public class PdfSignatureAppearance

Public Class PdfSignatureAppearance

Remarks

The PdfSignatureAppearance class properties allow you to customize the signature appearance that consists of two components:

Signature – a graphic that identifies the signer on the left side of the signature (a photo, scanned signatures and so on).
Signature details – data that appears to the right of the signature.

Call the SetImageData method to specify an image displayed on the left side of the signature. If no image is specified, the signer name is displayed. The name is extracted from the signing certificate or the PdfSignatureBuilder.Name property. Set the AppearanceType property to None to display only signature details.

Call the PdfSignatureBuilder.SetSignatureAppearance() method and pass the PdfSignatureAppearance object as a parameter to apply changes to the signature. The SetSignatureAppearance method call discards an image set by the PdfSignatureBuilder.SetImageData() method.

Example

The code sample below customizes the signature appearance:

// Apply a signature to an existing form field
var santuzzaSignature = new PdfSignatureBuilder(pkcs7Signature, "Sign");

santuzzaSignature.Reason = "I Agree";

// Specify signature appearance parameters:

// Specify what information to display:

// Set display format for date and time:

// Change font settings for signature details:

signatureAppearance.SignatureDetailsFont.Italic = true;

// Apply changes:
santuzzaSignature.SetSignatureAppearance(signatureAppearance);
