好的,下面是使用 Node.js 重写的代码:
```javascript
const fs = require('fs');
const Jimp = require('jimp');
async function parseBgCaptcha(imgPath, imShow = false, savePath = null) {
// 读取图片
const img = await Jimp.read(imgPath);
// 图片还原顺序, 定值
const Ge = [39, 38, 48, 49, 41, 40, 46, 47, 35, 34, 50, 51, 33, 32, 28, 29, 27, 26, 36, 37, 31, 30, 44, 45, 43, 42, 12, 13, 23, 22, 14, 15, 21, 20, 8, 9, 25, 24, 6, 7, 3, 2, 0, 1, 11, 10, 4, 5, 19, 18, 16, 17];
const w_sep = 10;
const h_sep = 80;
// 还原后的背景图
const newImg = new Jimp(260, 160);
for (let i = 0; i < Ge.length; i++) {
const idx = Ge[i];
const x = idx % 26 * 12 + 1;
const y = idx > 25 ? h_sep : 0;
// 从原图中裁剪出对应位置的小块
const imgCut = img.clone().crop(x, y, w_sep, h_sep);
// 将小块拼接到新图中
const newX = idx % 26 * 10;
const newY = idx > 25 ? h_sep : 0;
newImg.blit(imgCut, newX, newY);
}
if (imShow) {
newImg.write('output.jpg');
}
if (savePath !== null) {
await newImg.writeAsync(savePath);
}
return newImg;
}
if (require.main === module) {
console.log('开始');
parseBgCaptcha('./bg.png', true, 'bg.jpg');
}
```
需要注意的是,这里使用的是 `jimp` 模块,而不是 PIL 或 Pillow 库,因此在实现细节上可能会略有不同。另外,由于 Node.js 是基于事件循环的异步编程模型,在实现上也需要使用异步函数和 Promise 等方式来处理 IO 操作。
