Package description
The image-size npm package is a module that provides a simple API to determine the dimensions of an image file. It supports a variety of image formats, including but not limited to JPEG, PNG, GIF, BMP, and WebP. The package can be used in both synchronous and asynchronous contexts and can handle local files as well as remote images via URLs.
Synchronous image size retrieval
This feature allows you to synchronously get the dimensions of an image by providing the path to the image file.
const sizeOf = require('image-size');
const dimensions = sizeOf('path/to/image.jpg');
console.log(dimensions.width, dimensions.height);Asynchronous image size retrieval
This feature allows you to asynchronously get the dimensions of an image by providing the path to the image file and a callback function.
const sizeOf = require('image-size');
sizeOf('path/to/image.jpg', (err, dimensions) => {
if (err) throw err;
console.log(dimensions.width, dimensions.height);
});Image size retrieval from a buffer
This feature allows you to get the dimensions of an image from a buffer, which is useful when you have the image data in memory rather than stored in a file.
const sizeOf = require('image-size');
const fs = require('fs');
fs.readFile('path/to/image.jpg', (err, data) => {
if (err) throw err;
const dimensions = sizeOf(data);
console.log(dimensions.width, dimensions.height);
});Sharp is a high-performance Node.js image processing library that provides a wide range of functionality including resizing, cropping, rotating, and format conversion. It is faster than image-size as it's built on libvips, but it's more complex and has a larger footprint.
Jimp is an image processing library for Node.js that allows for image manipulation and conversion in pure JavaScript without any native dependencies. It offers more features than image-size, such as image manipulation, but it is slower due to its JavaScript-based implementation.
Probe-image-size is a Node.js module to determine image sizes and types in a streaming fashion, which can be useful for remote images. It is similar to image-size but focuses on working with streams and can handle partial data, which is useful for getting dimensions without downloading the whole image.
Readme
npm install image-size
var sizeOf = require('image-size');
var dimesions = sizeOf('images/funny-cats.png');
console.log(dimesions.width, dimesions.height);
not a direct port, but an attempt to have something like dabble's imagesize as a node module.
