    BarcodePDF417ReaderGetBarcodeX2 Method (GdPictureImaging)
    In This Topic
    Returns the X position (in pixels) of the top-right corner of a barcode detected by the BarcodePDF417ReaderDoScan method. If ROI has been set, this coordinate is relative to the used ROI.

    Example
    Finding PDF417 barcodes in an image and writing complete barcodes info into a file.

        // Perform scanning at best speed, ignoring very damaged barcodes.
        BarcodePDF417ReaderScanMode mode = BarcodePDF417ReaderScanMode.BestSpeed;
     
        // Start the PDF417 barcode scanning process and write info into a text file.
