function CreateSigDictForCustomSigning(in_filter_name, in_subfilter_type, in_contents_size_to_reserve);

Parameters

in_filter_name: Type: SystemString
the Filter name to use, representing the name of the signature handler that will be used to sign and verify the signature (e.g. Adobe.PPKLite)
in_subfilter_type: Type: pdftron.PDFDigitalSignatureFieldSubFilterType
the SubFilter name to use, representing an interoperable signature type identifier for third-party verification (e.g. adbe.pkcs7.detached, ETSI.CAdES.detached, etc.)
in_contents_size_to_reserve: Type: SystemUInt32
The size of the empty Contents entry to create. For security reasons, set the contents size to a value greater than but as close as possible to the size you expect your final signature to be.
