Electronic Signature Types: Supports various types like text, image, QR-code, barcode, metadata, stamp, form-field, and digital signatures.
Search for Signatures: Ability to search for applied signatures such as text, barcode, QR-code, image, metadata, and form-field signatures.
Verify Signatures: Capable of verifying the authenticity of different signature types (text, digital, QR-code, etc.).
Document Information Extraction: Extracts file format, page count, and dimensions from signed documents.
Preview Document Pages: Allows generating page previews of signed documents for placement accuracy.

Electronic Signature Types

Text Signatures: Native text signatures, labels, watermarks with customizable visual settings.
Image Signatures: Add signatures with image effects like rotation, custom colors, and transparency.
Digital Signatures: Based on digital certificates (supporting PDF, Word, and Excel).
QR-Code Signatures: Includes customizable encoding, margins, and alignment options.

Form Field Signatures: Signatures integrated into form fields with full customization.

Sign Documents with:

Text Signatures: Apply customizable text signatures to documents.
Image Signatures: Add images as signatures with enhanced options.
Digital Signatures: Cryptographically sign documents using digital certificates.
Barcode/QR-Code Signatures: Use barcodes or QR-codes to sign documents.
Metadata Signatures: Embed hidden information within document metadata.
Form Field Signatures: Integrate signatures into form fields within documents.

Search for:

Text Signatures: Search documents for text-based signatures.
Image Signatures: Find image-based signatures with search criteria like dimensions.
Digital Signatures: Search for digitally signed documents and certificates.
QR-Code Signatures: Locate QR-code signatures with matching criteria.
Metadata Signatures: Search for signatures embedded in document metadata.
Form Field Signatures: Identify signatures applied within form fields.

Verify:

Text Signatures: Verify text-based signatures within documents.
Digital Certificates: Validate the authenticity of digital signatures.
QR-Code Signatures: Ensure the integrity of QR-code signatures.
Multiple Signature Types: Verify various signature types simultaneously.

Advanced Usage Topics

Sign a PDF File and Save it in DOCX Format using C# Code

using (Signature signature = new Signature("sample.pdf"))
{
    // create QRCode option with predefined QRCode text
    QRCodeSignOptions signOptions = new QRCodeSignOptions("JohnSmith")
    {
        EncodeType = QRCodeTypes.QR,
        Left = 100,
        Top = 100
    };
    PdfSaveOptions pdfSaveOptions = new PdfSaveOptions()
    {
        FileFormat = PdfSaveFileFormat.DocX,
        OverwriteExistingFiles = true
    };
    // sign document to file
    signature.Sign("SignedPdf.docx", signOptions, pdfSaveOptions);
}

Use C# to Search and Delete Signatures from a DOCX File

// initialize Signature instance
using (Signature signature = new Signature("signed.docx"))
{
    BarcodeSearchOptions options = new BarcodeSearchOptions();
    List<BarcodeSignature> signatures = signature.Search<BarcodeSignature>(options);
    List<BaseSignature> signaturesToDelete = new List<BaseSignature>();
    // collect signatures to delete
    foreach (BarcodeSignature temp in signatures)
    {
        if (temp.Text.Contains("John"))
        {
            signaturesToDelete.Add(temp);
        }
    }
    // delete signatures
    DeleteResult deleteResult = signature.Delete(signaturesToDelete);
    if (deleteResult.Succeeded.Count == signaturesToDelete.Count)
    {
        Console.WriteLine("All signatures were successfully deleted!");
    }
    else
    {
        Console.WriteLine($"Successfully deleted signatures : {deleteResult.Succeeded.Count}");
        Console.WriteLine($"Not deleted signatures : {deleteResult.Failed.Count}");
    }
    Console.WriteLine("List of deleted signatures:");
    foreach (BaseSignature temp in deleteResult.Succeeded)
    {
        Console.WriteLine($"Signature# Id:{temp.SignatureId}, Location: {temp.Left}x{temp.Top}. Size: {temp.Width}x{temp.Height}");
    }
}
