Installation

The first thing we have to do is install the Khmer OCR package to your .NET project.

PM > Install-Package IronOcr.Languages.Khmer

Code Example

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

// Make sure the IronOCR package is installed:
// PM> Install-Package IronOcr.Languages.Khmer
using IronOcr;

class KhmerOcrExample
{
    static void Main(string[] args)
    {
        // Create a new instance of IronTesseract for OCR processes
        var Ocr = new IronTesseract();
        
        // Specify the language for OCR as Khmer
        Ocr.Language = OcrLanguage.Khmer;
        
        // Define the path of the image file containing Khmer text
        using (var Input = new OcrInput(@"images\Khmer.png"))
        {
            // Perform OCR on the input image
            var Result = Ocr.Read(Input);
            
            // Retrieve the recognized text
            var AllText = Result.Text;
            
            // Output the recognized text to the console
            Console.WriteLine(AllText);
        }
    }
}

This example demonstrates how to read Khmer text from an image file using IronOCR in a .NET C# application.
