What is jimp?

Jimp is an image processing library for Node.js that allows for image manipulation and conversion in a variety of ways. It is written entirely in JavaScript and does not require any native dependencies, making it easy to install and use across different platforms.

What are jimp's main functionalities?

Image Manipulation

This code sample demonstrates how to read an image, resize it, change its quality, convert it to greyscale, and then save the edited image.

const Jimp = require('jimp');

// Read the image, resize it and change its quality
Jimp.read('path/to/image.jpg')
  .then(image => {
    return image
      .resize(256, 256) // resize
      .quality(60) // set JPEG quality
      .greyscale() // set greyscale
      .write('path/to/edited-image.jpg'); // save
  })
  .catch(err => {
    console.error(err);
  });

Color Manipulation

This code sample shows how to read an image and adjust its brightness before saving it.

const Jimp = require('jimp');

// Read the image and adjust brightness
Jimp.read('path/to/image.jpg')
  .then(image => {
    return image
      .brightness(0.5) // increase brightness by 50%
      .write('path/to/brighter-image.jpg'); // save
  })
  .catch(err => {
    console.error(err);
  });

Image Conversion

This code sample illustrates how to read an image in one format (JPG) and convert it to another format (PNG) before saving.

const Jimp = require('jimp');

// Read the image and convert it to PNG
Jimp.read('path/to/image.jpg')
  .then(image => {
    return image
      .write('path/to/image.png'); // convert and save as PNG
  })
  .catch(err => {
    console.error(err);
  });
