Methods

• public static void InitLicense(string license)
• public static BarcodeQRCodeReader Create()
• public Result[]? DecodeFile(string filename)
• public Result[]? DecodeBuffer(IntPtr pBufferBytes, int width, int height, int stride, ImagePixelFormat format)
• public Result[]? DecodeBase64(string base64string)
• public static string? GetVersionInfo()
• public void SetParameters(string parameters)

Usage

• Set the license key:

  BarcodeQRCodeReader.InitLicense("DLS2eyJoYW5kc2hha2VDb2RlIjoiMjAwMDAxLTE2NDk4Mjk3OTI2MzUiLCJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSIsInNlc3Npb25QYXNzd29yZCI6IndTcGR6Vm05WDJrcEQ5YUoifQ=="); 
  

• Initialize the barcode and QR code reader object:

  BarcodeQRCodeReader? reader = BarcodeQRCodeReader.Create();
  

• Decode barcode and QR code from an image file:

  Result[]? results = reader.DecodeFile(filename);
  

• Decode barcode and QR code from a base64 string:

  Result[]? results = reader.DecodeBase64(base64string);
  

• Decode barcode and QR code from a buffer:

  BitmapData bmpData = bitmap.LockBits(new Rectangle(0, 0, bitmap.Width, bitmap.Height),
  ImageLockMode.ReadWrite, bitmap.PixelFormat);
  
  BarcodeQRCodeReader.ImagePixelFormat format = BarcodeQRCodeReader.ImagePixelFormat.IPF_ARGB_8888;
  
  switch (bitmap.PixelFormat)
  {
      case PixelFormat.Format24bppRgb:
          format = BarcodeQRCodeReader.ImagePixelFormat.IPF_RGB_888;
          break;
      case PixelFormat.Format32bppArgb:
          format = BarcodeQRCodeReader.ImagePixelFormat.IPF_ARGB_8888;
          break;
      case PixelFormat.Format16bppRgb565:
          format = BarcodeQRCodeReader.ImagePixelFormat.IPF_RGB_565;
          break;
      case PixelFormat.Format16bppRgb555:
          format = BarcodeQRCodeReader.ImagePixelFormat.IPF_RGB_555;
          break;
      case PixelFormat.Format8bppIndexed:
          format = BarcodeQRCodeReader.ImagePixelFormat.IPF_GRAYSCALED;
          break;
  }
  
  Result[]? results = reader.DecodeBuffer(bmpData.Scan0, bitmap.Width, bitmap.Height, bmpData.Stride, format);
  bitmap.UnlockBits(bmpData);
  

• Get SDK version number:

  string? version = BarcodeQRCodeReader.GetVersionInfo();
  

• Customize parameters:

  // Refer to https://www.dynamsoft.com/barcode-reader/parameters/structure-and-interfaces-of-parameters.html?ver=latest
  reader.SetParameters("{\"Version\":\"3.0\", \"ImageParameter\":{\"Name\":\"IP1\", \"BarcodeFormatIds\":[\"BF_QR_CODE\", \"BF_ONED\"], \"ExpectedBarcodesCount\":20}}");
