    {
        // Replace 'path_to_receipt_image.jpg' with the actual path to your receipt image file.
        string imagePath = "path_to_receipt_image.jpg";

        // Create an OCR engine instance from the Receipt-OCR library.

        try
        {
            // Load the receipt image.
            ocr.Image = imagePath;

            // Perform OCR text extraction.
            string extractedText = ocr.Recognize();
            
            // Print the extracted text or use it as needed.
            Console.WriteLine("Extracted Text from Receipt:");
