    Parameters

    BarcodeNo

    Return Value

    The barcode confidence. In the range [(less trust) 0 - 100 (full trust)]
    Remarks

    This method is used in the "Barcode Recognition" Demo.

    Example
    Finding Micro Qr Code barcodes in an image and writing complete barcodes info into a file.
    using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
    {
        int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.jpg", false);
     
        // Set to 0, so all the Micro QR Codes in the image should be found.
        int expectedBarcodes = 0;
     
        // Perform scanning at best speed, ignoring very damaged barcodes.
        BarcodeQRReaderScanMode mode = BarcodeQRReaderScanMode.BestSpeed;
     
        // Start the Micro Qr Code scanning process and write info into a text file.
        gdpictureImaging.BarcodeMicroQRReaderDoScan(imageID, mode, expectedBarcodes);
     
        using (System.IO.StreamWriter file = new System.IO.StreamWriter("MicroQrCodes.txt"))
        {
            int barcodesFound = gdpictureImaging.BarcodeMicroQRReaderGetBarcodeCount();
     
            for (int i = 1; i <= barcodesFound; i++)
            {
                // Decoded information.
                file.WriteLine("Decoded info = " + gdpictureImaging.BarcodeMicroQRReaderGetBarcodeValue(i));
     
                // The skew angle of the barcode, in degrees.
                file.WriteLine("Skew angle = " + gdpictureImaging.BarcodeMicroQRReaderGetBarcodeSkewAngle(i));
     
                // Confidence in result, in percentage (values from 0 to 100).
                file.WriteLine("Confidence = " + gdpictureImaging.BarcodeMicroQRReaderGetBarcodeConfidence(i));
     
                // The version of a Micro Qr Code, in range 1-4. The higher the version, the larger the barcode is.
                file.WriteLine("Version = " + gdpictureImaging.BarcodeMicroQRReaderGetVersion(i));
     
                // The barcode position, given by the coordinates of the corners.

            }
        }
     
        // Release used resources.
