Extract Barcodes from Document with Options

Introduction

In this tutorial, we’ll walk through the process of extracting barcodes from a document using GroupDocs.Parser for .NET. GroupDocs.Parser is a powerful library that allows you to extract text, metadata, and barcodes from various document formats such as PDF, Microsoft Word, Excel, and more.

Prerequisites

Before you begin, make sure you have the following prerequisites in place:

  1. Development Environment: Ensure you have Visual Studio installed on your machine.
  2. GroupDocs.Parser Library: Download and install the GroupDocs.Parser for .NET library from here.
  3. Sample Document: Prepare a sample document (e.g., PDF, DOCX) containing barcodes for extraction.

Import Namespaces

First, you need to import the necessary namespaces into your C# project to utilize the GroupDocs.Parser functionalities.

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

Step 1: Create an Instance of Parser Class

To get started, create an instance of the Parser class by passing the path to your sample document.

using (Parser parser = new Parser("YourSampleFile.pdf"))
{
    // Code to be added in the next steps
}

Step 2: Check Barcode Extraction Support

Next, check if the document supports barcode extraction using the Features property of the Parser instance.

if (!parser.Features.Barcodes)
{
    Console.WriteLine("Document doesn't support barcode extraction.");
    return;
}

Step 3: Define Barcode Extraction Options

Now, specify the options for barcode extraction using BarcodeOptions. You can set parameters such as quality modes and barcode types.

BarcodeOptions options = new BarcodeOptions(QualityMode.Low, QualityMode.Low, "QR");

Step 4: Extract Barcodes from the Document

Use the GetBarcodes method of the Parser class to extract barcodes based on the defined options.

IEnumerable<PageBarcodeArea> barcodes = parser.GetBarcodes(options);

Step 5: Iterate and Display Extracted Barcodes

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

foreach (PageBarcodeArea barcode in barcodes)
{
    Console.WriteLine("Page: " + barcode.Page.Index.ToString());
    Console.WriteLine("Value: " + barcode.Value);
}

Conclusion

In this tutorial, we’ve learned how to extract barcodes from a document using GroupDocs.Parser for .NET. This process involves creating a Parser instance, defining extraction options, and iterating through the extracted barcodes. GroupDocs.Parser simplifies the task of barcode extraction from various document formats, enabling efficient document processing within your .NET applications.
