electron 怎麼截圖

本文介紹如何在 Electron 應用程式中擷取螢幕截圖。它涵蓋了截取特定視窗或區域的螢幕截圖，取得除視窗框架之外的整個螢幕的螢幕截圖，以及儲存或共用擷取的ima

如何在Electron中截取螢幕截圖

1.如何在Electron 應用程式中截取特定視窗或區域的螢幕截圖？

在 Electron 中，您可以使用 screenshot 方法截取特定視窗或區域的螢幕截圖。操作方法如下：screenshot method. Here's how you do it:

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.
});

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

const options = {
  x: 0,
  y: 0,
  width: 200,
  height: 100
};

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

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:

const { BrowserWindow } = require('electron');

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

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

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

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');
}
});

要截取特定區域的螢幕截圖，請使用帶有非預設選項的capturePage 函數：

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');
    }
  });
}
});

• 2.如何在Electron App 中取得除視窗框架之外的整個螢幕的螢幕截圖？

  要在Electron 中捕獲除視窗框架之外的整個螢幕的螢幕截圖，請建立一個沒有框架的新視窗並擷取螢幕：
rrreee
• frame: false 選項可確保視窗沒有邊框或標題欄，從而產生僅包含螢幕內容的螢幕截圖。

  3.如何在 Electron 應用程式中儲存或分享螢幕截圖？

獲得螢幕截圖圖像後，您可以將其儲存到檔案或使用特定於平台的方法共用它。以下是範例：🎜🎜🎜🎜🎜將螢幕截圖儲存到檔案：🎜🎜rrreee🎜🎜🎜🎜使用系統對話框分享螢幕截圖：🎜🎜rrreee🎜🎜
