Package Exports

request-image-size

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (request-image-size) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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.
