request-image-size

This NodeJS module is a clone of http-image-size by Johannes J. Schmidt. It detects image dimensions via request instead of http/https, allowing for more flexibility and following redirects by default. Tries image-size on each chunk received until the image dimensions are obtained, and the request is aborted.

Basic usage

var size = require('request-image-size');

size('http://nodejs.org/images/logo.png', function(err, dimensions, length) {
  console.log(err, dimensions, length);
});

Advanced usage

Specifying a request options object (docs):

var size = require('request-image-size');

var options = {
  url: 'http://nodejs.org/images/logo.png',
  headers: {
    'User-Agent': 'request-image-size'
  }
};

size(options, function(err, dimensions, length) {
  console.log(err, dimensions, length);
});

The callback receives three arguments: err, dimensions, length:

dimensions is in the form { height: 1063, width: 1600 }.
length is the number of bytes loaded.
