+- Docker
+
+## Example
+
+See `example.html`
+
+## API
+
+### `int version()`
+
+Returns the version of libimagequant as a number. va.b.c is encoded as 0x0a0b0c
+
+### `RawImage quantize(std::string buffer, int image_width, int image_height, int numColors, float dithering)`
+
+Quantizes the given images, using at most `numColors`, a value between 2 and 256. `dithering` is a value between 0 and 1 controlling the amount of dithering. `RawImage` is a class with 3 fields: `buffer`, `width`, and `height`.
+
+### `RawImage zx_quantize(std::string buffer, int image_width, int image_height, float dithering)`
+
+???
+
+### `void free_result()`
+
+Frees the result created by `quantize()`.

-### `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, int quality)`
-
-Encodes the given image with given dimension to JPEG. `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.
-

 Frees the result created by `encode()`.

+Returns the version of optipng as a number. va.b.c is encoded as 0x0a0b0c
+
+### `ArrayBuffer compress(std::string buffer, {level})`;
+
+`compress` will re-compress the given PNG image via `buffer`. `level` is a number between 0 and 7.
+
+### `void free_result()`
+
+Frees the result created by `compress()`.
