困惑啊！！用zxing讀取圖片當中的條形碼

請教個問題：一張圖片當中在不固定位置包含有條形碼，怎麼讀取條形碼出來呢？怎麼讀取一張圖片中的多個條形碼？用zxing讀取圖片當中的條形碼，報錯com.google.zxing.NotFoundException。有大神知道的嗎？謝謝

設置一下TryHarder和PossibleFormats看一下

public static List<string> ScanForBarcodes(string path)
{
  return ScanForBarcodes(new Bitmap(path));
}

public static List<string> ScanForBarcodes(Bitmap bitmap)
{
  // initialize a new Barcode reader.
  BarcodeReader reader = new BarcodeReader
  {
    TryHarder = true, // TryHarder is slower but recognizes more Barcodes
    PossibleFormats = new List<BarcodeFormat> // in the ZXing There is an Enum where all supported barcodeFormats were contained
    {
      BarcodeFormat.CODE_128, 
      BarcodeFormat.QR_CODE,
      //BarcodeFormat. ... ;
    }
  };
  return reader.DecodeMultiple(bitmap).Select(result => result.Text).ToList(); // return only the barcode string.
                                                                               // If you want the full Result use: return reader.DecodeMultiple(bitmap);
}
