> Create screenshots using [node-webkit](https://github.com/rogerwang/node-webkit)

## Install

```shell
npm install node-webkit-screenshot
```

## Usage

```js
var fs = require('fs');
var screenshot = require('node-webkit-screenshot');

screenshot({
  url : 'http://google.de',
  width : 1024,
  height : 768
})
.then(function(buffer){
  fs.writeFile('./out.png', buffer, function(){
    // This will close the screenshot service
    screenshot.close();
  });
});

```

#### screenshot(options)

##### port

Type: `number`
Default: `3000`

Specify custom port number for the webkit browser

##### delay

Type: `number` *(seconds)*
Default: `0`

Delay capturing the screenshot.

Useful when the site does things after load that you want to capture.

##### format

Type: `string` png|jpeg
Default: `png`

Specify the image type fot he screenshot

##### width

Type: `int`
Default: `0`

Specify the with of the browser window

##### height

Type: `int`
Default: `0`

Specify the height of the browser window

##### crop (since `0.2.1`)
Type: `Object`
Default: `undefined`

This will only work if generating png's.
A crop object may look like this:
```js
{
  top : 10,
  left : 10,
  width : 100,
  height : 100
}
```

#### close()

This will close the `node-webkit` process. You have to call this function before node is able to exit.

## Troubleshooting

If you would like to use this on travis or with a framebuffer like xvfb than you need to set the environment variable
`NODESCREENSHOT_SHOW` to `1`. (`export NODESCREENSHOT_SHOW`).
See this [`.travis.yml`](https://github.com/FWeinb/node-webkit-screenshot/blob/master/.travis.yml) for more information
