-# ImageQuant
-
- Source: <https://github.com/ImageOptim/libimagequant>
- Version: v2.12.1
-
-## Dependencies
-
- 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()`.

 Returns the version of MozJPEG 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, 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.
+
 ### `void free_result()`

 Frees the result created by `encode()`.

-### `Uint8Array encode(std::string image_in, int image_width, int image_height, MozJpegOptions opts)`
+### `int get_result_pointer()`

-Encodes the given image with given dimension to JPEG. Options looks like this:
+Returns the pointer to the start of the buffer holding the encoded data.

-```c++

-# OptiPNG
-
- Source: <https://sourceforge.net/project/optipng>
- Version: v0.7.7
-
-## Dependencies
-
- Docker
-
-## Example
-
-See `example.html`
-
-## API
-
-### `int version()`
-
-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()`.

+Decodes the given webp file into raw RGBA. The result is implicitly stored and can be accessed using the `get_result_*()` functions.

 ### `void free_result()`

 Frees the result created by `decode()`.
+
+### `int get_result_pointer()`
+
+Returns the pointer to the start of the buffer holding the encoded data. Length is width x height x 4 bytes.
+
+### `int get_result_width()`
+
+Returns the width of the image.
+
+### `int get_result_height()`
+
+Returns the height of the image.
