IronOCR

Contrary to the default Tesseract library, IronOCR extends Tesseract and offers a native C# OCR library with increased accuracy, performance, and stability. Text from PDFs and photos can be extracted using .NET software and websites. It may output plain text or structured data and supports many foreign languages. It can read barcodes and text-filled pictures. The OCR library from Iron Software may be used in .NET Console, Web, MVC, and Desktop Applications. The licensing procedure for commercial deployments is directly assisted by the development team. The most recent versions of Visual Studio are compatible with IronOCR.

Advantage of IronOCR

• IronOCR can read paper documents, barcodes, and QR codes from a variety of images or PDF files using the most recent Tesseract 5 engine. The integration of OCR into desktop, console, and Web Applications is made simpler by this package.
• Execute OCR with the aid of IronOCR, turning scanned PDFs into searchable PDFs.
• Worldwide, IronOCR supports 127 distinct languages in addition to word lists and bespoke languages.
• More than 20 distinct kinds of barcodes and QR codes can be scanned with IronOCR.
• Both barcode data and plain text output are available from IronOCR. By employing an alternate structured data object paradigm, developers can retrieve all content for direct insertion into a system. This applies to online applications' organized headings, paragraphs, lines, words, and characters.

Invoice Processing Using IronOCR

Receipt data may be extracted and accessed with the help of IronOCR, a potent OCR library. Without sacrificing data privacy, you may use IronOCR to snap a picture of a receipt and turn it into machine-readable text that can be readily analyzed and processed.

Here is a demonstration of how receipt OCR functions using IronOCR to extract text from a receipt.

// This code demonstrates how to use IronOCR to extract text from a receipt image.
var ocr = new IronTesseract();
ocr.Language = OcrLanguage.EnglishBest; // Set the OCR language to English
ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5; // Use Tesseract version 5

using (OcrInput ocrInput = new OcrInput("Demo.gif")) // Initialize OCR input with the image "Demo.gif"
{
    OcrResult ocrResult = ocr.Read(ocrInput); // Perform OCR reading
    // Extract the total price from the OCR result if present
    var totalPrice = ocrResult.Text.Contains("Total Current Charges") 
        ? ocrResult.Text.Split("Total Current Charges")[1].Split("\n")[0] 
        : "";
    Console.WriteLine("Total Current Charges : " + totalPrice); // Output the extracted total price
}

// This code demonstrates how to use IronOCR to extract text from a receipt image.
var ocr = new IronTesseract();
ocr.Language = OcrLanguage.EnglishBest; // Set the OCR language to English
ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5; // Use Tesseract version 5

using (OcrInput ocrInput = new OcrInput("Demo.gif")) // Initialize OCR input with the image "Demo.gif"
{
    OcrResult ocrResult = ocr.Read(ocrInput); // Perform OCR reading
    // Extract the total price from the OCR result if present
    var totalPrice = ocrResult.Text.Contains("Total Current Charges") 
        ? ocrResult.Text.Split("Total Current Charges")[1].Split("\n")[0] 
        : "";
    Console.WriteLine("Total Current Charges : " + totalPrice); // Output the extracted total price
}

Imports Microsoft.VisualBasic

' This code demonstrates how to use IronOCR to extract text from a receipt image.
Dim ocr = New IronTesseract()
ocr.Language = OcrLanguage.EnglishBest ' Set the OCR language to English
ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5 ' Use Tesseract version 5

Using ocrInput As New OcrInput("Demo.gif") ' Initialize OCR input with the image "Demo.gif"
	Dim ocrResult As OcrResult = ocr.Read(ocrInput) ' Perform OCR reading
	' Extract the total price from the OCR result if present
	Dim totalPrice = If(ocrResult.Text.Contains("Total Current Charges"), ocrResult.Text.Split("Total Current Charges")(1).Split(vbLf)(0), "")
	Console.WriteLine("Total Current Charges : " & totalPrice) ' Output the extracted total price
End Using

The IronTesseract object is created in the code snippet above to start the OCR process. An OcrInput object is constructed to facilitate the addition of one or more image files. The path for an additional image is needed utilizing the OcrInput object's Add method, allowing multiple invoice images to be included as needed. The Read method of the IronOCR object is triggered to parse the image documents and extract the results into the OCR result, converting text from images into a string. In the above code, the total price is extracted from the invoice.

The sample invoice

The text "Total Current Charges" from the previously provided image is displayed in the output below, proving that the total was correctly extracted from the image.

The total price is extracted and displayed in the Console Application

Conclusion

There are different OCR tools available in the market that help to process data from the invoice. OCR processing invoices allows reading the data from the given invoice image into text. The first three OCR tools aid in processing invoice data and reduce manual data entry work, which automates invoice scanning and data validation. Some OCR tools require an active internet connection and the cost of the tool is also high. It is supported by a few environments.

On the other hand, several .NET projects, including .NET Framework Standard 2, .NET Framework 4.5, and .NET Core 2, 3, and 5, are supported by IronOCR. It also functions with more recent technologies like Azure, Mono, and Xamarin. IronOCR improves Tesseract's output and fixes incorrectly scanned texts or images by using IronOCR technologies. The NuGet Package controls the intricate Tesseract dictionary system. So IronOCR is the best invoice OCR software for invoice automation and extracts data with a few lines of code.

IronOCR provides a seamless experience without the need for additional configurations, supporting various image formats, PDF files, and MultiFrame TIFF.
