electron 怎么截图

本文介绍了如何在 Electron 应用程序中捕获屏幕截图。它涵盖了截取特定窗口或区域的屏幕截图，获取除窗口框架之外的整个屏幕的屏幕截图，以及保存或共享捕获的ima

如何在Electron中截取屏幕截图

1.如何在 Electron 应用中截取特定窗口或区域的屏幕截图？

在 Electron 中，您可以使用 screenshot 方法截取特定窗口或区域的屏幕截图。操作方法如下：screenshot method. Here's how you do it:

<code class="js">const { BrowserWindow } = require('electron');

const window = new BrowserWindow({ width: 800, height: 600 });

window.capturePage((image) => {
  // Save the image to a file or share it using an appropriate platform-specific method.
});</code>

For taking screenshots of a specific region, use the capturePage function with non-default options:

<code class="js">const options = {
  x: 0,
  y: 0,
  width: 200,
  height: 100
};

window.capturePage(options, (image) => {
  // ...
});</code>

2. How to Get a Screenshot of the Entire Screen Excluding the Window Frame in Electron App?

To capture a screenshot of the entire screen excluding the window frame in Electron, create a new window without a frame and capture the screen:

<code class="js">const { BrowserWindow } = require('electron');

const window = new BrowserWindow({ frame: false, show: false });

window.capturePage((image) => {
  // ...
});</code>

The frame: false option ensures that the window doesn't have a border or title bar, resulting in a screenshot that only includes the screen content.

3. How to Save or Share a Screenshot in Electron App?

Once you have the screenshot image

<code class="js">const fs = require('fs');

fs.writeFile('my-screenshot.png', image.toPNG(), (err) => {
if (err) {
  console.log('Error saving the screenshot:', err);
} else {
  console.log('Screenshot saved successfully');
}
});</code>

要截取特定区域的屏幕截图，请使用带有非默认选项的 capturePage 函数：

<code class="js">const dialog = require('electron').dialog;

dialog.showSaveDialog(window, {
title: 'Save screenshot',
filters: [
  {
    name: 'PNG Images',
    extensions: ['png']
  }
]
}, (file) => {
if (file) {
  fs.writeFile(file, image.toPNG(), (err) => {
    if (err) {
      console.log('Error saving the screenshot:', err);
    } else {
      console.log('Screenshot saved successfully');
    }
  });
}
});</code>

2.如何在 Electron App 中获取除窗口框架之外的整个屏幕的屏幕截图？

要在 Electron 中捕获除窗口框架之外的整个屏幕的屏幕截图，请创建一个没有框架的新窗口并捕获屏幕：

rrreee

frame: false 选项可确保窗口没有边框或标题栏，从而生成仅包含屏幕内容的屏幕截图。

3.如何在 Electron 应用程序中保存或共享屏幕截图？

获得屏幕截图图像后，您可以将其保存到文件或使用特定于平台的方法共享它。以下是示例：🎜🎜🎜🎜🎜将屏幕截图保存到文件：🎜🎜rrreee🎜🎜🎜🎜使用系统对话框共享屏幕截图：🎜🎜rrreee🎜🎜
