@jimp/plugin-resize

Resize an image.

Resizes the image to a set width and height using a 2-pass bilinear algorithm/

Usage

• @param {number} w the width to resize the image to (or Jimp.AUTO)
• @param {number} h the height to resize the image to (or Jimp.AUTO)
• @param {string} mode (optional) a scaling method (e.g. Jimp.RESIZE_BEZIER)
• @param {function(Error, Jimp)} cb (optional) a callback for when complete

import jimp from 'jimp';

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

	// Resize the image to width 150 and auto height.
	await image.resize(150, jimp.AUTO);

	// Save and overwrite the image
	await image.writeAsync('test/image.png');
}

main();

Auto

Jimp.AUTO can be passes to either the height or width and jimp will scale the image accordingly. Jimp.AUTO cannot be both height and width.

// resize the height to 250 and scale the width accordingly
image.resize(Jimp.AUTO, 250);
// resize the width to 250 and scale the height accordingly
image.resize(250, Jimp.AUTO);

Resize modes

The default resizing algorithm uses a bilinear method.

Optionally, the following constants can be passed to choose a particular resizing algorithm:

Jimp.RESIZE_NEAREST_NEIGHBOR;
Jimp.RESIZE_BILINEAR;
Jimp.RESIZE_BICUBIC;
Jimp.RESIZE_HERMITE;
Jimp.RESIZE_BEZIER;

image.resize(250, 250, Jimp.RESIZE_BEZIER);

sharp

Sharp is a high-performance image processing library that supports resizing, cropping, and various other transformations. It is known for its speed and efficiency, especially with large images. Compared to @jimp/plugin-resize, Sharp offers more advanced features and better performance.

gm

GraphicsMagick (gm) is a powerful image processing library that provides a wide range of image manipulation capabilities, including resizing. It is a wrapper around the GraphicsMagick and ImageMagick tools. While it offers extensive functionality, it requires the installation of external dependencies, unlike @jimp/plugin-resize which is a pure JavaScript solution.

lwip

Lightweight Image Processor (lwip) is a simple and efficient image processing library that supports resizing, cropping, and other basic transformations. It is lightweight and easy to use, but it may not offer as many features or the same level of performance as @jimp/plugin-resize or Sharp.
