screenshot(options)
Will return a Promise containing an object like:
{

size: {
width: X
height: N
}
}
In addition to all options that can be passed to the BrowserWindow you can pass:
delay
Type: number
(milliseconds)
Default: 0
Delay capturing the screenshot.
Useful when the site does things after loading that you want to capture.
width
Type: number
Default: 0
Specify the with of the browser window
height
Type: number
Default: 0
Specify the height of the browser window
crop
Type: Object

An crop object may look like this:
{
x : 10,
y : 10,
width : 100,
height : 100
}
css
Type: String
Default: undefined
This css will be injected into the page before the screenshot is taken.
js
Type: String
Default: undefined
It must contain a function definition that takes on parameter e.g.
js: 'function(takeScreenshot){ /*Do some stuff*/ takeScreenshot();}'
or
js: 'takeScreenshot => { /*Do some stuff*/ takeScreenshot();}'
transparent
Type: Boolean
Default: false
This will enable transparency. Keep in mind that most site do set a background color on the html/body tag.
You can overwrite this by using the css
option using something like html,body{ background-color: transparent !important;}
.
page
Type: Boolean
Default: false
This will try to capture the whole page. width
and height
are considered the minimum size.
screenshot.close()
Will close the screenshot service. Needed to let the node process exit

Scale the number of electron processes to scale
processes. This will round-robin the screenshot
jobs across scale
instances.
