IronOCR admite 125 idiomas internacionales, pero solo inglés está instalado en IronOCR como estándar.

Los paquetes de idiomas adicionales se pueden agregar fácilmente a tu proyecto de C#, VB o ASP .NET a través de NuGet o como DLLs que pueden descargarse y añadirse como referencias del proyecto.

Ejemplos de código

Ejemplo de idioma internacional

Install-Package IronOcr.Languages.ChineseSimplified
using IronOcr;

var ocr = new IronTesseract();
// Set the OCR to use Chinese Simplified
ocr.Language = OcrLanguage.ChineseSimplified;

using (var input = new OcrInput())
{
    // Add an image to be processed
    input.AddImage("img/chinese.gif");

    // Optional: Enhance the input by deskewing or denoising the image
    // input.Deskew();
    // input.DeNoise();

    // Process the image and retrieve the result
    var result = ocr.Read(input);

    // Store the recognized text in a string
    string testResult = result.Text;

    // Save the recognized text to a file since the console might not display Unicode characters properly
    result.SaveAsTextFile("chinese.txt");
}
using IronOcr;

var ocr = new IronTesseract();
// Set the OCR to use Chinese Simplified
ocr.Language = OcrLanguage.ChineseSimplified;

using (var input = new OcrInput())
{
    // Add an image to be processed
