Code Example

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

using IronOcr;

public class OcrExample
{
    public void ReadCyrillicText()
    {
        // Initialize a new instance of the IronTesseract OCR engine
        var Ocr = new IronTesseract();

        // Set the OCR engine to use the Cyrillic language package
        Ocr.Language = OcrLanguage.Cyrillic;

        // Create a new OCR input from an image file
        using (var Input = new OcrInput(@"images\Cyrillic.png"))
        {
            // Read the image using the OCR engine
            var Result = Ocr.Read(Input);

            // Retrieve Recognized Text
            var AllText = Result.Text;

            // Output the recognized text to the console
            Console.WriteLine(AllText);
        }
    }
}

using IronOcr;

public class OcrExample
{
    public void ReadCyrillicText()
    {
        // Initialize a new instance of the IronTesseract OCR engine
        var Ocr = new IronTesseract();

        // Set the OCR engine to use the Cyrillic language package
        Ocr.Language = OcrLanguage.Cyrillic;

        // Create a new OCR input from an image file
        using (var Input = new OcrInput(@"images\Cyrillic.png"))
        {
            // Read the image using the OCR engine
            var Result = Ocr.Read(Input);

            // Retrieve Recognized Text
            var AllText = Result.Text;

            // Output the recognized text to the console
            Console.WriteLine(AllText);
        }
    }
}

Imports IronOcr

Public Class OcrExample
	Public Sub ReadCyrillicText()
		' Initialize a new instance of the IronTesseract OCR engine
		Dim Ocr = New IronTesseract()

		' Set the OCR engine to use the Cyrillic language package
		Ocr.Language = OcrLanguage.Cyrillic

		' Create a new OCR input from an image file
		Using Input = New OcrInput("images\Cyrillic.png")
			' Read the image using the OCR engine
			Dim Result = Ocr.Read(Input)

			' Retrieve Recognized Text
			Dim AllText = Result.Text

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

Imports IronOcr

Public Class OcrExample
	Public Sub ReadCyrillicText()
		' Initialize a new instance of the IronTesseract OCR engine
		Dim Ocr = New IronTesseract()

		' Set the OCR engine to use the Cyrillic language package
		Ocr.Language = OcrLanguage.Cyrillic

		' Create a new OCR input from an image file
		Using Input = New OcrInput("images\Cyrillic.png")
			' Read the image using the OCR engine
			Dim Result = Ocr.Read(Input)

			' Retrieve Recognized Text
			Dim AllText = Result.Text

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

IronTesseract: This is the OCR engine class you use to configure and execute OCR tasks.
OcrInput: A class representing the input image or document you want to perform OCR on.
OcrLanguage.Cyrillic: Specifies that the OCR engine should use the Cyrillic language package for recognition.
Result.Text: Accesses the recognized text from the OCR result object.

This example demonstrates a simple use case where an image with Cyrillic text is processed to extract the text.
