Returns
signature data for a given signature field.
For example, your application must get the signature information
from a signed PDF document. You require the timestamp and subfilter
information to validate the signature with an external web service.
You use the Get Signature operation to retrieve the timestamp and
subfilter information from the digital signature.
For information about the General and Route Evaluation property
groups, see
Common operation properties
.
Input properties
Properties to specify the PDF document and signature field.
Input PDF
A
document
value
that contains a signature field for which data is retrieved.
If
you provide a literal value, clicking the ellipsis button opens
the Select Asset dialog box. (See
About Select Asset
.)
When you provide a PDF document that
has signature fields that are signed, it populates the Signature
Field Name property as a list. The list contains fully qualified
names of the signed signature fields in the PDF document.
Signature Field Name
A
string
value
that represents the name of the signature field that contains a
signature. The fully qualified name of the signature field must
be specified. When using a PDF document based on a form created
in Designer, the partial name of the signature field can be used.
For example,
form1[0].#subform[1].SignatureField3[3]
can
be specified as
SignatureField3[3]
.
If you
are getting signature fields from a PDF document, the partial name
of the signature field can also be used. For example,
form1[0].#subform[1].SignatureField3[3]
can
be specified as
SignatureField3[3]
. If multiple signature
fields exist with a similar partial name, the first signature field enumerated
with the same partial name is signed. It is recommended that a fully qualified
name is used to avoid these situations.
If you provide a
literal value for the Signature Field Name property and a literal
value is provided in the Input PDF property, a list appears. Select
one of the values from the list of fully qualified names. Each fully
qualified name represents a signed signature field in the provided
PDF document.
Output properties
Property to specify the signature data.
PDF Signature Result
The location in the process data model
to store the value that contains the signature and information about
the filter and subfilters. The filters and subfilters are used for
validating the signature. The value also contains information about certificates
that are embedded in the PDF document. The data type is a
PDFSignature
value.
