以下是使用Node.js的ImageMagick库来实现类似的功能的示例代码：

const fs = require('fs');
const gm = require('gm').subClass({ imageMagick: true });

function parseBgCaptcha(imgPath, imShow = false, savePath = null) {
  return new Promise((resolve, reject) => {
    gm(imgPath)
      .size((err, size) => {
        if (err) {
          reject(err);
          return;
        }

        const wSep = 10, hSep = 80;
        const newImg = gm(size.width, size.height, '#fff');

        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
        ];

        ge.forEach((idx) => {
          const x = idx % 26 * 12 + 1;
          const y = idx > 25 ? hSep : 0;
          const imgCut = gm(imgPath).crop(wSep, hSep, x, y);
          const newx = idx % 26 * 10;
          const newy = idx > 25 ? hSep : 0;
          newImg.draw('image Over', newx, newy, wSep, hSep, imgCut);
        });

        if (imShow) {
          newImg.write(`${savePath.split('.')[0]}.png`, (err) => {
            if (err) {
              reject(err);
            } else {
              console.log(`Image saved as ${savePath.split('.')[0]}.png`);
            }
          });
        }

        if (savePath !== null) {
          newImg.write(savePath, (err) => {
            if (err) {
              reject(err);
            } else {
              resolve(newImg);
            }
          });
        } else {
          resolve(newImg);
        }
      });
  });
}

// usage
parseBgCaptcha('bg.webp', true, 'bg.jpg');

这段代码使用ImageMagick库从输入图片中裁剪出对应位置的小块，然后将它们拼接到新图中。如果您想要显示新生成的图像，可以设置imShow参数为true，然后将其保存为PNG格式。如果您想要将新图像保存到磁盘上，请设置savePath参数。
