In this section, we’ll guide you through implementing specific features using GroupDocs.Signature for .NET.

Searching for Barcode Signatures

This feature allows you to search documents for barcode signatures with customizable options.

Initializing the Search Options

using GroupDocs.Signature.Options;

// Create and configure BarcodeSearchOptions
BarcodeSearchOptions options = new BarcodeSearchOptions()
{
    AllPages = false, // Search only specific pages
    PageNumber = 1,   // Specify page number to search on
    PagesSetup = new PagesSetup() 
    {
        FirstPage = true,
        LastPage = true,
        OddPages = false,
        EvenPages = false
    },
    EncodeType = BarcodeTypes.Code128, // Type of barcode to search for
    MatchType = TextMatchType.Contains, // Search barcodes containing specific text
    Text = "12345" // Text to match within the barcode
};

using System;
using GroupDocs.Signature.Domain;

// Search document and collect signatures
List<Signature> signatures = signature.Search(options);

foreach (var sign in signatures)
{
    Console.WriteLine($"Found Signature: {sign.Text}");
}

Key Configuration Options

  • AllPages: Set to false to limit the search to specified pages.
  • EncodeType: Defines barcode type, such as Code128.
  • MatchType and Text: Customize text matching within barcodes.

Troubleshooting Tips:

  • Ensure correct file paths are provided.
  • Validate that the document contains the expected barcode types.
  • Check for any discrepancies in the page setup options.

Practical Applications

Here are some real-world scenarios where this feature can be beneficial:

  1. Invoice Verification: Automate the validation of barcodes on invoices to ensure authenticity and accuracy.
  2. Contract Management: Search contracts for specific barcode signatures, streamlining approval workflows.
  3. Inventory Tracking: Use barcode searches within shipment documents to track inventory efficiently.

Performance Considerations

To enhance performance while using GroupDocs.Signature:

  • Optimize document loading by handling large files in chunks if possible.
  • Manage memory effectively by disposing of objects properly after use.
  • Utilize asynchronous methods for non-blocking operations, improving application responsiveness.

Best Practices:
