How to eSign document with Text signature

Let’s try to add a text signature to a PDF programmatically.

To manipulate text signatures programmaticallyย GroupDocs.Signature providesย the TextSignOptionsย class and the whole workflow is as easy as follows:

  • Create a new instance ofย the Signatureย class and pass the source document path as a constructor parameter.
  • Instantiate the TextSignOptionsย object according to your requirements and specify the signature options.
  • Callย the Signย method ofย the Signatureย class instance and pass the TextSignOptionsย to it.

This example shows how to add a text signature to a document.

using (Signature signature = new Signature("sample.pdf"))
{
    TextSignOptions options = new TextSignOptions("John Smith")
    {
        // set signature position
        Left = 100,
        Top = 100,
        // set signature rectangle
        Width = 100,
        Height = 30,
        // set Text color and Font
        ForeColor = Color.Red,
        Font = new SignatureFont { Size = 12, FamilyName = "Comic Sans MS" }
    };
    // sign document to file
    signature.Sign("sample_signed.pdf", options);
}
