// Import the IronOcr namespace
using IronOcr;

// Create a new instance of IronTesseract, which is the OCR engine
var Ocr = new IronTesseract();

// Specify the language to French for OCR processing
Ocr.Language = OcrLanguage.French;

// Load the input image or PDF document
using (var Input = new OcrInput(@"images\French.png"))
{
    // Perform OCR and retrieve the result
    var Result = Ocr.Read(Input);
    
    // Access the text from the OCR result
    var AllText = Result.Text;
    
    // Output or further process `AllText` as needed
}

// Import the IronOcr namespace
using IronOcr;

// Create a new instance of IronTesseract, which is the OCR engine
var Ocr = new IronTesseract();

// Specify the language to French for OCR processing
Ocr.Language = OcrLanguage.French;

// Load the input image or PDF document
using (var Input = new OcrInput(@"images\French.png"))
{
    // Perform OCR and retrieve the result
    var Result = Ocr.Read(Input);
    
    // Access the text from the OCR result
    var AllText = Result.Text;
    
    // Output or further process `AllText` as needed
}
