Delete Barcode from Document

Introduction

GroupDocs.Signature for .NET is a powerful library that enables developers to seamlessly work with digital signatures, stamps, and barcodes within .NET applications. In this tutorial, we will guide you through the process of deleting a barcode from a document using GroupDocs.Signature for .NET.

Prerequisites

Before we get started, ensure that you have the following prerequisites:

  • Basic knowledge of C# programming language.
  • Visual Studio installed on your system.
  • GroupDocs.Signature for .NET library installed. You can download it from here.
  • A sample document with a barcode that you want to delete.

Import Namespaces

First, make sure to import the necessary namespaces into your C# code:

using System;
using System.IO;
using System.Collections.Generic;
using GroupDocs.Signature;
using GroupDocs.Signature.Domain;
using GroupDocs.Signature.Options;

Let’s break down the process of deleting a barcode from a document into simple steps:

Step 1: Define File Paths

string filePath = "sample_multiple_signatures.docx";
string fileName = Path.GetFileName(filePath);
string outputFilePath = Path.Combine("Your Document Directory", "DeleteBarcode", fileName);

Ensure to replace "sample_multiple_signatures.docx" with the path to your document containing the barcode.

Step 2: Copy the Source File

File.Copy(filePath, outputFilePath, true);

This step ensures that we are working with a copy of the original document to preserve the original file.

Step 3: Initialize GroupDocs.Signature

using (Signature signature = new Signature(outputFilePath))
{
    // Your code goes here
}

Initialize the Signature object by passing the path to the document copy created in the previous step.

Step 4: Search for Barcode Signatures

BarcodeSearchOptions options = new BarcodeSearchOptions();
List<BarcodeSignature> signatures = signature.Search<BarcodeSignature>(options);

Create an instance of BarcodeSearchOptions and use it to search for barcode signatures within the document.

Step 5: Delete Barcode Signature

if (signatures.Count > 0)
{
    BarcodeSignature barcodeSignature = signatures[0];
    bool result = signature.Delete(barcodeSignature);
    if (result)
    {
        Console.WriteLine($"Signature with Barcode '{barcodeSignature.Text}' and encode type '{barcodeSignature.EncodeType.TypeName}' was deleted from document ['{fileName}'].");
    }
    else
    {
        Helper.WriteError($"Signature was not deleted from the document! Signature with Barcode '{barcodeSignature.Text}' and encode type '{barcodeSignature.EncodeType.TypeName}' was not found!");
    }
}

Check if barcode signatures are found in the document. If found, delete the first barcode signature found.

Conclusion

In this tutorial, we have learned how to delete a barcode from a document using GroupDocs.Signature for .NET. By following the step-by-step guide, you can seamlessly integrate barcode deletion functionality into your .NET applications.
