OCRソフトウェアデモのコード例を用いてIronOCRでOCRを実行する方法を探ります。

using IronOcr;

class ReceiptScanner
{
    static void Main()
    {
        // Set the license key for IronOCR
        IronOcr.License.LicenseKey = "YOUR-KEY";

        // Instantiate OCR engine
        var ocr = new IronTesseract();

        using var inputPhoto = new OcrInput();
        inputPhoto.LoadImage("supermarketexample.jpg");

        // Perform OCR on the loaded image
        OcrResult result = ocr.Read(inputPhoto);

        // Output the text extracted from the receipt
        string text = result.Text;
        Console.WriteLine(text);
    }
}
