#### Instalation

`npm install image-size`

#### Usage

```javascript
var sizeOf = require('image-size');
var dimensions = sizeOf('images/funny-cats.png');
console.log(dimensions.width, dimensions.height);
```

##### Async version
```javascript
var sizeOf = require('image-size');
sizeOf('images/funny-cats.png', function (err, dimensions) {
  console.log(dimensions.width, dimensions.height);
});
```

##### Using a url
```javascript
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**

#### Supported formats

not a direct port, but an attempt to have something like
