image-size

get dimensions of any image file

npm install image-size

var sizeOf = require('image-size');
var dimensions = sizeOf('images/funny-cats.png');
console.log(dimensions.width, dimensions.height);
var sizeOf = require('image-size');
sizeOf('images/funny-cats.png', function (errdimensions) {
  console.log(dimensions.width, dimensions.height);
});
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

  • BMP
  • GIF
  • JPEG
  • PNG
  • PSD
  • TIFF
  • WebP
  • SVG
  • SWF

not a direct port, but an attempt to have something like dabble's imagesize as a node module.
