In This Topic
    BarcodeQRReaderGetBarcodeX2 Method (GdPictureImaging)
    In This Topic
    Returns the X position (in pixels) of the top-right corner of a barcode detected by the BarcodeQRReaderDoScan method. If ROI has been set, this coordinate is relative to the used ROI.

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

    Example
    Finding QrCodes in an image and writeing complete barcodes info into a file.
    using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
    {
        int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.jpg", false);
     
        // Set to 0, so all the 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 QrCode scanning process and write complete info into a text file.
        gdpictureImaging.BarcodeQRReaderDoScan(imageID, mode, expectedBarcodes);
     
        using (System.IO.StreamWriter file = new System.IO.StreamWriter("QrCodes.txt"))
        {
            int barcodesFound = gdpictureImaging.BarcodeQRReaderGetBarcodeCount();
     
            for (int i = 1; i <= barcodesFound; i++)
