Working with Barcodes in Templates

Introduction

In this tutorial, we’ll explore how to efficiently extract data from documents using templates with GroupDocs.Parser for .NET. GroupDocs.Parser simplifies the process of data extraction by allowing you to define templates for specific data types, such as barcodes, and then parse documents according to these templates.

Prerequisites

Before we begin, ensure you have the following set up:

• GroupDocs.Parser for .NET: You can download the library from here.
• Sample Document: Prepare a sample file (e.g., PDF, DOCX) that contains the data you want to extract.

Import Namespaces

First, include the necessary namespaces in your C# code:

using GroupDocs.Parser.Data;
using GroupDocs.Parser.Templates;
using System;

Step 1: Define a Barcode Field

Define a barcode field within a template. This example sets up a QR code field:

TemplateBarcode barcode = new TemplateBarcode(
    new Rectangle(new Point(590, 80), new Size(150, 150)),
    "QR");

Here, Rectangle defines the position and size of the barcode field on the document.

Step 2: Create a Template

Create a template and add the barcode field to it:

Template template = new Template(new TemplateItem[] { barcode });

Step 3: Parse the Document Using the Template

Instantiate the Parser class with your document file path and parse the document using the defined template:

using (Parser parser = new Parser("YourSampleFile.pdf"))
{
    DocumentData data = parser.ParseByTemplate(template);
    // Print extracted data
    for (int i = 0; i < data.Count; i++)
    {
        Console.Write(data[i].Name + ": ");
        PageBarcodeArea area = data[i].PageArea as PageBarcodeArea;
        Console.WriteLine(area == null ? "Not a template barcode field" : area.Value);
    }
}

This code snippet opens the document, applies the template, and extracts data based on the defined barcode field. It then prints the extracted data.

Conclusion

Using GroupDocs.Parser for .NET with templates simplifies the extraction of structured data from documents, especially when dealing with specific data types like barcodes. By following this guide, you can efficiently integrate document parsing capabilities into your .NET applications.
