What are @jimp/plugin-rotate's main functionalities?

Rotate Image

This feature allows you to rotate an image by a specified number of degrees. In this example, the image is rotated by 90 degrees and then saved to a new file.

const Jimp = require('jimp');

Jimp.read('path/to/image.jpg')
  .then(image => {
    return image.rotate(90) // rotate image by 90 degrees
      .write('path/to/rotated-image.jpg'); // save
  })
  .catch(err => {
    console.error(err);
  });

Rotate Image with Background Color

This feature allows you to rotate an image by a specified number of degrees and fill the background with a specified color. In this example, the image is rotated by 45 degrees with a white background.

const Jimp = require('jimp');

Jimp.read('path/to/image.jpg')
  .then(image => {
    return image.rotate(45, false, 0xFFFFFFFF) // rotate image by 45 degrees with white background
      .write('path/to/rotated-image.jpg'); // save
  })
  .catch(err => {
    console.error(err);
  });

@jimp/plugin-rotate

Rotate an image.

Rotates the image counter-clockwise by a number of degrees. By default the width and height of the image will be resized appropriately.

Usage

• @param {number} deg the number of degrees to rotate the image by, counter-clockwise
• @param {string|boolean} mode (optional) resize mode or a boolean, if false then the width and height of the image will not be changed
• @param {function(Error, Jimp)} cb (optional) a callback for when complete

import jimp from "jimp";

async function main() {
  const image = await jimp.read("test/image.png");

  image.rotate(90);
}

main();
