Add digital signatures to presentations and save them in different formats:

Create QRCodeSignOptions

Define the properties of your QR code signature using QrCodeSignOptions:

using GroupDocs.Signature.Options;

// Define QR code signature options
QrCodeSignOptions signOptions = new QrCodeSignOptions("JohnSmith")
{
    EncodeType = QrCodeTypes.QR,
    Left = 100, // Horizontal position on the page
    Top = 100   // Vertical position on the page
};

Set PresentationSaveOptions

Specify how you want to save your signed document using PresentationSaveOptions:

using GroupDocs.Signature.Domain;

// Configure save options for the signed presentation
PresentationSaveOptions saveOptions = new PresentationSaveOptions()
{
    FileFormat = PresentationSaveFileFormat.Tiff,
    OverwriteExistingFiles = true
};

Sign and Save

Sign your document and save it in the desired format:

using GroupDocs.Signature;

// Perform signing and saving process
SignResult result = signature.Sign("output/path", signOptions, saveOptions);

Setting Up Document Paths

Properly set paths for input and output files:

string sourceDocumentPath = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "Sample_Document.docx");
string signedOutputPath = Path.Combine("YOUR_OUTPUT_DIRECTORY", "SignedDocuments", "Signed_Document.pdf");
