/**
* @class
*
* A `Jimp` class enables you to:class
*
* - Read an image into a "bit map" (a collection of pixels)
* - Modify the bit map through methods that change the pixels
* - Write the bit map back to an image buffer
*
* @example
*
* #### Basic
*
* You can use the Jimp class to make empty images.
* This is useful for when you want to create an image that composed of other images on top of a background.
*
* ```ts
* import { Jimp } from "jimp";
*
* const image = new Jimp({ width: 256, height: 256, color: 0xffffffff });
* const image2 = new Jimp({ width: 100, height: 100, color: 0xff0000ff });
*
* image.composite(image2, 50, 50);
* ```
*
* #### Node
*
* You can use jimp in Node.js.
* For example you can read an image from a file and resize it and
* then write it back to a file.
*
* ```ts
* import { Jimp } from "jimp";
* import { promises as fs } from "fs";
*
* const image = await Jimp.read("test/image.png");
*
* image.resize(256, 100);
* image.greyscale();
*
* await image.write('test/output.png');
* ```
*
* #### Browser
*
* You can use jimp in the browser by reading files from URLs
*
* ```ts
* import { Jimp } from "jimp";
*
* const image = await Jimp.read("https://upload.wikimedia.org/wikipedia/commons/0/01/Bot-Test.jpg");
*
* image.resize(256, 100);
* image.greyscale();
*
* const output = await image.getBuffer("test/image.png");
*
* const canvas = document.createElement("canvas");
*
* canvas.width = image.bitmap.width;
* canvas.height = image.bitmap.height;
*
* const ctx = canvas.getContext("2d");
* ctx.putImageData(image.bitmap, 0, 0);
*
* document.body.appendChild(canvas);
* ```
