-Google Analytics is used to record the following:
-
-* [Basic visit data](https://support.google.com/analytics/answer/6004245?ref_topic=2919631).
-* Before and after image size once an image is downloaded. These values are rounded to the nearest

-# 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()`.

-## API
-
-### `int version()`
-
-Returns the version of libwebp as a number. va.b.c is encoded as 0x0a0b0c
-
-### `RawImage decode(std::string buffer)`
-
-Decodes the given webp buffer into raw RGBA. `RawImage` is a class with 3 fields: `buffer`, `width`, and `height`.
-
-### `void free_result()`
-
-Frees the result created by `decode()`.
