Setting Up GroupDocs.Signature for .NET

To begin using GroupDocs.Signature for .NET, you need to install the library and configure a basic setup within your project.

Installation

Follow one of the methods mentioned above to add GroupDocs.Signature to your project. Once installed, ensure your project is configured to use it by referencing it in your code files.

License Initialization

After acquiring a license, initialize it as follows:

SignatureConfig signConfig = new SignatureConfig();
signConfig.LicensePath = "path/to/your/license.lic";
Signature signature = new Signature("Sample.pdf", signConfig);

This setup will allow you to access all features of GroupDocs.Signature without limitations.

Implementation Guide

Now, let’s dive into implementing each feature using HIBC QR Codes with GroupDocs.Signature for .NET.

Sign Document with HIBC LIC QR-Code

Overview

Signing a document with an HIBC LIC QR Code ensures compliance and traceability in licensing scenarios. This section will guide you through creating and embedding a QR code within your PDF documents.

Implementation Steps

Step 1: Configure the Source and Output Paths

Define where your source document is located and where the signed output should be saved:

string sourceFilePath = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "Sample.pdf");
string outputPath = Path.Combine("YOUR_OUTPUT_DIRECTORY", "SignWithHIBCLICQR");
string destinFilePath = Path.Combine(outputPath, "SignedDocumentWithHIBCLICQR.pdf");

Step 2: Create QR Code Sign Options

Configure your QR code with specific text and settings:

using (Signature signature = new Signature(sourceFilePath))
{
    var hibcLic_QR_Options = new QrCodeSignOptions("A123PROD30917/75#422011907#GP293", QrCodeTypes.HIBCLICQR)
    {
        Left = 1,
        Top = 1,
        ReturnContent = true,
        ReturnContentType = FileType.PNG
    };

    // Sign the document with these options.
    signature.Sign(destinFilePath, hibcLic_QR_Options);
}

Explanation:

QrCodeSignOptions sets up the QR code’s appearance and content. Here, we specify HIBC LIC QR Code type and position it on the document.
ReturnContent set to true allows you to retrieve a rendered image of the signed document.

Troubleshooting Tips

Ensure the document path is correctly specified.
Verify that GroupDocs.Signature is properly licensed for full functionality.

Sign Document with HIBC LIC Aztec Code

Overview

The Aztec code offers another form of encoding, suitable for high-density information storage. This section focuses on embedding an Aztec code into your documents using GroupDocs.Signature.

Implementation Steps

Step 1: Configure Paths

Similar to the previous feature, define your file paths:

string sourceFilePath = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "Sample.pdf");
string outputPath = Path.Combine("YOUR_OUTPUT_DIRECTORY", "SignWithHIBCLICAztec");
string destinFilePath = Path.Combine(outputPath, "SignedDocumentWithHIBCLICAztec.pdf");

Step 2: Configure Aztec Code Options

Set up your Aztec code using GroupDocs.Signature:

using (Signature signature = new Signature(sourceFilePath))
{
    var hibcLic_AZ_Options = new QrCodeSignOptions("A123PROD30917/75#422011907#GP293", QrCodeTypes.HIBCLICAztec)
    {
        Left = 1,
        Top = 200,
        ReturnContent = true,
        ReturnContentType = FileType.PNG
    };

    signature.Sign(destinFilePath, hibcLic_AZ_Options);
}

Explanation:

The QrCodeSignOptions is used again here but with the Aztec code type.
Positioning (Top, Left) and content retrieval settings are similar to QR codes.

Troubleshooting Tips

Confirm that the file paths are accurate.
Ensure GroupDocs.Signature’s version supports Aztec Code types.

Sign Document with HIBC LIC DataMatrix

Overview

The DataMatrix code provides another robust method for storing data. This section demonstrates how to integrate a DataMatrix into your PDF documents.

Implementation Steps

Step 1: Set File Paths

As before, establish where your files are located:

string sourceFilePath = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "Sample.pdf");
string outputPath = Path.Combine("YOUR_OUTPUT_DIRECTORY", "SignWithHIBCLICDataMatrix");
string destinFilePath = Path.Combine(outputPath, "SignedDocumentWithHIBCLICDataMatrix.pdf");

Step 2: Create DataMatrix Sign Options

Configure and apply the DataMatrix code:

using (Signature signature = new Signature(sourceFilePath))
{
    var hibcLic_DM_Options = new QrCodeSignOptions("A123PROD30917/75#422011907#GP293", QrCodeTypes.HIBCLICDataMatrix)
    {
        Left = 1,
        Top = 400,
        ReturnContent = true,
        ReturnContentType = FileType.PNG
    };

    signature.Sign(destinFilePath, hibcLic_DM_Options);
}

Explanation:

QrCodeSignOptions is used to set up the DataMatrix code’s appearance and content.
Positioning (Top, Left) and retrieval settings follow the same pattern as previous codes.

Troubleshooting Tips

Ensure all file paths are correctly specified.
Verify that GroupDocs.Signature supports DataMatrix Code types in your version.

Sign Document with HIBC PAS QR-Code

Overview

Signing documents with an HIBC PAS QR Code enhances product tracking and traceability. This section guides you through embedding a PAS QR code into PDFs using GroupDocs.Signature.

Implementation Steps

Step 1: Configure the Source and Output Paths

Define where your source document is located and where the signed output should be saved:

string sourceFilePath = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "Sample.pdf");
string outputPath = Path.Combine("YOUR_OUTPUT_DIRECTORY", "SignWithHIBCPASQR");
string destinFilePath = Path.Combine(outputPath, "SignedDocumentWithHIBCPASQR.pdf");

Step 2: Create QR Code Sign Options

Configure your PAS QR code with specific text and settings:

using (Signature signature = new Signature(sourceFilePath))
{
    var hibcPas_QR_Options = new QrCodeSignOptions("PAS123456789012", QrCodeTypes.HIBCPASQR)
    {
        Left = 1,
        Top = 500,
        ReturnContent = true,
        ReturnContentType = FileType.PNG
    };

    // Sign the document with these options.
    signature.Sign(destinFilePath, hibcPas_QR_Options);
}

Explanation:

QrCodeSignOptions is configured for HIBC PAS QR Code type and positioned on the document.
ReturnContent set to true retrieves a rendered image of the signed document.

Troubleshooting Tips

Ensure all paths are correctly specified.
Verify that GroupDocs.Signature supports PAS QR Code types in your version.

Conclusion

By following this guide, you can efficiently integrate HIBC LIC and PAS QR Codes into PDF documents using GroupDocs.Signature for .NET. This process enhances document security, traceability, and compliance across various industries. For further customization and advanced features, refer to the GroupDocs documentation.
