Code Example

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

// Import the IronOcr namespace to use its OCR functionality
using IronOcr;

// Create a new IronTesseract instance
var Ocr = new IronTesseract();
// Set the OCR language to Lao
Ocr.Language = OcrLanguage.Lao;

// Use a using statement to ensure proper disposal of resources
using (var Input = new OcrInput(@"images\Lao.png"))
{
    // Perform OCR on the input image
    var Result = Ocr.Read(Input);
    // Extract all text from the OCR result
    var AllText = Result.Text;
    
    // Output the recognized text for verification
    Console.WriteLine(AllText);
}

// Import the IronOcr namespace to use its OCR functionality
using IronOcr;

// Create a new IronTesseract instance
var Ocr = new IronTesseract();
// Set the OCR language to Lao
Ocr.Language = OcrLanguage.Lao;

// Use a using statement to ensure proper disposal of resources
using (var Input = new OcrInput(@"images\Lao.png"))
{
    // Perform OCR on the input image
    var Result = Ocr.Read(Input);
    // Extract all text from the OCR result
    var AllText = Result.Text;
    
    // Output the recognized text for verification
    Console.WriteLine(AllText);
}

' Import the IronOcr namespace to use its OCR functionality
Imports IronOcr

' Create a new IronTesseract instance
Dim Ocr As New IronTesseract()
' Set the OCR language to Lao
Ocr.Language = OcrLanguage.Lao

' Use a using block to ensure proper disposal of resources
Using Input As New OcrInput("images\Lao.png")
    ' Perform OCR on the input image
    Dim Result = Ocr.Read(Input)
    ' Extract all text from the OCR result
    Dim AllText = Result.Text

    ' Output the recognized text for verification
    Console.WriteLine(AllText)
End Using

' Import the IronOcr namespace to use its OCR functionality
Imports IronOcr

' Create a new IronTesseract instance
Dim Ocr As New IronTesseract()
' Set the OCR language to Lao
Ocr.Language = OcrLanguage.Lao

' Use a using block to ensure proper disposal of resources
Using Input As New OcrInput("images\Lao.png")
    ' Perform OCR on the input image
    Dim Result = Ocr.Read(Input)
    ' Extract all text from the OCR result
    Dim AllText = Result.Text

    ' Output the recognized text for verification
    Console.WriteLine(AllText)
End Using

Explanation:

This code demonstrates how to configure and use IronOCR to perform OCR specifically for the Lao language.
IronTesseract is the main class used for performing OCR operations.
The language is set to Lao using Ocr.Language.
OcrInput is a class used to load images or PDF documents for OCR processing.
The Ocr.Read method processes the input and returns a result containing the recognized text.
The using statement ensures that resources are released after use.
Finally, the recognized text is printed to the console for output verification.
