以下 C# 代码示例演示了如何使用 IronOCR 从图像或 PDF 文档中读取汤加语文本。

// Include the necessary IronOcr namespace
using IronOcr;

class TongaOcrExample
{
    static void Main()
    {
        // Initialize the IronTesseract OCR engine
        var Ocr = new IronTesseract();
        
        // Set the OCR engine to use the Tonga language pack
        Ocr.Language = OcrLanguage.Tonga;
        
        // Load the input image or PDF into OcrInput
        using (var Input = new OcrInput(@"images\Tonga.png"))
        {
            // Perform OCR to read the text from the image
            var Result = Ocr.Read(Input);
            
            // Retrieve the full text recognition result
            var AllText = Result.Text;

            // Output the result or process further as needed
            System.Console.WriteLine(AllText);
        }
    }
}

// Include the necessary IronOcr namespace
using IronOcr;

class TongaOcrExample
{
    static void Main()
    {
        // Initialize the IronTesseract OCR engine
        var Ocr = new IronTesseract();
        
        // Set the OCR engine to use the Tonga language pack
        Ocr.Language = OcrLanguage.Tonga;
        
        // Load the input image or PDF into OcrInput
        using (var Input = new OcrInput(@"images\Tonga.png"))
        {
            // Perform OCR to read the text from the image
            var Result = Ocr.Read(Input);
            
            // Retrieve the full text recognition result
            var AllText = Result.Text;

            // Output the result or process further as needed
            System.Console.WriteLine(AllText);
        }
    }
}
