{
// Configure the text color and font attributes

GroupDocs.Signature for .NET empowers your organization by enhancing document workflows through the addition of customizable text signatures across popular file formats. Easily manage the appearance, positioning, and content of these signatures to suit your specific needs.
Apply a diverse range of signatures—including text, images, barcodes, QR codes, and stamps—onto any page of supported documents. Leverage metadata to embed hidden content, while protecting sensitive information through the use of digital certificates.
Ensure the validity and integrity of your signed documents by utilizing our robust signature verification tools. Conduct searches to retrieve a comprehensive list of all signatures within a document for further analysis.
Easily modify the content, visual properties, or positioning of previously embedded signatures. When necessary, remove unwanted signatures to maintain accurate and relevant document content.
Implement document-specific text signatures, such as watermarks for Word documents or stickers for PDFs, to provide an additional layer of customization and control.
// Select the document to be signed
using (Signature signature = new Signature("input.pdf"))
{
// Formulate text options with the specified content
TextSignOptions options = new TextSignOptions("Rescheduled to 03/04/2025")
{
// Define the dimensions and position of the signature on the page
Left = 100,
Top = 180,
Width = 230,
Height = 30,
// Implement padding from the page edges for signatures
Margin = new Padding() { Top = 20, Right = 20 },
// Customize the text color and font style
ForeColor = Color.OrangeRed,
Font = new SignatureFont { Size = 12, FamilyName = "Comic Sans MS" },
// Incorporate a border around the text signature
Border = new Border()
{
Color = Color.OrangeRed,
DashStyle = DashStyle.Dash,
Transparency = 0.5,
Visible = true,
Weight = 2
},
// Apply background customization if necessary
Background = new Background()
{
Color = Color.LightYellow,
Transparency = 0.8
},
// Optionally save the text as an image to ensure compatibility
SignatureImplementation = TextSignatureImplementation.Image
};
// Save the document with the integrated text signature
SignResult result = signature.Sign("output.pdf", options);
