API

`int version()`

Returns the version of libwebp as a number. va.b.c is encoded as 0x0a0b0c

`uint8_t* create_buffer(int width, int height)`

Allocates an RGBA buffer for an image with the given dimension.

`void destroy_buffer(uint8_t* p)`

Frees a buffer created with create_buffer.

`void encode(uint8_t* image_buffer, int image_width, int image_height, float quality)`

Encodes the given image with given dimension to WebP. quality is a number between 0 and 100. The higher the number, the better the quality of the encoded image. The result is implicitly stored and can be accessed using the get_result_*() functions.

`void free_result()`

Frees the result created by encode().

`int get_result_pointer()`

Returns the pointer to the start of the buffer holding the encoded data.

`int get_result_size()`

Returns the length of the buffer holding the encoded data.
