How to Read License Plates using IronOCR

using IronOcr;
using System;

// Initialize the IronTesseract OCR object
var ocr = new IronTesseract();

// Whitelist characters that are typically found in license plates
ocr.Configuration.WhiteListCharacters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789_";

// Use a using statement to ensure the OcrInput object is disposed of correctly
using (var inputLicensePlate = new OcrInput())
{
    // Load the license plate image
    inputLicensePlate.AddImage("plate.jpeg");

    // Perform OCR to read the license plate. This uses the Read method from the IronTesseract library.
    OcrResult result = ocr.Read(inputLicensePlate);

    // Prepare the output string containing the OCR result and the confidence level
    string output = $"{result.Text}\nResult Confidence: {result.Confidence*100}%";

    // Print the result to the console
    Console.WriteLine(output);
}
