What is @jimp/plugin-resize?
@jimp/plugin-resize is a plugin for the Jimp image processing library that provides functionality for resizing images. It allows you to scale images up or down, fit them within specific dimensions, and apply various resizing algorithms.
What are @jimp/plugin-resize's main functionalities?
Resize to specific dimensions
This feature allows you to resize an image to specific dimensions. In this example, the image is resized to 256x256 pixels.
const Jimp = require('jimp');
Jimp.read('path/to/image.jpg')
.then(image => {
return image.resize(256, 256) // resize to 256x256
.write('path/to/resized_image.jpg'); // save
})
.catch(err => {
console.error(err);
});
Scale image proportionally
This feature allows you to scale an image proportionally. In this example, the image is scaled to 50% of its original size.
const Jimp = require('jimp');
Jimp.read('path/to/image.jpg')
.then(image => {
return image.scale(0.5) // scale image to 50%
.write('path/to/scaled_image.jpg'); // save
})
.catch(err => {
console.error(err);
});
Contain image within specific dimensions
This feature allows you to resize an image to fit within specific dimensions while maintaining the aspect ratio. In this example, the image is resized to fit within a 300x300 pixel box.
const Jimp = require('jimp');
Jimp.read('path/to/image.jpg')
.then(image => {
return image.contain(300, 300) // contain within 300x300
.write('path/to/contained_image.jpg'); // save
})
.catch(err => {
console.error(err);
});
Other packages similar to @jimp/plugin-resize
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.
