// This example demonstrates the use of Optical Character Recognition (OCR) to parse invoice data
// from scanned PDF documents and raster images.

        static void Main(string[] args)

            // Create InvoiceParser instance
            using (InvoiceParser invoiceParser = new InvoiceParser("demo", "demo"))
            {
                // Enable Optical Character Recognition (OCR)
                // in .Auto mode (SDK automatically checks if needs to use OCR or not)
                invoiceParser.OCRMode = OCRMode.Auto;

                // Set OCR language
                // "eng" for english, "deu" for German, "fra" for French, etc. - according to files in "ocrdata" folder

How to Parse Invoice with OCR using ByteScout Document Parser SDK

In this tutorial, we will parse invoices with OCR using C#. Let’s copy the sample code and paste it into the Visual Studio editor. I added the sample code link in the description box below. To parse invoice data, we will use the ‘ByteScout Document Parser SDK’. You can add a reference to the document parser SDK DLL in the solution explorer. Right-click on reference and select add reference. Look at the ‘ByteScout Document Parser SDK’ and add.

Let’s copy the sample files from the folder. Then we will add our sample file in the solution explorer and set the copy to the output directory to ‘copy always’. Now set the sample template in the sample image. To make a new template, you may see the link in the description box below.

Then add your registration name and registration key and their related properties accordingly. You can get your license details in the ByteScout dashboard. After that enable the OCR mode to ‘auto’ and set the OCR resolution. We will also set the location of OCR language data files and you may set the OCR language to your own language according to files in OCR data. Our output will be in JSON format.

Now run the program and check out the JSON output.
