好的，以下是使用Jimp图像处理库翻译的代码：

const fs = require('fs');
const Jimp = require('jimp');

async function parse_bg_captcha(img, im_show = false, save_path = null) {
  let _img;
  if (typeof img === 'string') {
    _img = await Jimp.read(img);
  } else if (img instanceof Buffer) {
    _img = await Jimp.read(img);
  } else {
    throw new Error(`输入图片类型错误, 必须是<string>/<Buffer>: ${typeof img}`);
  }

  // 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,
        h_sep = 80;

  // 还原后的背景图
  const new_img = await new Jimp(260, 160, 0xFFFFFF);

  for (let idx = 0; idx < _Ge.length; idx++) {
    const x = _Ge[idx] % 26 * 12 + 1;
    const y = _Ge[idx] > 25 ? h_sep : 0;

    // 从背景图中裁剪出对应位置的小块
    const img_cut = _img.clone().crop(x, y, w_sep, h_sep);

    // 将小块拼接到新图中
    const new_x = idx % 26 * 10;
    const new_y = idx > 25 ? h_sep : 0;
    new_img.blit(img_cut, new_x, new_y);
  }

  if (save_path) {
    await new_img.writeAsync(save_path);
  }

  if (im_show) {
    await new_img.getBufferAsync(Jimp.MIME_JPEG, (err, buffer) => {
      if (err) {
        console.error(err);
        return;
      }
      const base64Img = Buffer.from(buffer).toString('base64');
      console.log(`data:image/jpeg;base64,${base64Img}`);
    });
  }

  return new_img;
}

parse_bg_captcha('bg.webp', true, 'bg.jpg')
  .then(img => console.log('还原完成'))
  .catch(err => console.error(err));

请注意，在Node.js中使用Jimp图像处理库时，需要使用异步函数或Promise来处理图像操作，并且不支持同步操作，因此代码中使用了async/await和Promise来执行图像操作。
