Hangul Alphabet Language Pack [Korean Alphabet]
Installation
The first step is to install the Hangul Alphabet OCR package to your .NET project.
Code Example
This C# code example reads Hangul Alphabet text from an Image or PDF document.
// Ensure the IronOCR library is installed
// PM> Install-Package IronOcr.Languages.Hangul
using IronOcr;
class Program
{
static void Main()
{
// Create a new instance of IronTesseract for performing OCR
var Ocr = new IronTesseract();
// Specify the Hangul language pack for better accuracy with Korean texts
Ocr.Language = OcrLanguage.Hangul;
// Load the image or PDF you want to read
using (var Input = new OcrInput(@"images\Hangul.png"))
{
// Perform OCR to read the text from the image
var Result = Ocr.Read(Input);
// Extract the recognized text
var AllText = Result.Text;
// Output the text to the console
Console.WriteLine(AllText);
}
}
}' Ensure the IronOCR library is installed
' PM> Install-Package IronOcr.Languages.Hangul
Imports IronOcr
Module Program
Sub Main()
' Create a new instance of IronTesseract for performing OCR
Dim Ocr As New IronTesseract()
' Specify the Hangul language pack for better accuracy with Korean texts
Ocr.Language = OcrLanguage.Hangul
' Load the image or PDF you want to read
Using Input As New OcrInput("images\Hangul.png")
' Perform OCR to read the text from the image
Dim Result = Ocr.Read(Input)
' Extract the recognized text
Dim AllText = Result.Text
' Output the text to the console
Console.WriteLine(AllText)
End Using
End Sub
End ModuleExplanation:
- IronTesseract: This is the main class used to perform OCR operations.
- OcrLanguage.Hangul: This specifies that the OCR engine should use the Hangul language pack, which optimizes the engine for Korean text recognition.
- OcrInput: This is a container for the images or PDFs to be processed.
Ocr.Read(): This method performs the OCR operation and returns a result object containing the recognized text.
