Methods
FromSigner(Func<String>, Func<Int32>, Func<Stream, Byte[]>)
Initializes a new instance of the PdfDigitalSignatureSaveOptions class from the specified signer.
public static PdfDigitalSignatureSaveOptions FromSigner(Func<string> signatureFormatFunc, Func<int> estimatedSignatureLengthFunc, Func<Stream, byte[]> computeSignatureFunc)Public Shared Function FromSigner(signatureFormatFunc As Func(Of String), estimatedSignatureLengthFunc As Func(Of Integer), computeSignatureFunc As Func(Of Stream, Byte())) As PdfDigitalSignatureSaveOptionsParameters
A delegate that returns the format of the signature content that the signer produces.
A delegate that returns the estimated length of the signature content (in bytes) that should be large enough to contain the entire data returned by the computeSignatureFunc delegate.
A delegate called when saving the PDF file that takes the PDF file stream (without signature's Contents entry) as an input and returns the signature that will be set as the value of the signature's Contents entry.
Returns
A new instance of the PdfDigitalSignatureSaveOptions class from the specified signer.
