using IronOcr;

var Ocr = new IronTesseract(); // Initialize the OCR engine
Ocr.Language = OcrLanguage.EnglishBest; // Set the language to English
Ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5; // Use the preferred Tesseract version

using (var Input = new OcrInput()) // Create an input object for OCR
{
    Input.AddImage(@"Demo.png"); // Add the image file for processing
    var Result = Ocr.Read(Input); // Perform OCR to read text from the image
    Console.WriteLine(Result.Text); // Output the extracted text to the console
    Console.ReadKey(); // Wait for a key press to keep console open
}

using IronOcr;

var Ocr = new IronTesseract(); // Initialize the OCR engine
Ocr.Language = OcrLanguage.EnglishBest; // Set the language to English
Ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5; // Use the preferred Tesseract version

using (var Input = new OcrInput()) // Create an input object for OCR
{
    Input.AddImage(@"Demo.png"); // Add the image file for processing
    var Result = Ocr.Read(Input); // Perform OCR to read text from the image
    Console.WriteLine(Result.Text); // Output the extracted text to the console
