public class AcroSignatureField extends Object
Represents a digital signature field in an interactive AcroForm.
PDFxStream does not provide higher-level support for this type of field, and its value cannot be updated
(calling setValue(String) on an AcroSignatureField will result in an
UnsupportedOperationException exception being thrown).
However, all of a signature field's raw data may be accessed via getValue(), which will return a java.util.Map object containing dictionary values as specified by Section 8.6.3 ('Signature Fields') and Table 8.9.3 in the PDF document specification.
