Code Example

This C# code example reads Finnish text from an Image or PDF document.

// Ensure you have installed the IronOcr.Languages.Finnish package before using this code.
// You can install it via NuGet package manager.

using IronOcr;

var Ocr = new IronTesseract(); // Create a new instance of the IronTesseract OCR engine
Ocr.Language = OcrLanguage.Finnish; // Set the language of the OCR engine to Finnish

// Using a using statement to ensure the OcrInput gets disposed of correctly
using (var Input = new OcrInput(@"images\Finnish.png")) // Path to the image/PDF containing Finnish text
{
    var Result = Ocr.Read(Input); // Perform OCR on the input file
    var AllText = Result.Text; // Extract the recognized text as a string

    // Output or process the extracted text as required
    Console.WriteLine(AllText); // Example of outputting the text to the console
}
