Code Example

This C# code example reads Czech text from an image or PDF document.

// Import the IronOcr namespace
using IronOcr;

class Program
{
    static void Main()
    {
        // Create a new IronTesseract instance
        var Ocr = new IronTesseract();
        
        // Set the OCR language to Czech
        Ocr.Language = OcrLanguage.Czech;
        
        // Define the input image or PDF and perform OCR
        using (var Input = new OcrInput(@"images\Czech.png"))
        {
            // Read the input and perform OCR
            var Result = Ocr.Read(Input);
            
            // Extract all recognized text
            var AllText = Result.Text;
            
            // Output the recognized text to the console
            Console.WriteLine(AllText);
        }
    }
}

// Import the IronOcr namespace
using IronOcr;

class Program
{
    static void Main()
    {
        // Create a new IronTesseract instance
        var Ocr = new IronTesseract();
        
        // Set the OCR language to Czech
        Ocr.Language = OcrLanguage.Czech;
        
        // Define the input image or PDF and perform OCR
        using (var Input = new OcrInput(@"images\Czech.png"))
        {
            // Read the input and perform OCR
            var Result = Ocr.Read(Input);
            
            // Extract all recognized text
            var AllText = Result.Text;
            
            // Output the recognized text to the console
            Console.WriteLine(AllText);
        }
    }
}

' Import the IronOcr namespace
Imports IronOcr

Module Program
    Sub Main()
        ' Create a new IronTesseract instance
        Dim Ocr = New IronTesseract()

        ' Set the OCR language to Czech
        Ocr.Language = OcrLanguage.Czech

        ' Define the input image or PDF and perform OCR
        Using Input = New OcrInput("images\Czech.png")
            ' Read the input and perform OCR
            Dim Result = Ocr.Read(Input)

            ' Extract all recognized text
            Dim AllText = Result.Text

            ' Output the recognized text to the console
            Console.WriteLine(AllText)
        End Using
    End Sub
End Module

' Import the IronOcr namespace
Imports IronOcr

Module Program
    Sub Main()
        ' Create a new IronTesseract instance
        Dim Ocr = New IronTesseract()

        ' Set the OCR language to Czech
        Ocr.Language = OcrLanguage.Czech

        ' Define the input image or PDF and perform OCR
        Using Input = New OcrInput("images\Czech.png")
            ' Read the input and perform OCR
            Dim Result = Ocr.Read(Input)

            ' Extract all recognized text
            Dim AllText = Result.Text

            ' Output the recognized text to the console
            Console.WriteLine(AllText)
        End Using
    End Sub
End Module

The above code demonstrates how to configure and utilize the IronTesseract class to perform OCR on a given image or PDF.
Ensure the IronOCR.Languages.Czech package is installed in your environment for the code to execute correctly.
The OcrInput class is used to load the image from the specified path, and Ocr.Read() performs the OCR operation.
Result.Text will contain the OCR output which in this case is printed to the console.
