Remarks

NOTE: This class required the .NET Framework 2.0 or greater.

The signature can be of visible or invisible. Use this constructor to create a visible signature field. For creating a invisible field refer Sign(System.String,ceTe.DynamicPDF.Certificate) . A signature field that does not have corresponding entry at Sign(System.String,ceTe.DynamicPDF.Certificate) will behave as empty signature field and can be signed later. The visible signature field is divided into three panels.

• Left or Top Panel By default this panel holds the subject name of the given certificate.
• Right or Bottom Panel This panel is set to hold information related with certificate and the signer.
• Full Panel This panel constitutes complete area of the signature. It does not hold any default values, but can be used to show up full area text or image.
