HarmonyOS 鸿蒙Next Cannot read property createPixelMap of undefined

imageSource.createPixelMap 到这一步报错

具体代码如下：

/**
 * 对图片进行压缩处理
 */
async compressPicture(path: string): Promise<ArrayBuffer> {
  let options = new Options();
  options.maxSize = 1;
  options.quality = 80;
  options.reduceScale = 1;
  // 从path中读取数据
  let stat = fileIo.lstatSync(path)
  let file = fileIo.openSync(path, fileIo.OpenMode.READ_ONLY)
  let buf = new ArrayBuffer(stat.size)
  fileIo.readSync(file.fd, buf)
  let buffArr = new Uint8Array(buf)
  // 进行压缩
  const imageSource: image.ImageSource = image.createImageSource(buffArr);
  let decodingOptions: image.DecodingOptions = {
    editable: true,
    desiredPixelFormat: 3,
  }
  const pixelMap: image.PixelMap = await imageSource.createPixelMap(decodingOptions);
  return this.compressedImage(pixelMap, options);
}
