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

        int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.jpg", false);

        int expectedBarcodes = 0;
     
        // Perform scanning at best speed, ignoring very damaged barcodes.
        BarcodeAztecReaderScanMode mode = BarcodeAztecReaderScanMode.BestSpeed;
     
        // Start the Aztec barcode scanning process and write info into a text file.
        gdpictureImaging.BarcodeAztecReaderDoScan(imageID, mode, expectedBarcodes);
     
        using (System.IO.StreamWriter file = new System.IO.StreamWriter("Aztec.txt"))
        {
            int barcodesFound = gdpictureImaging.BarcodeAztecReaderGetBarcodeCount();
