electron 截图插件
import debug from 'electron-debug'
import { app, globalShortcut } from 'electron'
import Screenshots from './screenshots'
app.whenReady().then(() => {
const screenshots = new Screenshots()
globalShortcut.register('ctrl+shift+a', () => {
screenshots.startCapture()
screenshots.$view.webContents.openDevTools()
})
// 点击确定按钮回调事件
screenshots.on('ok', (e, buffer, bounds) => {
console.log('capture', buffer, bounds)
})
// 点击取消按钮回调事件
screenshots.on('cancel', () => {
console.log('capture', 'cancel1')
})
screenshots.on('cancel', e => {
// 执行了preventDefault
// 点击取消不会关闭截图窗口
e.preventDefault()
console.log('capture', 'cancel2')
})
// 点击保存按钮回调事件
screenshots.on('save', (e, buffer, bounds) => {
console.log('capture', buffer, bounds)
})
debug({ showDevTools: true, devToolsMode: 'undocked' })
})
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') {
app.quit()
}
})
{
externals: {
'electron-screenshots': 'require("electron-screenshots")'
}
}
vue-cli-plugin-electron-builder
配置示例vue-cli-plugin-electron-builder-issue// vue.config.js
module.exports = {
publicPath: '.',
pluginOptions: {
electronBuilder: {
// 不打包,使用 require 加载
externals: ['electron-screenshots']
}
}
}
globalShortcut.register('esc', () => {
if (screenshots.$win?.isFocused()) {
screenshots.endCapture()
}
})
BrowserWindow
,减少创建窗口的开销,可用以下代码实现。需注意,启用该功能,会导致window-all-closed
事件不触发,因此需要手动关闭截图窗口// 是否复用截图窗口,加快截图窗口显示,默认值为 false
// 如果设置为 true 则会在第一次调用截图窗口时创建,后续调用时直接使用
// 且由于窗口不会 close,所以不会触发 app 的 `window-all-closed` 事件
const screenshots = new Screenshots({
singleWindow: true
})
Debugger
类型产考debug
中的Debugger
类型export type LoggerFn = (...args: unknown[]) => void
export type Logger = Debugger | LoggerFn
export interface Lang {
magnifier_position_label?: string
operation_ok_title?: string
operation_cancel_title?: string
operation_save_title?: string
operation_redo_title?: string
operation_undo_title?: string
operation_mosaic_title?: string
operation_text_title?: string
operation_brush_title?: string
operation_arrow_title?: string
operation_ellipse_title?: string
operation_rectangle_title?: string
}
export interface ScreenshotsOpts {
lang?: Lang
// 调用日志,默认值为 debug('electron-screenshots')
// debug https://www.npmjs.com/package/debug
logger?: Logger
// 是否复用截图窗口,加快截图窗口显示,默认值为 false
// 如果设置为 true 则会在第一次调用截图窗口时创建,后续调用时直接使用
// 且由于窗口不会 close,所以不会触发 app 的 `window-all-closed` 事件
singleWindow?: boolean
}

---|---|---|
ok | 截图确认事件 | (event: Event, buffer: Buffer, data: ScreenshotsData) => void |
cancel | 截图取消事件 | (event: Event) => void |
save | 截图保存事件 | (event: Event, buffer: Buffer, data: ScreenshotsData) => void |
event
对象可调用preventDefault
方法来阻止默认事件,例如阻止默认保存事件const screenshots = new Screenshots({
lang: {
magnifier_position_label: 'Position',
operation_ok_title: 'Ok',
operation_cancel_title: 'Cancel',
operation_save_title: 'Save',
operation_redo_title: 'Redo',
operation_undo_title: 'Undo',
operation_mosaic_title: 'Mosaic',
operation_text_title: 'Text',
operation_brush_title: 'Brush',
operation_arrow_title: 'Arrow',
operation_ellipse_title: 'Ellipse',
operation_rectangle_title: 'Rectangle'
}
})
screenshots.on('save', (e, buffer, data) => {
// 阻止插件自带的保存功能
// 用户自己控制保存功能
e.preventDefault()
// 用户可在这里自己定义保存功能
console.log('capture', buffer, data)
})
screenshots.startCapture()
