Programmatic Usage

``
npm install buffer-image-size --save
`

$3

`javascript
var sizeOf = require('buffer-image-size');
var dimensions = sizeOf(yourImageBuffer);
console.log(dimensions.width, dimensions.height);
`

$3

No need for asynchronous usage in this fork.

$3

If the target file is an icon (.ico) or a cursor (.cur), the width and height will be the ones of the first found image.

An additional images array is available and returns the dimensions of all the available images

`javascript
var sizeOf = require('buffer-image-size');
var images = sizeOf(icoBuffer).images;
for (const dimensions of images) {
console.log(dimensions.width, dimensions.height);
}
`

$3

`javascript
var url = require('url');
var http = require('http');

var sizeOf = require('buffer-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

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