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}}");
