Extract Barcodes from Document Page

Introduction

In this tutorial, we’ll guide you through the process of extracting barcodes from a document page using GroupDocs.Parser for .NET. GroupDocs.Parser is a powerful document parsing library that allows developers to extract text, metadata, and even barcodes from various document formats.

Prerequisites

Before you begin, ensure you have the following in place:

• Basic knowledge of C# and .NET programming.
• Visual Studio installed on your system.
• GroupDocs.Parser for .NET library downloaded and referenced in your project.

Import Namespaces

First, import the necessary namespaces for using GroupDocs.Parser functionalities in your C# project:

using GroupDocs.Parser.Data;
using System;
using System.Collections.Generic;

Step 1: Load the Document

Begin by initializing the Parser object with the path to your sample document file:

using (Parser parser = new Parser("YourSampleFile.docx"))
{
    // Check if the document supports barcode extraction
    if (!parser.Features.Barcodes)
    {
        Console.WriteLine("Document doesn't support barcode extraction.");
        return;
    }

    // Proceed to barcode extraction
}

Step 2: Extract Barcodes

Once you’ve verified that the document supports barcode extraction, proceed to extract barcodes from a specific page (e.g., page 1) of the document:

// Extract barcodes from the first document page (page index is 0-based)
IEnumerable<PageBarcodeArea> barcodes = parser.GetBarcodes(0);

// Iterate over each barcode found
foreach (PageBarcodeArea barcode in barcodes)
{
    // Print the page index
    Console.WriteLine("Page: " + barcode.Page.Index.ToString());
    
    // Print the barcode value
    Console.WriteLine("Value: " + barcode.Value);
}

Step 3: Iterate and Display Barcodes

Finally, iterate through the extracted barcodes and display their corresponding page index and values:

foreach (PageBarcodeArea barcode in barcodes)
{
    // Print the page index
    Console.WriteLine("Page: " + barcode.Page.Index.ToString());
    
    // Print the barcode value
    Console.WriteLine("Value: " + barcode.Value);
}

Conclusion

In this tutorial, you’ve learned how to use GroupDocs.Parser for .NET to extract barcodes from a document page efficiently. This library simplifies the process of working with documents in your .NET applications, allowing you to access valuable information like barcodes seamlessly.
