffer.
To detect a WebP file and gather picture's dimensions, the function:
int WebPGetInfo(const uint8_t* data, uint32_t data_size,
int WebPGetInfo(const uint8_t* data, size_t data_size,
