Programmatic Usage¶ ↑
npm install image-size --save
Synchronous¶ ↑
var sizeOf = require('image-size'); var dimensions = sizeOf('images/funny-cats.png'); console.log(dimensions.width, dimensions.height);
Asynchronous¶ ↑
var sizeOf = require('image-size'); sizeOf('images/funny-cats.png', function (err, dimensions) { console.log(dimensions.width, dimensions.height); });
NOTE: The asynchronous version doesn't work if the input is a Buffer. Use synchronous version instead.
Using a URL¶ ↑
var url = require('url'); var http = require('http'); var sizeOf = require('image-size'); var imgUrl = 'http://my-amazing-website.com/image.jpeg'; var options = url.parse(imgUrl); http.get(options, function (response) { var chunks = []; response.on('data', function (chunk) { chunks.push(chunk); }).on('end', function() { var buffer = Buffer.concat(chunks); console.log(sizeOf(buffer)); }); });
You can optionally check the buffer lengths & stop downloading the image after a few kilobytes. You don't need to download the entire image
Command-Line Usage (CLI)¶ ↑
npm install image-size --global image-size image1 [image2] [image3] ...
Credits¶ ↑
not a direct port, but an attempt to have something like dabble’s imagesize as a node module.
