High OCR accuracy
Supports over 125 languages
Easy to integrate with existing projects
Comprehensive documentation and support

How to Use

To use IronOCR in your C# project, first install the IronOCR NuGet package:

Install-Package IronOcr

After installing the package, you can use the following sample code to perform OCR on an image or scanned document:

using IronOcr; 
var ocr = new IronTesseract();
using (var input = new OcrInput()) { 
  input.AddImage("attachment.png"); 
  input.AddPdf("report.pdf"); 
  OcrResult result = ocr.Read(input); 
  string text = result.Text; 
}

using IronOcr; 
var ocr = new IronTesseract();
using (var input = new OcrInput()) { 
  input.AddImage("attachment.png"); 
  input.AddPdf("report.pdf"); 
  OcrResult result = ocr.Read(input); 
  string text = result.Text; 
}

Imports IronOcr
Private ocr = New IronTesseract()
Using input = New OcrInput()
  input.AddImage("attachment.png")
  input.AddPdf("report.pdf")
  Dim result As OcrResult = ocr.Read(input)
  Dim text As String = result.Text
End Using

VB C#

The first line of the code imports the IronOcr namespace, which contains classes and methods required for OCR.

Next, a new instance of the IronTesseract class is created and stored in the variable ocr. IronTesseract is a class that provides advanced OCR functionality, including support for multithreading and automatic image correction.

The using statement is then used to create a new instance of the OcrInput class, which is used to define the input for the OCR process. Inside the using block, two files are added to the input object using the AddImage and AddPdf methods. These files are "attachment.png" and "report.pdf", respectively.

After adding the files, the Read method is called on the IronTesseract object and passed the OcrInput object as an argument. This method performs the OCR process on the input files and returns an OcrResult object, which contains the OCR output.

At last, the OCR output is extracted from the OcrResult object and stored in the "text" variable, which is a string containing the text extracted from the input files. You can further customize the OCR process and manipulate the results using the extensive features provided by the IronOCR library.

Conclusion

Selecting the best OCR software for Windows 10 depends on your specific requirements, budget, and technical expertise. ABBYY FineReader, Adobe Acrobat Pro DC and Readiris are all excellent choices for big companies looking for standalone OCR applications. However, if you need a powerful OCR library for seamless integration with your C# and .NET projects, IronOCR is a perfect choice.
