API

Screenshot(url[, opts])

Create a screenshot object for url.

Use opts if passing arguments this way is more convenient than using the api, e.g.:

var s = Screenshot('http://google.com', { width: 800 })
// is the same as
var s = Screenshot('http://google.com').width(800);

Screenshot#width(width)

Set the screenshot's width in pixel. Defaults to 1024.

Screenshot#height(height)

Set the screenshot's height in pixel. Defaults to 768.

Screenshot#format(format)

Set the output format. Supported formats:

  • jpg, jpeg
  • png
  • gif

Defaults to png.

Screenshot#timeout(timeout)

After loading the page, make phantomjs wait for timeout milliseconds before taking the screenshot. Defaults to 0 ms.

Screenshot#capture([fn])

Capture the screenshot and call fn with the possible error and a Buffer containing the image.

If no fn is provided, a thunk/continuable is returned.

If the page has a transparent background, it will be set to white before capturing.

Installation

Make sure you have a working installation of phantomjs in your $PATH.
