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.

            file.WriteLine("Position =  Top-Left=["

                + gdpictureImaging.BarcodeMicroQRReaderGetBarcodeX1(i) + ", " + gdpictureImaging.BarcodeMicroQRReaderGetBarcodeY1(i)

                + "] Top-Right=[" + gdpictureImaging.BarcodeMicroQRReaderGetBarcodeX2(i) + ", " + gdpictureImaging.BarcodeMicroQRReaderGetBarcodeY2(i)

        }

    }

 

    // Release used resources.

    gdpictureImaging.BarcodeMicroQRReaderClear();

    gdpictureImaging.ReleaseGdPictureImage(imageID);
