example
const fs = require('fs')
const { Screenshots } = require('node-screenshots')
let capturer = Screenshots.fromPoint(100, 100)
console.log(capturer, capturer.id)
// 同步截图
let image = capturer.captureSync()
fs.writeFileSync('./a.png', image)
// 异步获取截图
capturer.capture().then(data => {
console.log(data)
fs.writeFileSync(`${capturer.id}.png`, data)
})
// 获取所有屏幕截图
let all = Screenshots.all()
all.forEach(capturer => {
console.log({
id: capturer.id,
x: capturer.x,
y: capturer.y,
width: capturer.width,
height: capturer.height,
scale: capturer.scale,
rotation: capturer.rotation
})
capturer.captureSync()
})
// 从屏幕id获取截图,id可以通过 `Screenshots.all()` 获取,也可以通过electron的 `screen.getAllDisplays()` 获取
let sc = Screenshots.fromDisplay(71)
