Learn how to implement OCR invoice scanning using Python, C#, and Java.

ocr-invoice-scanning_in_csharp.cs

// This code example demonstrates how to read and extract information from an invoice in C#.
using Aspose.OCR;

// Initialize an instance of AsposeOcr
Aspose.OCR.AsposeOcr api = new Aspose.OCR.AsposeOcr();

OcrInput images = new OcrInput(InputType.SingleImage)
{
    "invoice.jpg"
};

// Recognize invoice screenshot image with OCR
var result = api.RecognizeInvoice(images);

// Display the recognized text from invoice
foreach (var image in result)
{
    Console.WriteLine(image.RecognitionText);
}
